Pre-Installation Steps for OracleAS Cluster (Identity Management)
9-2 Oracle Application Server Installation Guide
■
Install the OracleAS Metadata Repository in an existing database using the
OracleAS RepCA. See the Oracle Application Server Metadata Repository Creation
Assistant User’s Guide for supported database configurations.
For OracleAS Cluster (Identity Management) configurations, Oracle recommends
using a high availability database configuration such as Real Application Clusters or
cold failover cluster.
You can only install one OracleAS Cluster (Identity Management) on an OracleAS
Metadata Repository.
Always Select the Same Components
Because the installer clusters the components in an OracleAS Cluster (Identity
Management) configuration, you need to select the same components in the Select
Configuration Options screen for all the nodes in the cluster.
For example, if you select Oracle Internet Directory, OracleAS Single Sign-On, and
Oracle Delegated Administration Services for the installation on node 1, then you have
to select the same set of components in subsequent installations.
Clustering will fail if you select different components in each installation.
Configurations
You can install OracleAS Cluster (Identity Management) in these configurations:
■
OracleAS Cluster (Identity Management). See Section 9.5 .
■
Distributed OracleAS Cluster (Identity Management). See Section 9.6 .
9.2 Pre-Installation Steps for OracleAS Cluster (Identity Management)
Before installing an OracleAS Cluster (Identity Management) configuration, you need
to set up the following items:
■
Section 9.2.1, "Use the Same Path for the Oracle Home Directory (recommended)"
■
Section 9.2.2, "Synchronize Clocks on All Nodes"
■
Section 9.2.3, "Configure Virtual Server Names and Ports for the Load Balancer"
■
Section 9.2.4, "Configure Your LDAP Virtual Server"
9.2.1 Use the Same Path for the Oracle Home Directory (recommended)
For all the nodes that will be running Oracle Identity Management components, use
the same full path for the Oracle home. This practice is recommended, but not
required.
Note: For OracleAS Cluster (Identity Management) configurations,
you never select the "Oracle Identity Management and OracleAS
Metadata Repository
" option in the installer. You always select the
Oracle Identity Management option. This is why you need an
existing OracleAS Metadata Repository.
