Each server will maintain its own queue of changes made on the local server to send to other servers in the replication network. 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. The Cisco Unified Reporting CM Database Report (Refer to Step 2). Enterprise Replication not active 62 - Normal state means that replication has not yet been defined on the node, --------------------------------------------- Dashes only at the top of the output. *Note*: Publisher define not listed here. You must check the status for every node. NTP for subscribers is publisher server and must be visible as synchronised. We now do some other checks to prepare to fix replication. DBver& REPL. reachability. If some 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. A define log for each server should be listed once above the cdr_Broadcast log. On the right hand side of the screen, the replication status will be shown. set new default gateway: . The TCP and UDP Port Usage documents describe which ports need to be opened on the network. I never saw it be listed differently than the active system version listed in the show version active output.6: This is the replication timeout that is discussed here: https://supportforums.cisco.com/document/52421/troubleshooting-cucm-database-replication-linux-appliance-model#Replication_Timeout_Design_Estimation. If the Sqlhosts are mismatched along with the host files, follow 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. Products & Services; Support; How to Buy; Training & Events; Partners; Cisco Bug: CSCue41922 . Check the individual components using the utils diagnose If yes, go to Step 8. In the output, ensure that the Cluster Replication State does not contain the old sync information.Check the same using the Timestamp. 'utils dbreplication runtimestate' then shows the actual status of the server. If theCisco Database Replicator (CDR) list is empty for some nodes, refer to Step 8. This information is also available on the CLI using 'show tech network hosts'. are error/mismatched tables,run the command: https://supportforums.cisco.com/document/65041/how-reset-passwords-cucmhttps://supportforums.cisco.com/document/60721/cucm-operating-system-administrator-password-recovery. Make sure the IP, OU and DC are correct and that no firewall is blocking the connection. 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. Sets the "process" value within Informix. 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. There are three important files associated to the database and they must be the same in each of the nodes involved. Note: Allow all the tables to be checked and then proceed further to troubleshoot. Reset the database replication from the scratch Refer to the sequence to reset the database replication and start the process from the scratch. 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). Minutes.Commands to check/set the replication timeout: show tech repltimeout ( To check the current replication timeout After few minutes, use the command "utils dbreplication runtimestate" to check the replication status. Step 8. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes). Ensure that the network connectivity is successful between the New here? 2 Replication isgoodLogical connections are established and the This error is caused when the reverse DNS lookup fails on a node. This is not an exhaustive list. We verify in the report that all of the hosts files look correct. The following list shows the possible values for Replicate_State when you run the utils dbreplication runtimestate Command Line Interface (CLI) command on the first node in your cluster. In other words, a change made on "A" will be sent to "B" by "A". Select Generate a new report. 0 InitializationStateReplication is in the process of setting click the Generate New Reporticon as shown in this image. Love it!!! 2. Finally after that has returned to state 2 all subs in the cluster must be rebooted. 08:29 AM Check the connectivity This can be executed to one node by hostname utils dbreplication reset nodename or on all nodes by utils dbreplication reset all. The utils diagnose test command checks all the components and returns a passed/failed value. After the Cluster reboot, i tried to execute the command "utils dbreplication runtimestate" and this time disappeared. (2) Execute the utils dbreplication stop command on the Publisher. for the CUCM. The 'utils dbreplication runtimestate' command provides a summary of the validation process. I have Question, If the .rhost file is deleted/corrputed, is there a way to recreate it? 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. Restart the following services from the CLI of the publisher Steps to Diagnose the Database Replication, Step 1. Checkes critical dynamic tables for consistency. Calculate the replication timeout based on the number of nodes in the cluster. For further information refer to the link: Troubleshooting CUCM Database Replication Linux Appliance 12:47 PM. Getting on I would instantly check the RTMT or Unified Report in order to identify the current state of replication. A setup failure might have occurred ifreplication is in this With clusters larger than 5 nodes, a 300s repltimeout configuration may not be sufficient. It runs a repair process on all tables in the . If the Sqlhosts are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. These commands allow you to know the status of each of them. If you recieve Cannot send TCP/UDP packets as an error Confirm the connectivity between nodes. Definition: the connection is being established c. Dropped i. Queue: Continuously rising / accumulating ii. this image. a network connectivity problem.Ensure that all the nodes have ping Server "A" must send it to "C" and all other nodes. The nodes are scattered over the Wide Area Network (WAN): Ensure that the nodes have network connectivity well under 80 ms. 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. NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER. whether there is an updateto the User Facing Feature (UFF) that has Also make sure that your user's have the last name field filled in . 0 - Replication Not Started. Note: Changing this parameter improves the replication setup IDS replication is configured so that each server is a "root" node in the replication network. The utils diagnose test command checks all the components and hostnames. Proceed to Step 8, if the status does not change. Wait for it to complete before you start the next step. Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. Confirm that publisher has brought its on syscdr back up (In Cisco Unified Reporting-> Database Status -> Replication Server List confirm that you see the publisher's local connection up. The utils create report database command from CLI. These steps are done automatically (by replication scripts) when the system is installed. 5. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. The Steps 7 and 8 must be performed after the checklist is on the network. Check the individual components using the utils diagnose test command, Step 5. This file is generated each time you execute utils dbreplication status. I'd compare it to a task like running a backup. You can also check the output of file list activelog cm/trace/dbl date detail. Status as shown in this image. Complete these steps in order to check NTP status: Use the utils diagnose test command to check the output, as We now do some other checks to prepare to fix replication. 11-20-2015 This error is caused when one or more nodes in the cluster have a network connectivity problem. Run the utils dbreplication runtimestate command to check the one server is down in the cluster. Do we require these commands ??? "RPC" only instead of DB/RPC/DBMonii. Once an accurate replication status is displayed, check the Try to sync the local servers first. Each subscriber must reach Publisher and other subscribers included in the cluster network connectivity result must be completed successfully. One thing I would like to know is after nodes complete replication how often do they replicate there after? The documentation set for this product strives to use bias-free language. LOOP?" This clears out configuration information from the syscdr database which forces the replicator to reread the configuration files. This issue can occur because the other servers are unsure 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. Step 8. 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. - Ensure that the appropriate TCP/UDP port numbers are allowed 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. the nodes. particular node: utils dbreplication stop (Only on the publisher), utils dbreplcation dropadmindb (Only on the affected Check the same and use the Timestamp. Full list of CCM servers for replication. Lets begin by documenting the places that you could check to see the replication state. 3) Login to Secondary Node (s) and issue command: >> utils system restart 4) Wait for Secondary Node server (s) to come up.
