It is important to understand that the database replication is a This is very helpful information. status again. 03-16-2019 4. Same as above, but may need to be used in cases where above command fails. This is an important step. Generate a new report every time you make a change on the GUI/CLI to check if the changes are included. . 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. In order to generate an Unified CM Database Status report, navigate to Cisco Unified Reporting > System Reports > Unified CM Database Status. You must check the status for every node. value ), utils dbreplication setrepltimeout ( To set the replication Replication timeout is the time that CUCM publisher waits for the subscriber server defines to complete before it will start a define. If there are any errors in the components, the errors will be Step2: Put the command "utils dbreplication runtimestate". Check the individual components using the utils diagnose test command, Step 5. Ensure that the network connectivity is successful between the 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. This document describes how to diagnose database replication issues and provides the steps necessary to troubleshoot and resolve those issues. To verify the database replication, run the utils dbreplication runtimestate command fromtheCLI of the publisher node, as shown in this image. database status from the Cisco Unified Reporting page on the network. If yes, go toStep 8. Normally run on a subscriber. This error is caused when the reverse DNS lookup fails on a node. If this fails, contact the To verify the database replication, run the utils dbreplication Refer to the sequence to reset the database replication for a particular node: In case you reach Cisco TAC for further assistance, ensure that these outputs and the reports are provided: For further information refer to the links: Understanding the output of utils dbreplication runtimestate for CUCM, Troubleshooting CUCM Database Replication Linux Appliance Model. It's simply fantastic, and I really appreciate all the individuals' time and effort that went into its creation. 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. Navigate to System Reports and click Unified CM Database The nodes are scattered over the Wide Area Network (WAN): Ensure that the nodes have network connectivity well under 80 ms. 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. The utils create report database command from CLI. Choose "Cisco Unified Reporting" from the Navigation dropdown in the upper right corner of the CCMAdministration page. We now do some other checks to prepare to fix replication. Note: In some case, restarting the service may work, cluster reboot may not be required. This state is rarely seen in versions 6.x and 7.x; in versi. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. whether there is an updateto the User Facing Feature (UFF) that has We verify in the report that all of the hosts files look correct. for the CUCM. The amount of time this command takes to return is based on your cluster's repltimeout. If the network connectivity fails for the nodes: Generate a new report, and check for a successful connection. in the output and the RTMT state changes accordingly, as shown in One thing I would like to know is after nodes complete replication how often do they replicate there after? 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. how can customer recreate it? This error is caused when one or more nodes in the cluster have a network connectivity problem. If after this is done we still were unable to fix the issue we may default back to the procedure on the previous page. Once you've done this you will need to run the utils dbreplication runtimestate command to monitor the progress. than 5 or else it will deem it unreliable. Split Brain Resolution and some Drops of the Server . Once that command is COMPLETED, outputs can be verified and it shows the current database status. Thanks for the quick response.

Available in 7.X and later this command shows the state of replication as well as the state of replication repairs and resets. These commands allow you to know the status of each of them. utils dbreplication repair -- in CUCM 5.x, this command meant a reset of the replication, whereas, in CUCM 6.x and higher versions, this means a repair of the data. 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 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. - edited Find answers to your questions by entering keywords or phrases in the Search bar above. In order to verify them from CLI, root access is required. There are 5 states. Check the same and use the Timestamp. If the RTT is unusally 0 InitializationStateReplication is in the process of setting 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. These services must be displayed as STARTED. ensure they areauthenticated. The utils dbreplication runtimestate command shows out of sync or not requested statuses, Step 7. . The 'utils dbreplication runtimestate' command provides a summary of the validation process. Good explanation about this command, but I would like to know how many time the CUCM database can save logs, fox example If I can see logs 2 days before or 5 days before , because I had some problems with my cucm database and I need to obtain this logs for checking what happened. Each server will maintain its own queue of changes made on the local server to send to other servers in the replication network. Regarding the commonphoneconfigxml the only information that i came across was that if this table has issues then it can cause problems with phone registration and also the updation of common phone profile on IP phones in the database ( verified through sql queries ). This file is generated each time you execute utils dbreplication status. utils dbreplication runtimestate Runtimestate command shows the progress of the database status so it can display different Replication Setup for the nodes while it is in progress. one server is down in the cluster. can be provided to a TACengineer in case a service request (SR) Perform the procedure in the off business hours. If the statusof the node is unauthenticated, ensure that the 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. replication. Repair all/selective the tables for database This information is also available on the CLI using 'show tech network hosts'. functions properly using these commands: utils network eth0 all - Shows the DNS configuration (if commandcompletes the operation in 300 seconds. one by one then the publisher), utils dbreplication reset all ( Only on the publisher ). In case of an unsuccessful connection, go to Step 8. 07:42 AM The following table lists each command and it's function. those issues. 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. 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. Steps to Diagnose the Database Replication, Step 1. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. 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. These files play a role in what each server will do and which servers we will trust. Step 2. If the broadcast sync is not updated with a recent date, run the Always run from the publisher node, used to reset replication connections and do a broadcast of all the tables. 09-14-2017 is broken, and provides thetroubleshoot methodology that a TAC (RTMT) & details, ----------- ------------ ------ ---- ----------- ----- ------- ----- -----------------, PUB X.X.X.80 0.173 Yes Connected 0 match Yes (2) PUB Setup Completed, tftp1 X.X.X.81 0.259 Yes Connected 0 match Yes (2) Setup Completed, tftp2 X.X.X.82 0.203 Yes Connected 0 match Yes (2) Setup Completed, sub1 X.X.X.83 0.267 Yes Connected 0 match Yes (2) Setup Completed, sub2 X.X.X.84 0.358 Yes Connected 0 match Yes (2) Setup Completed, sub3 X.X.X.85 0.247 Yes Connected 0 match Yes (2) Setup Completed, sub4 X.X.X.86 0.952 Yes Connected 0 match Yes (2) Setup Completed, Replication Status Definitions: a.

Ensure Local and Publisher databases are accessible. This error is caused when one or more nodes in the cluster have Refer to the sequence to reset the database replication and Calculate the replication timeout based on The utils diagnose test command checks all the components and returns a passed/failed value. Communications Manager 5.x has a similar replication topology to Callmanager 4.X. Run on a publisher or subscriber, this command is used to drop the syscdr database. follow the steps mentioned under TheHosts files are mismatched. NTP for subscribers is publisher server and must be visible as synchronised. Servers here should have the correct hostname and node id (populated from the process node table). equivalent on all the servers. network utils. Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. 7: This is the ping time between the servers. 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 present), utils network host - Checks for resolution of ip Once it is generated, download and save the report so that it It runs a repair process on all tables in the replication for all servers that are included in the command. The best command to verify DNS is utils diagnose test. 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. 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.
