Model, Step 2. Ensure that both servers are RPC reachable column = YES). Logical connections are established and the tables are matched with the other se, Logical connections are established but there is an unsurety whether the tables m, In versions 6.x and 7.x, all servers could show state 3 even if one server is down, This issue can occur because the other servers are unsure whether there is an up, to the User Facing Feature (UFF) that has not been passed from the subscriber to, Server no longer has an active logical connection in order to receive any database. Refer to this link for details on TCP/UDP port usage: Cisco Unified Communications Manager TCP and UDP port usage. This file is generated each time you execute utils dbreplication status. on the network. This state is rarely seen in versions 6.x and 7.x; in version 5.x, it indicates that the setup is still in progress. For database replication, connectivity between servers must be established properly in each of the nodes involved in the cluster. Following this command 'utils dbreplication reset all' should be run in order to get correct status information. If no, contact Cisco TAC. The utils dbreplication runtimestate command shows out !" if errors or mismatches are detected on the UCCX platform database replicates. Try to sync the local servers first. This file is used to locally resolve hostnames to IP addresses. 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. All rights reserved. But, "B" will not send that same change on to "C". Note: Allow all the tables to be checked and then proceed The publisher is in Replication State = 3, SubscriberA is in Replication State =3 and SubscriberB is in Replication State = 4. If yes, go to Step 8. utils dbreplication repair -- in CUCM 5.x, this command meant a reset of the replication, whereas, in CUCM 6.10 and higher versions, this means a repair of the data. The common error the proper functioning of the database replication are: The validate_network command checks all aspects of the network Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. thesubscribers syncs the time with the publisher. Definition: Replication is down on the target server. In the output, ensure that the Cluster Replication State does not contain the old sync information. 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. 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. Step 8. That has slowed me down fixing some DB replication issues. If yes, go toStep 8. It depends on the environment. The following table lists each command and it's function. 2. reachability.

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. Verify database replication is broken, Step 2. Once the above step is completed, execute the utils dbreplication stop command on the publisher. 0 InitializationStateReplication is in the process of setting If there are errors or mismatches found, run the file view command to identify any suspect tables if that is the cause of the errors/mismatches.5: This is the database version. Refer to the sequence to reset the database replication and start the process from scratch. If the broadcast sync is not updated with a recent date, run the To monitor the process, run the RTMT/utils dbreplication Error checking is ignored. connectivity with all the nodesin the cluster. We now do some other checks to prepare to fix replication. If the Rhosts files are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. Generate a new report, and check for a successful connection. After few minutes, use the command "utils dbreplication runtimestate" to check the replication status. state for more than an hour. The cdr_broadcast actually contains which tables are being replicated and the result. UC Collabing 2023. T. 2.
