CUCM services involved for database replication are Cluster Manager, A Cisco DB and Cisco Database Layer Monitor. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. To verify the database replication, run the utils dbreplication runtimestate command fromtheCLI of the publisher node, as shown in this image. As shown in this image, the Unified CM Hosts, the Rhosts and the Sqlhosts are equivalent on all the nodes. utils dbreplication repair -- in CUCM 5.x, this command meant a reset of the replication, whereas, in CUCM 6.x and higher versions, this means a repair of the data. necessary to troubleshoot and resolve those issues. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are After you complete Step4, if there are no issues reported, run the. Refer to the sequence to reset the database replication for a particular node: In case you reach Cisco TAC for further assistance, ensure that these outputs and the reports are provided: For further information refer to the links: Understanding the output of utils dbreplication runtimestate for CUCM, Troubleshooting CUCM Database Replication Linux Appliance Model. thesubscribers syncs the time with the publisher. Database replication commands must be run from the publisher. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes).

If the RTT is unusally (2) Execute the utils dbreplication stop command on the Publisher. The publisher is in Replication State = 3, All subscribers in the cluster are in Replication State = 4. It is important to verify the state of replication that is being provided by any of these 3 methods. Thanks for creating this Patrick. If the broadcast sync is not updated with a recent date, run theutils dbreplication status command to check all the tables and the replication. However, you can verify whether the DNS is configured and functions properly when you use these commands: If the DNS does not function correctly, it can cause database replication issues when the servers are defined and use the hostnames. .

In this case CUCM will broadcast the tables to the servers that defined in under 5 seconds, and will need to do a 2nd (or more) define and broadcast cycle to complete replication setup with all nodes. If any node has a state other than 2, continue to troubleshoot. To confirm that replication is setting up in a single batch, run utils dbreplication stop all followed by utils dbreplication reset all from the CUCM publisher, and then verify the sequence of logs using file list activelog cm/trace/dbl/* date detailed from the publisher CLI. Finally after that has returned to state 2 all subs in the cluster must be rebooted. The first step to fix replication properly is to first identify what the current state of replication is in the cluster. If no, contact Cisco Database CLI Output Cisco Database Installation Service Cisco Database Layer Monitor Cisco Database Library Trace Cisco Database Notification Service Cisco Database Replicator Server, Cisco Informix Database Service Event Viewer-Application Log Event Viewer-System LogYou can also take a look in the ccm.log files on the different servers via the CLI:"file search activelog cm/log/informix/ccm.log error""file search activelog cm/log/informix/ccm.log fail".

Cluster : Server 1-5 * 1 min = 5 min, + 6-10 * 2 min = 10 min, Same as above, but may need to be used in cases where above command fails. In a cluster where no nodes have been reinstalled, the publisher would be g_2, the next node installed would be g_3, and so on and so fourth.11: This shows the RTMT states for database replication. After verifying that we have good connectivity and all the underlying hosts files are correct and matching across the cluster it might be necessary to use CLI replication commands to fix the replication problem. Then choose "Database Status Report", and generate a new report. needs to be opened. The show network cluster command checksfor And also try to get this below fixed. If the DNS does not functions correctly, it can cause the +11-12 * 3 min = 6 min, Repltimeout should be set to 21 Starting in CUCM 10.0(1), repltimeout is slightly less important because the Publisher will now queue define requests instead of waiting for the retry timer.
