When you finish configuring a recovery pair with RAC support, your systems must have sets of files similar to those shown in Figure 5.
NOTE: If you are configuring Oracle RAC instances in Serviceguard packages in a CFS or CVM environment, do not specify the CVM_DISK_GROUPS, and CVM_ACTIVATION_CMD fields in the package control scripts as CVM disk group manipulation is addressed by the disk group multi node package.

NOTE: Starting from Continentalclusters Version A.08.00, there are no managed object files in the /etc/cmconl/instances directory.
Serviceguard/Serviceguard extension for RAC and Oracle Clusterware configuration
The following configurations are required for Continentalclusters RAC instance recovery support for the cluster environment that has with Serviceguard/Serviceguard Extension for RAC and CRS (Oracle Cluster Software):
1.The Oracle RAC environment having Serviceguard/Serviceguard Extension for RAC and Oracle Cluster Software must follow all the recommendations listed in the Serviceguard and SGeRAC manuals for running with CRS (Oracle Cluster Software).
2.At start up, CRS must not automatically activate the volume groups that are configured for the database. The file /var/opt/oracle/oravg.conf must not exist on any node of the primary and recovery cluster.
3.The CRS storage (OCR and voting disk) must be configured on a separate volume group that is separate from the databases which are accessed by the RAC instances.
4.The RAC instance attribute AUTO_START listed in the CRS service profile must be set to 2 on both primary and recovery clusters so that the instance does not automatically start when the node rejoins the cluster. Log in as the oracle administrator and change the attribute value:
