Installing the Standalone Oracle HTTP Server

Before you begin your upgrade, download the Oracle HTTP Server 14c (14.1.2.0.0) distribution on the target system and install it by using the Oracle Universal Installer.

To install the standalone Oracle HTTP Server:
  1. Sign in to the target system.
  2. Download the following from Oracle Technology Network or Oracle Software Delivery Cloud to your target system:
    Oracle HTTP Server (UNIX: fmw_14.1.2.0.0_ohs_linux64.bin), (Windows: setup_fmw_14.1.2.0.0_ohs_win64.exe)
  3. Change to the directory where you downloaded the 14c (14.1.2.0.0) product distribution.
  4. Ensure that the system, patch, kernel, and other requirements are met as specified in theRoadmap for Verifying Your System Environment.
  5. Enter the following command to start the installation program:
    (UNIX) ./fmw_14.1.2.0.0_ohs_linux64.bin
    (Windows) setup_fmw_14.1.2.0.0_ohs_win64.exe
  6. 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.
  7. On the Welcome screen, review the information to make sure that you have met all the prerequisites. Click Next.
  8. On the Auto Updates screen, select an option:

    • Skip Auto Updates: If you do not want your system to check for software updates at this time.

    • Select patches from directory: To navigate to a local directory if you downloaded patch files.

    • Search My Oracle Support for Updates: To automatically download software updates if you have a My Oracle Support account. You must enter Oracle Support credentials then click Search. To configure a proxy server for the installer to access My Oracle Support, click Proxy Settings. Click Test Connection to test the connection.

    Click Next.
  9. On the Installation Location screen, specify the location for the Oracle home directory and click Next.
    As you are installing the standard installation topology for Oracle HTTP Server in a standalone domain, you can specify an Oracle home directory of your choice. However, ensure that you install the software in a new Oracle home.
    See Selecting Directories for Installation and Configuration in Planning an Installation of Oracle Fusion Middleware.
  10. On the Installation Type screen, select Standalone HTTP Server (Managed independently of WebLogic server) and click Next.
  11. The Prerequisite Checks screen analyzes the host computer to ensure that the specific operating system prerequisites have been met.
    To view the list of tasks that are verified, select View Successful Tasks. To view log details, select View Log. If any prerequisite check fails, then an error message appears at the bottom of the screen. Fix the error and click Rerun to try again. To ignore the error or the warning message and continue with the installation, click Skip (not recommended).
  12. On the Security Updates screen, indicate how you would like to receive security updates if you already have an Oracle Support account.
    If you do not have an Oracle Support account and you are sure that you want to skip this step, clear the check box and verify your selection in the follow-up dialog box.
  13. On the Installation Summary screen, verify the installation options that you selected.
    If you want to save these options to a response file, click Save Response File and enter the response file location and name. The response file collects and stores all the information that you have entered, and enables you to perform a silent installation (from the command line) at a later time.

    Click Install to begin the installation.

  14. On the Installation Progress screen, when the progress bar displays 100%, click Finish to dismiss the installer, or click Next to see a summary.
  15. The Installation Complete screen displays the Installation Location and the Feature Sets that are installed. Review this information and click Finish to close the installer.
You have installed the Oracle HTTP Server in a standalone mode.

Stopping Standalone System Components

Before you run the Upgrade Assistant to upgrade your schemas and configurations, you must shut down the pre-upgrade environment.

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

Note:

It is important that you stop the following servers in the correct order.

Step 1: 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 2: 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 WLST Command Reference for Oracle WebLogic Server.

About Reconfiguring the Domain

Run the Reconfiguration Wizard to reconfigure your domain component configurations to 14c (14.1.2.0.0).

Note:

The Reconfiguration Wizard does not update any of your own applications that are included in the domain.
When you reconfigure a standalone domain, the following occurs:

  • The domain version number in the config.xml file for the domain is updated to the version of the target Oracle HTTP Server.

  • The reconfiguration template for Oracle HTTP Server is automatically selected and applied to the domain. This template defines any reconfiguration tasks that are required to make the standalone domain compatible with the target Oracle HTTP Server version.

  • The 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.

Backing Up the Domain

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

  1. Create a backup of the domain directory.
  2. Before updating the domain on each remote Managed Server, create a backup copy of the domain directory on each remote machine.
  3. 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.

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:

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

Reconfiguring the Existing Domain with the Reconfiguration Wizard

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

To reconfigure the domain with the Reconfiguration Wizard:

  1. 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.
  2. 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).

    • Scripts and other such files that support Oracle HTTP Server are updated.

    • The domain upgrade is validated.

  3. 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 14c (14.1.2.0.0) is 17.0.12 and later. Click Next.

    Note:

    You cannot change the Domain Mode at this stage. Your domain will retain its pre-upgrade domain mode. If you want to change the domain to secure mode, then after the upgrade see Changing Domain Mode Post Upgrade.
    For a list of JDKs that are supported for a specific platform, see Oracle Fusion Middleware Supported System Configurations.
  4. 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 3-2 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 and the remaining fields cannot be modified. 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 is 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 is 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 and Password Specify the user name and password that you want to use to start Node Manager in the reconfigured domain.
  5. 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.
  6. The Reconfiguration Progress screen displays the progress of the reconfiguration process.
    During this process:

    • Domain information is extracted, saved, and updated.

    • Scripts and other such files that support Oracle HTTP Server are updated.

    When the progress bar shows 100%, click Next.
  7. 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. If the reconfiguration is successful, it displays Domain Configuration 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 for further operations.

Upgrading Standalone System Component Configurations

Use the Upgrade Assistant to upgrade the standalone agent’s component configurations.

Starting the Upgrade Assistant

Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 14c (14.1.2.0.0).

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. To set the character encoding, run the following:

UNIX operating systems:

export UA_PROPERTIES="-Dfile.encoding=UTF-8 ${UA_PROPERTIES}"

Windows operating systems:

set UA_PROPERTIES=-Dfile.encoding=UTF-8 %UA_PROPERTIES%
  1. Go to the oracle_common/upgrade/bin directory:
    • (UNIX) ORACLE_HOME/oracle_common/upgrade/bin
    • (Windows) ORACLE_HOME\oracle_common\upgrade\bin
  2. 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

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

Table 3-3 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 Standalone System Component Configurations Using the Upgrade Assistant

Navigate through the screens in the Upgrade Assistant to upgrade standalone system component configurations.

To upgrade the existing domain using the Upgrade Assistant:
  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 Standalone Components screen, select Standalone System Component Configurations.
    Select Update an Existing Domain and enter the location of the existing domain in the Domain Directory field. You can also click Browse to select the existing domain directory by using the navigation tree. 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. On the Instance Directories screen, select the correct source and click Next.
  6. On the Examine screen, review the status of the Upgrade Assistant as it examines each standalone component, verifying that the standalone 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 Assistantfor 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 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 Upgrade

You can verify that the upgrade is successful if you are able to start the Node Manager and the Standalone Oracle HTTP Server properly.

If you experience post-upgrade issues, you need to troubleshoot the installation and retry the upgrade. See Troubleshooting Oracle HTTP Server in Administrator's Guide for Oracle HTTP Server.

If you are not able to start the newly upgraded environment, a possible cause could be the use of MD5 certificates in your Oracle wallet. To check whether you are using MD5 signatures and how to replace them with SHA-2 certificates, see Replacing Certificate Signed Using MD5 Algorithm with Certificate Signed Using SHA-2 Algorithm .

Starting Node Manager

Use the Node Manager scripts in the new domain home to 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

Starting the Standalone Oracle HTTP Server

After the upgrade, start the standalone Oracle HTTP Server.

To start the standalone Oracle HTTP Server:
  1. Go to the DOMAIN_HOME/bin directory:
    (UNIX) ORACLE_HOME/user_projects/domains/<domain name>/bin
    (WINDOWS) ORACLE_HOME\user_projects\domains\<domain name>\bin
  2. Enter the command to start the standalone server.
    On UNIX operating systems:
    ./startComponent.sh ohs_name
    On Windows operating systems:
    startComponent.cmd ohs_name
