Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

After applying the Site Controller Package configuration, run the cmviewcl command to
view the packages that are configured.
5. Repeat the above steps in the Recovery cluster as well.
Configuring the Site Controller Package at the recovery cluster
The site controller package needs to be configured in the recovery cluster. The procedure to
configure the Site Controller Package is identical to the procedure in configuring complex workload
in Continentalclusters with SADTA. For more information on configuring the Site Controller Package
for Oracle RAC database with ASM in SADTA, see “Configuring the Site Controller Package with
Complex Workload packages in the Recovery Cluster” (page 140)
Configuring the Site Safety Latch Dependencies at the recovery cluster
After the Site Controller Package configuration is applied, the corresponding Site Safety Latch is
also configured automatically in the cluster. This section describes the procedure to configure the
Site Safety Latch dependencies.
Complete the following procedure to configure the Site Safety Latch dependencies in the recovery
cluster:
1. Add the EMS resource details in ASM DG package configuration file.
RESOURCE_NAME /dts/mcsc/hrdb_sc
RESOURCE_POLLING_INTERVAL 120
RESOURCE_UP_VALUE != DOWN
RESOURCE_START automatic
You must apply the modified ASM DG package configuration using the
cmapplyconf
command.
2. Verify the Site Safety Latch resource configuration at both sites. Run the following command
to view the EMS resource details:
# cmviewcl -v –p <ASM_DG_pkg_name>
3. Configure the Site Controller Package in recovery cluster with the RAC MNP stack in recovery
cluster.
site cc2_site1
critical_package <cluster2_RAC_DB_pkg_name>
managed_package <cluster2_ASM_DB_pkg_name>
NOTE: Do not add any comments after specifying the critical and managed packages.
4. Re-apply the Site Controller Package configuration.
# cmapplyconf -v -P <site_controller_configuration_file>
After applying the Site Controller Package configuration, run the
cmviewcl
command to view the packages that are configured.
5. Repeat the above steps in the Recovery cluster as well.
Database with ASM in the Continentalclusters in the primary cluster
The procedure to start the disaster tolerant Oracle RAC database with ASM is identical to the
procedure for starting a complex workload in a Continentalclusters. Issue the
cmrunpkg
command with the site controller package name managing the Oracle RAC/ASM workload at the
primary cluster as the argument.
# cmrunpkg siteController1
