CUCM IM&P 15SU2: issues with IMDB replication

raziel1978kain

Hello,

we have a CUCM IM&P 15SU2 cluster (2 nodes) and we have issues with the IMDB replication (which are causing issues with the Jabber logins).

Based on the document at the link

https://www.cisco.com/c/en/us/support/docs/unified-communications/jabber/212471-jabber-login.html#toc-hId-709326440

we have followed the steps to resolve the IMDB replication issues but, after the procedure, we still have the following:

----------

admin:utils imdb_replication status
Running IMDB DSN (ttsoft, ttlogin, ttreg) replication checks on all nodes in cluster ...
NOTE: For diagnostic test to run, ports 6603, 6604 & 6605 must be open on any firewalls between IM&P Servers

Sub Cluster Name / Id :: DefaultCUPSubcluster / 1000
Checking connectivity & removing old data prior to running diagnostic
Cisco Presence Datastore Replication
<CUCM IM&P Subscriber> -> <CUCM IM&P Publisher> Failed
<CUCM IM&P Publisher> -> <CUCM IM&P Subscriber> Failed
Gathering Debug Info for failed DSN ... please wait

a.write_to_file("%s\n" % (result[0].decode('utf-8')))

----------

N.B.: we have already checked that the ports 6603, 6604, and 6605 are open.

What's wrong?

TIA and regards.

Hello @Nithin Eluvathingal,

thanks for the link, but we already had checked the DB replication, which is fine; where we have issues is only with the IMDB (In-memory Database) replication, which is something else compared to the "classic" DB replication.

Regards.

As far as I know, both IMP and CUCM database troubleshooting remain the same. That’s why I sent you the link to fix the database.

What do the following commands say about the IMP nodes?

  • utils dbreplication runtimestate
  • utils diagnose test
  • utils network connectivity

Hello @Nithin Eluvathingal,

at last, we had to solve the issue with the TAC, due to the following bug:
