Configure Continentalclusters and Continentalclusters Recovery Group
Ensure that the Continentalclusters software is installed on all nodes in both primary and recovery
cluster. To configure the Continentalclusters, complete the procedure described in “Designing
Continentalclusters” (page 36). For each application in the 3DC solution, configure a recovery
group using their 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 primary package configured in the primary cluster as PRIMARY_PACKAGE and the recovery
package configured in the recovery cluster as RECOVERY_PACKAGE in the recovery group.
For Example:
RECOVERY_GROUP_NAME <recovery_group_name>
PRIMARY_PACKAGE <primary_cluster_name>/<primary_package_name>
RECOVERY_PACKAGE <recovery_cluster_name>/<recovery_package_name>
When deploying complex workloads, specify the Site Controller package configured in the
primary cluster as PRIMARY_PACKAGE and the Site Controller package configured in the
recovery cluster as RECOVERY_PACKAGE in the recovery group.
For Example:
RECOVERY_GROUP_NAME <recovery_group_name>
PRIMARY_PACKAGE <primary_cluster_name>/<site_controller_package_name>
RECOVERY_PACKAGE <recovery_cluster_name>/<site_controller_package_name>
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>
For more information on Continentalclusters configuration, see “Designing
Continentalclusters” (page 36).
You have now configured an application in the 3DC solution. At any point in time, you can
preview the data replication storage failover on any node in the 3DC solution using the
procedure mentioned in “Previewing the Data Replication Storage Failover by Using cmdrprev”
(page 461). It is also recommended to verify the setup during the planned downtime for
maintenance using the procedures mentioned in the sections “Testing the application startup
at the recovery cluster” (page 462) and “Testing Continentalclusters Recovery Using cmrecovercl
in the Recovery Cluster” (page 463).
