This sample file describes the following configuration:

• Two SF 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.

• Hitachi True Copy is used to replicate data between the sites.

• The HTC disk groups that are replicated across the sites using HTC technology and the replication mode are specified under the HTC resource in the database group. The CVM disk group that comprises the HTC disk group must be configured under the CVMVolDg resource in the database group.

• The database group will be online on the primary cluster. The HTC resource determines where the database group will be brought online.

• 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 database group oradb_grp_fd on the secondary is configured for fire drill.

• When the group oradb_grp_fd is brought online, the HTCSnap creates a snapshot of the disk group configured under the HTC resource in the database group oradg_grp.

  Further, the Oracle database and the associated volumes and mount points configured under the service group oradb_grp_fd are brought online using the snapshots created by HTCSnap.
