7.3 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 if you need to take any action for a successful upgrade.

7.3.1 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 checks during off-peak hours.

7.3.2 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) ORACLE_HOME/oracle_common/upgrade/bin
   • (Windows) 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 Command-Line Parameters
  

7.3.2.1 Upgrade Assistant Command-Line Parameters

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

Table 7-2 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 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 will create 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.

7.3.3 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 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.

     CAUTION

     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 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 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.

7.3.4 Understanding the Readiness Report

After performing a readiness check for your domain, review the report to determine if 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 7-3 Readiness Report Elements

Report Information	Description	Required Action
Overall Readiness Status: SUCCESS or FAILURE	The top of the report indicates whether the Upgrade readiness check passed or completed with one or more errors.	If the report completed with one or more errors, search for FAIL and correct the failing issues before attempting to upgrade. You can re-run the readiness check as many times as necessary before an upgrade.
Timestamp	The date and time that the report was generated.	No action required.
Log file location ORACLE_HOME/oracle_common/upgrade/logs	The directory location of the generated log file.	No action required.
Readiness report location 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, then 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, then 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, then 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 or 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.

7.4 Stopping Servers and Processes

Before running the Upgrade Assistant to upgrade your schemas and configurations, you must shut down all processes and servers, including the Administration server and any managed servers.

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

Note:

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

To stop your Fusion Middleware environment, follow the steps below.

Step 1: Stop System Components

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

• (UNIX) DOMAIN_HOME/bin/stopComponent.sh component_name

• (Windows) DOMAIN_HOME\bin\stopComponent.cmd component_name

You can stop system components in any order.

Step 2: Stop the Managed Servers

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

• (UNIX) DOMAIN_HOME/bin/stopManagedWebLogic.sh managed_server_name admin_url

• (Windows) DOMAIN_HOME\bin\stopManagedWebLogic.cmd managed_server_name admin_url

When prompted, enter your user name and password.

Step 3: Stop Oracle Identity Management Components

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

• (UNIX) DOMAIN_HOME/bin/stopComponent.sh component_name

• (Windows) DOMAIN_HOME\bin\stopComponent.cmd component_name

Step 4: Stop the Administration Server

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

To stop the Administration Server, use the stopWebLogic script:

• (UNIX) DOMAIN_HOME/bin/stopWebLogic.sh

• (Windows) DOMAIN_HOME\bin\stopWebLogic.cmd

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

Note:

If external password storage is set up for the repository, then the server hosting the credential store should be up and running so that the work repository password can be retrieved during upgrade. For more information, see Setting Up External Password Storage in Oracle Fusion Middleware Administering Oracle Data Integrator.

Step 5: Stop Node Manager

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

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

7.5 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 (12.2.1.2). Oracle recommends that you run the Upgrade Assistant as a non-SYSDBA user, completing the upgrade for one domain at a time.
• Upgrading Product 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.

7.5.1 Starting the Upgrade Assistant

Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 12c (12.2.1.2). Oracle recommends that you run the Upgrade Assistant as a non-SYSDBA user, completing the upgrade for one domain at a time.

To start the Upgrade Assistant:

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 Command-Line Parameters
  

7.5.1.1 Upgrade Assistant Command-Line Parameters

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

Table 7-4 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.

7.5.2 Upgrading Product Schemas Using the Upgrade Assistant

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

Notes

• If you are using external authentication, make sure that external authentication is changed to internal authentication.

• Edition-based redefinition (EBR) Users Only: Before upgrading an Edition-Based Redefinition (EBR) enabled schema, you must connect to the database server and create an edition on the database server for 12c. The new edition for 12c must be a child of your existing 12c edition. For more information on creating an edition on the server for redefinition, see Creating an Edition on the Server for Editions-Based Redefinition.

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 Individually Selected Schemas.

   Caution:

   Upgrade only those schemas that are used to support your 12c (12.2.1.2) components. Do not upgrade schemas that are currently being used to support components that are not included in Oracle Fusion Middleware 12c (12.2.1.2).

   Click Next.

3. On the Available Components screen, select Oracle Data Integrator to upgrade the Master and Work Repository schema.
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 ODI Schema screen, specify the database connection details for each schema you are upgrading:

   • 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.

6. On the ODI Options screen, select all of the options.

   Table 7-5 ODI Options

   Option	Description
   Replace Knowledge Modules with mandatory updates	This selection replaces standard Knowledge Modules with the newest version. Customizations to Oracle installed Knowledge Modules will be overwritten. But if you copy an installed Knowledge Module and customize the Knowledge Module, the customizations are not lost.
   Upgrade topology and security metadata	This selection replaces topology and security artifacts such as Technologies, Datatypes, Security Profiles and others with the newest version. Customizations of installed objects will be overwritten. If the object is copied and customized, then the customizations are not lost.

   For information on advanced upgrade options, see Advanced Upgrade Options.

7. On the ODI Supervisor screen, enter the Supervisor account credentials for the ODI repository to be upgraded.

   The installed Supervisor account is SUPERVISOR. Check with your ODI administrator for proper Supervisor account name and password, supplied when prompted by the Repository Creation Utility (RCU) when creating the Master and Work repositories for ODI.

   
   Description of the illustration GUID-7CDFA583-C70D-4F84-B6CC-783B36C85619-default.gif

   Note:

   When All Schemas Used by a Domain is selected, the Supervisor credentials for ODI are not pre-populated in the first instance as the domain does not contain them. If there are multiple ODI schemas, the Upgrade Assistant populates the user entry using the first set of credentials.
8. On the Examine screen, review the status of the Upgrade Assistant as it examines each schema, verifying that the schema is ready for upgrade. If the status is Examine finished, click Next.
   If the examine phase fails, Oracle recommends that you cancel the upgrade by clicking No in the Examination Failure dialog. Click View Log to see what caused the error and refer to Troubleshooting Your Upgrade in Oracle Fusion Middleware Upgrading with the Upgrade Assistant Upgrade Guide 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.

9. On the Upgrade Summary screen, review the summary of the options you have selected for schema upgrade.
   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 Upgrade to start the upgrade process.
10. 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.

11. 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 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.

7.5.3 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 12.2.1.2.0 . 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.

7.6 Reconfiguring the Domain

Run the Reconfiguration Wizard to reconfigure your domain component configurations to 12c (12.2.1.2).

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:

Once the domain reconfiguration process starts, it is irreversible. 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. For general information about how the domain is reconfigured, see Reconfiguring WebLogic Domains in Oracle Fusion Middleware Upgrading Oracle WebLogic Server.

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

7.6.1 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.
   For example, copy C:\domains\mydomain to C:\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.

7.6.2 Starting the Reconfiguration Wizard

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) ORACLE_HOME/oracle_common/common/bin
   • (Windows) 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

7.6.3 Reconfiguring the Domain with the Reconfiguration Wizard

Navigate through the screens in the Reconfiguration Wizard to reconfigure your existing domain before running the Upgrade Assistant

Note:

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

   • Schemas, scripts, and other such files that support your Fusion Middleware products 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 12c (12.2.1.2) is 1.8.0_101 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.
4. 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: 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.
5. On the JDBC Component Schema screen, verify that the DBMS/Service and the Host name is correct for each component schema and click Next.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.

7.7 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 the Upgrade Assistant
  Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 12c (12.2.1.2). Oracle recommends that you run the Upgrade Assistant as a non-SYSDBA user, completing the upgrade for one domain at a time.

7.8 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) DOMAIN_HOME/bin/startWebLogic.sh

• (Windows) 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) DOMAIN_HOME/bin/startNodeManager.sh

• (Windows) 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) DOMAIN_HOME/bin/startComponent.sh component_name

• (Windows) 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) DOMAIN_HOME/bin/startManagedWebLogic.sh managed_server_name admin_url

• (Windows) 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) DOMAIN_HOME/bin/startComponent.sh component_name

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

You can start system components in any order.
