A setup failure might have occurred ifreplication is in this In case of an unsuccessful connection, go to Step 8. We now do some other checks to prepare to fix replication. (ID) & STATUS QUEUE TABLES LOOP? The documentation set for this product strives to use bias-free language. 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. To verify the database replication, run the utils dbreplication the Sqlhosts files are mismatched, run the command from, http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/10_0_1/ipchange/CUCM_BK_C3782AAB_00_change-ipaddress-hostname-100/CUCM_BK_C3782AAB_00_change-ipaddress-hostname-100_chapter_011.html, Generate a new report and check if the Sqlhost files are IDS replication is configured so that each server is a "root" node in the replication network. CUCMStep 3. Review the Unified CM Database Report any component As shown in this image, the Unified CM Hosts, the Rhosts and the Sqlhosts are equivalent on all the nodes. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. We also no longer wait for the total repltimeout when we know all the nodes have defined. After you complete Step 4, if there are no issues reported, run whether the tables match. Proceed to Step 8, if the status does not change. This state is rarely seen in versions 6.x and 7.x; in versi. .tar file using a SFTPserver. Following this command 'utils dbreplication reset all' should be run in order to get correct status information. Stops currently replication running, restarts A Cisco DB Replicator, deletes marker file used to signal replication to begin. The common error messages as seen in the network connectivity tests: 1. database replicationStep 8. (2) Execute the utils dbreplication stop command on the Publisher.

Ensure that the network connectivity is successful between the It is important to verify the state of replication that is being provided by any of these 3 methods. Thus, the only way for a change made on a particular server to get to other servers is for that server to replicate it personally. needs to be opened. 09:32 AM. Being in this state for a period longer than an hour could indicate a failure in setup. This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. When we do a utils dbreplication reset all they get done again. In order to verify database status in CUCM, access from Command Line Interface (CLI) must be granded in each of the nodes in the cluster. The utils dbreplication runtimestate command shows out of sync or scratch. Choose "Cisco Unified Reporting" from the Navigation dropdown in the upper right corner of the CCMAdministration page. nodes are not able to join the replicationprocess, increase the It is more like a push model than a pull model.

There are three important files associated to the database and they must be the same in each of the nodes involved. Reset the database replication from scratch, Unified Communications Manager (CallManager). equivalent on all the nodes. Verify database replication is broken. Great articleappreciate your hard work on this stuff ! Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are equivalent on all the nodes. In 6.x and later, because of the fully meshed topology, it is necessary to check replication between every node in the cluster. There is a possibility of an incorrect activity when an IP address changes or updates to the Hostname on the server. Restart these services from the CLI of the publisher server and check if the mismatch is cleared. is broken, and provides thetroubleshoot methodology that a TAC Server Servers >10 = 3 Minutes PerServer. set new default gateway: . In case errors are visible when these parameters are validated, it is suggested to contact Cisco Technical Assistance Center (TAC) and provide the collected information from each node in the cluster for further assistance. 1) Login to Primary Node and issue command: >> utils system restart 2) Wait for the server to come up, if you can open Web interface, service is fully functional. high, check network performance. There are several commands which can be used so it is important to use the correct command under the correct circumstance. Model, Step 2. Collect the CM database status from the Cisco Unified Remove database replication (utils uccx dbreplication teardown) Setup database replication (utils uccx dbreplication setup) Initiate a data repair process for all the databases (utils uccx dbreplication repair all). However, you can verifywhether the DNS is configured and network intensive task as it pushesthe actual tables to all the Symptom: utils dbreplication runtimestate shows the replication is setup completed but with RTMT counter value as zero. This section describes scenarios in which database replication is broken and provides the troubleshoot methodology that a TAC engineer follows in order to diagnose and isolate the problem.

If only the Rhosts files are mismatched, run the commands from the CLI: Generate a new report and check if the Rhost files are equivalent on all the servers. - edited Checkes critical dynamic tables for consistency. Replication is in the process of setting up. Confirm the connectivity between nodes. This error is caused when one or more nodes in the cluster have a network connectivity problem. Publisher must be able to reach all subscribers and network connectivity result must be completed successfully. Since the subscriber's database is read only and the publisher's database is inaccessible, no changes are permitted to the database during the failover period. Steps to Diagnose the Database Replication. hello is successful, asshown in this image. start the process from the scratch.

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 clusters with 5 nodes or less, the default repltimeout configuration of 300s is optimal. Check the same and use the Timestamp.

I have check the system and all networking is fine , the server are fine . If there is an issue with connectivity, an error is often displayed on the Domain Name Server/Reverse Domain Name Server (DNS/RDNS). Clustering over WAN (CoW) long delays can cause the data sync process to be exponentially longer. To monitor the process, run the RTMT/utils dbreplication runtimestate command. You can also look in the informix log on that box to confirm this. Calculate the replication timeout based on the number of nodes in the cluster. If any errors/mismatches are discovered, theyare shown Repair all/selective the tables for database Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. not been passed from the subscriber to theother device in the Set up is still in progress. Overall replication setup time is improved, although It still comes into play during a node down and upgrade scenarios when node reboots are spread out over time. image. It is extremely important for the NTP to be fully functional in order to avoid any database replication issues. - Ensure that the port number 1515 is allowed on the status again.

TAC engineer on a replication issue case referred me to this link as a helpful education resource. Database replication can be damaged due to ungraceful shutdowns and they are visible in System-history log. All of the devices used in this document started with a cleared (default) configuration. If the network connectivity fails for the nodes: Generate a new report, and check for a successful connection. still in progress. Run the utils dbreplication runtimestate command to check the status again. connectivity with all the nodesin the cluster. In 7.1.2 and later utils dbreplication stop all can be run on the Publisher node to stop replication on all nodes, Always run from the publisher node, used to reset replication connections and do a broadcast of all tables. Replication in Communications Manager 6.x, 7.x, and 8.x is no longer a hub and spoke topology but is a fully meshed topology as seen in the figure below. network connectivity and the securitypassword is same on all the Check the connectivity status from all the nodes and ensure they are authenticated, Step 6.
