General Health and Troubleshooting Tips
3—This value indicates that replication is bad in the cluster.
•
4—This value indicates that replication setup did not succeed.

To verify database replication using Cisco Unified Reporting, perform the following tasks:
Step 3
From the Navigation drop-down list box in the upper, right corner in Cisco Unified Communications
a.
Manager Administration, choose Cisco Unified Reporting.
After Cisco Unified Reporting displays, click System Reports.
b.
Generate and view the Cisco Unified CM Database Status report, which provides debugging
c.
information for database replication.
Once you have generated the report, open it and look at the Cisco Unified CM Database Status. It
gives the RTMT replication counters for all servers in the cluster. All servers should have a replicate
state of 2, and all servers should have the same number of replicates created.
If you see any servers whose replicate states are not equal to 2 in the above status check, inspect the
"Replication Server List" on this report. It shows which servers are connected and communicating
with each node. Each server should show itself as local (in its list) and the other servers as active
connected. If you see any servers as dropped, it usually means there is a communication problem
between the nodes.
If you want to do so, generate and view the Cisco Unified CM Database Status report, which
d.
provides a snapshot of the health of the Cisco Unified Communications Manager database.
To verify database replication using RTMT, perform the following tasks:
Step 4
Open the Cisco Unified Real-Time Monitoring Tool (RTMT).
a.
Click the CallManager tab.
b.
Click Database Summary. The Replication Status pane displays.
c.
The following list shows the possible values for the Replication Status pane:
0—This value indicates that replication has not started. Either no subsequent nodes (subscribers)
•
exist, or the Cisco Database Layer Monitor service is not running and has not been running since
the subscriber was installed.
1—This value indicates that replicates have been created, but their count is incorrect.
•
2—This value indicates that replication is good.
•
3—This value indicates that replication is bad in the cluster.
•
4—This value indicates that replication setup did not succeed.
•
To view the Replicate_State performance monitoring counter, choose System > Performance >
d.
Open Performance Monitoring. Double-click the publisher database server (first node) to expand
the performance monitors. Click Number of Replicates Created and State of Replication.
Double-click Replicate_State. Click ReplicateCount from the Object Instances window and click
Add.
Tip
If all the servers have a good RTMT status, but you suspect the databases are not in sync, you can run
Step 5
the CLI command utils dbreplication status (If any of the servers showed an RTMT status of 4, proceed
