To Add Cluster Support to a Domain

If your domain is not configured to support clustering, and you require to use clustering features of Application Server, add cluster support to the domain. For example, a domain that is running a developer profile is not configured to support clustering. Use the Admin Console Application Server node General tab to upgrade the domain to support clustering.

The implications of adding cluster support to a domain are as follows:

Before You Begin

To enable you to revert the domain to its original configuration if necessary, back up the domain.xml file of the domain.

Because the administration server will support clusters after the upgrade, consider enhancing JVM settings such as heap-size.

  1. Select the Application Server node.
  2. In the General Information page, click Add Cluster Support.
  3. Review the implications of this procedure.
  4. Click OK.

    The Admin Console displays a message that indicates that a restart is required.

  5. Click Stop Instance.

    The Admin Console displays that the application domain has been shutdown.

  6. If the CLI multimode is running (which means that you are running commands from the asadmin prompt), exit asadmin and restart.
  7. Verify that the domain is stopped by using the asadmin list-domains command.
  8. Start the newly upgraded cluster domain by using the asadmin start-domain command.
  9. Launch the Admin Console.

    The common tasks page now includes cluster-related tasks, indicating that the domain now supports clustering features.
