cluster.
# /opt/cmconcl/bin/ccrac_mgmt.ksh stop
To stop a specific set of RAC instance packages.
# /opt/cmconcl/ccrac_mgmt.ksh -i <indexNumber> stop
<IndexNumber> is the index used in the /etc/cmconcl/ccrac/ccrac.config file for
the target set of the Oracle RAC instance packages.
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-PKG package 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
