Protection groups enable a set of clusters to tolerate and recover from disaster by managing the resource groups for services. A protection group contains application resource groups and properties for managing data replication for those application resource groups.
Observe the following general guidelines when you configure a protection group:
Partnerships –You must create a partnership before you can create a protection group for that partnership. Protection groups can exist only in a partnership.
Duplicate application resource group configuration – You can duplicate the application resource group configuration on partner clusters. The configuration for a protection group is identical on partner clusters, so partner clusters must have the application resource groups of the protection group defined in their configuration. The Geographic Edition software propagates protection group configurations between partners.
Data replication – You can specify a data replication type in the protection group to indicate the mechanism that is used for data replication between partner clusters. When a service is protected from disaster by data replication, the protection group also contains replication resource groups. Protection groups link an application in a resource group with the application data that should be replicated. This linkage and replication enable the application to fail over seamlessly from one cluster to another cluster.
Replicating the Oracle Solaris boot environment – Do not replicate an Oracle Solaris boot environment between two systems. Doing so is not appropriate for disaster recovery environments, as it might introduce instability in the target boot environment.
Each data replication product has its own additional requirements when configuring a protection group. For more information, see the appropriate Geographic Edition manual for the data replication software that you will use:
