4 Upgrading Oracle Fusion Middleware Infrastructure from a Previous 12c Release

You can upgrade to Oracle Fusion Middleware Infrastructure 12c (12.2.1.4.0) from a previous 12c release.

Complete the steps in the following topics to perform the upgrade:

• About the Oracle Fusion Middleware Infrastructure Upgrade Process (from a Previous 12c Release)
  Review the flowchart and roadmap for an overview of the upgrade process for Oracle Fusion Middleware Infrastructure from a previous 12c release.
• Installing Oracle Fusion Middleware Infrastructure
  Installing Fusion Middleware Infrastructure creates an Oracle home directory and lays down supporting software to install other Fusion Middleware products.
• 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 running the Upgrade Assistant, shut down all Oracle Fusion Middleware Managed Servers, Administration Servers, and system components (such as OHS) that may be using the schemas or configurations you want to update. Failure to do so may result in an incomplete or failed upgrade.
• 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.
• Starting Servers and Processes
  After a successful upgrade, restart all processes and servers, including the Administration Server and any Managed Servers.
• Using the Upgrade Validation Checklist
  After the upgrade, make sure that you can successfully complete the basic administration tasks, such as verifying whether you are able to start the Node Manager, Administration Server, Webtier, Administration Console, and Enterprise Manager Fusion Middleware Control.
• Reapplying Custom Configuration Settings to setDomainEnv
  To complete the upgrade of your application environment to 12c it might be necessary to reapply any custom configuration settings to startup scripts, such as setDomainEnv. During the upgrade, the scripts are overwritten with new 12c versions. You must manually reapply the custom configuration settings you had made in previous releases.
• Maintaining the Security Status of Older Java EE Web Service Applications
  The introduction of global policy attachment support for Java EE web services and clients in 12c may impact the backwards compatibility of existing Java EE web services and clients (12.1.2 and earlier). If a Java EE web service or client endpoint that depends on the absence of a policy falls within the scope of a global policy attachment, the presence of the globally-attached policy can alter the security behavior of that endpoint.
• Documentation Resources for Managing your Oracle Fusion Middleware 12c Software
  This topic provides a list of common administration tasks you likely want to perform after upgrading to Infrastructure 12c and associated documentation resources.
• If Your Existing Environment is a Clustered Configuration...
  If your existing environment is a clustered configuration, then you must apply the changes to other cluster members in the domain by using the pack and unpack utilities.
• Starting Servers and Processes
  After a successful upgrade, restart all processes and servers, including the Administration Server and any Managed Servers.

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.

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.

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:

1. Go to the oracle_common/upgrade/bin directory:
   • (UNIX) NEW_ORACLE_HOME/oracle_common/upgrade/bin
   • (Windows) NEW_ORACLE_HOME\oracle_common\upgrade\bin
2. 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
  

Upgrade Assistant Parameters

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

Table 4-2 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) NEW_ORACLE_HOME/oracle_common/upgrade/logs NEW_ORACLE_HOME/oracle_common/upgrade/temp (Windows) NEW_ORACLE_HOME\oracle_common\upgrade\logs NEW_ORACLE_HOME\oracle_common\upgrade\temp
-help	Optional	Displays all of the command-line options.

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:

1. On the Welcome screen, review information about the readiness check. Click Next.
2. 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.

3. 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.

   Click Next to start the readiness check.
4. 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.
5. 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.
6. 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 4-3 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 NEW_ORACLE_HOME/oracle_common/upgrade/logs	The directory location of the generated log file.	No action required.
Readiness report location NEW_ORACLE_HOME/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.

Note:

You can ignore the missing index error in the readiness report. This is a known issue. The corresponding missing index is added during the schema upgrade operation. This error does not occur if the schema to be upgraded was created in 12c using the RCU.

Stopping Servers and Processes

Before running the Upgrade Assistant, shut down all Oracle Fusion Middleware Managed Servers, Administration Servers, and system components (such as OHS) that may be using the schemas or configurations you want to update. Failure to do so may result in an incomplete or failed upgrade.

If you are running the Node Manager, you should also stop the Node Manager. You can do this by closing the console window in which the Node Manager is running, or by using the stopNodeManager WLST command.

For instructions to stop an Oracle Fusion Middleware environment, see Stopping an Oracle Fusion Middleware Environment in Administering Oracle Fusion Middleware.

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.

• 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). Oracle recommends that you run the Upgrade Assistant as a non-SYSDBA user, completing the upgrade for one domain at a time.
• Upgrading 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.

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). Oracle recommends that you run the Upgrade Assistant as a non-SYSDBA user, completing the upgrade for one domain at a time.

Table 4-4 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) NEW_ORACLE_HOME/oracle_common/upgrade/logs NEW_ORACLE_HOME/oracle_common/upgrade/temp (Windows) NEW_ORACLE_HOME\oracle_common\upgrade\logs NEW_ORACLE_HOME\oracle_common\upgrade\temp
-help	Optional	Displays all of the command-line options.

Upgrading 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:

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 Selected Schemas screen, select All Schemas Used by a Domain.
   • 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.

3. If you selected All Schemas Used by a Domain: On the Component List screen you will see two lists of schemas. The first list shows the components whose schemas are present in the domain and will be upgraded. The second list shows the list of missing schemas that may need to be created. If none of the required schemas are missing, you will only see the first list. Review both lists and click Next.
   The Upgrade Assistant will attempt to create any missing schemas using the schema credentials used to create the existing domain schemas. You do not need to launch the Repository Creation Utility.
   If you want to exclude some components or schemas from the list, navigate back to the All Schemas screen and select Individually Selected Schemas. This option allows you to select only those schemas you want included in the upgrade.
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 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 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.
6. 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 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.

7. 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 .
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 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.

9. 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.

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).

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.

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 Upgrading Oracle WebLogic Server.

• Backing Up the Domain
  
• Starting the Reconfiguration Wizard
  
• Reconfiguring the Domain with the Reconfiguration Wizard
  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.

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:

1. 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
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. 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

Reconfiguring the Domain with the Reconfiguration Wizard

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.

Important:

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 as described in If Your Existing Environment is a Clustered Configuration....

To reconfigure the 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.

For all the Advanced Configurations-related screens, such as Managed Servers, Clusters, Machines, HTTP Proxy Applications, Coherence Clusters, and System Components, see Upgrading Oracle WebLogic Server.

If an error occurs while reconfiguring your domain, refer to the Important Notes About the Domain Upgrade Process in Upgrading Oracle WebLogic Server.

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 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.

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 Oracle Identity Management Components

Start any Oracle Identity Management components, such as Oracle Internet Directory, that form part of your environment:

• (UNIX) NEW_DOMAIN_HOME/bin/startComponent.sh component_name

• (Windows) NEW_DOMAIN_HOME\bin\startComponent.cmd component_name

Step 4: 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 5: 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.

Using the Upgrade Validation Checklist

After the upgrade, make sure that you can successfully complete the basic administration tasks, such as verifying whether you are able to start the Node Manager, Administration Server, Webtier, Administration Console, and Enterprise Manager Fusion Middleware Control.

Note:

The order in which you start the following servers is important and failure to start (or stop) them in the correct order can cause issues with the deployment.

1. Verify that you are able to start the Node Managers.
2. Verify that you are able to start the Administration Server and any Managed Servers (if included) from the original Domain Home bin directory. Windows operating system users may find it useful to start the servers from a new command prompt (and not the one used to launch the 12c Upgrade Assistant).

   Note:

   OHS does not need a Managed Server for it's own configuration.
3. Verify that you are able to start the Webtier (OHS server).
4. Verify that you are able to access the Administration console and Enterprise Manager using the following URLs:
   Administration console: http://machinename.my_company_com:administration_port/console
   Enterprise Manager: http://machinename.my_company_com:administration_port/em

Reapplying Custom Configuration Settings to setDomainEnv

To complete the upgrade of your application environment to 12c it might be necessary to reapply any custom configuration settings to startup scripts, such as setDomainEnv. During the upgrade, the scripts are overwritten with new 12c versions. You must manually reapply the custom configuration settings you had made in previous releases.

See Re-apply Customizations to Startup Scripts.

Note:

To prevent losing your custom configuration settings in a future upgrade, see Maintaining Your Custom setDomainEnv Settings.

Maintaining the Security Status of Older Java EE Web Service Applications

The introduction of global policy attachment support for Java EE web services and clients in 12c may impact the backwards compatibility of existing Java EE web services and clients (12.1.2 and earlier). If a Java EE web service or client endpoint that depends on the absence of a policy falls within the scope of a global policy attachment, the presence of the globally-attached policy can alter the security behavior of that endpoint.

Note:

In Fusion Middleware 12.1.2 and earlier, global policy attachments defined for SOAP Web Service and SOAP Web Service Client subject types were applicable to Oracle Infrastructure web services and clients only, and were ignored by Java EE web services and clients. After upgrading to 12c (12.2.1), the global policy attachments defined for these subject types apply to Java EE web services and clients, as well, and may alter the security behavior of existing Java EE web services and clients.

To maintain backwards compatibility, you can disable the global policy attachments for specific endpoints by attaching an OWSM no behavior policy to the service or client, such as no_authentication_service_policy, no_authorization_service_policy, or no_messageprotection_service_policy. See Disabling a Globally Attached Policy in Securing Web Services and Managing Policies with Oracle Web Services Manager.

Note:

You can use the WebLogic Wssp1.5-No-Op.xml no behavior policy. However, since WebLogic security policies can only be attached to web service clients programmatically, it requires code change. See Disabling a Globally Attached Policy in Securing WebLogic Web Services for Oracle WebLogic Server.
