The sample service group describes the following configuration:

• Two Storage Foundation for Oracle RAC clusters, comprising two nodes each, hosted at different geographical locations.

• A single Oracle database that is stored on CFS.

• The database is managed by the VCS agent for Oracle.

  The agent starts, stops, and monitors the database.

• The database uses the Oracle UDP IPC for database cache fusion.

• A common IP address is used by Oracle Clusterware and database cache fusion. The private IP address is managed by the PrivNIC agent for high availability.

• One virtual IP address must be configured under the ClusterService group on each site for inter-cluster communication.

• The Oracle Cluster Registry (OCR) and voting disk are stored on CFS.

• Volume Replicator (VVR) is used to replicate data between the sites.

• The shared volumes replicated across the sites are configured under the RVG group.

• The replication link used by VVR for communicating log information between sites are configured under the rlogowner group. This is a failover group, and remains online from the cvm master node. The PreOnline trigger for the RVGLogOwner agent should be enabled.

  Please see the section "CVM master node needs to assume the logowner role for VCS managed VVR resources" in the Cluster Server Bundled Agents Reference Guide for more info.

• The database group is configured as a global group by specifying the clusters on the primary and secondary sites as values for the ClusterList group attribute.

• The fire drill service group oradb_grp_fd creates a snapshot of the replicated data on the secondary site and starts the database using the snapshot. An offline local dependency is set between the fire drill service group and the application service group to make sure a fire drill does not block an application failover in case a disaster strikes the primary site.
