If the A Cisco DB service is down, run the utils service start A This error is caused when the reverse DNS lookup fails on a node. You may get what you are looking for, or you might not. There are 5 states. 3. Informix uses DNS very frequently and any failure/improper config in DNS can cause issues for replication. Refer to the sequence to reset the database replication and NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER. Set up is still in progress. 2. is broken, and provides thetroubleshoot methodology that a TAC 03-12-2019 equivalent on all the servers. Communications Manager 5.x has a similar replication topology to Callmanager 4.X. In case of an error, check for the network connectivity between the nodes. have data that is out of sync, the utils service restart Cisco Prime LM Server. 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". Steps to Diagnose the Database Replication, Step 1. We now do some other checks to prepare to fix replication. In case of an unsuccessful connection, go to Step 8. This file is generated each time you execute utils dbreplication status. the Cisco TAC. replication. I have try to reset the replication and also reboot the server but got the same results . Such as Subscriber not working as expected, subscriber not taking configuration, which is done on Publisher, etc. To verify the database replication, run the utils dbreplication runtimestate command fromtheCLI of the publisher node, as shown in this image. Model, Step 2. testcommand. The documentation on checking connectivity is linked below. If the RPC hello does not work for a particular node: - Ensure the network connectivity between the particular node Once it is generated and downloaded, save the report so that it can be provided to a TAC engineer in case a service request (SR) needs to be opened. database replicationStep 8. Check the individual components using 10-25-2010 The show network clustercommand checks for authentication of all nodes. Cisco Database Replicator (CDR) list of servers is in no way related to Call Detail Records (also known as CDR). We verify in the report that all of the hosts files look correct. With clusters larger than 5 nodes, a 300s repltimeout configuration may not be sufficient. Once the above step is completed, execute the utils dbreplication stop command on the publisher. PING REPLICATION REPL. reachable with a lower RoundTrip Time (RTT). Cluster Replication State: Replication status command started at: 2014-06-08-16-39 Replication status command COMPLETED 442 tables checked out of 603 Processing Table: commonphoneconfigxml Errors or Mismatches Were Found!!! 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.

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. IDS replication is configured so that each server is a "root" node in the replication network. No replication is occurring in this state. Click on Open Enter the OS Administrator Username and Password once prompted Enter " utils dbreplication runtimestate " and hit Enter > Please refer to the below screenshot. This command can be run on all subscribers at the same time but needs to complete on all subscribers prior to being run on the publisher. 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. Thanks for taking the time to put it together. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. All the nodes have the connectivity to each other. how can customer recreate it? Thanks for creating this Patrick. Full list of CCM servers for replication. Complete these steps in order to check NTP status: 2. 2). Replication is continuous. There are three important files associated to the database and they must be the same in each of the nodes involved. DBver& REPL. Tool (RTMT) for the replication. If there are any errors in the components, the errors will be Verify database replication is broken, Step 2. parent reference clock) must be less. https://supportforums.cisco.com/t5/collaboration-voice-and-video/rtmt/ba-p/3102764. of sync ornot requested statuses. 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. Status as shown in this image. Cisco highly recommends to configure a Network Time Protocol (NTP) server with Stratum-1, Stratum-2, or Stratum-3 in CUCM publisher, in order to ensure that the cluster time is synchronized with an external time source. In the report the information I find is the following. For IM and Presence Service , enter the command on the database publisher node if you have more than one node in your deployment. Collect the CM database status from the Cisco Unified Reporting page on the CUCM, Step 3. Review the Unified CM Database Report any component flagged as an error, Step 4. CUCMStep 3. Review the Unified CM Database Report any component The documentation set for this product strives to use bias-free language. Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery, Step 6. The following table lists each command and it's function. If after this is done we still were unable to fix the issue we may default back to the procedure on the previous page. nodes. Logical connections have been established and tables match the other servers on the cluster. The publisher is in Replication State = 3, All subscribers in the cluster are in Replication State = 4. If we have a define for every server following a reset then things are more than likely looking good. A setup failure might have occurred ifreplication is in this This document discusses the basics needed to effectively troubleshoot and resolve replication issues. In the output, ensure that the Cluster Replication State does connectivity with all the nodesin the cluster. Available in 7.X and later this command shows the state of replication as well as the state of replication repairs and resets. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes). present), utils network host - Checks for resolution of ip The most important components for database replication functionality are validate_network, ntp_reachability,and ntp_stratum. - edited admin:utils dbreplication runtimestate. Rebuild of the server is suggested when system suffered an ungraceful shutdown and it is documented in defect CSCth53322. 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). In case of an error, check for the network connectivity between and the publisher. It is extremely important for the NTP to be fully functional in order to avoid any database replication issues. This section describes scenarios in which database replication Database replication commands must be run from the publisher. Your email address will not be published. Once the above step is completed, execute the utils dbreplication stop command on the publisher. Navigate to System Reports and click Unified CM Database 3. This should show corresponding defines for each subscriber in the cluster. 2. If any errors/mismatches are discovered, they are shown in the output and the RTMT state changes accordingly, 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. Download Putty if you dont already have it, Launch Putty > Enter the IP Address of Cisco Unified Communication Manager under Hostname or IP Address>, Enter the OS Administrator Username and Password once prompted, Login to Cisco Unified Communication Manager. (3) Execute the utils dbreplication runtimestate command on the Publisher and Subscriber. "REPL. Set up is still in progress. How many servers do you have in the cluster ? Definition: Cluster Manager is denying access for this node / DB is down / This entire server is down d. Disconnect i. Queue: Continuously rising / accumulating ii. In We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. We'll assume you're ok with this, but you can opt-out if you wish. Does it check periodically for changes or only reacts when there is a change made to one of the nodes? Ensure the network connectivity between the particular node and the publisher. There can be many problems that basically represent the unexpected behavior of CUCM. Execute the utils dbreplication stop command on all subscribers. But, "B" will not send that same change on to "C". This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. that the nodes havenetwork connecitivty well under 80 ms. Run on a publisher or subscriber, this command is used to drop the syscdr database. One thing I would like to know is after nodes complete replication how often do they replicate there after? An excellent and comprehensive DB replication guide! Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Run this command when RTMT = 2, not when RTMT = 0 or 3. If any errors/mismatches are discovered, theyare shown If the Rhosts files are mismatched along with the host files, After you complete Step4, if there are no issues reported, run the. Check the connectivity engineer follows in order to diagnose and isolate theproblem. If the utils dbreplication runtimestate command shows that there However, Unified CM Database Status Report also displays this information as shown in the image. needs to be opened. Error, Intra-cluster communication is broken, as shown in this image. Verify database replication is broken. start the process from the scratch. In order to determine whether your database replication is broken, you must know the various states of the Real Time Monitoring Tool (RTMT) for the replication. Example: 12 Servers in In 6.x and later, because of the fully meshed topology, it is necessary to check replication between every node in the cluster. Based on the version of CUCM in use you may see the following: i. Execute the utils dbreplication stop command on all subscribers. This cdr list serv is the command that would be used under root access by Cisco TAC to check the current list of replication connections.
