4 Upgrading a Managed Oracle HTTP Server from 11g to 12c

This chapter describes the procedure to upgrade a managed Oracle HTTP Server from 11g to 12c. The valid starting points for this upgrade are 11g releases 11.1.1.7 and above.

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

• About the Managed Oracle HTTP Server Upgrade Process from 11g to 12c
  Review the flowchart and roadmap for an overview of the upgrade process for Managed Oracle HTTP Server.
• Installing the Product Distributions
  Before you begin your upgrade, download Oracle Fusion Middleware Infrastructure and Oracle HTTP Server 12c (12.2.1.3.0) distributions on the target system and install them using Oracle Universal Installer.
• Running a Pre-Upgrade Readiness Check
  To identify potential issues with the upgrade, Oracle recommends that you run a readiness check before you start the upgrade process. Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success.
• Stopping Servers and Processes
  Before you run the Upgrade Assistant to upgrade your schemas and configurations, you must shut down all of the pre-upgrade processes and servers, including the Administration Server and any managed servers.
• Creating the Required 12c Schemas with the RCU
  When upgrading, you must create the required schemas. You can use the Repository Creation Utility (RCU) to create customized schemas or, optionally, you can use the Upgrade Assistant to create schemas using the default schema settings. This procedure describes how to create schemas using the RCU. Information about using the Upgrade Assistant to create schemas is covered in the upgrade procedures.
• About Reconfiguring the Domain
  Run the Reconfiguration Wizard to reconfigure your domain component configurations to 12c (12.2.1.3.0).
• 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.
• Verifying the Upgrade
  If you can log in to the Administration Console, the Enterprise Manager Fusion Middleware Control, and the OHS Home Page, then your upgrade is successful.
• Importing Wallets to the KSS Database after an Upgrade Using WLST
  When you use Upgrade Assistant to upgrade from a previous version of Oracle HTTP Server to 12c (12.2.1.3.0), you must perform an additional wallet management task.

Installing the Product Distributions

Before you begin your upgrade, download Oracle Fusion Middleware Infrastructure and Oracle HTTP Server 12c (12.2.1.3.0) distributions on the target system and install them using Oracle Universal Installer.

Note:

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

To install the 12c (12.2.1.3.0) distributions:

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 Fusion Middleware Infrastructure (fmw_12.2.1.3.0_infrastructure_generic.jar)
   • Oracle HTTP Server (UNIX: fmw_12.2.1.2.0_ohs_linux64.bin), (Windows: setup_fmw_12.2.1.2.0_ohs_win64.exe)
3. Check that your machines meet the following requirements:
   • Ensure that the system, patch, kernel, and other requirements are met as specified in Installing and Configuring Oracle HTTP Server.
   • Because Oracle HTTP Server is installed by default on port 7777, you must ensure that port 7777 is not used by any service on the nodes. To check if this port is in use, run the following command before you install Oracle HTTP Server. You must free the port if it is in use.

     netstat -an | grep 7777

4. On UNIX platforms, if the /etc/oraInst.loc file exists, check that its contents are correct. Specifically, check that the inventory directory is correct and that you have write permissions for that directory.
   If the /etc/oraInst.loc file does not exist, you can skip this step.
5. Change to the directory where you downloaded the 12c (12.2.1.3.0) product distribution.
6. Start the installation program for Oracle Fusion Middleware Infrastructure:
   • (UNIX) JDK_HOME/bin/java -jar fmw_12.2.1.3.0_infrastructure_generic.jar
   • (Windows) JDK_HOME\bin\java -jar fmw_12.2.1.3.0_infrastructure_generic.jar
7. 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.
8. On the Welcome screen, review the information to make sure that you have met all the prerequisites. Click Next.
9. 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.
10. On the Installation Location screen, specify the location for the Oracle home directory and click Next.
    Since you are installing the standard installation topology for a collocated Oracle HTTP Server in a WebLogic Server domain, enter the path to an existing Oracle Fusion Middleware Infrastructure Oracle home.
    See Selecting Directories for Installation and Configuration in Planning an Installation of Oracle Fusion Middleware.
11. On the Installation Type screen, select the following:
    • For Infrastructure, select Fusion Middleware Infrastructure
    • For Oracle HTTP Server, select Collocated HTTP Server (Managed through WebLogic Server)
    Click Next.
12. 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).
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.
16. After you have installed Oracle Fusion Middleware Infrastructure, enter the following command to start the installer for your product distribution and repeat the steps above to navigate through the installer screens:
    (UNIX) ./fmw_12.2.1.2.0_ohs_linux64.bin
    (Windows) setup_fmw_12.2.1.2.0_ohs_win64.exe

You have installed the Oracle HTTP Server in a collocated mode.

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 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, 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 (12.2.1.3.0) by using the RCU.

Stopping Servers and Processes

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

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

Note:

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

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

Step 1: Stop 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 the Managed Servers

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

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

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

When prompted, enter your user name and password.

Step 3: Stop Oracle Identity Management Components

Stop any Oracle Identity Management components, such as Oracle Internet Directory:

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

• (Windows) EXISTING_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) EXISTING_DOMAIN_HOME/bin/stopWebLogic.sh

• (Windows) EXISTING_DOMAIN_HOME\bin\stopWebLogic.cmd

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

Step 5: 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 WebLogic Server.

Creating the Required 12c Schemas with the RCU

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

Note:

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

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

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

  Note:

  If the Service Table schema does not exist, you may encounter the error message UPGAST-00328 : The schema version registry table does not exist on this database. If that happens it is necessary to create the service table schema in order to run Upgrade Assistant

• Oracle Platform Security Services (OPSS) schema (prefix_OPSS). This schema is required if you are using an OID-based security store in 12c. This schema is automatically created when you run the Repository Creation Utility (RCU). The only supported LDAP-based OPSS security store is Oracle Internet Directory (OID). An LDAP-based policy store is typically used in production environments. You do not need to reassociate an OID-based security store before upgrade. While the Upgrade Assistant is running, you can select the OPSS schema. The Upgrade Assistant upgrades the OID-based security store automatically.

  Note:

  The 12c OPSS database schema is required so that you can reference the 12c schema during the reconfiguration of the domain. Your domain continues to use the OID-based security store after the upgrade is complete.

To create the schemas with the RCU:

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

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

2. Verify that a certified JDK already exists on your system by running java -version from the command line. For 12c (12.2.1.3.0), the certified JDK is 1.8.0_131 and later.
   Ensure that the JAVA_HOME environment variable is set to the location of the certified JDK. For example:
   • (UNIX) setenv JAVA_HOME=/home/Oracle/Java/jdk1.8.0_131
   • (Windows) set JAVA_HOME=C:\home\Oracle\Java\jdk1.8.0_131
   Add $JAVA_HOME/bin to $PATH.
3. Go to the oracle_common/bin directory:
   • (UNIX) NEW_ORACLE_HOME/oracle_common/bin
   • (Windows) NEW_ORACLE_HOME\oracle_common\bin
4. Start the RCU:
   • (UNIX) ./rcu
   • (Windows) rcu.bat
5. On the Welcome screen, click Next.
6. On the Create Repository screen, select Create Repository and then select System Load and Product Load.
   If you do not have DBA privileges, select Prepare Scripts for System Load. This will generate a SQL script containing all the same SQL statements and blocks that would have been called if the RCU were to execute the actions for the selected components. After the script is generated, a user with the necessary SYS or SYSDBA privileges can execute the script to complete the system load phase.

   Click Next.

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

About Reconfiguring the Domain

Run the Reconfiguration Wizard to reconfigure your domain component configurations to 12c (12.2.1.3.0).

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

• WebLogic Server core infrastructure

• Domain version

Note:

The Reconfiguration Wizard does not update any of your own applications that are included in the domain.

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 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.

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
  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. 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 Domain with the Reconfiguration Wizard

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

To reconfigure the domain:

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 (12.2.1.3.0) is 1.8.0_131 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 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.
5. 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.
6. On the Database Configuration Type screen, select RCU Data to connect to the Server Table (_STB) schema.
   Enter the database connection details using the RCU service table (_STB) schema credentials and click Get RCU Configuration.
   The Reconfiguration Wizard uses this connection to automatically configure the data sources required for components in your domain.

   Note:

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

   Note:

   For any existing 12c (12.2.1.2.0) datasource, the reconfiguration will preserve the existing values. For new datasources where the schema was created for 12c (12.2.1.3.0) by the RCU, the default connection data will be retrieved from the _STB schema. If no connection data for a given schema is found in the _STB schema, then the default connection data is used.
   If the check is successful, click Next. If the check fails, reenter the connection details correctly and try again.

   Note:

   If you are upgrading from 12c (12.2.1.2.0), and your database has _OPSS or _IAU 12c (12.2.1.2.0) database schemas, you must manually enter database connection details for those schemas. These schemas were not required in 12c 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.
7. 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.
8. 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 4-8 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.

9. 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.
10. 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.
11. 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.
12. 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.

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 (12.2.1.3.0).
• Upgrading Domain Components Using the Upgrade Assistant
  Navigate through the screens in the Upgrade Assistant to upgrade component configurations in the WebLogic domain.
• Verifying the Domain-Specific-Component Configurations Upgrade
  To verify that the domain-specific-component configurations upgrade was successful, sign in to the Administration console and the Oracle Enterprise Manager Fusion Middleware Control and verify that the version numbers for each component is 12.2.1.3.0.

Starting the Upgrade Assistant

Run the Upgrade Assistant to upgrade product schemas, domain component configurations, or standalone system components to 12c (12.2.1.3.0).

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.

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
   • (Windows) ua.bat

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

• Upgrade Assistant Parameters
  

Upgrade Assistant Parameters

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

Table 4-9 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 Domain Components Using the Upgrade Assistant

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

After running the Reconfiguration Wizard to reconfigure the WebLogic domain to 12c (12.2.1.3.0), you must run the Upgrade Assistant to upgrade the domain component configurations to match the updated domain configuration.

To upgrade domain component configurations with the Upgrade Assistant:

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 WebLogic Components screen, select the WebLogic Component Configurations option to upgrade component configurations for a managed WebLogic Server domain. Enter the connection details required to connect to the WebLogic Administration Server that is managing the domain and 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 Examine screen, review the status of the Upgrade Assistant as it examines each component, verifying that the component configuration is ready for upgrade. If the status is Examine finished, click Next.
   If the examine phase fails, Oracle recommends that you cancel the upgrade by clicking No in the Examination Failure dialog. Click View Log to see what caused the error and refer to Troubleshooting Your Upgrade in Upgrading with the Upgrade Assistant for information on resolving common upgrade errors.

   Note:

   • If you resolve any issues detected during the examine phase without proceeding with the upgrade, you can start the Upgrade Assistant again without restoring from backup. However, if you proceed by clicking Yes in the Examination Failure dialog box, you need to restore your pre-upgrade environment from backup before starting the Upgrade Assistant again.

   • Canceling the examination process has no effect on the configuration data; the only consequence is that the information the Upgrade Assistant has collected must be collected again in a future upgrade session.

6. 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.
7. 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.

8. If the upgrade is successful: On the Upgrade Success screen, click Close to complete the upgrade and close the wizard. The Post-Upgrade Actions window describes the manual tasks you must perform to make components functional in the new installation. This window appears only if a component has post-upgrade steps.
   If the upgrade fails: On the Upgrade Failure screen, click View Log to view and troubleshoot the errors. The logs are available at NEW_ORACLE_HOME/oracle_common/upgrade/logs.

   Note:

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

Verifying the Domain-Specific-Component Configurations Upgrade

To verify that the domain-specific-component configurations upgrade was successful, sign in to the Administration console and the Oracle Enterprise Manager Fusion Middleware Control and verify that the version numbers for each component is 12.2.1.3.0.

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

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

Note:

After upgrade, make sure you run the administration tools from the new 12c (12.2.1.3.0) Oracle home directory and not from the previous Oracle home directory.

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

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

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.

• Starting the Oracle HTTP Server
  You can use Enterprise Manager Fusion Middleware Control to start, stop, and restart Oracle HTTP Server.

Starting the Oracle HTTP Server

You can use Enterprise Manager Fusion Middleware Control to start, stop, and restart Oracle HTTP Server.

You can start the Oracle HTTP Server with the Node Manager by following the procedure mentioned in Running Oracle HTTP Server Remotely in Administering Oracle HTTP Server.

To start an Oracle HTTP Server using Enterprise Manager Fusion Middleware Control:

1. Go to the Oracle HTTP Server home page.
2. From the Oracle HTTP Server menu:
   1. Select Control.
   2. Select Start Up from the Control menu.
   Or
3. From the Target Navigation tree:
   1. Right-click the Oracle HTTP Server instance you want to start.
   2. Select Control.
   3. Select Start Up from the Control menu.

Verifying the Upgrade

If you can log in to the Administration Console, the Enterprise Manager Fusion Middleware Control, and the OHS Home Page, then your upgrade is successful.

To verify the upgrade:

1. Access the OHS default home page by using the following URL:
   http://MachineName:7777
2. Access Enterprise Manager Fusion Middleware Control by using the following URL:
   http://MachineName:7001/em

Importing Wallets to the KSS Database after an Upgrade Using WLST

When you use Upgrade Assistant to upgrade from a previous version of Oracle HTTP Server to 12c (12.2.1.3.0), you must perform an additional wallet management task.

Use the ohs_postUpgrade command to import the wallets for Oracle HTTP Server instances to the KSS database.

This command parses across all of the Oracle HTTP Server instances in the domain and imports the wallets to the KSS database if an entry does not already exist in the database against the same keystore name. See ohs_postUpgrade.

1. Start WLST from the command line.

   (UNIX) ORACLE_HOME/oracle_common/common/bin/wlst.sh

   (Windows) ORACLE_HOME\oracle_common\common\/bin\wlst.cmd

2. Connect to the Administration Server instance:
   connect('<userName', '<password>', '<host>:<port>')
3. Enter the ohs_postUpgrade WLST custom command, for example:
   ohs_postUpgrade()
