NOTE:
• Do not add any comments after specifying the critical and managed packages.
• Always set auto_run parameter to yes for failover packages configured as critical or
managed packages.
• The packages configured with mutual dependency must not be configured as critical or
managed packages.
4. Re-apply the Site Controller Package configuration.
# cmapplyconf -v -P /etc/cmcluster/hrdb_sc/hrdb_sc.config
After applying the Site Controller Package configuration, you can run the cmviewcl command
to view the packages that are configured.
Configure Continentalclusters
Ensure that the Continentalclusters software is installed on all nodes in both primary and recovery
cluster.
Configure a Continentalclusters Recovery Group
For each Site Controller Package in the cluster, configure a recovery group using the corresponding
packages at the primary and recovery cluster.
Complete the following steps to configure a recovery group in Continentalclusters:
1. Edit the Continentalclusters configuration file to specify the recovery groups. Specify the Site
Controller Package configured in primary cluster as a PRIMARY_PACKAGE and the Site
Controller Package configured in the recovery cluster as a RECOVERY_PACKAGE in the recovery
group.
For example:
RECOVERY_GROUP_NAME hrdb_sc_group
PRIMARY_PACKAGE <primary_cluster_name>/hrdb_sc
RECOVERY_PACKAGE <recovery_cluster_name>/hrdb_sc
2. Check the configuration file syntax.
# cmcheckconcl -v -C <Continental_cluster_config_file_name>
3. Apply the configuration.
# cmapplyconcl -C <Continental_cluster_config_file_name>
At this point, you have completed configuring SADTA in the 3DC solution with the RAC database.
It is recommended that you verify the setup during the planned downtime for maintenance using
the procedure mentioned in “Verifying the Three Data Center Environment” (page 139).
Verifying the Three Data Center Environment
To verify the setup:
• Preview the data replication storage failover by using the cmdrprev command.
• Test the application startup at the recovery cluster.
• Test Continentalclusters recovery using the cmrecovercl command in the recovery
cluster.
