Failover of Oracle RAC Instances to the Recovery Site

Upon a disaster that disables the primary cluster, to start up a Continentalclusters recovery process, run the following command:

#cmrecovercl

For the cluster environment running with Serviceguard and Oracle Clusterware, confirm that the Clusterware daemons and the required Oracle services, such as listener, GSD, ONS, and VIP, are started on all the nodes, which the database instance are configured to run before initiating the recovery process.

If you have configured CFS or CVM in your environment, ensure the following:

•The SG-CFS-PKG(system multi-node package) is up and running.

The SG-CFS-PKGpackage is not part of the continentalclusters configuration.

•The cmrecovercl command is run from the CVM master node. Use the following command to display the CVM master node:

# vxdctl -c mode

Starting with Continentalclusters A.07.00, recovery groups of applications using CFS or CVM can be recovered by running the cmrecovercl command from any node at the recovery cluster.

NOTE: Make sure that the primary site is unavailable and all of the Oracle RAC instance packages are not running on the primary cluster before initiating the recovery process.

The Continentalclusters command, cmrecovercl prepares the configured storage for Oracle RAC instances shared access only when the file /etc/cmconcl/ccrac/ccrac.config exists. If this file does not exist, the configured storage will not be prepared for shared access before recovering the Oracle RAC instance packages. As a result, if Continentalclusters recovery group configuration includes Oracle RAC instance packages, these packages will not be able to start or operate successfully.

The recovery process will startup the configured Oracle RAC instance packages as well as other application packages configured in the Continentalclusters environment.

If the Continentalclusters Oracle RAC support is enabled (the /etc/cmconcl/ccrac/ ccrac.config file exists), the following messages will be prompted to the user when the command cmrecovercl is invoked and confirmations are needed for the process to proceed.

WARNING: This command will take over for the primary cluster LACluster by starting the recovery package on the recovery cluster NYCluster. You must follow your site disaster recovery procedure to ensure that the primary packages on LACluster are not running and that recovery on NYCluster is necessary. Continuing with this command while the
