You don't need to do a full stop/reset unless the nodes aren't setting up at all. cluster: The replication timeout(Default: 300 Seconds) is the time There are three important files associated to the database and they must be the same in each of the nodes involved. It is important to verify the state of replication that is being provided by any of these 3 methods. issues and provides the stepsnecessary to troubleshoot and resolve This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process.

The full list of user facing features is located on the following slide. To confirm that replication is setting up in a single batch, run utils dbreplication stop all followed by utils dbreplication reset all from the CUCM publisher, and then verify the sequence of logs using file list activelog cm/trace/dbl/* date detailed from the publisher CLI. 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 If The most important components for database replication functionality are validate_network, ntp_reachability,and ntp_stratum. If the intra-cluster communication is broken, database replication issues occur. Run this command when RTMT = 2, not when RTMT = 0 or 3. The Cisco Unified Reporting CM Database Report (Refer to Step 2). Complete these steps in order to check NTP status: 2. The best command to verify DNS is utils diagnose test. Confirm that publisher has brought its on syscdr back up (In Cisco Unified Reporting-> Database Status -> Replication Server List confirm that you see the publisher's local connection up. This issue can occur because the other servers are unsure 10:20 AM. Ensure that the port number 1515 is allowed on the network.

Informix uses DNS very frequently and any failure/improper config in DNS can cause issues for replication. 07:42 AM On the right hand side of the screen, the replication status will be shown. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Below is the /etc/hosts as displayed Verified in Unified Reporting. Perform the procedure in the off business hours. hello is successful, asshown in this image. Based on the version of CUCM in use you may see the following: i.

A setup failure might have occurred ifreplication is in this Cluster : Server 1-5 * 1 min = 5 min, + 6-10 * 2 min = 10 min, New here? It is important to understand that the database replication is a network intensive task as it pushes the actual tables to all the nodes in the cluster. Ensure that the Database Layer Remote Procedural Call (DBL RPC) After you complete Step 4, if there are no issues reported, run 2. 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. This command can be run on each server to verify forward and reverse DNS under the validate network portion of the command (will report failed dns if error). CUCMStep 3. Review the Unified CM Database Report any component Repair all/selective tables for database replication, Step 8. To verify the database replication, run the utils dbreplication Finally after that has returned to state 2 all subs in the cluster must be rebooted. 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. i have try also to reboot all the servers but still get the same results . TCP/UDP ports. Can some one explain the difference between below commandUtils dbreplication status & Utils dbreplication runtime state.

Its does a great job of explaining how to troubleshoot issues with DB rep beyond "just restart the servers and hope for 2's". If the A Cisco DB service is down, run the utils service start A One thing I would like to know is after nodes complete replication how often do they replicate there after? This is important to keep in mind if an upgrade has taken place from 5.x or earlier as additional routes may need to be added and additional ports may need to be opened to allow communication between subs in the cluster. - edited Last modified October 10, 2018, Your email address will not be published. 4. utils dbreplication stop all (Only on the publisher), utils dbreplication dropadmindb (First on all the subscribers replication issues occur. That has slowed me down fixing some DB replication issues. I have Question, If the .rhost file is deleted/corrputed, is there a way to recreate it? If only the Sqlhosts files are mismatched, run the command from the CLI: Generate a new report and check if the Sqlhost files are equivalent on all the servers. Cisco DB command to startthe service. 2). 1: This lets you know the last action performed and the time of the action. 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. with connectivity, an error is often displayed on the DomainName If the statusof the node is unauthenticated, ensure that the In the output, ensure that the Cluster Replication State does not contain the old sync information. Wait for it to complete before you start the next step. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. Run the utils dbreplication runtimestate command to check the (3) Execute the utils dbreplication runtimestate command on the Publisher and Subscriber. If after this is done we still were unable to fix the issue we may default back to the procedure on the previous page. This document discusses the basics needed to effectively troubleshoot and resolve replication issues. flagged as an errorStep 4. Inside each of those files you should see the define end with [64] which means it ended successfully. Later examples talk about identifying a corrupt syscdr database. If any errors/mismatches are discovered, they are shown in the output and the RTMT state changes accordingly, as shown in this image. Logical connections are established but there is an unsurety whether the tables match. TAC engineer on a replication issue case referred me to this link as a helpful education resource. Confirm the connectivity between nodes. 1: This lets you know the last action performed and the time of the action. The validate_network than 5 or else it will deem it unreliable. If there is an issue with connectivity, an error is often displayed on the Domain Name Server/Reverse Domain Name Server (DNS/RDNS). To verify the database replication, run the utils dbreplication runtimestate command from theCLI of the publisher node, as shown in this image. Cisco Unity Connection Replication not setup. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Refer to this link in order to change IP address to the Hostname Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). CUCM Database Replication is an area in which Cisco customers and partners have asked for more in-depth training in being able to properly assess a replication problem and potentially resolve an issue without involving TAC. Then choose "Database Status Report", and generate a new report. Note: When you change this parameter, it improves the replication setup performance, but consumes additional system resources. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. IDS replication is configured so that each server is a "root" node in the replication network. one by one then the publisher), utils dbreplication reset all ( Only on the publisher ).
