(Multiple values for CCRAC_SLVM_VGS and CCRAC_INSTANCE_PKGS should
be separated by space).
If multiple sets of Oracle instances accessing different databases
are configured in your environment and need Continentalclusters
recovery support, repeat this set of parameters with an
incremented index. For example,
CCRAC_ENV[0]=/etc/cmconcl/ccrac/db1/db1EnvFile_xpca.env
CCRAC_SLVM_VGS[0]=ccracvg1
ccracvg2CCRAC_INSTANCE_PKGS[0]=ccracPkg1
ccracPkg2CCRAC_CLUSTER[0]=PriCluster1
CCRAC_ENV_LOG[0]=/tmp/db1_prep.log
CCRAC_ENV[1]=/etc/cmconcl/ccrac/db2/db2EnvFile_srdf.env
CCRAC_CVM_DGS[1]=racdg01 racdg02
CCRAC_INSTANCE_PKGS[1]=ccracPkg3 ccrac
Pkg4CCRAC_CLUSTER[1]=PriCluster2
CCRAC_ENV_LOG[1]=/tmp/db2_prep.log
CCRAC_ENV[2]=/etc/cmconcl/ccrac/db3/db3EnvFile_xpca.env
CCRAC_SLVM_VGS[2]=ccracvg5 ccracvg6
CCRAC_INSTANCE_PKGS[2]=ccracPkg5 ccracPkg6
CCRAC_CLUSTER[2]=PriCluster2
e. Copy the edited file to the final directory:
# cp ccrac.config.mycopy \/etc/cmconcl/ccrac/ccrac.config
f. Copy file /etc/cmconcl/ccrac/ccrac.config to all the other nodes of the cluster.
g. Login as root on one node of the recovery cluster and repeat steps “b” through “f” from
above. If the recovery cluster is configured to recover the Oracle RAC instances for more
than one primary cluster, the ccrac.config file on the recovery cluster should contain
information for all the primary clusters.
8. Configure Continentalclusters Recovery Group for Oracle RAC instance. If you are using an
individual package for each RAC instance, define one recovery group for each Oracle RAC
instance recovery. The PRIMARY_PACKAGE specified for the Oracle RAC instance recovery
group is the name of the instance package configured on the primary cluster. The
RECOVERY_PACKAGE specified for the RAC instance recovery group is the corresponding
instance package name configured on the recovery cluster. For example:
RECOVERY_GROUP_NAME instanceRG1
PRIMARY_PACKAGE ClusterA/instancepkg1
RECOVERY_PACKAGE
ClusterB/instancepkg1'
RECOVERY_GROUP_NAME instanceRG2
PRIMARY_PACKAGE ClusterA/instancepkg2
RECOVERY_PACKAGE
ClusterB/instancepkg2'
Packages instancepkg1 and instancepkg2 are configured to run on primary cluster
“ClusterA”. Packages instancepkg1’ and instancepkg2’are configured to be restarted
or recovered on the recovery cluster “ClusterB” upon primary cluster failure.
If you are using one multi-node package to package all RAC instances, define only one
recovery group for the RAC MNP Package. For example.
RECOVERY_GROUP_NAME manufacturing_recovery
PRIMARY_PACKAGE ClusterA/man_rac_mnp
RECOVERY_PACKAGE ClusterB/man_rac_mnp
