Very detailed. Restart the following services from the CLI of the publisher utils dbreplication stop on all subscribers. This clears out configuration information from the syscdr database which forces the replicator to reread the configuration files. I'll run in before the rooster wakes. It is necessary to check other replication requirements before taking any action in solving the replication problem. this image. Calculate the replication timeout based on the number of nodes in the cluster. (, All nodes in the cluster are in Replication State = 3. This error is caused when one or more nodes in the cluster have 2. In the output, ensure that the Cluster Replication State does Once it is generated, download and save the report so that it 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. Ensure that the port number 1515 is allowed on the network. cluster. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes).

Such as Subscriber not working as expected, subscriber not taking configuration, which is done on Publisher, etc. Network Time Protocol (NTP) Reachability: The NTP is responsible for keeping the server's time in sync Runtimestate command shows the progress of the database status so it can display different Replication Setup for the nodes while it is in progress. Repair all/selective the tables for There are three important files associated to the database and they must be the same in each of the nodes involved. TCP/UDP ports. Check the connectivity Inside each of those files you should see the define end with [64] which means it ended successfully. a network connectivity problem.Ensure that all the nodes have ping In 6.x and 7.x all servers could show state 3 if one server is down in the cluster. Calculate the replication timeout based on utils network ping utils network traceroute utils network arp list. tables are matched with the other serverson the cluster. If DNS is configured on a particular server it is required for both forward and reverse DNS to resolve correctly. The utils create report database command from CLI. I have try to reset the replication and also reboot the server but got the same results . 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 STATUS": This lets you know if the node is connected or offlineiii. After you complete Step 4, if there are no issues reported, run The logical connections discussed above are the connections seen in the Topology Diagram in the begining of this document. Navigate to System Reports and click Unified CM Database Status as shown in this image. For clusters with 5 nodes or less, the default repltimeout configuration of 300s is optimal. UC Collabing 2023. Remove database replication (utils uccx dbreplication teardown) Setup database replication (utils uccx dbreplication setup) Initiate a data repair process for all the databases (utils uccx dbreplication repair all). Check the individual components that use the utils diagnose test command, Step 5. case of an unsuccessfulconnection, go to Step 8. status again. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. No replication is occurring in this state. Cluster Detailed View from ccm125p (2 Servers): PING DB/RPC/ REPL. That would be covered under the "utils diagnose test" section. 07:42 AM still in progress. The publisher establishes a connection to every server in the cluster and the subscribers establish a connection the local database and the publisher only. All the nodes have the connectivity to each other. Execute the utils dbreplication stop command on all subscribers. 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. the Cisco TAC. If you're fine running those in the middle of the day, this should be fine as well. If this is above 80 ms then the network is not in compliance the SRND.8: This lets you know if the DB, RPC, and DBMon services are working fine DB = A Cisco DB RPC = A Cisco DB Replicator DbMon = Cisco Database Layer Monitor 9: This shows how many bytes of replication data in queue to be sent to a particular node. Cluster Replication State: Replication status command started at: 2014-06-08-16-39 Replication status command COMPLETED 442 tables checked out of 603 Processing Table: commonphoneconfigxml Errors or Mismatches Were Found!!! Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery, Step 6. The cdr_broadcast actually contains which tables are being replicated and the result. 2. Example: 12 Servers in You don't need to do a full stop/reset unless the nodes aren't setting up at all. Below are these steps. Collect the CM No replication occurs in this state. On the Publisher, enter the utils dbreplication dropadmindb command. This is likely the best summary of dbreplication I've found yet. order to avoid any databasereplication issues. nodes in the cluster. We verify in the report that all of the hosts files look correct. Definition: the connection is being established c. Dropped i. Queue: Continuously rising / accumulating ii. This mismatched data is found by issuing a. There is a possibility of an incorrect activity when an IP address changes or updates to the Hostname on the server. 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. These commands allow you to know the status of each of them. Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! reachability. Check the connectivity status from all the nodes and As shown in this image, the Unified CM Hosts, the Rhosts and the Sqlhosts are equivalent on all the nodes. If you recieve Cannot send TCP/UDP packets as an error cluster: The replication timeout(Default: 300 Seconds) is the time option from the Navigationdrop-down list in the Cisco Unified However, Unified CM Database Status Report also displays this information as shown in the image. Database replication commands must be run from the publisher. 5.x, it indicates that the setup is still in progress. only the Rhosts files are mismatched, run the commands from If no, contact Cisco TAC. 06-08-2014 DBver& REPL. If yes, go toStep 8. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. 03-16-2019 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. This enables multithreading and improves replication setup time at the slight cost of processing power. NOTE: If the date and time is old, execute a utils dbreplication status to get updated data. This website uses cookies to improve your experience. (*) The command execution example is the same as in (1). Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). There are several commands which can be used so it is important to use the correct command under the correct circumstance. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. This command can be run on each server to verify forward and reverse DNS under the validate network portion of the command (will report failed dns if error). Repair all/selective the tables for database 4. Each subscriber must reach Publisher and other subscribers included in the cluster network connectivity result must be completed successfully. Database replication can be damaged due to ungraceful shutdowns and they are visible in System-history log. Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! Server 1-5 = 1 Minute Per ServerServers 6-10 = 2 Minutes Per hello is successful, asshown in this image. 10:20 AM. We now do some other checks to prepare to fix replication. Once completed, follow Step 3. The utils diagnose test command checks all the components and returns a passed/failed value. Confirm the connectivity between nodes. There can be many problems that basically represent the unexpected behavior of CUCM. one server is down in the cluster. As shown in this image, the Unified But opting out of some of these cookies may have an effect on your browsing experience. Refer to Step 5. the nodes. However, you can verifywhether the DNS is configured and If the Rhosts files are mismatched along with the host files, Timestamp. If the RPC hello does not work for a particular node: - Ensure the network connectivity between the particular node nodes. Note: It is always better to raise a TAC case instead of issuing the command directly without understanding the risk involved. Check the individual components using the utils diagnose Cisco highly recommends to configure a Network Time Protocol (NTP) server with Stratum-1, Stratum-2, or Stratum-3 in CUCM publisher, in order to ensure that the cluster time is synchronized with an external time source. network. If no, contact (2) Execute the utils dbreplication stop command on the Publisher. If there are any errors in the components, the errors will be It's simply fantastic, and I really appreciate all the individuals' time and effort that went into its creation. 4 SetupFailed/DroppedServer no longer has an active logical 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. We now do some other checks to prepare to fix replication. runtimestate command. Wait for it to complete before you start the next step. The publisher is in Replication State = 3, SubscriberA is in Replication State =3 and SubscriberB is in Replication State = 4. Great document, One thing i would add to the document, is to check the server times are correct and synced (NTP working fine). 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. value ), utils dbreplication setrepltimeout ( To set the replication NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER. Same as above, but may need to be used in cases where above command fails. admin:utils dbreplication runtimestate. When we do a utils dbreplication reset all they get done again. 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. An excellent and comprehensive DB replication guide! The best place to see these logical connections we are referring to is from Cisco Unified Reporting Database Status Report. 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 Graphic User Interface (GUI) is available, a Database Status Report must be generated. It runs a repair process on all tables in the . You must check the status for every node. Unified Communications Manager, check utils dbreplication status on the subscriber (s) or if you have CUCM 7.1.5 check utils dbreplication runtimestate. Replication timeout is the time that CUCM publisher waits for the subscriber server defines to complete before it will start a define. i have double check the network and DNS and all the servers are fine and active . state for more than an hour. 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. parent reference clock) must be less. Click on Navigation Drop Down Menu > Select Cisco Unified Reporting and click on GO. No replication occurs in this state. Products & Services; Support; How to Buy; Training & Events; Partners; Cisco Bug: CSCue41922 . not requested statusesStep 7. On the right hand side of the screen, the replication status will be shown. Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. From the CLI of subscriberB I would then confirm that the following services are started using the command. The utils dbreplication runtimestate command shows out In 5.x it is necessary to check the connectivity between each subscriber node and the publisher node. image. Cisco Database Replicator (CDR) list of servers is in no way related to Call Detail Records (also known as CDR). Based on the version of CUCM in use you may see the following: i. Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery. If only their defined messages. Replication REPLICATION SETUP SERVER-NAME IP ADDRESS (msec) DbMon? Connected i. Queue: 0 or varying numbers ii. Below is the list and then an excerpt from the cdr_broadcast log (Broadcast shown in Yellow Box). high, check network performance. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. up. Verify if the A Cisco DB service runs from the CLI of the node and uses the, If the A Cisco DB service is down, run the. with the reference clock. 3. 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. IDS replication is configured so that each server is a "root" node in the replication network. They both follow a hub and spoke topology. Communications Manager 5.x has a similar replication topology to Callmanager 4.X. It depends on the environment. Ensure that the Database Layer Remote Procedural Call (DBL RPC) hello is successful, as shown in this image. Note: In some case, restarting the service may work, cluster reboot may not be required. connectivity with all the nodesin the cluster. nd check if the mismatch is cleared. Model, Step 2. the proper functioning of the database replication are: The validate_network command checks all aspects of the network Thepublisher always syncs the time with 1: This lets you know the last action performed and the time of the action. 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.
