16 Using HA Power Tools

You can configure the Java Object Cache using the HA Power Tools tab in the Oracle WebLogic Server Administration Console.

This chapter contains the following sections:

• Section 16.1, "Enabling HA Power Tools in the Oracle WebLogic Administration Console"

• Section 16.2, "Configuring Java Object Cache for a Cluster Using HA Power Tools"

• Section 16.3, "Configuring Java Object Cache for Managed Servers Using HA Power Tools"

16.1 Enabling HA Power Tools in the Oracle WebLogic Administration Console

To use HA Power Tools, you must enable them using the following procedure:

1. Copy the following two .war files located in the MW_HOME/oracle_common/hapowertools directory to the DOMAIN_HOME/console-ext directory.

   • powertools-core.war

   • powertools-configurejoc.war

2. Restart the Administration Server.

3. After restarting the Administration Server, the HA Power Tools tab appears when you click Domain in the left navigation tree.

16.2 Configuring Java Object Cache for a Cluster Using HA Power Tools

To configure Java Object Cache for a cluster using HA Power Tools:

1. Log in to Oracle WebLogic Server Administration Console, and click Domain in left navigation tree.

2. Click the HA Power Tools tab.

3. Select the Configure JOC for Cluster radio button.

4. Select the cluster name from the drop-down list.

5. Enter the Discover Port.

6. Enter the Hosts (separate host names by comma).

7. Click Configure JOC.

8. Restart the cluster.

9. Verify JOC configuration using the CacheWatcher utility. See Appendix F, "Configuring the Distributed Java Object Cache."

16.3 Configuring Java Object Cache for Managed Servers Using HA Power Tools

To configure Java Object Cache for Managed Servers using HA Power Tools:

1. Log in to Oracle WebLogic Server Administration Console, and click Domain in left navigation tree.

2. Click the HA Power Tools tab

3. Select the Configure JOC for Managed Server(s) radio button.

4. Enter the Managed Server names and Discover Port.

5. Enter the Hosts (separate host names by comma).

6. Click Configure JOC.

7. Restart the cluster.

8. Verify JOC configuration using the Cache Watcher utility. See Appendix F, "Configuring the Distributed Java Object Cache."

Some of the managed servers can be excluded from the JOC configuration by specifying the server names (comma separated) in the Exclude Server section. The Distribution Mode for all the specified servers are set to false.

Use the Disable Distribution Mode option to disable Distribution Mode for all the affected managed servers. This option is applicable for configuring JOC for a cluster as well as for configuring JOC for Managed Servers.
