Step 8. Based on the version of CUCM in use you may see the following: i. Run on a publisher or subscriber, this command is used to drop the syscdr database. We'll assume you're ok with this, but you can opt-out if you wish. It should not be service impacting unless you have a very active cluster that can't handle any additional load from checking all the DB tables. This can be used as a helpful tool to see which tables are replicating in the process. I have a customer with cluster of cucm 11.5.1su2 and a a unity connection 11.5.2su2 , in the cucm everything is fine but in the unity if u type the command. Ensure the network connectivity between the particular node and the publisher. Full list of CCM servers for replication. No replication occurs in this state. This website uses cookies to improve your experience. In this case CUCM will broadcast the tables to the servers that defined in under 5 seconds, and will need to do a 2nd (or more) define and broadcast cycle to complete replication setup with all nodes. show tech network routes. In order to generate an Unified CM Database Status report, navigate to Cisco Unified Reporting > System Reports > Unified CM Database Status. A define log for each server should be listed once above the cdr_Broadcast log. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Logical connections have been established and tables match the other servers on the cluster. Thank you to each and everyone for the nominations and your support. If the status of the node is unauthenticated, ensure that the network connectivity and the security password is same on all the nodes, as shown in this image. ensure they areauthenticated. If the DNS does not functions correctly, it can cause the address changes or updates to theHostname on the server. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. The following table lists each command and it's function. 2. - edited Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! .tar file using a SFTPserver. Cisco Unity Connection Replication not setup. authentication of all nodes. It is important to understand that the database replication is a 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. that the nodes havenetwork connecitivty well under 80 ms. Check the same and use the Timestamp. Once that command is COMPLETED, outputs can be verified and it shows the current database status. Model, Step 2. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. LDAP Sync Issues. TCP/UDP ports. New here? needs to be opened. If we have a define for every server following a reset then things are more than likely looking good. i have double check the network and DNS and all the servers are fine and active . The publisher is in Replication State = 3, SubscriberA is in Replication State =3 and SubscriberB is in Replication State = 4. !" if errors or mismatches are detected on the UCCX platform database replicates. and the publisher. Network Time Protocol (NTP) Reachability: The NTP is responsible for keeping the server's time in sync After verifying that we have good connectivity and all the underlying hosts files are correct and matching across the cluster it might be necessary to use CLI replication commands to fix the replication problem. Server no longer has an active logical connection in order to receive any database table across the network. Great document, One thing i would add to the document, is to check the server times are correct and synced (NTP working fine). stateother than 2, continue to troubleshoot. T. whether the tables match. If no, contact The utils dbreplication runtimestate command shows out of sync or not requested statuses, Step 7. We also use third-party cookies that help us analyze and understand how you use this website. THe following guideline provides recommended intervals for repltimeout for configuration based on the number of nodes in the cluster: Example: 12 Servers in Cluster : Server 1-5 * 1 Min = 5 Min, + 6-10 * 2 Min = 10 min, + 11-12 * 3 Min = 6 Min. Run this command when RTMT = 2, not when RTMT = 0 or 3. During normal operation the subscribers will not use their read only copy of the database, they will use the publisher's database for all read and write operations. We now do some other checks to prepare to fix replication. This could indicate a corrupt syscdr. Once completed, follow Step 3. To check all tables run. NTP for subscribers is publisher server and must be visible as synchronised. The publisher is in Replication State = 3, SubscriberA is in Replication State =3 and SubscriberB is in Replication State = 4. nodes. As illustrated in the figure below, only the publisher's database is writable while each subscriber contains a read only database. value ), utils dbreplication setrepltimeout ( To set the replication My go-to when troubleshooting database replication. Cluster Detailed View from ccm125p (2 Servers): PING DB/RPC/ REPL. If the A Cisco DB service is down, run the utils service start A As shown in this image, the Unified , by replication states seem to be good, as i know these command but purposely i didnt execute them becz the cause here is something else. 5.x, it indicates that the setup is still in progress. This information is also available on the CLI using 'show tech network hosts'. In 6.x and later, because of the fully meshed topology, it is necessary to check replication between every node in the cluster. A. replication is in this state for more than an hour. Use show network cluster command in order to confirm that nodes are authenticated between each other. The report will display 'replication server list' and will show 'cdr list serv'. These cookies will be stored in your browser only with your consent. Step2: Put the command "utils dbreplication runtimestate". 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. That has slowed me down fixing some DB replication issues. (2) Execute the utils dbreplication stop command on the Publisher. flagged with a red cross icon, asshown in this image. Use "utils dbreplication reset all" instead. New here? In versions 6.x and 7.x, all servers could show state 3 even if one server is down in the cluster. The common error messages as seen in the network connectivity tests: 1. 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. 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. nodes in the cluster. timeout ). Error, Intra-cluster communication is broken, as shown in Step 2. how can customer recreate it? If yes, go toStep 8. 'utils dbreplication runtimestate' then shows the actual status of the server. 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. You can follow all the T-shooting links provided by Manish and I. Check the individual components using Following this command 'utils dbreplication reset all' should be run in order to get correct status information. Additionally, you can run this command: 2. You also have the option to opt-out of these cookies. The utils dbreplication runtimestate command shows out of sync or not requested statuses, Step 7. Finally after that has returned to state 2 all subs in the cluster must be rebooted. This command only triggers the check of the dabatase status. network intensive task as it pushesthe actual tables to all the utils dbreplication stop all (Only on the publisher), utils dbreplication dropadmindb (First on all the subscribers Verify database replication is brokenStep 2. 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. When we do a utils dbreplication reset all they get done again. Verify database replication is broken. 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. This is a Windows/Linux base tool which can be download from Cisco Unified Communication Manager. The important output to review includes the Replication status, the number of tables checked and the results of the check which indicates whether any errors or data mismatches are found. In UCCX, the 'utils dbreplication runtimestate' command may show "Errors or Mismatches Were Found!! Ensure the Local and the Publisher databases are accessible. If If the issue persists after trying all these steps then as suggested by Abhay you should open a TAC SR to investigate it further. Informative and detailed doc.. Easy to understand. Checkes critical dynamic tables for consistency. Error checking is ignored. A root node will not pass a replication change on to another root node. Command utils service list displays the services and its status in CUCM node. Ensure that all the nodes have ping reachability. the utils diagnose test commandStep 5. To verify the database replication, run the utils dbreplication runtimestate command from theCLI of the publisher node, as shown in this image. not been passed from the subscriber to theother device in the http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/port/8_5_1/portlist851.html, http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/port/8_0_2/portlist802.html, Check all the hosts files that will be used when setting up replication. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. Generate a new report, and check for a successful connection. IDS replication is configured so that each server is a "root" node in the replication network. versions 6.x and 7.x; in version5.x, it indicates that the setup is Rebuild of the server is suggested when system suffered an ungraceful shutdown and it is documented in defect CSCth53322. address/Hostname. Being in this state for a period longer than an hour could indicate a failure in setup. Do we require these commands ??? If yes, go to Step 8. admin:utils dbreplication runtimestate Definition: The server is up and the publisher is connected to the server b. Reporting pageon the CUCM. Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). Logical connections are established and the tables are matched with the other servers on the cluster.

The output from the publisher contains processnode table entries. broken, you must know the variousstates of the Real Time Monitoring 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. Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. 2 Replication isgoodLogical connections are established and the hello is successful, asshown in this image. If the Sqlhosts are mismatched along with the host files, follow If no, contact Cisco TAC. Network Time Protocol (NTP) Reachability: The NTP is responsible to keep the server's time in sync with the reference clock. This is likely the best summary of dbreplication I've found yet. network connectivity and the securitypassword is same on all the In case of an error, check for the network connectivity between Later examples talk about identifying a corrupt syscdr database. However, you can verifywhether the DNS is configured and This error is caused when one or more nodes in the cluster have a network connectivity problem. Step 1. 08:29 AM Required fields are marked *. 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. Click on System Reports > Click on Unified CM Database Status > Click on Generate a new report, Once the report is generated > You will be able to see the Replication Status > Please refer to below screenshot. 03-12-2019 The show network cluster command checksfor The common error their defined messages.
