If the RTT is unusually high, check network performance. Once an accurate replication status is displayed, check the Replication Setup (RTMT) and details as shown in the first output. We now do some other checks to prepare to fix replication. Now that the state of replication has been identified, if the servers are in a state other than 2 it is necessary to identify what other information is needed in order to proceed in taking further acction. If the Rhosts files are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. Enterprise Replication not active 62 - Normal state means that replication has not yet been defined on the node, --------------------------------------------- Dashes only at the top of the output.

The replication timeout is based on the number of nodes in the cluster: The replication timeout (Default: 300 Seconds) is the time that the publisher waits for all the subscribers in order to send their defined messages. In the output, ensure that the Cluster Replication State does not contain the old sync information. Very detailed. for the CUCM. I'll run in before the rooster wakes. 03-12-2019 Ensure Replication Server List (cdr list serv) is populated for all the nodes. This error is caused when one or more nodes in the cluster have Note: In some case, restarting the service may work, cluster reboot may not be required. Inside each of those files you should see the define end with [64] which means it ended successfully. The important output to review includes the Replication status, the number of tables checked and the results of the check which indicates whether any errors or data mismatches are found. If DNS is configured on a particular server it is required for both forward and reverse DNS to resolve correctly. All Rights Reserved. That has slowed me down fixing some DB replication issues. with the reference clock. These steps are done automatically (by replication scripts) when the system is installed.
