Stop WC_Spaces2 and WC_Portlet2. 6. Access the following URLs and verify the appropriate functionality: ■ WebHost1:7777webcenter ■ WebHost1:7777portalTools

6.4.12 Configuring Manual Failover of the Administration Server to APPHOST2

For information about configuring the Administration Server for high availability, see Section 12.4, Transforming the Administration Server in an Existing Domain for Cold Failover Cluster.

6.4.13 Configuring the Java Object Cache

The Java Object Cache JOC should be configured among all the servers running WebCenter Spaces. This local cache is provided to increase the performance of Oracle WebCenter Spaces. For instructions on configuring the Java Object Cache among all the servers running Oracle WebCenter Spaces, see Section F.1, Configuring the Java Object Cache.

6.4.14 Configuring the Distributed Notifications for the MDS Repository

In high availability environments, Oracle recommends that you configure distributed notifications for the MDS repository. For instructions on configuring distributed notifications for the MDS repository, see Appendix G, Configuring Distributed Notifications for MDS.

6.4.15 Configuring Oracle WebCenter for Replication

Use the procedures in this section to configure Oracle WebCenter for replication. Clustering Requirement The application must be deployed to an Oracle WebLogic Cluster. This automatically establishes a replication channel for the multiple instances of the application. Oracle ADF Replication Oracle WebCenter relies on Oracle ADF components, therefore, essential that Oracle ADF is configured properly. The following tag should be present in the adf-config.xml file, one of the Application Resources, for a stateful application: adfc:adf-controller-config adfc:adf-scope-ha-supporttrueadfc:adf-scope-ha-support adfc:adf-controller-config In WebCenter applications, this is already been enabled by default. Note: In a Unicast cluster, the default replication channel is configured using the Listen address of each managed server. Therefore, the Listen address should be configured to be a specific IP address or host name, instead of being configured to listen on Any. 6-66 Oracle Fusion Middleware High Availability Guide Application Replication Applications must also have replication enabled. Oracle WebLogic Server allows several types of persistent stores for replication. For more information on persistent stores, see Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server. For Oracle WebCenter, applications are enabled by default with the following setting in the weblogic.xml file: session-descriptor persistent-store-typereplicated_if_clusteredpersistent-store-type session-descriptor The replicated_if_clustered setting disables replication for stand-alone application environments, and uses in-memory replication within a cluster environment. Ensure that any Oracle WebCenter Portal Application is configured for in-memory replication.
