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. 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. this image. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. 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. Cluster : Server 1-5 * 1 min = 5 min, + 6-10 * 2 min = 10 min, A setup failure might have occurred ifreplication is in this It is important to verify the state of replication that is being provided by any of these 3 methods. This clears out configuration information from the syscdr database which forces the replicator to reread the configuration files. Clustering over WAN (CoW) long delays can cause the data sync process to be exponentially longer. "REPL.

This command can be run on all subscribers at the same time but needs to complete on all subscribers prior to being run on the publisher. In order to determine whether your database replication is This should show corresponding defines for each subscriber in the cluster. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. " is " YES ". My go-to when troubleshooting database replication. If yes, go toStep 8. 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. Step 2. Ensure the Local and the Publisher databases are accessible. This change in topology overcomes previous limitations in replication architecture, as changes can now be made to local subscriber databases for user facing faetures even while the publisher is inaccessible. Ensure that: The nodes are in the same Data Center/Site: All the nodes are Symptom: 'utils dbreplication status' is run to take a snapshot of the replication status of a Cisco Unified Operating System (CUOS) server. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are equivalent on all the nodes. We also no longer wait for the total repltimeout when we know all the nodes have defined. database status from the Cisco Unified Reporting page on the 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 We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Step 3. Review the Unified CM Database Report any component status from all the nodes and ensure they are authenticatedStep 6. In order to verify them from CLI, root access is required. on the network. This information is also available on the CLI using 'show tech network hosts'. with connectivity, an error is often displayed on the DomainName Upon completion, proceed to the next step. connectivity with all the nodesin the cluster. A. replication is in this state for more than an hour. The publisher establishes a connection to every server in the cluster and the subscribers establish a connection the local database and the publisher only. nodes, as shown in this image: If the network connectivty fails for the nodes: - Ensure that the network reachability is present between the issues and provides the stepsnecessary to troubleshoot and resolve Ensure the network connectivity between the particular node and the publisher. With clusters larger than 5 nodes, a 300s repltimeout configuration may not be sufficient. Note: Allow all the tables to be checked and then proceed The 'utils dbreplication runtimestate' command provides a summary of the validation process. Execute the utils dbreplication stop command on all subscribers. If the Rhosts files are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. 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. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. Thanks for taking the time to put it together.

(ID) & STATUS QUEUE TABLES LOOP? value ), utils dbreplication setrepltimeout ( To set the replication Step1: Open CUCM CLI via Putty. 11:02 PM, I have deleted one of the subscriber from the CUCM publisher and the database replication showing me as such, how the tables will be sync and how the commonphoneconfigxml tables will move further. 09-14-2017 This file is generated each time you execute utils dbreplication status. this image. In the event the publisher goes down or becomes inaccessible the subscribers will use their local copy of the database. In versions 6.x and 7.x, all servers could show state 3 even if one server is down in the cluster. It runs a repair process on all tables in the . Navigate to System Reports and click Unified CM Database Status as shown in this image. Use this command only after the 'utils dbreplication repair' command has been run several times and the 'utils dbreplication status' ouput still shows non-dynamic tables out of sync. The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. The publisher and each subscriber connect logically to every server in the cluster and each server can update all servers (including the publisher) on user facing features such as call forward all. The documentation set for this product strives to use bias-free language. connection in order to receive any databasetable across the However, Unified CM Database Status Report also displays this information as shown in the image. Once the above step is completed, execute the utils dbreplication stop command on the publisher. Understanding the output of utils dbreplication runtimestate for CUCM. Cisco TAC.

Select Generate a new report. 2. whether there is an updateto the User Facing Feature (UFF) that has still in progress. that the publisher waits for all the subscribers in order tosend of sync ornot requested statuses. 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. Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. We now do some other checks to prepare to fix replication. You could probably pull the following and see if you find anything. This command only triggers the check of the dabatase status. Note: This command is no longer functional as of CUCM 9.0(1). Execute the utils dbreplication stop command on all subscribers. PING REPLICATION REPL. 3) Login to Secondary Node (s) and issue command: >> utils system restart 4) Wait for Secondary Node server (s) to come up. Check Database Replication using Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM) Login to Cisco Unified Communication Manager If the intra-cluster communication is broken, database Run on a publisher or subscriber, this command is used to drop the syscdr database. Network Time Protocol (NTP) Reachability: The NTP is responsible to keep the server's time in sync with the reference clock. needs to be opened. In 6.x and 7.x all servers could show state 3 if one server is down in the cluster. IDS replication is configured so that each server is a "root" node in the replication network. Communications Manager 5.x has a similar replication topology to Callmanager 4.X. Complete these steps in order to check NTP status: Use the utils diagnose test command to check the output, as 1) Login to Primary Node and issue command: >> utils system restart 2) Wait for the server to come up, if you can open Web interface, service is fully functional. If you recieve Cannot send TCP/UDP packets as an error equivalent on all the servers. 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). set new default gateway: . Once that command is COMPLETED, outputs can be verified and it shows the current database status. If any node has a state other than 2, continue to troubleshoot. If this fails, contact the It is essential that the NTP stratum (Number of hops to the Below is a list of some user facing features that can be updated by the subscriber and therefore updated while the publisher is down. Refer to this link in order to change IP address to the Hostname authentication of all nodes. This error is caused when the reverse DNS lookup fails on a node. 5.
