How To Fix CUCM Database Replication Issues

So if you have been working with Cisco Unified Communications Manager for a while then you are pretty familiar with the Database Replication Issues.

I ran into this a few times and thought it would be a good idea to have a post about it.

There are a few reasons for this and it seems to happen a lot in a VMware CCIE Voice environment.

So let's get straight to the resolution steps:

1. Remove CUCM Subscriber from the Group
2. Disable all services on the Subscriber
3. Login to your Publisher and issue "utils dbreplication repair all" command

This process can take some time so sit back or just work on some other tasks before coming back to your CUCM cluster.

Hope this helped!
