Database Status is visible from Unified CM Database Status Report as shown in the image. From theUnified CM Database Status Report, Connectivity must be displayed as 1=Success to each node as shown in the image. These services must be displayed as STARTED. one server is down in the cluster. 5.x, it indicates that the setup is still in progress. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. Step 7. This clears out configuration information from the syscdr database which forces the replicator to reread the configuration files. Collect the CM flagged as anerror. Proceed to Step 8, if the status does not change. Your email address will not be published. In versions 6.x and 7.x, all servers could show state 3 even if one server is down in the cluster. Generate a new report using the Generate New Report option or .tar file using a SFTPserver. This should occur within a few minutes of the reset. in the output and the RTMT state changes accordingly, as shown in In 5.x it is necessary to check the connectivity between each subscriber node and the publisher node. It runs a repair process on all tables in the replication for all servers that are included in the command. 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. If your network is live, ensure that you understand the potential impact of any command. 2). "REPL. Reporting pageon the CUCM. utils dbreplication stop all (Only on the publisher), utils dbreplication dropadmindb (First on all the subscribers Complete these steps in order to check NTP status: Use the utils diagnose test command to check the output, as This error is caused when the reverse DNS lookup fails on a Lets begin by documenting the places that you could check to see the replication state. 3. Note: This command is no longer functional as of CUCM 9.0(1). Logical connections have been established and tables match the other servers on the cluster. runtimestate command. Ensure the Local and the Publisher databases are accessible. 2. 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. 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. Verify database replication is brokenStep 2. If the Sqlhosts are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. message, check your network forany retransmissions or block the Define Pub - Set it up to start replicating, Define template on pub and realize it (Tells pub which tables to replicate), Realize Template on Each Sub (Tells sub which tables they will get/send data for), Sync data using "cdr check" or "cdr sync" (older systems use sync). Saved me hours of extra work. If yes, go to Step 8. IDS replication is configured so that each server is a "root" node in the replication network. Verify database replication is broken, Step 2. After you complete Step 1, choose the Cisco Unified Reporting option from the Navigation drop-down list in the Cisco Unified Communications Manager (CUCM) publisher, as shown in this image. 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. nd check if the mismatch is cleared. 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. 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. Use "utils dbreplication reset all" instead. 5. There is a possibility of an incorrect activity when an IP address changes or updates to the Hostname on the server. Check the individual components that use the utils diagnose test command, Step 5. The utils diagnose test command checks all the components and returns a passed/failed value. The output from the publisher contains processnode table entries. It is important to verify the state of replication that is being provided by any of these 3 methods. It is important to understand that the database replication is a The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. 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. those issues. This command only triggers the check of the dabatase status. Starting in CUCM 10.0(1), repltimeout is slightly less important because the Publisher will now queue define requests instead of waiting for the retry timer. Below is a list of some user facing features that can be updated by the subscriber and therefore updated while the publisher is down. Steps to Diagnose the Database Replication. nodes, as shown in this image: If the network connectivty fails for the nodes: - Ensure that the network reachability is present between the It is mandatory to procure user consent prior to running these cookies on your website. 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. flagged with a red cross icon, asshown in this image. You could probably pull the following and see if you find anything. Run this command when RTMT = 2, not when RTMT = 0 or 3. New here? Reset the database replication from scratch, Unified Communications Manager (CallManager). i have try also to reboot all the servers but still get the same results . not requested statusesStep 7. Refer to the sequence to reset the database replication and If no, contact Cisco TAC. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are This state is rarely seen in Very detailed. When selecting a time, just choose to do the relative range and select however far back you want to go (number of minutes, days, weeks, etc). Step1: Open CUCM CLI via Putty. Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. g_# with the number being the node id. Refer to this link in order to change IP address to the Hostname for the CUCM. 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. Database replication commands must be run from the publisher. Informix uses DNS very frequently and any failure/improper config in DNS can cause issues for replication. Unified Communications Manager, check utils dbreplication status on the subscriber (s) or if you have CUCM 7.1.5 check utils dbreplication runtimestate. It depends on the environment. cluster: The replication timeout(Default: 300 Seconds) is the time For the image above we see the last action was a BROADCAST SYNC and the date of the action was 2015/09/27 at 11:34 in the morning. Then choose "Database Status Report", and generate a new report. 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. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Generate a new report and check if the Rhost files are i have open a TAC case and we have found that there are a. ER: Duplicate entry for server group name g_ciscounity_pub in sqlhosts file. The output from CUCM version 10.5.2 NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER The explanation replication issues occur. Cisco Unified Communications Manager (CallManager), View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices. 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. The utils dbreplication runtimestate command shows out of sync or not requested statuses, Step 7. All the nodes have the connectivity to each other. PING REPLICATION REPL. Thus the recommendation to the customer would be to follow the most basic process that fixes about 50 percent of replication cases. 06-08-2014 This file is used to locally resolve hostnames to IP addresses. 1: This lets you know the last action performed and the time of the action. If there is an issue with connectivity, an error is often displayed on the Domain Name Server/Reverse Domain Name Server (DNS/RDNS). Consult the Cisco TAC before proceeding with Step 7 and 8 in Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Communications Manager (CUCM) publisher, as shown inthis image. If any node has a state other than 2, continue to troubleshoot. Timestamp. These cookies do not store any personal information. That would be covered under the "utils diagnose test" section. Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. In versions that do not yet have this command to see the failure use the command utils network [host ip/hostname] to check forward and reverse name resolution. Each subscriber must reach Publisher and other subscribers included in the cluster network connectivity result must be completed successfully. Error checking is ignored.

This category only includes cookies that ensures basic functionalities and security features of the website. Refer to Step 2- Check the services by running the command "utils service list" 3- Run the command and get the output of "utils diagnose test" and see if it fails at any point 4- Run a test for other nodes using "utils network connectivity" on all the nodes Set up is still in progress. Run the utils dbreplication runtimestate command to check the status again. You can also look in the informix log on that box to confirm this. !" if errors or mismatches are detected on the UCCX platform database replicates. It is extremely important for the NTP to be fully functional in equivalent on all the servers. Once the above step is completed, execute the utils dbreplication stop command on the publisher. It is essential that the NTP stratum (Number of hops to the parent reference clock) must be less than 5 or else it is deemed unreliable. Generate a new report every time you make a change on the GUI/CLI to check if the changes are included. a network connectivity problem.Ensure that all the nodes have ping Required fields are marked *.
