Upgrading an Oracle WebCenter Domain

3 Upgrading an Oracle WebCenter Domain

It is important to understand the general upgrade procedures for Oracle WebCenter and WebCenter Content. Also, in order to Upgrade Oracle WebCenter Domain, some additional component-specific tasks may be required.

The procedures outlined in the following sections describe the high-level process of upgrading a basic WebCenter domain to 12c (12.2.1.4.0). Most upgrades follow these general procedures, but the actual upgrade procedures you will perform depend on which components are being upgraded. There may be additional pre- or post- upgrade procedures associated with your components. Therefore, you will need to locate the upgrade procedures for each component in your pre-upgrade environment to complete the domain upgrade.

For example, if your Oracle WebCenter domain includes Oracle WebCenter Content and WebCenter Portal, you would need to follow the procedures described in Upgrading Oracle WebCenter Content and Upgrading Oracle WebCenter Portal 11g Installations.

About the Oracle WebCenter Upgrade Process
Review the process flow for upgrading WebCenter products to get a better understanding of the upgrade procedures and when you will perform them.
Installing a Product Distribution
Before beginning your upgrade, download Oracle Fusion Middleware Infrastructure and the WebCenter Content distributions on the target system and install them using Oracle Universal Installer.
Creating the Required 12c Schemas with the RCU
When upgrading, you must create the required schemas. You can use the Repository Creation Utility (RCU) to create customized schemas or, optionally, you can use the Upgrade Assistant to create schemas using the default schema settings. This procedure describes how to create schemas using the RCU. Information about using the Upgrade Assistant to create schemas is covered in the upgrade procedures.
Running a Pre-Upgrade Readiness Check
To identify potential issues with the upgrade, Oracle recommends that you run a readiness check before you start the upgrade process. Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success.
Stopping Servers and Processes
Before you run the Upgrade Assistant to upgrade your schemas and configurations, you must shut down all of the pre-upgrade processes and servers, including the Administration Server and any managed servers.
Upgrading Product Schemas
After stopping servers and processes, use the Upgrade Assistant to upgrade supported product schemas to the current release of Oracle Fusion Middleware.
About Reconfiguring the Domain
Run the Reconfiguration Wizard to reconfigure your domain component configurations to 12c (12.2.1.4.0).
Upgrading Domain Component Configurations
After reconfiguring the domain, use the Upgrade Assistant to upgrade the domain component configurations inside the domain to match the updated domain configuration.
Performing Post-Upgrade Configuration Tasks
You may have to perform additional configuration tasks after an upgrade depending on which components are in your deployment.

About the Oracle WebCenter Upgrade Process

Review the process flow for upgrading WebCenter products to get a better understanding of the upgrade procedures and when you will perform them.

Note:

If you have a multi-node environment and want to perform this upgrade without stopping your servers, see Performing a Reduced Downtime Upgrade.

This process flow shows the high-level procedures for upgrading a WebCenter domain to 12c (12.2.1.4.0). The actual procedures you will perform depends on your pre-upgrade environment and the components you will be upgrading.

Figure 3-1 Upgrading Oracle WebCenter to 12c (12.2.1.4.0)

Description of "Figure 3-1 Upgrading Oracle WebCenter to 12c (12.2.1.4.0)"

Task	Description
Required Complete all of the Oracle Fusion Middleware standard pre-upgrade tasks, as well as any additional component-specific tasks you may be required to perform.	Pre-Upgrade Tasks for Oracle WebCenter Components
Required Install the product distributions for all the products that are part of the domain.	Note that in 12c, the WebLogic Server and JRF are part of the Infrastructure distribution and must be installed first. The binaries should be installed into a new Oracle home on the same host as the existing deployment. Only install binaries for products that exist on the existing deployment. Adding new products can only be done after the upgrade is complete.
For 11g to 12c Upgrade Only: Run the 12c Repository Creation Utility (RCU) to create the required 12c schemas (`_STB` and `_OPSS`). The Service Table (`_STB`) schema is required in 12c. The OPSS (`_OPSS`) schema is required if an OID-based policy store was used in 11g.	If you are upgrading from a previous 12c release, then you will already have these schemas in your repository.
Optional Run a pre-upgrade readiness check with the Upgrade Assistant.	When run in `-readiness` mode, the Upgrade Assistant performs a read-only check to determine if there might be problems in the starting point environment that would prevent a successful upgrade. The checks vary by component and a complete report is generated to help troubleshoot any potential issues.
Required Stop the Administration Server, Managed Servers and any other running applications in your existing deployment.	Failure to shut down the existing environment during the upgrade can corrupt your schemas and/or component configurations.
Required Run the Upgrade Assistant to upgrade individually selected schemas or all schemas used by the domain.	Oracle recommends that you allow the Upgrade Assistant to upgrade all schemas within the selected domain whenever possible.
Required Run the Reconfiguration Wizard to reconfigure the domain. The Reconfiguration Wizard is a new tool in Oracle Fusion Middleware 12c.
WebCenter Portal and Sites Users Only: Run the Upgrade Assistant (again) to upgrade any remaining component configurations. WebCenter Content Users Only: You will not run the Upgrade Assistant as the necessary configuration changes are performed automatically at server startup (post upgrade) without user intervention.	Upgrading Domain Component Configurations
WebCenter Portal Users Only: You must complete a set of additional procedures to upgrade Oracle WebCenter Portal to 12c.	Upgrading Oracle WebCenter Portal 11g Installations
Required Complete all of the required post-upgrade tasks described in your component-specific documentation. Some components will not work correctly if these tasks are not performed after the upgrade.	Performing Post-Upgrade Configuration Tasks
Required Restart the administration server and the managed servers.
Required Verify the upgrade was successful (applications function as expected, etc.)	Verifying the New Applications Work as Expected
Optional Upgrade WebCenter for a cluster topology, if applicable	Upgrading WebCenter in a Clustered Topology

Installing a Product Distribution

Before beginning your upgrade, download Oracle Fusion Middleware Infrastructure and the WebCenter Content distributions on the target system and install them using Oracle Universal Installer.

Note:

When Infrastructure is required for the upgrade, you must install the Oracle Fusion Middleware distribution first before you install other Fusion Middleware products.

To install the 12c (12.2.1.4.0) distributions:

Sign in to the target system.
Download the following from Oracle Technology Network or Oracle Software Delivery Cloud to your target system:
- Oracle Fusion Middleware Infrastructure (fmw_12.2.1.4.0_infrastructure_generic.jar)
- Oracle WebCenter Content (fmw_12.2.1.4.0_wccontent_generic.jar)
Change to the directory where you downloaded the 12c (12.2.1.4.0) product distribution.
Start the installation program for Oracle Fusion Middleware Infrastructure:
- (UNIX) JDK_HOME/bin/java -jar fmw_12.2.1.4.0_infrastructure.jar
- (Windows) JDK_HOME\bin\java -jar fmw_12.2.1.4.0_infrastructure.jar

After your Infrastructure installation is complete, you will install the remaining distributions the same way using the correct distribution names. For example, to start the installation program for Oracle WebCenter Content, use fmw_12.2.1.4.0_wccontent_generic.jar as the distribution name

On UNIX operating systems, the Installation Inventory Setup screen appears if this is the first time you are installing an Oracle product on this host.
Specify the location where you want to create your central inventory. Make sure that the operating system group name selected on this screen has write permissions to the central inventory location, and click Next.

Note:
The Installation Inventory Setup screen does not appear on Windows operating systems.
On the Welcome screen, review the information to make sure that you have met all the prerequisites. Click Next.

Creating the Required 12c Schemas with the RCU

When upgrading, you must create the required schemas. You can use the Repository Creation Utility (RCU) to create customized schemas or, optionally, you can use the Upgrade Assistant to create schemas using the default schema settings. This procedure describes how to create schemas using the RCU. Information about using the Upgrade Assistant to create schemas is covered in the upgrade procedures.

Note:

If you are upgrading from a previous 12c release of Oracle Fusion Middleware, you do not need to re-create these schemas if they already exist. Refer to the steps below to identify the existing schemas in your domain.

The following schemas must exist before you upgrade. If you are upgrading from 12c, and you are not sure which schemas you currently have, refer to the steps below to identify the existing schemas in your domain. You do not need to re-create these schemas if they already exist.

Service Table schema (prefix_STB). This schema is required for domain-based upgrades. It stores basic schema configuration information (for example, schema prefixes and passwords) that can be accessed and used by other Oracle Fusion Middleware components during the domain creation. This schema is automatically created when you run the Repository Creation Utility (RCU), where you specify the existing schema owner prefix that you used for your other 12c schemas.

Note:

If the Service Table schema does not exist, you may encounter the error message UPGAST-00328 : The schema version registry table does not exist on this database. If that happens it is necessary to create the service table schema in order to run Upgrade Assistant
Oracle Platform Security Services (OPSS) schema (prefix_OPSS). This schema is required if you are using an OID-based security store in 12c. This schema is automatically created when you run the Repository Creation Utility (RCU). The only supported LDAP-based OPSS security store is Oracle Internet Directory (OID). An LDAP-based policy store is typically used in production environments. You do not need to reassociate an OID-based security store before upgrade. While the Upgrade Assistant is running, you can select the OPSS schema. The Upgrade Assistant upgrades the OID-based security store automatically.

Note:

The 12c OPSS database schema is required so that you can reference the 12c schema during the reconfiguration of the domain. Your domain continues to use the OID-based security store after the upgrade is complete.
Audit schemas (OPSS_AUDIT_VIEWER). If you have used an XML-based OPSS_AUDIT schema, or the Portal or Services schema in 11g, you will need to create a new 12c OPSS_AUDIT_VIEWER schema by using the RCU. Otherwise, the domain reconfiguration will fail.
WebLogic Server schemas (_WLS): As of release 12.2.1.3 the WebLogic Server schema is required before starting the upgrade.

To create the schemas with the RCU:

(Optional) If you are upgrading from 12c, and you wish to confirm the schemas which are present in your existing domain, then connect to the database as a user with DBA privileges, and run the following code from SQL*Plus:

SET LINE 120
COLUMN MRC_NAME FORMAT A14
COLUMN COMP_ID FORMAT A20
COLUMN VERSION FORMAT A12
COLUMN STATUS FORMAT A9
COLUMN UPGRADED FORMAT A8
SELECT MRC_NAME, COMP_ID, OWNER, VERSION, STATUS, UPGRADED FROM SCHEMA_VERSION_REGISTRY ORDER BY MRC_NAME, COMP_ID ;

Verify that a certified JDK already exists on your system by running java -version from the command line. For 12c (12.2.1.4.0), the certified JDK is 1.8.0_211 and later.
Ensure that the JAVA_HOME environment variable is set to the location of the certified JDK. For example:
- (UNIX) setenv JAVA_HOME=/home/Oracle/Java/jdk1.8.0_211
- (Windows) set JAVA_HOME=C:\home\Oracle\Java\jdk1.8.0_211
Add $JAVA_HOME/bin to $PATH.
Go to the oracle_common/bin directory.
On UNIX operating systems:

NEW_ORACLE_HOME/oracle_common/bin

On Windows operating systems:

NEW_ORACLE_HOME\oracle_common\bin

where NEW_ORACLE_HOME is your 12c (12.2.1.4.0) Oracle home.
Start the RCU:
- (UNIX) ./rcu
- (Windows) rcu.bat
On the Welcome screen, click Next.
On the Create Repository screen, select Create Repository and then select System Load and Product Load.
If you do not have DBA privileges, select Prepare Scripts for System Load. This will generate a SQL script containing all the same SQL statements and blocks that would have been called if the RCU were to execute the actions for the selected components. After the script is generated, a user with the necessary SYS or SYSDBA privileges can execute the script to complete the system load phase.
Click Next.

On the Database Connection Details screen, select the Database Type and enter the connection information for the database that hosts the 12c schemas. See the pertinent table below.

Running a Pre-Upgrade Readiness Check

To identify potential issues with the upgrade, Oracle recommends that you run a readiness check before you start the upgrade process. Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success.

About Running a Pre-Upgrade Readiness Check
You can run the Upgrade Assistant in -readiness mode to detect issues before you perform the actual upgrade. You can run the readiness check in GUI mode using the Upgrade Assistant or in silent mode using a response file.
Starting the Upgrade Assistant in Readiness Mode
Use the -readiness parameter to start the Upgrade Assistant in readiness mode.
Performing a Readiness Check with the Upgrade Assistant
Navigate through the screens in the Upgrade Assistant to complete the pre-upgrade readiness check.
Understanding the Readiness Report
After performing a readiness check for your domain, review the report to determine whether you need to take any action for a successful upgrade.

Parent topic: Upgrading an Oracle WebCenter Domain

About Running a Pre-Upgrade Readiness Check

You can run the Upgrade Assistant in -readiness mode to detect issues before you perform the actual upgrade. You can run the readiness check in GUI mode using the Upgrade Assistant or in silent mode using a response file.

The Upgrade Assistant readiness check performs a read-only, pre-upgrade review of your Fusion Middleware schemas and WebLogic domain configurations that are at a supported starting point. The review is a read-only operation.

The readiness check generates a formatted, time-stamped readiness report so you can address potential issues before you attempt the actual upgrade. If no issues are detected, you can begin the upgrade process. Oracle recommends that you read this report thoroughly before performing an upgrade.

You can run the readiness check while your existing Oracle Fusion Middleware domain is online (while other users are actively using it) or offline.

You can run the readiness check any number of times before performing any actual upgrade. However, do not run the readiness check after an upgrade has been performed, as the report results may differ from the result of pre-upgrade readiness checks.

Note:

To prevent performance from being affected, Oracle recommends that you run the readiness check during off-peak hours.

Parent topic: Running a Pre-Upgrade Readiness Check

Starting the Upgrade Assistant in Readiness Mode

Use the -readiness parameter to start the Upgrade Assistant in readiness mode.

To perform a readiness check on your pre-upgrade environment with the Upgrade Assistant:

Go to the oracle_common/upgrade/bin directory:
- (UNIX) ORACLE_HOME/oracle_common/upgrade/bin
- (Windows) ORACLE_HOME\oracle_common\upgrade\bin
Start the Upgrade Assistant.
- (UNIX) ./ua -readiness
- (Windows) ua.bat -readiness
Note:
If the DISPLAY environment variable is not set up properly to allow for GUI mode, you may encounter the following error:
```
Xlib: connection to ":1.0" refused by server
Xlib: No protocol specified 
```
To resolve this issue, set the DISPLAY environment variable to the system name or IP address of your local workstation, and rerun Upgrade Assistant.

If you continue to receive these errors after setting DISPLAY, try launching another GUI tool, such as vncconfig. If you see the same errors, your DISPLAY environment variable may still not be set correctly.
For information about other parameters that you can specify on the command line, see:

Upgrade Assistant Parameters

Parent topic: Running a Pre-Upgrade Readiness Check

Upgrade Assistant Parameters

When you start the Upgrade Assistant from the command line, you can specify additional parameters.

Table 3-5 Upgrade Assistant Command-Line Parameters

Parameter	Required or Optional	Description
`-readiness`	Required for readiness checks Note: Readiness checks cannot be performed on standalone installations (those not managed by the WebLogic Server).	Performs the upgrade readiness check without performing an actual upgrade. Schemas and configurations are checked. Do not use this parameter if you have specified the `-examine` parameter.
`-threads`	Optional	Identifies the number of threads available for concurrent schema upgrades or readiness checks of the schemas. The value must be a positive integer in the range 1 to 8. The default is 4.
`-response`	Required for silent upgrades or silent readiness checks	Runs the Upgrade Assistant using inputs saved to a response file generated from the data that is entered when the Upgrade Assistant is run in GUI mode. Using this parameter runs the Upgrade Assistant in silent mode (without displaying Upgrade Assistant screens).
`-examine`	Optional	Performs the examine phase but does not perform an actual upgrade. Do not specify this parameter if you have specified the `-readiness` parameter.
`-logLevel attribute`	Optional	Sets the logging level, specifying one of the following attributes: `TRACE` `NOTIFICATION` `WARNING` `ERROR` `INCIDENT_ERROR` The default logging level is `NOTIFICATION`. Consider setting the `-logLevel TRACE` attribute to so that more information is logged. This is useful when troubleshooting a failed upgrade. The Upgrade Assistant's log files can become very large if `-logLevel TRACE` is used.
`-logDir location`	Optional	Sets the default location of upgrade log files and temporary files. You must specify an existing, writable directory where the Upgrade Assistant creates log files and temporary files. The default locations are: (UNIX) `ORACLE_HOME/oracle_common/upgrade/logs` `ORACLE_HOME/oracle_common/upgrade/temp` (Windows) `ORACLE_HOME\oracle_common\upgrade\logs` `ORACLE_HOME\oracle_common\upgrade\temp`
`-help`	Optional	Displays all of the command-line options.

Parent topic: Starting the Upgrade Assistant in Readiness Mode

Performing a Readiness Check with the Upgrade Assistant

Navigate through the screens in the Upgrade Assistant to complete the pre-upgrade readiness check.

Readiness checks are performed only on schemas or component configurations that are at a supported upgrade starting point.

To complete the readiness check:

On the Welcome screen, review information about the readiness check. Click Next.
On the Readiness Check Type screen, select the readiness check that you want to perform:
- Individually Selected Schemas allows you to select individual schemas for review before upgrade. The readiness check reports whether a schema is supported for an upgrade or where an upgrade is needed.
  When you select this option, the screen name changes to Selected Schemas.
- Domain Based allows the Upgrade Assistant to discover and select all upgrade-eligible schemas or component configurations in the domain specified in the Domain Directory field.
  When you select this option, the screen name changes to Schemas and Configuration.
  Leave the default selection if you want the Upgrade Assistant to check all schemas and component configurations at the same time, or select a specific option:
  - Include checks for all schemas to discover and review all components that have a schema available to upgrade.
  - Include checks for all configurations to review component configurations for a managed WebLogic Server domain.
Click Next.
If you selected Individually Selected Schemas: On the Available Components screen, select the components that have a schema available to upgrade for which you want to perform a readiness check.
If you selected Domain Based: On the Component List screen, review the list of components that are present in your domain for which you want to perform a readiness check.

If you select a component that has dependent components, those components are automatically selected. For example, if you select Oracle Platform Security Services, Oracle Audit Services is automatically selected.
Depending on the components you select, additional screens may display. For example, you may need to:
- Specify the domain directory.
- Specify schema credentials to connect to the selected schema: Database Type, DBA User Name, and DBA Password. Then click Connect.
  
  Note:
  Oracle database is the default database type. Make sure that you select the correct database type before you continue. If you discover that you selected the wrong database type, do not go back to this screen to change it to the correct type. Instead, close the Upgrade Assistant and restart the readiness check with the correct database type selected to ensure that the correct database type is applied to all schemas.
- Select the Schema User Name option and specify the Schema Password.
  
  Note:
  The Upgrade Assistant automatically enables default credentials. If you are unable to connect, make sure that you manually enter the credentials for your schema before you continue.
Click Next to start the readiness check.
On the Readiness Summary screen, review the summary of the readiness checks that will be performed based on your selections.
If you want to save your selections to a response file to run the Upgrade Assistant again later in response (or silent) mode, click Save Response File and provide the location and name of the response file. A silent upgrade performs exactly the same function that the Upgrade Assistant performs, but you do not have to manually enter the data again.

For a detailed report, click View Log.

Click Next.
On the Readiness Check screen, review the status of the readiness check. The process can take several minutes.
If you are checking multiple components, the progress of each component displays in its own progress bar in parallel.

When the readiness check is complete, click Continue.
On the End of Readiness screen, review the results of the readiness check (Readiness Success or Readiness Failure):
- If the readiness check is successful, click View Readiness Report to review the complete report. Oracle recommends that you review the Readiness Report before you perform the actual upgrade even when the readiness check is successful. Use the Find option to search for a particular word or phrase within the report. The report also indicates where the completed Readiness Check Report file is located.
- If the readiness check encounters an issue or error, click View Log to review the log file, identify and correct the issues, and then restart the readiness check. The log file is managed by the command-line options you set.

Understanding the Readiness Report

After performing a readiness check for your domain, review the report to determine whether you need to take any action for a successful upgrade.

The format of the readiness report file is:

readiness<timestamp>.txt

Where, timestamp indicates the date and time of when the readiness check was run.

A readiness report contains the following information:

Table 3-6 Readiness Report Elements

Report Information	Description	Required Action
Overall Readiness Status: SUCCESS or FAILURE	The top of the report indicates whether the readiness check passed or completed with one or more errors.	If the report completed with one or more errors, search for FAIL and correct the failing issues before attempting to upgrade. You can re-run the readiness check as many times as necessary before an upgrade.
Timestamp	The date and time that the report was generated.	No action required.
Log file location `/oracle_common/upgrade/logs`	The directory location of the generated log file.	No action required.
Domain Directory	Displays the domain location	No action required.
Readiness report location `/oracle_common/upgrade/logs`	The directory location of the generated readiness report.	No action required.
Names of components that were checked	The names and versions of the components included in the check and status.	If your domain includes components that cannot be upgraded to this release, such as SOA Core Extension, do not attempt an upgrade.
Names of schemas that were checked	The names and current versions of the schemas included in the check and status.	Review the version numbers of your schemas. If your domain includes schemas that cannot be upgraded to this release, do not attempt an upgrade.
Individual Object Test Status: FAIL	The readiness check test detected an issue with a specific object.	Do not upgrade until all failed issues have been resolved.
Individual Object Test Status: PASS	The readiness check test detected no issues for the specific object.	If your readiness check report shows only the PASS status, you can upgrade your environment. Note, however, that the Readiness Check cannot detect issues with externals such as hardware or connectivity during an upgrade. You should always monitor the progress of your upgrade.
Completed Readiness Check of <Object> Status: FAILURE	The readiness check detected one or more errors that must be resolved for a particular object such as a schema, an index, or datatype.	Do not upgrade until all failed issues have been resolved.
Completed Readiness Check of <Object> Status: SUCCESS	The readiness check test detected no issues.	No action required.

Here is a sample Readiness Report file. Your report may not include all of these checks.

Stopping Servers and Processes

Before you run the Upgrade Assistant to upgrade your schemas and configurations, you must shut down all of the pre-upgrade processes and servers, including the Administration Server and any managed servers.

An Oracle Fusion Middleware environment can consist of an Oracle WebLogic Server domain, an Administration Server, multiple managed servers, Java components, system components such as Identity Management components, and a database used as a repository for metadata. The components may be dependent on each other, so they must be stopped in the correct order.

Note:

The procedures in this section describe how to stop the existing, pre-upgrade servers and processes using the WLST command-line utility or a script. You can also use the Oracle Fusion Middleware Control and the Oracle WebLogic Server Administration Console. See Starting and Stopping Administration and Managed Servers and Node Manager.

To stop your pre-upgrade Fusion Middleware environment, navigate to the pre-upgrade domain and follow the steps below:

Step 1: Stop the Managed Servers

To stop a WebLogic Server Managed Server, use the stopManagedWebLogic script:

(UNIX) EXISTING_DOMAIN_HOME/bin/stopManagedWebLogic.sh managed_server_name admin_url
(Windows) EXISTING_DOMAIN_HOME\bin\stopManagedWebLogic.cmd managed_server_name admin_url

When prompted, enter your user name and password.

Step 2: Stop System Components

To stop system components, such as Oracle HTTP Server, use the stopComponent script:

(UNIX) EXISTING_DOMAIN_HOME/bin/stopComponent.sh component_name
(Windows) EXISTING_DOMAIN_HOME\bin\stopComponent.cmd component_name

You can stop system components in any order.

Step 3: Stop the Administration Server

When you stop the Administration Server, you also stop the processes running in the Administration Server, including the WebLogic Server Administration Console and Fusion Middleware Control.

To stop the Administration Server, use the stopWebLogic script:

(UNIX) EXISTING_DOMAIN_HOME/bin/stopWebLogic.sh
(Windows) EXISTING_DOMAIN_HOME\bin\stopWebLogic.cmd

When prompted, enter your user name, password, and the URL of the Administration Server.

Step 4: Stop Node Manager

To stop Node Manager, close the command shell in which it is running.

Alternatively, after setting the nodemanager.properties attribute QuitEnabled to true (the default is false), you can use WLST to connect to Node Manager and shut it down. See stopNodeManager in Oracle Fusion Middleware WLST Command Reference for WebLogic Server.

Upgrading Product Schemas

After stopping servers and processes, use the Upgrade Assistant to upgrade supported product schemas to the current release of Oracle Fusion Middleware.

The Upgrade Assistant allows you to upgrade individually selected schemas or all schemas associated with a domain. The option you select determines which Upgrade Assistant screens you will use.

Identifying Existing Schemas Available for Upgrade
This optional task enables you to review the list of available schemas before you begin the upgrade by querying the schema version registry. The registry contains schema information such as version number, component name and ID, date of creation and modification, and custom prefix.
Starting the Upgrade Assistant
Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 12c (12.2.1.4.0).
Upgrading Oracle WebCenter Schemas Using the Upgrade Assistant
Navigate through the screens in the Upgrade Assistant to upgrade the product schemas.
Verifying the Schema Upgrade
After completing all the upgrade steps, verify that the upgrade was successful by checking that the schema version in schema_version_registry has been properly updated.

Parent topic: Upgrading an Oracle WebCenter Domain

Identifying Existing Schemas Available for Upgrade

This optional task enables you to review the list of available schemas before you begin the upgrade by querying the schema version registry. The registry contains schema information such as version number, component name and ID, date of creation and modification, and custom prefix.

You can let the Upgrade Assistant upgrade all of the schemas in the domain, or you can select individual schemas to upgrade. To help decide, follow these steps to view a list of all the schemas that are available for an upgrade:

If you are using an Oracle database, connect to the database by using an account that has Oracle DBA privileges, and run the following from SQL*Plus:

SET LINE 120
COLUMN MRC_NAME FORMAT A14
COLUMN COMP_ID FORMAT A20
COLUMN VERSION FORMAT A12
COLUMN STATUS FORMAT A9
COLUMN UPGRADED FORMAT A8
SELECT MRC_NAME, COMP_ID, OWNER, VERSION, STATUS, UPGRADED FROM SCHEMA_VERSION_REGISTRY ORDER BY MRC_NAME, COMP_ID;

Examine the report that is generated.

If an upgrade is not needed for a schema, the schema_version_registry table retains the schema at its pre-upgrade version.
Note the schema prefix name that was used for your existing schemas. You will use the same prefix when you create new 12c (12.2.1.4.0) schemas.

Notes:

If your existing schemas are not from a supported version, then you must upgrade them to a supported version before using the 12c (12.2.1.4.0) upgrade procedures. Refer to your pre-upgrade version documentation for more information.
Some components, such as Oracle Enterprise Data Quality, Oracle GoldenGate Monitor, and Oracle GoldenGate Veridata, support an upgrade from versions other than the standard Oracle Fusion Middleware supported versions.
If you used an OID-based policy store in the earlier versions, make sure to create a new OPSS schema before you perform the upgrade. After the upgrade, the OPSS schema remains an LDAP-based store.
You can only upgrade schemas for products that are available for upgrade in Oracle Fusion Middleware release 12c (12.2.1.4.0). Do not attempt to upgrade a domain that includes components that are not yet available for upgrade to 12c (12.2.1.4.0).

Parent topic: Upgrading Product Schemas

Starting the Upgrade Assistant

Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 12c (12.2.1.4.0).

To start the Upgrade Assistant:

Note:

Before you start the Upgrade Assistant, make sure that the JVM character encoding is set to UTF-8 for the platform on which the Upgrade Assistant is running. If the character encoding is not set to UTF-8, then you will not be able to download files containing Unicode characters in their names. This can cause the upgrade to fail.

Go to the oracle_common/upgrade/bin directory:
- (UNIX) ORACLE_HOME/oracle_common/upgrade/bin
- (Windows) ORACLE_HOME\oracle_common\upgrade\bin
Start the Upgrade Assistant:
- (UNIX) ./ua
- (Windows) ua.bat

For information about other parameters that you can specify on the command line, such as logging parameters, see:

Upgrade Assistant Parameters

Parent topic: Upgrading Product Schemas

Upgrade Assistant Parameters

When you start the Upgrade Assistant from the command line, you can specify additional parameters.

Table 3-7 Upgrade Assistant Command-Line Parameters

Parameter	Required or Optional	Description
`-readiness`	Required for readiness checks Note: Readiness checks cannot be performed on standalone installations (those not managed by the WebLogic Server).	Performs the upgrade readiness check without performing an actual upgrade. Schemas and configurations are checked. Do not use this parameter if you have specified the `-examine` parameter.
`-threads`	Optional	Identifies the number of threads available for concurrent schema upgrades or readiness checks of the schemas. The value must be a positive integer in the range 1 to 8. The default is 4.
`-response`	Required for silent upgrades or silent readiness checks	Runs the Upgrade Assistant using inputs saved to a response file generated from the data that is entered when the Upgrade Assistant is run in GUI mode. Using this parameter runs the Upgrade Assistant in silent mode (without displaying Upgrade Assistant screens).
`-examine`	Optional	Performs the examine phase but does not perform an actual upgrade. Do not specify this parameter if you have specified the `-readiness` parameter.
`-logLevel attribute`	Optional	Sets the logging level, specifying one of the following attributes: `TRACE` `NOTIFICATION` `WARNING` `ERROR` `INCIDENT_ERROR` The default logging level is `NOTIFICATION`. Consider setting the `-logLevel TRACE` attribute to so that more information is logged. This is useful when troubleshooting a failed upgrade. The Upgrade Assistant's log files can become very large if `-logLevel TRACE` is used.
`-logDir location`	Optional	Sets the default location of upgrade log files and temporary files. You must specify an existing, writable directory where the Upgrade Assistant creates log files and temporary files. The default locations are: (UNIX) `ORACLE_HOME/oracle_common/upgrade/logs` `ORACLE_HOME/oracle_common/upgrade/temp` (Windows) `ORACLE_HOME\oracle_common\upgrade\logs` `ORACLE_HOME\oracle_common\upgrade\temp`
`-help`	Optional	Displays all of the command-line options.

Upgrading Oracle WebCenter Schemas Using the Upgrade Assistant

Navigate through the screens in the Upgrade Assistant to upgrade the product schemas.

To upgrade product schemas with the Upgrade Assistant:

On the Welcome screen, review an introduction to the Upgrade Assistant and information about important pre-upgrade tasks. Click Next.

Note:
For more information about any Upgrade Assistant screen, click Help on the screen.
On the Selected Schemas screen, select the schema upgrade operation that you want to perform:
- Individually Selected Schemas if you want to select individual schemas for upgrade and you do not want to upgrade all of the schemas used by the domain.
  
  Caution:
  Upgrade only those schemas that are used to support your 12c (12.2.1.4.0) components. Do not upgrade schemas that are currently being used to support components that are not included in Oracle Fusion Middleware 12c (12.2.1.4.0).
- All Schemas Used by a Domain to allow the Upgrade Assistant to discover and select all components that have a schema available to upgrade in the domain specified in the Domain Directory field. This is also known as a domain assisted schema upgrade. Additionally, the Upgrade Assistant pre-populates connection information on the schema input screens.
  
  Note:
  Oracle recommends that you select All Schemas Used by a Domain for most upgrades to ensure all of the required schemas are included in the upgrade.
Click Next.
If you selected Individually Selected Schemas: On the Available Components screen, select the components for which you want to upgrade schemas. When you select a component, the schemas and any dependencies are automatically selected.
On the Prerequisites screen, acknowledge that the prerequisites have been met by selecting all the check boxes. Click Next.

Note:
The Upgrade Assistant does not verify whether the prerequisites have been met.
On the Schema Credentials screen(s), specify the database connection details for each schema you are upgrading (the screen name changes based on the schema selected):
- Select the database type from the Database Type drop-down menu.
- Enter the database connection details, and click Connect.
- Select the schema you want to upgrade from the Schema User Name drop-down menu, and then enter the password for the schema. Be sure to use the correct schema prefix for the schemas you are upgrading.
  
  Note:
  The component ID or schema name is changed for UCSUMS schema as of release 12.1.2, which means the Upgrade Assistant does not automatically recognize the possible schemas and display them in a drop-down list. You must manually enter the name in a text field. The name can be either prefix_ORASDPM or prefix_UMS, depending on the starting point for the upgrade.
On the Examine screen, review the status of the Upgrade Assistant as it examines each schema, verifying that the schema is ready for upgrade. If the status is Examine finished, click Next.
If the examine phase fails, Oracle recommends that you cancel the upgrade by clicking No in the Examination Failure dialog. Click View Log to see what caused the error and refer to Troubleshooting Your Upgrade in Oracle Fusion Middleware Upgrading with the Upgrade Assistant for information on resolving common upgrade errors.
Note:
- If you resolve any issues detected during the examine phase without proceeding with the upgrade, you can start the Upgrade Assistant again without restoring from backup. However, if you proceed by clicking Yes in the Examination Failure dialog box, you need to restore your pre-upgrade environment from backup before starting the Upgrade Assistant again.
- Canceling the examination process has no effect on the schemas or configuration data; the only consequence is that the information the Upgrade Assistant has collected must be collected again in a future upgrade session.
On the Upgrade Summary screen, review the summary of the schemas that will be upgraded and/or created.
Verify that the correct Source and Target Versions are listed for each schema you intend to upgrade.

If you want to save these options to a response file to run the Upgrade Assistant again later in response (or silent) mode, click Save Response File and provide the location and name of the response file. A silent upgrade performs exactly the same function that the Upgrade Assistant performs, but you do not have to manually enter the data again.

Click Next .
On the Upgrade Progress screen, monitor the status of the upgrade.

Caution:
Allow the Upgrade Assistant enough time to perform the upgrade. Do not cancel the upgrade operation unless absolutely necessary. Doing so may result in an unstable environment.

If any schemas are not upgraded successfully, refer to the Upgrade Assistant log files for more information.

Note:
The progress bar on this screen displays the progress of the current upgrade procedure. It does not indicate the time remaining for the upgrade.

Click Next.
If the upgrade is successful: On the Upgrade Success screen, click Close to complete the upgrade and close the wizard.

If the upgrade fails: On the Upgrade Failure screen, click View Log to view and troubleshoot the errors. The logs are available at NEW_ORACLE_HOME/oracle_common/upgrade/logs.

Note:
If the upgrade fails, you must restore your pre-upgrade environment from backup, fix the issues, then restart the Upgrade Assistant.

Parent topic: Upgrading Product Schemas

Verifying the Schema Upgrade

After completing all the upgrade steps, verify that the upgrade was successful by checking that the schema version in schema_version_registry has been properly updated.

If you are using an Oracle database, connect to the database as a user having Oracle DBA privileges, and run the following from SQL*Plus to get the current version numbers:

SET LINE 120
COLUMN MRC_NAME FORMAT A14
COLUMN COMP_ID FORMAT A20
COLUMN VERSION FORMAT A12
COLUMN STATUS FORMAT A9
COLUMN UPGRADED FORMAT A8
SELECT MRC_NAME, COMP_ID, OWNER, VERSION, STATUS, UPGRADED FROM SCHEMA_VERSION_REGISTRY ORDER BY MRC_NAME, COMP_ID ;

In the query result:

Check that the number in the VERSION column matches the latest version number for that schema. For example, verify that the schema version number is 12.2.1.4.0.

Note:

However, that not all schema versions will be updated. Some schemas do not require an upgrade to this release and will retain their pre-upgrade version number.
The STATUS field will be either UPGRADING or UPGRADED during the schema patching operation, and will become VALID when the operation is completed.
If the status appears as INVALID, the schema update failed. You should examine the logs files to determine the reason for the failure.
Synonym objects owned by IAU_APPEND and IAU_VIEWER will appear as INVALID, but that does not indicate a failure.

They become invalid because the target object changes after the creation of the synonym. The synonyms objects will become valid when they are accessed. You can safely ignore these INVALID objects.

About Reconfiguring the Domain

Run the Reconfiguration Wizard to reconfigure your domain component configurations to 12c (12.2.1.4.0).

Note:

If the source is a clustered environment, run the Reconfiguration Wizard on the primary node only.

When you reconfigure a WebLogic Server domain, the following items are automatically updated, depending on the applications in the domain:

WebLogic Server core infrastructure
Domain version

Note:

Before you begin the domain reconfiguration, note the following limitations:

The Reconfiguration Wizard does not update any of your own applications that are included in the domain.
Transforming a non-dynamic cluster domain to a dynamic cluster domain during the upgrade process is not supported.

The dynamic cluster feature is available when running the Reconfiguration Wizard, but Oracle only supports upgrading a non-dynamic cluster upgrade and then adding dynamic clusters. You cannot add dynamic cluster during the upgrade process.

If the installation that you’re upgrading does not use Oracle Access Management (OAM), then you must edit two files to prevent the Reconfiguration Wizard from attempting to update the nonexistent OAM Infrastructure schema, which causes the upgrade to fail.

Comment out the lines in your $DOMAIN/init-info/domain-info.xml that are similar to this example:

<!--extention-template-ref name="Oracle Identity Navigator" 
  version="11.1.1.3.0" 
  location="/u01/app/oracle/product/fmw/iam111130/common/templates/applications/yourcomany.oinav_11.1.1.3.0_template.jar" 
  symbol=""/-->

<!--install-comp-ref name="oracle.idm.oinav" version="11.1.1.3.0" 
  symbol="yourcompany.idm.oinav_11.1.1.3.0_iam111130_ORACLE_HOME" 
  product_home="/u01/app/oracle/product/fmw/iam111130"/-->

and similarly comment out the lines in $DOMAIN/config/config.xml that are similar to this example:

<!--app-deployment> 
  <name>oinav#11.1.1.3.0</name>
  <target>AdminServer</target>
  <module-type>ear</module-type>

  <source-path>/u01/app/oracle/product/fmw/iam111130/oinav/modules/oinav.ear_11.1.1.3.0/oinav.ear</source-path>
  <deployment-order>500</deployment-order>
  <security-dd-model>DDOnly</security-dd-model>
  <staging-mode>nostage</staging-mode>
</app-deployment-->

Specifically, when you reconfigure a domain, the following occurs:

The domain version number in the config.xml file for the domain is updated to the Administration Server's installed WebLogic Server version.
Reconfiguration templates for all installed Oracle products are automatically selected and applied to the domain. These templates define any reconfiguration tasks that are required to make the WebLogic domain compatible with the current WebLogic Server version.
Start scripts are updated.

If you want to preserve your modified start scripts, be sure to back them up before starting the Reconfiguration Wizard.

Note:

When the domain reconfiguration process starts, you can’t undo the changes that it makes. Before running the Reconfiguration Wizard, ensure that you have backed up the domain as covered in the pre-upgrade checklist. If an error or other interruption occurs while running the Reconfiguration Wizard, you must restore the domain by copying the files and directories from the backup location to the original domain directory. This is the only way to ensure that the domain has been returned to its original state before reconfiguration.

Follow these instructions to reconfigure the existing domain using the Reconfiguration Wizard. See Reconfiguring WebLogic Domains in Oracle Fusion Middleware Upgrading Oracle WebLogic Server.

Backing Up the Domain
Starting the Reconfiguration Wizard
Reconfiguring the Domain with the Reconfiguration Wizard
Navigate through the screens in the Reconfiguration Wizard to reconfigure your existing domain.

Parent topic: Upgrading an Oracle WebCenter Domain

Backing Up the Domain

Before running the Reconfiguration Wizard, create a backup copy of the domain directory.

To create a backup of the domain directory:

Copy the source domain to a separate location to preserve the contents.
(Windows) copy C:\domains\mydomain to C:\domains\mydomain_backup.

(UNIX) cp mydomain /domains/mydomain_backup
Before updating the domain on each remote Managed Server, create a backup copy of the domain directory on each remote machine.
Verify that the backed up versions of the domain are complete.

If domain reconfiguration fails for any reason, you must copy all files and directories from the backup directory into the original domain directory to ensure that the domain is returned entirely to its original state before reconfiguration.

Parent topic: About Reconfiguring the Domain

Starting the Reconfiguration Wizard

Note:

Shut down the administration server and all collocated managed servers before starting the reconfiguration process. See Stopping Servers and Processes.

To start the Reconfiguration Wizard in graphical mode:

Sign in to the system on which the domain resides.
Open the command shell (on UNIX operating systems) or open a command prompt window (on Windows operating systems).
Edition Based Database Users Only: If your schemas are configured with EBR database, a default edition name must be manually supplied before you run the Reconfiguration Wizard.
Run the following SQL command to set the default edition:
ALTER DATABASE DEFAULT EDITION = edition_name;

where edition_name is the child edition name.
Go to the oracle_common/common/bin directory:
- (UNIX) NEW_ORACLE_HOME/oracle_common/common/bin
- (Windows) NEW_ORACLE_HOME\oracle_common\commom\bin
Start the Reconfiguration Wizard with the following logging options:
- (UNIX) ./reconfig.sh -log=log_file -log_priority=ALL
- (Windows) reconfig.cmd -log=log_file -log_priority=ALL
where log_file is the absolute path of the log file you'd like to create for the domain reconfiguration session. This can be helpful if you need to troubleshoot the reconfiguration process.
The parameter -log_priority=ALL ensures that logs are logged in fine mode.
Note:

When you run this command, the following error message might appear to indicate that the default cache directory is not valid:
```
*sys-package-mgr*: can't create package cache dir
```
You can change the cache directory by setting the environment variable CONFIG_JVM_ARGS. For example:

CONFIG_JVM_ARGS=-Dpython.cachedir=valid_directory

Parent topic: About Reconfiguring the Domain

Reconfiguring the Domain with the Reconfiguration Wizard

Navigate through the screens in the Reconfiguration Wizard to reconfigure your existing domain.

Note:

If the source is a clustered environment, run the Reconfiguration Wizard on the primary node only. Use the pack/unpack utility to apply the changes to other cluster members in the domain.

To reconfigure the domain with the Reconfiguration Wizard:

On the Select Domain screen, specify the location of the domain you want to upgrade or click Browse to navigate and select the domain directory. Click Next.
On the Reconfiguration Setup Progress screen, view the progress of the setup process. When complete, click Next.
During this process:
- The reconfiguration templates for your installed products, including Fusion Middleware products, are automatically applied. This updates various domain configuration files such as config.xml, config-groups.xml, and security.xml (among others).
- Schemas, scripts, and other such files that support your Fusion Middleware products are updated.
- The domain upgrade is validated.
On the Domain Mode and JDK screen, select the JDK to use in the domain or click Browse to navigate to the JDK you want to use. The supported JDK version for 12c (12.2.1.4.0) is 1.8.0_211 and later. Click Next.

Note:
You cannot change the Domain Mode at this stage.

For a list of JDKs that are supported for a specific platform, see Oracle Fusion Middleware Supported System Configurations.
On the Database Configuration Type screen, select RCU Data to connect to the Server Table (_STB) schema.
Enter the database connection details using the RCU service table (_STB) schema credentials and click Get RCU Configuration.

The Reconfiguration Wizard uses this connection to automatically configure the data sources required for components in your domain.

Note:
By default Oracle’s Driver (Thin) for Service connections; Versions: Any is the selected driver. If you specified an instance name in your connection details — instead of the service name — you must select Oracle’s Driver (Thin) for pooled instance connections; Versions: Any If you do not change the driver type, then the connection will fail.

Note:
For any existing 12c (12.2.1.3.0) datasource, the reconfiguration will preserve the existing values. For new datasources where the schema was created for 12c (12.2.1.4.0) by the RCU, the default connection data will be retrieved from the _STB schema. If no connection data for a given schema is found in the _STB schema, then the default connection data is used.

If the check is successful, click Next. If the check fails, reenter the connection details correctly and try again.
On the JDBC Component Schema screen, verify that the DBMS/Service and the Host name is correct for each component schema and click Next.
On the JDBC Component Schema Test screen, select all the component schemas and click Test Selected Connections to test the connection for each schema. The result of the test is indicated in the Status column.
When the check is complete, click Next.
On the Advanced Configuration screen, you can select all categories for which you want to perform advanced configuration. For each category you select, the appropriate configuration screen is displayed to allow you to perform advanced configuration.

Note:
The categories that are listed on the Advanced Configuration screen depend on the resources defined in the templates you selected for the domain.

Upgrade Assistant Parameters

When you start the Upgrade Assistant from the command line, you can specify additional parameters.

Table 3-8 Upgrade Assistant Command-Line Parameters

Parameter	Required or Optional	Description
`-readiness`	Required for readiness checks Note: Readiness checks cannot be performed on standalone installations (those not managed by the WebLogic Server).	Performs the upgrade readiness check without performing an actual upgrade. Schemas and configurations are checked. Do not use this parameter if you have specified the `-examine` parameter.
`-threads`	Optional	Identifies the number of threads available for concurrent schema upgrades or readiness checks of the schemas. The value must be a positive integer in the range 1 to 8. The default is 4.
`-response`	Required for silent upgrades or silent readiness checks	Runs the Upgrade Assistant using inputs saved to a response file generated from the data that is entered when the Upgrade Assistant is run in GUI mode. Using this parameter runs the Upgrade Assistant in silent mode (without displaying Upgrade Assistant screens).
`-examine`	Optional	Performs the examine phase but does not perform an actual upgrade. Do not specify this parameter if you have specified the `-readiness` parameter.
`-logLevel attribute`	Optional	Sets the logging level, specifying one of the following attributes: `TRACE` `NOTIFICATION` `WARNING` `ERROR` `INCIDENT_ERROR` The default logging level is `NOTIFICATION`. Consider setting the `-logLevel TRACE` attribute to so that more information is logged. This is useful when troubleshooting a failed upgrade. The Upgrade Assistant's log files can become very large if `-logLevel TRACE` is used.
`-logDir location`	Optional	Sets the default location of upgrade log files and temporary files. You must specify an existing, writable directory where the Upgrade Assistant creates log files and temporary files. The default locations are: (UNIX) `ORACLE_HOME/oracle_common/upgrade/logs` `ORACLE_HOME/oracle_common/upgrade/temp` (Windows) `ORACLE_HOME\oracle_common\upgrade\logs` `ORACLE_HOME\oracle_common\upgrade\temp`
`-help`	Optional	Displays all of the command-line options.

Upgrading Domain Component Configurations Using the Upgrade Assistant

Navigate through the screens in the Upgrade Assistant to upgrade component configurations in the WebLogic domain.

After running the Reconfiguration Wizard to reconfigure the WebLogic domain to 12c (12.2.1.4.0), you must run the Upgrade Assistant to upgrade the domain component configurations to match the updated domain configuration.

To upgrade domain component configurations with the Upgrade Assistant:

On the Welcome screen, review an introduction to the Upgrade Assistant and information about important pre-upgrade tasks. Click Next.

Note:
For more information about any Upgrade Assistant screen, click Help on the screen.
On the next screen:
- Select All Configurations Used By a Domain. The screen name changes to WebLogic Components.
- In the Domain Directory field, enter the WebLogic domain directory path.
Click Next.
On the Component List screen, verify that the list includes all the components for which you want to upgrade configurations and click Next.
If you do not see the components you want to upgrade, click Back to go to the previous screen and specify a different domain.
On the Prerequisites screen, acknowledge that the prerequisites have been met by selecting all the check boxes. Click Next.

Note:
The Upgrade Assistant does not verify whether the prerequisites have been met.
On the Examine screen, review the status of the Upgrade Assistant as it examines each component, verifying that the component configuration is ready for upgrade. If the status is Examine finished, click Next.
If the examine phase fails, Oracle recommends that you cancel the upgrade by clicking No in the Examination Failure dialog. Click View Log to see what caused the error and refer to Troubleshooting Your Upgrade in Oracle Fusion Middleware Upgrading with the Upgrade Assistant for information on resolving common upgrade errors.
Note:
- If you resolve any issues detected during the examine phase without proceeding with the upgrade, you can start the Upgrade Assistant again without restoring from backup. However, if you proceed by clicking Yes in the Examination Failure dialog box, you need to restore your pre-upgrade environment from backup before starting the Upgrade Assistant again.
- Canceling the examination process has no effect on the configuration data; the only consequence is that the information the Upgrade Assistant has collected must be collected again in a future upgrade session.
On the Upgrade Summary screen, review the summary of the options you have selected for component configuration upgrade.
The response file collects and stores all the information that you have entered, and enables you to perform a silent upgrade at a later time. The silent upgrade performs exactly the same function that the Upgrade Assistant performs, but you do not have to manually enter the data again. If you want to save these options to a response file, click Save Response File and provide the location and name of the response file.

Click Upgrade to start the upgrade process.
On the Upgrade Progress screen, monitor the status of the upgrade.

Caution:
Allow the Upgrade Assistant enough time to perform the upgrade. Do not cancel the upgrade operation unless absolutely necessary. Doing so may result in an unstable environment.

If any components are not upgraded successfully, refer to the Upgrade Assistant log files for more information.

Note:
The progress bar on this screen displays the progress of the current upgrade procedure. It does not indicate the time remaining for the upgrade.

Click Next.
If the upgrade is successful: On the Upgrade Success screen, click Close to complete the upgrade and close the wizard. The Post-Upgrade Actions window describes the manual tasks you must perform to make components functional in the new installation. This window appears only if a component has post-upgrade steps.

If the upgrade fails: On the Upgrade Failure screen, click View Log to view and troubleshoot the errors. The logs are available at ORACLE_HOME/oracle_common/upgrade/logs.

Note:
If the upgrade fails you must restore your pre-upgrade environment from backup, fix the issues, then restart the Upgrade Assistant.

Verifying the Domain-Specific-Component Configurations Upgrade

To verify that the domain-specific-component configurations upgrade was successful, sign in to the Administration console and the Oracle Enterprise Manager Fusion Middleware Control and verify that the version numbers for each component is 12.2.1.4.0.

To sign in to the Administration Console, go to: http://administration_server_host:administration_server_port/console

To sign in to Oracle Enterprise Manager Fusion Middleware Control Console, go to: http://administration_server_host:administration_server_port/em

Note:

After upgrade, make sure you run the administration tools from the new 12c (12.2.1.4.0) Oracle home directory and not from the previous Oracle home directory.

During the upgrade process, some OWSM documents, including policy sets and predefined documents such as policies and assertion templates, may need to be upgraded. If a policy set or a predefined document is upgraded, its version number is incremented by 1.

If you created the FMW user to run the Upgrade Assistant, ensure that you delete the account after verifying your upgrade was successful.

Parent topic: Upgrading an Oracle WebCenter Domain

Starting Servers and Processes

After a successful upgrade, restart all processes and servers, including the Administration Server and any Managed Servers.

The components may be dependent on each other so they must be started in the correct order.

Note:

The procedures in this section describe how to start servers and process using the WLST command line or a script. You can also use the Oracle Fusion Middleware Control and the Oracle WebLogic Server Administration Console. See Starting and Stopping Administration and Managed Servers and Node Manager in Administering Oracle Fusion Middleware.

To start your Fusion Middleware environment, follow the steps below:

Step 1: Start the Administration Server

When you start the Administration Server, you also start the processes running in the Administration Server, including the WebLogic Server Administration Console and Fusion Middleware Control.

To start the Administration Server, use the startWebLogic script:

(UNIX) NEW_DOMAIN_HOME/bin/startWebLogic.sh
(Windows) NEW_DOMAIN_HOME\bin\startWebLogic.cmd

When prompted, enter your user name, password, and the URL of the Administration Server.

Step 2: Start Node Manager

To start Node Manager, use the startNodeManager script:

(UNIX) NEW_DOMAIN_HOME/bin/startNodeManager.sh
(Windows) NEW_DOMAIN_HOME\bin\startNodeManager.cmd

Step 3: Start the Managed Servers

To start a WebLogic Server Managed Server, use the startManagedWebLogic script:

(UNIX) NEW_DOMAIN_HOME/bin/startManagedWebLogic.sh managed_server_name admin_url
(Windows) NEW_DOMAIN_HOME\bin\startManagedWebLogic.cmd managed_server_name admin_url

When prompted, enter your user name and password.

Note:

The startup of a Managed Server will typically start the applications that are deployed to it. Therefore, it should not be necessary to manually start applications after the Managed Server startup.

Step 4: Start System Components

To start system components, such as Oracle HTTP Server, use the startComponent script:

(UNIX) NEW_DOMAIN_HOME/bin/startComponent.sh component_name
(Windows) NEW_DOMAIN_HOME\bin\startComponent.cmd component_name

You can start system components in any order.

Parent topic: Performing Post-Upgrade Configuration Tasks

Synchronizing Keystores

If SSL was configured in your pre-upgrade environment, you must synchronize the keystores from the OPSS security store to your local repository.

To synchronize your keystores, first open a WLST session in offline mode:

cd /ORACLE_HOME/oracle_common/common/bin/
./wlst.sh

Next, from the WSLT command prompt (wls:/offline>), execute the following commands to sync your keystore:

connect('username', 'password','t3://host:port')
svc = getOpssService(name='KeyStoreService')
svc.listKeyStoreAliases(appStripe="system",name="keystoreName",password='',type="*")
syncKeyStores(appStripe='system',keystoreFormat='KSS')

Substitute username, password, host, and port with the appropriate values for your system (the default values are localhost and 7001). Enter your keystore's name for keystoreName.

After you have run the above commands, restart the managed servers.
