Configuring Single Instance Applications in CFS/CVM Environments in Continentalclusters, November 2006

CCRAC_CVM_DGS - CVM disk groups configured for the device specified in the above

environment file for variable DEVICE_GROUP. These are the disk groups used by the

associated single instance application package. It is important that all of the disk groups

configured for the specified DEVICE_GROUP are listed. If only partial of the configured disk

groups are listed, the device will not be prepared properly and the storage will result in an

inconsistent state.

CCRAC_CLUSTER - Serviceguard cluster name configured as the primary cluster of the

corresponding single instance application package. This parameter is mandatory.

CCRAC_INSTANCE_PKGS - in a single instance application with CFS/CVM environment, this

parameter is set to the primary application package name.

CCRAC_ENV_LOG - logfile specification for the storage preparation output.

3) Configure either Continuous Access XP or EMC SRDF for data replication. Provide the

location of the environment file as a value for the CCRAC_ENV parameter. Provide the CVM

disk group name as a value for the CCRAC_CVM_DGS parameter.

Eg:

CCRAC_ENV[0]=/etc/cmcluster /ccrac/db1EnvFile_xpca.env

CCRAC_CVM_DGS [0]=<disk_group_name>

CCRAC_INSTANCE_PKGS [0] =<package_names>

CCRAC_CLUSTER [0]=<primary_cluster_name>

CCRAC_ENV_LOG[0]=/tmp/db1_prep.log

NOTE: Recovery of single instance applications extends the use of ccrac.config which was originally

meant for recovery of Oracle RAC with CC, including Oracle RAC CVM/CFS configurations

4) Transfer this file to all nodes in both primary and the recovery cluster under the

/etc/cmconcl/ccrac directory.

$whoami

root

$rcp ccrac.config ccia2: /etc/cmconcl/ccrac

$rcp ccrac.config ccia3: /etc/cmconcl/ccrac

$rcp ccrac.config ccia4: /etc/cmconcl/ccrac

5.7 Starting the monitor package

1) Start the monitor package on the recovery cluster.

$cmrunpkg ccmonpkg

2) View the status of the Continentalclusters primary and recovery cluster using cmviewconcl –v

command.

$cmviewconcl –v
