Chapter 3 Managing and Monitoring the Health of Cisco Unified Communications Manager Systems

General Health and Troubleshooting Tips

Recommended Action

Step 1 Reset cluster replication by using CLI commands. Ensure servers in the cluster are online with full IP

connectivity for this to work. Confirm that all servers in the cluster are online by using platform CLI and

Cisco Unified Reporting.

Step 2 If the servers are in Replication State 2, use the utils dbreplication repair server name command on

the publisher server.

If the servers are not in Replication State 2, use the utils dbreplication stop command on all subscriber

servers.

Then, use the utils dbreplication stop and then utils dbreplication reset all commands on the publisher

server.

Reset Database Replication When Reverting to Prior Release

If you revert the servers in a cluster to run an older product release, you must manually reset database

replication within the cluster. To reset database replication after you revert all the cluster servers to the

older product release, use the utils dbreplication reset command all on the publisher server.

When you switch versions by using Cisco Unified Communications Operating System Administration

or the CLI, you get a message reminding you about the requirement to reset database replication if you

are reverting to an older product release.
