The top part of the figure lists the steps for transforming to an OracleAS Cluster (Identity Management) topology, and the bottom part of the figure shows the nodes in the environment with lines connecting them. Numbers on the lines indicate the step associated with the line.

There are eight steps:

  1. Check high availability requirements. This step is not shown in the figure.

  2. Back up your environment. This step is not shown in the figure.

  3. Transform database to Real Application Clusters database. In this step, you transfer the data from the single-instance OracleAS Metadata Repository database to the Real Application Clusters database.

  4. Change source Identity Management to use Real Application Clusters database. In this step, you associate the Identity Management instance with the Real Application Clusters database.

  5. Transform source Identity Management to use virtual server names on the load balancer. In this step, you reconfigure the Identity Management instance to use the LDAP and HTTP virtual server names on the load balancer.

  6. n/a (this step applies only when transforming to distributed OracleAS Cluster (Identity Management))

  7. Change middle tier to use (1) virtual server names on the load balancers and (2) Real Application Clusters. In this step, you reconfigure the middle-tier instance to use the virtual server names on the load balancer and the OracleAS Metadata Repository that is running on the Real Application Clusters database.

  8. Install additional instances. In this step, you install additional Oracle Identity Management instances. You cluster the instance with the source Oracle Identity Management instance. This new instance also uses the virtual server names on the load balancer.
