Oracle Data Guard Replication Resource Groups

When an Oracle Data Guard Broker configuration that is controlling the Oracle Data Guard software is added to a protection group, the Sun Cluster Geographic Edition software creates a special replication resource for the specific Oracle Data Guard Broker configuration in the replication resource group. By monitoring these replication resource groups, the Sun Cluster Geographic Edition software is able to monitor the overall status of replication. One replication resource group with one replication resource for each Oracle Data Guard Broker configuration is created for each protection group.

The name of the replication resource group conforms to the following format:

ODGProtectiongroupName-odg-rep-rg.

The replication resource in the replication resource group monitors the replication status of the Oracle Data Guard Broker configuration on the local cluster, which is reported by the Oracle Data Guard Broker software.

The name of the replication resource conforms to the following format:

ODGBrokerConfigurationName-odg-rep-rs.

In Oracle Data Guard, a data replication resource is enabled when the protection group is activated in the cluster. Consequently, in Oracle Data Guard, in a cluster in which the protection group is deactivated, the data replication status appears as unknown.
