CUC 8.6.2.22900-9: issue with DB replication

[raziel78kain]

Hello,

we have a Cisco Unity Connection (CUC) 8.6.2.22900-9 cluster.

We suspect to have an issue with the DB replication: in fact, we have noted that the replicate is not in sync for the table "replicationdynamic"; is it an issue or a normal condition?

TIA and regards.

What symptom caused you to notice this?

Is the table always out of sync or is it a transient thing?

Are the replication queues being cleared out?

A dynamic table can drift out of sync momentarily as a record is written on one node. Until the replication syncs that change the table is technically out of sync. People normally don't notice this unless you turned on the out of sync notification service parameter.

Hello Jonathan,

apparently, this thing is not causing any negative effect...

The table "replicationdynamic" is not synchronizing from several hours, and it's the only one to not to be synchronized.

Meanwhile, we have found the following thread on this forum:

Even if it's referring to an old version of CUCM (a 6.1.4.2000-2), the following message is interesting:

(3) ***** PLEASE IGNORE MISMATCHES IN ReplicationDynamic TABLE *****

So, what is this table used for? Is its synchronization mandatory or optional?

By the way: the Replication State is 2 (= Good) for both the nodes...

Regards.
