Update the Continentalclusters configuration file by specifying the new rehearsal package name for the REHEARSAL_PACKAGE parameter in the recovery group definition. Distribute the Continentalclusters configuration by reapplying the configuration file.
Removing a Package from the Continentalclusters
To remove a package from the Continentalclusters configuration, you must first remove the recovery group from the Continentalclusters configuration file.
Removing the package does not require you to bring down either cluster. However, in order to implement the new configuration, the following steps are required:
1.Edit the Continentalclusters configuration file, deleting the recovery group.
2.Halt the monitor packages that are running on the clusters.
3.Use the cmapplyconcl command to apply the new Continentalclusters configuration.
4.Restart the monitor packages on both clusters.
5.Use the Serviceguard cmdeleteconf command to remove each package in the recovery group.
6.View the status of the Continentalclusters.
# cmviewconcl
Changing Monitoring Definitions
It is allowable to change the monitoring definitions in the configuration without bringing down either cluster. This includes: adding, removing, or changing the cluster events, changing the timings, and adding, removing, or changing the notification messages.
Use the following steps to change the monitoring definitions:
1.Edit the Continentalclusters configuration file to incorporate the new or changed monitoring definitions.
2.Halt the monitor packages on both clusters.
3.Use the cmapplyconcl command to apply the new configuration.
4.Restart the monitor packages on both clusters.
5.View the status of the Continentalclusters.

Checking the Status of Clusters, Nodes, and Packages
To check on the status of the Continentalclusters and associated packages, use the cmviewconcl command, which lists the status of the clusters, associated package status, and configured events status. This command also displays the mode of the recovery group, if configured.
The following is an example of cmviewconcl output in a situation where there is a single recovery group for which the primary cluster is cjc838 and the recovery cluster is cjc1234.
#cmviewconcl
WARNING: Primary cluster cjc838 is in an alarm state (cmrecovercl is enabled on recovery cluster cjc1234)
