----- Command execution example ----- broken, you must know the variousstates of the Real Time Monitoring The show network clustercommand checks for authentication of all nodes. The broadcast is shown in yellow. The following table lists each command and it's function. This file is used to locally resolve hostnames to IP addresses. If your network is live, ensure that you understand the potential impact of any command. Certain commands are not available in each version of CUCM. http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/port/9_1_1/CUCM_BK_T2CA6EDE_00_tcp-port-usage-guide-91/CUCM_BK_T2CA6EDE_00_tcp-port-usage-guide-91_chapter_01.html. Example: 12 Servers in CUCMStep 3. Review the Unified CM Database Report any component utils dbreplication stop all (Only on the publisher), utils dbreplication dropadmindb (First on all the subscribers 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. This error is caused when the reverse DNS lookup fails on a node. This section describes scenarios in which database replication There is a possibility of an incorrect activity when an IP address changes or updates to the Hostname on the server. When we do a utils dbreplication reset all they get done again. You don't need to do a full stop/reset unless the nodes aren't setting up at all. The Steps 7 and 8 must be performed after the checklist is This error is caused when one or more nodes in the cluster have In case of an error, check for the network connectivity between the nodes. The full list of user facing features is located on the following slide. Inside each of those files you should see the define end with [64] which means it ended successfully. 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. thesubscribers syncs the time with the publisher. Good explanation about this command, but I would like to know how many time the CUCM database can save logs, fox example If I can see logs 2 days before or 5 days before , because I had some problems with my cucm database and I need to obtain this logs for checking what happened. In the report the information I find is the following. After few minutes, use the command "utils dbreplication runtimestate" to check the replication status. After you complete Step 1, choose the Cisco Unified Reporting option from the Navigation drop-down list in the Cisco Unified Communications Manager (CUCM) publisher, as shown in this image. whether there is an updateto the User Facing Feature (UFF) that has Recommended to set to 40 for large clusters (10+ nodes). connectivity with all the nodesin the cluster. Love it!!! In other words, a change made on "A" will be sent to "B" by "A". https://supportforums.cisco.com/t5/collaboration-voice-and-video/rtmt/ba-p/3102764. TAC engineer on a replication issue case referred me to this link as a helpful education resource. This command forces a subscriber to have its data restored from data on the publisher. Repair all/selective tables for database replication, Step 8. Thanks, if I do a manual back up I reserve it for early morning activity. Cluster : Server 1-5 * 1 min = 5 min, + 6-10 * 2 min = 10 min, From theUnified CM Database Status Report, Connectivity must be displayed as 1=Success to each node as shown in the image. After you complete Step 1, select the Cisco Unified Reporting Repair all/selective the tables for If we have a define for every server following a reset then things are more than likely looking good. 5. - Ensure that the appropriate TCP/UDP port numbers are allowed After all subscribers have been defined we then wait the repltimeout (Can check from show tech repltimeout) it will then do a broadcast file that actually pushes the replicates across. 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. The best command to verify DNS is utils diagnose test. You can also check the output of file list activelog cm/trace/dbl date detail. returns a passed/failed value.The components that are essential for No replication occurs in this state. of the node using the utils service list command. 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. 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). Database replication can be damaged due to ungraceful shutdowns and they are visible in System-history log. If the intra-cluster communication is broken, database replication issues occur. Find answers to your questions by entering keywords or phrases in the Search bar above. Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). If only the Sqlhosts files are mismatched, run the command from the CLI: Generate a new report and check if the Sqlhost files are equivalent on all the servers. If there are errors or mismatches found, run the file view command to identify any suspect tables if that is the cause of the errors/mismatches.5: This is the database version. If still it does not resolved, would recommend you to involve TAC . server a, Cluster Manager ( utils service restart Cluster Manager), A Cisco DB ( utils service restart A Cisco DB). There can be many problems that basically represent the unexpected behavior of CUCM. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I'd compare it to a task like running a backup. case of nodes greater than 8. This error is caused when one or more nodes in the cluster have a network connectivity problem. These cookies will be stored in your browser only with your consent. 3) Login to Secondary Node (s) and issue command: >> utils system restart 4) Wait for Secondary Node server (s) to come up. If yes, go to Step 8. follow the steps mentioned under TheHosts files are mismatched. Connecting i. Queue: Blank ii. All rights reserved. Servers here should have the correct hostname and node id (populated from the process node table). Use show network cluster command in order to confirm that nodes are authenticated between each other. Set up is still in progress. If any node has a state other than 2, continue to troubleshoot. that the following outputs and thereports are provided: The Cisco Unified Reporting CM Database Report (Refer to Step To check all tables run. (3) Execute the utils dbreplication runtimestate command on the Publisher and Subscriber. Cluster Detailed View from PUB01DC (3 Servers): PING CDR Server REPL.

These files play a role in what each server will do and which servers we will trust. This is an important step. database status from the Cisco Unified Reporting page on the We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. The validate_network command completes the operation in 300 seconds. the Cisco TAC. 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). 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). DBver& REPL. issues and provides the stepsnecessary to troubleshoot and resolve My go-to when troubleshooting database replication. Step 8. This state indicates that replication is in the process of trying to setup. 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. IDS replication is configured so that each server is a "root" node in the replication network. As shown in this image, the Unified cluster: The replication timeout(Default: 300 Seconds) is the time If the A Cisco DB service is down, run the utils service start A Step 2. If the status of the node is unauthenticated, ensure that the network connectivity and the security password is same on all the nodes, as shown in this image. Error, Intra-cluster communication is broken, as shown in this image. Great guide! Thanks for taking the time to put it together. a network connectivity problem.Ensure that all the nodes have ping After checking the current stat of replication using one of the previous methods, we can use the table below to understand what each state means. In case of an unsuccessful connection, go to Step 8. Verify database replication is brokenStep 2. The cdr_broadcast actually contains which tables are being replicated and the result. high, check network performance. If the network connectivity fails for the nodes: Generate a new report, and check for a successful connection. There is a possibility of an incorrect activity when an IP 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 ). 2. g_# with the number being the node id. Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. reachable with a lower RoundTrip Time (RTT). Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery, Step 6. This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. Ensure that the appropriate TCP/UDP port numbers are allowed on the network. 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. Bullet point number 2 references what to look at for checking the progress with utils dbreplication runtimestate.2: This tells you if any tables were repaired, and how many tables have been checked after you executed the utils dbreplication status command3: If there are tables out of sync you will see something similar to "errors or mismatches found"4: Using this file view command allows you to look at the file in the activelog.
