Management) Configurations
Pre-Installation
Before starting the middle-tier installation, configure the LDAP load balancer that you
are using for Oracle Internet Directory so that it points to only one Oracle Internet
Directory node.
Installation
When installing middle tiers against OracleAS Cluster (Identity Management)
configurations, follow the steps for middle tier installation described in Oracle
Application Server Installation Guide for the middle tier release you are using.
When the installer prompts for the Oracle Internet Directory host and port, enter the
LDAP virtual host name configured on the load balancer and the associated port.
Post-Installation
After installing the middle tiers, you can reconfigure the LDAP load balancer to point
to all the Oracle Internet Directory nodes.
