9.7 Post-Installation Steps
After installing Oracle Identity Management components on all nodes, reconfigure
your load balancer to direct requests to all nodes. Before you started the installation,
you had configured the load balancer to direct requests to node 1 only. See
Section 9.2.4, "Configure Your LDAP Virtual Server" .
This section contains the following post-installation steps:
■
Section 9.7.1, "Cluster the OC4J_Security Instance for State Replication (First
Oracle Delegated Administration Services node only)"
■
Section 9.7.2, "Changing the Ports for Oracle Internet Directory"
■
Section 9.7.3, "Update targets.xml (Case 2 only)"
9.7.1 Cluster the OC4J_Security Instance for State Replication (First Oracle Delegated
Administration Services node only)
To ensure that Oracle Application Server maintains the state of stateful Web
applications across DCM-Managed OracleAS Cluster, you need to configure state
replication for the Web applications. Configure state replication only on the first node
where Oracle Delegated Administration Services is installed.
To configure state replication for the OC4J_Security instance, do the following:
1. Using the Application Server Control Console, navigate to the Application Server
Home page for the instance that contains Oracle Delegated Administration
Services.
2. Select the OC4J_SECURITY link on the Application Server Home page.
3. Select the Administration link on the OC4J Home Page.
4. Select the Replication Properties link in the Instance Properties area.
5. Scroll down to the Web Applications section. Figure 9–3 shows this section.

6. Select the Replicate session state checkbox.
Optionally, you can provide the multicast host IP address and port number. If you
do not provide the host and port for the multicast address, it defaults to host IP
address 230.230.0.1 and port number 9127. The host IP address must be between
224.0.0.2 through 239.255.255.255. Do not use the same multicast address for both
HTTP and EJB multicast addresses.
