Status as shown in this image. 2. 3. The utils dbreplication runtimestate command shows out of sync or Login to Cisco Unified Communication Manager Publisher CLI via Putty > Enter the command " utils dbreplication clusterreset " and wait for the process to be completed. This enables multithreading and improves replication setup time at the slight cost of processing power. 05:50 AM This can be used as a helpful tool to see which tables are replicating in the process. Great articleappreciate your hard work on this stuff ! For example, in some instances a server could show that it is in state 3 but the 'cdr list serv' output shows that the logical connections are in "Dropped" state. How many servers do you have in the cluster ? 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. Thank you to each and everyone for the nominations and your support. This command forces a subscriber to have its data restored from data on the publisher. 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. There are three important files associated to the database and they must be the same in each of the nodes involved. Do we require these commands ??? In versions 6.x and 7.x, all servers could show state 3 even if one server is down in the cluster. image. Communications Manager (CUCM) publisher, as shown inthis image. 0.036 Yes (2) Connected 0 match Yes (2) PUB Setup CompletedSUB01DC 10.x.x.x. New here? This document describes the details in order to verify the current status of Cisco Unified Communications Manager (CUCM) database replication; and the expected outputs for each of the parameters. This state is rarely seen in versions 6.x and 7.x; in version 5.x, it indicates that the setup is still in progress. If there are any errors in the components, the errors will be Reset the database replication from the scratch Refer to the sequence to reset the database replication and start the process from the scratch. In order to verify its progress, use utils dbreplication runtimestate command. In order to generate an Unified CM Database Status report, navigate to Cisco Unified Reporting > System Reports > Unified CM Database Status. 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. set new default gateway: . flagged with a red cross icon, asshown in this image. runtimestate command. this image. one server is down in the cluster. - Ensure that the port number 1515 is allowed on the Restart these services from the CLI of the publisher server and check if the mismatch is cleared. It is mandatory to procure user consent prior to running these cookies on your website. Generate a new report and check if the Rhost files are 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. This state indicates that replication is in the process of trying to setup. Being in this state for a period longer than an hour could indicate a failure in setup. Execute the utils dbreplication stop command on all subscribers. admin:utils dbreplication runtimestate. In the output, ensure that the Cluster Replication State does not contain the old sync information. value ), utils dbreplication setrepltimeout ( To set the replication In the output, ensure that the Cluster Replication State does not contain the old sync information.Check the same using the Timestamp. Refer to the sequence to reset the database replication and After you run the command, all the tables are checked for If the Rhosts files are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. 08:29 AM 10:20 AM. Being in this state for a period longer than an hour could indicate a failure in setup. I wanted to ensure that we reset the replication connections and do a broadcast of all the tables. broken, you must know the variousstates of the Real Time Monitoring 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. That has slowed me down fixing some DB replication issues. 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. functions properly using these commands: utils network eth0 all - Shows the DNS configuration (if 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. nodes, refer to Step 8. Verify database replication is broken, Step 2. 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. If yes, go toStep 8. I'd compare it to a task like running a backup. Check the connectivity status from all the nodes and If theCisco Database Replicator (CDR) list is empty for some nodes, refer to Step 8. Connected i. Queue: 0 or varying numbers ii. needs to be opened. Once that command is COMPLETED, outputs can be verified and it shows the current database status. replication issues occur. Step 8. If any errors/mismatches are discovered, theyare shown 03-12-2019 All Rights Reserved. If there is an issue Does it check periodically for changes or only reacts when there is a change made to one of the nodes? "REPL. the Cisco TAC. 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. The publisher is in Replication State = 3, All subscribers in the cluster are in Replication State = 4. Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! Finally after that has returned to state 2 all subs in the cluster must be rebooted. Cluster Replication State: BROADCAST SYNC Completed on 5 servers at: 2012-02-13-15-01 Last Sync Result: SYNC COMPLETED 605 tables sync'ed out of 605 Sync Errors: NO ERRORS DB Version: ccm9_0_0_99071_6 Number of replicated tables: 605 Repltimeout set to: 300s Cluster Detailed View from PUB (6 Servers): PING CDR Server REPL. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Step2: Put the command "utils dbreplication runtimestate". Replication is continuous. Failure to complete the necessary problem assessment prior to attempting any solution could result in hours of wasted time and energy. If any node has a state other than 2, continue to troubleshoot. After you complete Step4, if there are no issues reported, run the. Please refer to the below screenshot. Required fields are marked *. Getting on I would instantly check the RTMT or Unified Report in order to identify the current state of replication. 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. Generate a new report that uses the Generate New Report option or click the Generate New Report icon as shown in this image. LDAP Sync Issues. 2. network connectivity and the securitypassword is same on all the this image. But opting out of some of these cookies may have an effect on your browsing experience. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are 2. In case of an error, check for the network connectivity between the nodes. Full list of CCM servers for replication. thesubscribers syncs the time with the publisher. Generate a new report, and check for a successful connection. In 7.1.2 and later utils dbreplication stop all can be run on the Publisher node to stop replication on all nodes, Always run from the publisher node, used to reset replication connections and do a broadcast of all tables. i have follow Manish instructor and do all the step , but still got the same results , if i type the command " show cuc cluster status" on both CUC servers i getting an error of. Same as above, but may need to be used in cases where above command fails. There are 5 states. This can be run on each node of the cluster by doing utils dbreplication stop. Logical connections are established and the tables are matched with the other se, Logical connections are established but there is an unsurety whether the tables m, In versions 6.x and 7.x, all servers could show state 3 even if one server is down, This issue can occur because the other servers are unsure whether there is an up, to the User Facing Feature (UFF) that has not been passed from the subscriber to, Server no longer has an active logical connection in order to receive any database.
