Navigate to System Reports and click Unified CM Database In order to verify its progress, use utils dbreplication runtimestate command. Status as shown in this image. nodes in the cluster. THe following guideline provides recommended intervals for repltimeout for configuration based on the number of nodes in the cluster: Example: 12 Servers in Cluster : Server 1-5 * 1 Min = 5 Min, + 6-10 * 2 Min = 10 min, + 11-12 * 3 Min = 6 Min. 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). To verify the database replication, run the utils dbreplication cluster: The replication timeout(Default: 300 Seconds) is the time This change in topology overcomes previous limitations in replication architecture, as changes can now be made to local subscriber databases for user facing faetures even while the publisher is inaccessible. state for more than an hour. Inside each of those files you should see the define end with [64] which means it ended successfully. Available in 7.X and later this command shows the state of replication as well as the state of replication repairs and resets.

This error is caused when one or more nodes in the cluster have a network connectivity problem. for the CUCM. Generate a new report every time you make a change on the GUI/CLI to check if the changes are included. Definition: Replication is down on the target server. This can happen because the other servers are unsure if there is an update to a user facing feature that has not been passed from that sub to the other device in the cluster. We now do some other checks to prepare to fix replication. The best place to see these logical connections we are referring to is from Cisco Unified Reporting Database Status Report. states of the Real Time Monitoring Tool (RTMT) for the replication. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. 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. still in progress. Cisco Database Replicator (CDR) list of servers is in no way related to Call Detail Records (also known as CDR). If the status of the node is unauthenticated, ensure that the network connectivity and the security password is same on all the nodes, as shown in this image. Perform the procedure in the off business hours. This is an outdated state and is no longer around. Steps to Diagnose the Database Replication, Step 1. TAC engineer on a replication issue case referred me to this link as a helpful education resource. This is similar to the server being in state 4. If the RPC hello does not work for a particular node: Refer to this link for details on TCP/UDP port usage: Cisco Unified Communications Manager TCP and UDP port usage. After all subscribers have been defined we then wait the repltimeout (Can check from show tech repltimeout) it will then do a broadcast file that actually pushes the replicates across. Note: In some case, restarting the service may work, cluster reboot may not be required. If only Generate a new report that uses the Generate New Report option or click the Generate New Report icon as shown in this image. Based on the version of CUCM in use you may see the following: i. Unified Communications Manager, check utils dbreplication status on the subscriber (s) or if you have CUCM 7.1.5 check utils dbreplication runtimestate. In case you reach the Cisco TAC for further assistance, ensure 'utils dbreplication runtimestate' then shows the actual status of the server. Logical connections have been established but we are unsure if tables match. Cluster Detailed View from ccm125p (2 Servers): PING DB/RPC/ REPL. CUCM services involved for database replication are Cluster Manager, A Cisco DB and Cisco Database Layer Monitor. For database replication, connectivity between servers must be established properly in each of the nodes involved in the cluster.
