Review the Unified CM Database Report any component We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. Thanks a lot for this easy-to-understand and highly useful guide!! Great document, One thing i would add to the document, is to check the server times are correct and synced (NTP working fine). Error checking is ignored. message, check your network forany retransmissions or block the those issues. 0 InitializationStateReplication is in the process of setting On the Publisher and Subscriber, enter the utils dbreplication runtimestate command. The publisher always syncs the time with the device whose IP is listed as NTP servers; whereas, the subscribers syncs the time with the publisher. Ensure that the network connectivity is successful between the stateother than 2, continue to troubleshoot. 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). 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 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). There is a possibility of an incorrect activity when an IP 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. one server is down in the cluster. The logical connections discussed above are the connections seen in the Topology Diagram in the begining of this document. Thanks for taking the time to put it together. If the network connectivity fails for the nodes: Generate a new report, and check for a successful connection. the utils diagnose test commandStep 5. Customers Also Viewed These Support Documents. 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. fulfilled: All the nodes have the connectivity to each other. Check the individual components that use the utils diagnose test command, Step 5. I have check the system and all networking is fine , the server are fine . 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. equivalent on all the servers. Being in this state for a period longer than an hour could indicate a failure in setup. address changes or updates to theHostname on the server. replication issues occur. The utils diagnose test command checks all the components and These commands allow you to know the status of each of them. The validate_network command completes the operation in 300 seconds. follow the steps mentioned under TheHosts files are mismatched. 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 ). Once that command is COMPLETED, outputs can be verified and it shows the current database status. Verify database replication is broken. Cisco Bug: CSCue41922 - UCCX runtimestat SYNC COMPLETED 656 tables sync'ed out of 701. Cluster Manager populates this file and is used for local name resolution. If yes, go to Step 8. It is extremely important for the NTP to be fully functional in order to avoid any database replication issues. 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. If your network is live, ensure that you understand the potential impact of any command. 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. In the report the information I find is the following. utils dbreplication repair -- in CUCM 5.x, this command meant a reset of the replication, whereas, in CUCM 6.10 and higher versions, this means a repair of the data. This is likely the best summary of dbreplication I've found yet. 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. LOOP?" Thepublisher always syncs the time with If the RPC hello does not work for a particular node: - Ensure the network connectivity between the particular node In other words, a change made on "A" will be sent to "B" by "A". We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. This could indicate a corrupt syscdr. Replication is continuous. Later examples talk about identifying a corrupt syscdr database. Ensure that all the nodes have ping reachability. Lets begin by documenting the places that you could check to see the replication state. It depends on the environment. If the A Cisco DB service is down, run the utils service start A a network connectivity problem.Ensure that all the nodes have ping Login to Cisco Unified Communication Manager > Navigate to Application > Plugins > Click Find, Click on Download > Cisco Unified CM Real-Time Monitoring Tool Windows, Once the tool is downloaded > Install the Tool as you install other software applications, Once the installation is completed > Launch Real Time Monitoring Tool Application on your machine, Host IP Address > Enter the IP Address of Cisco Unified Communication Manager >, Username > Enter the Username of Cisco Unified Communication Manager, Password > Enter the Password of Cisco Unified Communication Manager. Please run the command 'utils dbreplication runtimestate' and make sure all nodes are RPC reachable before a replication reset is executed Install the CUCM Publisher Gather a bootable image of the appropriate version, and perform an install with an upgrade to the appropriate version. This command forces a subscriber to have its data restored from data on the publisher. this image. for the CUCM. My go-to when troubleshooting database replication. the nodes. After you run the command, all the tables are checked for Ensure that the port number 1515 is allowed on the network. Thanks, if I do a manual back up I reserve it for early morning activity. This error is caused when one or more nodes in the cluster have At this point this is when I would first take a step back and make sure all the services are running correctly on our SubscriberB. If the utils dbreplication runtimestate command shows that there Tool (RTMT) for the replication. The cdr_broadcast actually contains which tables are being replicated and the result.

Processnode table must list all nodes in the cluster. 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. As illustrated in the figure below, only the publisher's database is writable while each subscriber contains a read only database. Collect the CM database status from the Cisco Unified Ensure that: The nodes are in the same Data Center/Site: All the nodes are reachable with a lower Round Trip Time (RTT). Use 'file view activelog cm/trace/dbl/sdi/ReplicationStatus.2014_06_08_16_39_01.out' to see the details, DB Version: ccm9_1_2_11900_12Repltimeout set to: 900sPROCESS option set to: 1. - Ensure that the appropriate TCP/UDP port numbers are allowed This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. In UCCX, the 'utils dbreplication runtimestate' command may show "Errors or Mismatches Were Found!! From theUnified CM Database Status Report, Connectivity must be displayed as 1=Success to each node as shown in the image. 09-14-2017 The files we are referring to here are listed below. Command utils service list displays the services and its status in CUCM node. equivalent on all the nodes. Reset the database replication from the In order to verify them from CLI, root access is required. Replication is in the process of setting up. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. Confirm the connectivity between nodes. particular node: utils dbreplication stop (Only on the publisher), utils dbreplcation dropadmindb (Only on the affected ensure they areauthenticated. 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. 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. cluster. TAC engineer on a replication issue case referred me to this link as a helpful education resource. All the nodes have the connectivity to each other. 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. 1: This lets you know the last action performed and the time of the action. If no, contact Cisco TAC. Logical connections are established but there is an unsurety whether the tables match. show tech network routes. Step 1. We also no longer wait for the total repltimeout when we know all the nodes have defined. It checks all the components and returns passed/failed value. If this fails, contact the 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. flagged with a red cross icon, asshown in this image. case of nodes greater than 8.

However, Unified CM Database Status Report also displays this information as shown in the image. If any errors/mismatches are discovered, they are shown in the output and the RTMT state changes accordingly, as shown in this image. Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). Step 8. whether the tables match. Proceed to Step 8, if the status does not change. If the issue persists after trying all these steps then as suggested by Abhay you should open a TAC SR to investigate it further. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. not requested statusesStep 7. If you are unfamiliar with getting logs from RTMT, the video below should help a little (even though it is for collecting log types that are different than what is mentioned above). New here? Complete these steps in order to check NTP status: Use the utils diagnose test command to check the output, as 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. Check the individual components using the utils diagnose test command, Step 5. Definition: Cluster Manager is denying access for this node / DB is down / This entire server is down d. Disconnect i.
