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.

SET LINE 120
COLUMN MRC_NAME FORMAT A14
COLUMN COMP_ID FORMAT A20

SELECT MRC_NAME, COMP_ID, OWNER, VERSION, STATUS, UPGRADED FROM SCHEMA_VERSION_REGISTRY ORDER BY MRC_NAME, COMP_ID ;

1. Sign in to the system on which the domain resides.
2. Open the command shell (on UNIX operating systems) or open a command prompt window (on Windows operating systems).
3. 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.

4. Go to the oracle_common/common/bin directory:
   • (UNIX) NEW_ORACLE_HOME/oracle_common/common/bin
   • (Windows) NEW_ORACLE_HOME\oracle_common\commom\bin
5. 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

The Reconfiguration Wizard reconfigures the domain while retaining the location of the domain. Navigate through the screens in the Reconfiguration Wizard to reconfigure your existing domain.

1. Sign in to the system on which the domain resides.
2. Edition Based Database Users Only: If you have configured your schemas with Edition-Based Reassociation, you must manually supply a default edition name before running the Reconfiguration Wizard.
   To set the default edition, enter the following SQL command:
   ALTER DATABASE DEFAULT EDITION = edition_name;

   Where, edition_name  is the name of the default database edition.

3. 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.
4. 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.

5. 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.
6. On the JDBC Data Sources screen, configure the JDBC data sources defined in your domain source.
   The JDBC data sources associated with the products for which you are creating the domain are listed in the lower half of the screen. A JDBC data source contains a pool of database connections that are created when the data source instance is created, deployed or targeted, or at server startup. Applications look up a data source on the JNDI tree, and then request a connection. When the applications no longer need the connections, they return the connections to the connection pool in the data source.
   From the Data Source Name drop-down list, select the data source(s) for which you want to specify the settings. The values that you specify are displayed in the appropriate columns in the data source list, for the selected data source.
   For Oracle RAC Configuration for data sources, you can select one of the three options:

   • Convert to GridLink
   • Convert to RAC multi data source
   • Don’t convert

   For more information about each option, click Help.

   After specifying the details, click Next.
   If you do not select any data sources on the JDBC Data Sources screen, the following warning displays:
   Missing Driver
   Click Ok to proceed without verification, click Cancel to return to the JDBC Data Sources page.
   In this case, if you click Ok, the data sources are not verified.
7. On the JDBC Data Sources Test screen, select the check box for the data source connection you configured on the JDBC Data Sources screen and click Test Selected Connections to test the data source connection.

   Note:

   To test the database connections, the database to which you are connecting must be running. If you do not want to test the connections at this time, do not select any data sources. Click Next to continue.
8. 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 11g datasource, the reconfiguration will preserve the existing values. For new datasources where the schema was created for 12c 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.

   Note:

   If you are upgrading from 11g, and your database has _OPSS or _IAU 11g database schemas, you must manually enter database connection details for those schemas. These schemas were not required in 11g and had to be created manually. Users could assign any name to these schemas, therefore the Reconfiguration Wizard does not recognize them. When providing connection information for _IAU, use the IAU_APPEND user information.
9. 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.
10. The Node Manager screen is only displayed if the domain you are reconfiguring is currently using a per host Node Manager.
    On the Node Manager screen, select the Node Manager configuration to use for the reconfigured domain. The resulting configuration depends on the combination of options you select for Node Manager Type  and Node Manager Configuration.

    Table 4-5 Field Descriptions for Node Manager Screen

    Option	Description
    Per Domain Default Location	If you select this option, the Node Manager home is redefined to $domain_name/nodemanager and you cannot edit the Node Manager home.
    Per Domain Custom Location	Select this option if you want the per domain Node Manager configuration files to be created in a specific location for this domain. Specify the directory in the Node Manager Home field, or click Browse to use the navigation tree to select the location. The specified directory must be empty. The nodemanager.properties and nodemanager.domains files are created in this directory.
    Node Manager Home	If you selected the Per Domain Custom Location option, click Browse to navigate to the directory location that you want to use to store the per domain Node Manager configuration.
    Manual Node Manager Setup	If you select this option, creation of the Node Manager configuration for the domain is skipped (all remaining fields cannot be modified), and if you want to use Node Manager in the domain, you must manually configure Node Manager as described in Completing the Node Manager Configuration. The reconfigured domain will still use a per host Node Manager configuration. You should also select this option if your existing domain is not configured to use Node Manager and you do not want to use Node Manager in the reconfigured domain. For more information about Node Manager configuration, see Administering Node Manager for Oracle WebLogic Server.
    Node Manager Configuration	Select one of the following two options. These fields are not available if you selected Manual Node Manager Setup.
    Create New Configuration	A per domain Node Manager configuration will be automatically created for the reconfigured domain using default settings in nodemanager.properties. If necessary, you can modify nodemanager.properties after the domain has been successfully reconfigured.
    Migrate Existing Configuration	The existing per host Node Manager configuration will be migrated to a per domain configuration for the reconfigured domain. This does not include environment-specific settings for ListenAddress, ListenPort, StartScriptName, JavaHome, and LogFile.
    Node Manager Home	If you selected the Migrate Existing Configuration option, enter or browse to the Node Manager home directory that you want to migrate to the reconfigured domain.
    Apply Oracle Recommended Defaults	If you selected the Migrate Existing Configuration option, select this check box if you want to use Oracle-recommended defaults in the nodemanager.properties file. Deselect this check box if you want to continue using the settings in the nodemanager.properties file being migrated. Oracle-recommended properties with default values are as follows: LogLimit=0 AuthenticationEnabled=true LogLevel=INFO DomainsFileEnabled=true NativeVersionEnabled=true LogToStderr=true SecureListener=true LogCount=1 StopScriptEnabled=false QuitEnabled=false LogAppend=true StateCheckInterval=500 CrashRecoveryEnabled=false StartScriptEnabled=true LogFormatter=weblogic.nodemanager.server.LogFormatter ListenBacklog=50
    Node Manager Credentials: Username, Password	Specify the username and password that you want to use to start Node Manager in the reconfigured domain.

11. 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.
    For this upgrade, select none of the options and click Next.
12. On the Configuration Summary screen, review the detailed configuration settings of the domain before continuing.
    You can limit the items that are displayed in the right-most panel by selecting a filter option from the View drop-down list.
    To change the configuration, click Back to return to the appropriate screen. To reconfigure the domain, click Reconfig.

    Note:

    The location of the domain does not change when you reconfigure it.
13. The Reconfiguration Progress screen displays the progress of the reconfiguration process.
    During this process:

    • Domain information is extracted, saved, and updated.

    • Schemas, scripts, and other such files that support your Fusion Middleware products are updated.

    When the progress bar shows 100%, click Next.
14. The End of Configuration screen indicates whether the reconfiguration process completed successfully or failed. It also displays the location of the domain that was reconfigured as well as the Administration Server URL (including the listen port). If the reconfiguration is successful, it displays Oracle WebLogic Server Reconfiguration Succeeded.
    If the reconfiguration process did not complete successfully, an error message is displayed indicates the reason. Take appropriate action to resolve the issue. If you cannot resolve the issue, contact My Oracle Support.
    Note the Domain Location and the Admin Server URL for further operations.

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

1. 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.
2. On the All Configurations screen, select All Configurations Used by a Domain and specify your domain location in the Domain Directory field by entering it directly or by clicking Browse to use a navigation tree to select a valid domain directory. Click Next.
3. 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.
4. 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.
5.  If there are remote managed servers hosting User Messaging Services (UMS) configuration files: On the UMS Configuration screen, provide the credentials to these servers so that the Upgrade Assistant can access the configuration files.

   Note:

   You may need to manually copy the UMS configuration files if the Upgrade Assistant is unable to locate them. See Error while Copying User Messaging Service (UMS) Configuration Files.
6. 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 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.

7. 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.
8. 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.

9. 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 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.

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.
