Collect the CM status from all the nodes and ensure they are authenticatedStep 6. the Cisco TAC. Step1: Open CUCM CLI via Putty. Definition: the connection is being established c. Dropped i. Queue: Continuously rising / accumulating ii. In case you reach the Cisco TAC for further assistance, ensure If there are any errors in the components, the errors will be Customers Also Viewed These Support Documents. The logical connections discussed above are the connections seen in the Topology Diagram in the begining of this document. Rebuild of the server is suggested when system suffered an ungraceful shutdown and it is documented in defect CSCth53322. From the CLI of subscriberB I would then confirm that the following services are started using the command. Execute the utils dbreplication stop command on all subscribers. The Steps 7 and 8 must be performed after the checklist is New here? Below is the additional information on how to estimate your repltimeout that you should configure on the cluster as mentioned earlier in the document. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Check the same and use the Timestamp. A setup failure might have occurred ifreplication is in this Set up is still in progress. Thanks for taking the time to put it together. The Cisco Unified Reporting CM Database Report (Refer to Step 2). This error is caused when one or more nodes in the cluster have Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website.

Once an accurate replication status is displayed, check the All Rights Reserved. particular node: utils dbreplication stop (Only on the publisher), utils dbreplcation dropadmindb (Only on the affected Minutes.Commands to check/set the replication timeout: show tech repltimeout ( To check the current replication timeout g_# with the number being the node id. If the intra-cluster communication is broken, database Wait for it to complete before you start the next step. In RTMT, Choose CallManager->Service->Database Summary. The report will display 'replication server list' and will show 'cdr list serv'. Ensure that the port number 1515 is allowed on the network. Servers here should have the correct hostname and node id (populated from the process node table). Please refer to the below screenshot. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes). My go-to when troubleshooting database replication. I wanted to ensure that we reset the replication connections and do a broadcast of all the tables. connectivity with all the nodesin the cluster. 4 SetupFailed/DroppedServer no longer has an active logical "REPLICATION STATUS": This lets you know if the node is connected or offlineiii. 03-19-2019 Run the utils dbreplication runtimestate command to check the status again. Necessary cookies are absolutely essential for the website to function properly. However, Unified CM Database Status Report also displays this information as shown in the image. whether the tables match. 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). Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery, Step 6. Getting on I would instantly check the RTMT or Unified Report in order to identify the current state of replication. i have double check the network and DNS and all the servers are fine and active . Generate a new report and check if the Rhost files are Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery. with the reference clock. This is similar to the server being in state 4. The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. 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. This file is used to locally resolve hostnames to IP addresses. Database replication can be damaged due to ungraceful shutdowns and they are visible in System-history log. To monitor the process, run the RTMT/utils dbreplication 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. In order to determine whether your database replication is Ensure Local and Publisher databases are accessible. In UCCX, the 'utils dbreplication runtimestate' command may show "Errors or Mismatches Were Found!! 08:29 AM The publisher is in Replication State = 3, All subscribers in the cluster are in Replication State = 4. Set up is still in progress. set new default gateway: . Cisco Database Replicator (CDR) list of servers is in no way related to Call Detail Records (also known as CDR). Ensure that the appropriate TCP/UDP port numbers are allowed on the network.

Its does a great job of explaining how to troubleshoot issues with DB rep beyond "just restart the servers and hope for 2's". Multi-Language Call Routing Unity Connection. - edited necessary to troubleshoot and resolve those issues. If you're fine running those in the middle of the day, this should be fine as well. Verify if the A CiscoDB service is running from the CLI DBver& REPL. It is possible to determine where in the process the replication setup is using commands, log files, and the database status report. Server 1-5 = 1 Minute Per ServerServers 6-10 = 2 Minutes Per Refer to the sequence to reset the database replication and start the process from scratch. message, check your network forany retransmissions or block the For IM and Presence Service , enter the command on the database publisher node if you have more than one node in your deployment. If the intra-cluster communication is broken, database replication issues occur. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Thanks, if I do a manual back up I reserve it for early morning activity. Ensure that: The nodes are in the same Data Center/Site: All the nodes are I choose to ask for the Database Status report as the customer is in a version that has this available. In 6.x and 7.x all servers could show state 3 if one server is down in the cluster. database status from the Cisco Unified Reporting page on the flagged as anerror. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Reset the database replication from the scratch. After you complete Step 4, if there are no issues reported, run If some nodes are not able to join the replication process, increase the parameter to a higher value as shown. At the publisher server, issue the utils dbreplication reset all. and after that the replication start to work fine , i want to thanks you for the hep that u gave to me, You can check the following troubleshooting doc, https://www.cisco.com/c/en/us/support/docs/unified-communications/unity-connection/116942-technote-uc-00.html. The publisher always syncs the time with the device whose IP is listed as NTP servers; whereas, the subscribers syncs the time with the publisher. Timestamp. network connectivity and the securitypassword is same on all the Here is an important bug which affects 8.6 , 9.1 and 10.0 cucm versions, https://tools.cisco.com/bugsearch/bug/CSCul13413/?reffering_site=dumpcr. This is very helpful information. 03-12-2019 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. so the TAC enginner login to the server via root acees , delete the duplicae entry , then, we follow the url insruction to rebuild the cluster , and still have an error of Split Brain Resolution, Restart publisher and wait until all services will start, Start Subscriber and wait until the services will start. 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". If the RPC hello does not work for a particular node: - Ensure the network connectivity between the particular node the nodes. Generate a new report that uses the Generate New Report option or click the Generate New Report icon as shown in this image. The replication timeout is based on the number of nodes in the On the Publisher, enter the utils dbreplication stop command. A setup failure can occur if replication is in this state for more than an hour. Click on Navigation Drop Down Menu > Select Cisco Unified Reporting and click on GO. The show network cluster command checksfor There is a possibility of an incorrect activity when an IP The show network clustercommand checks for authentication of all nodes. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. You may get what you are looking for, or you might not. Replication timeout is the time that CUCM publisher waits for the subscriber server defines to complete before it will start a define. Try to sync the local servers first. "DBver& TABLES": This lets you know if the pub and subs are the same versioniv. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Ensure Replication Server List (cdr list serv) is populated for Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. This is used to determine to which servers replicates are pushed. this image. It is more like a push model than a pull model. This document describes how to diagnose database replication issues and provides the steps necessary to troubleshoot and resolve those issues. Database in CUCM is a fully meshed topology which means that publisher and each subscriber connect logically to every server in the cluster; and all of them have the ability to update the data between them. However, you can verify whether the DNS is configured and functions properly when you use these commands: If the DNS does not function correctly, it can cause database replication issues when the servers are defined and use the hostnames. DBver& REPL. Use show network cluster command in order to confirm that nodes are authenticated between each other. 3. case of an unsuccessfulconnection, go to Step 8. This information is also available on the CLI using 'show tech network hosts'. whether there is an updateto the User Facing Feature (UFF) that has hostnames. node. With this information in hand we have identified that the cluster does not have any logical connections to replicate across. nodes. Ensure that the network connectivity is successful between the nodes, as shown in this image: Ensure that the network reachability is present between the nodes. 5.x, it indicates that the setup is still in progress. 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. The following table lists each command and it's function. I'll run in before the rooster wakes. Recommended to set to 40 for large clusters (10+ nodes). This can be used as a helpful tool to see which tables are replicating in the process. Communications Manager 5.x has a similar replication topology to Callmanager 4.X. 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. 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. 03-16-2019 utils dbreplication runtimestate. The full list of user facing features is located on the following slide. not been passed from the subscriber to theother device in the - edited Cisco recommends that you have knowledge of these topics: The information in this document is based on these software versions: The information in this document was created from the devices in a specific lab environment. 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. Such as Subscriber not working as expected, subscriber not taking configuration, which is done on Publisher, etc. They both follow a hub and spoke topology. Thanks a lot for this easy-to-understand and highly useful guide!! Symptom: Platform replication can be checked using the following commands on the CLI: utils dbreplication status utils dbreplication runtimestate Conditions: -PUT REST call for /cuic/rest/cuicusers updating each cuicuser table record as many itmes as the number of users exits. Cisco TAC. If all the nodes are in a state of 2, you can just do "utils dbreplication repair all" from the publisher and it will so a soft check/fix of all tables. further to troubleshoot. Great guide! 10:20 AM. Communications Manager (CUCM) publisher, as shown inthis image. Ensure that the network connectivity is successful between the We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. New here? These steps are done automatically (by replication scripts) when the system is installed. If yes, go toStep 8. If this fails, contact the Steps to Diagnose the Database Replication, Step 1. 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. Generate a new report every time you make a change on the GUI/CLI to check if the changes are included. In 5.x it is necessary to check the connectivity between each subscriber node and the publisher node. Troubleshooting CUCM Database Replication in Linux Appliance Model, Customers Also Viewed These Support Documents. still in progress.
