Configuring the second cluster

1. Modify the ClusterService group in the second cluster for global cluster configuration.

   See Modifying the ClusterService group for global clusters

2. Create a configuration that is similar to the one in the first cluster.

   You can do this by either using Cluster Manager (Java Console) to copy and paste resources from the primary cluster, or by copying the configuration of the appgroup and appgroup_rep groups from the main.cf file in the primary cluster to the secondary cluster.

3. To assign remote administration privileges to users, configure users with the same name and privileges on both clusters.

   See User privileges in global clusters.

4. Make appropriate changes to the configuration. For example, you must modify the SystemList attribute to reflect the systems in the secondary cluster.

   Make sure that the name of the service group (appgroup) is identical in both clusters.

   VVR best practice is to use the same disk group and RVG name on both sites.

   If the volume names are the same on both sides, the Mount resources will mount the same block devices, and the same Oracle instance will start at the secondary in case of a failover.
