If the Cisco Database Replicator (CDR) list is empty for some Love it!!! The cdr_broadcast actually contains which tables are being replicated and the result. Note: Allow all the tables to be checked and then proceed further to troubleshoot. ----- Command execution example ----- Customers Also Viewed These Support Documents. The output from CUCM version 10.5.2 NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER The explanation PING REPLICATION REPL. 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. further to troubleshoot. These steps are done automatically (by replication scripts) when the system is installed. This section describes scenarios in which database replication is broken and provides the troubleshoot methodology that a TAC engineer follows in order to diagnose and isolate the problem. Connected i. Queue: 0 or varying numbers ii. Find answers to your questions by entering keywords or phrases in the Search bar above. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Consult the Cisco TAC before proceeding with Step 7 and 8 in In the report the information I find is the following. Required fields are marked *. We now do some other checks to prepare to fix replication. 7: This is the ping time between the servers. NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER. 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. This is an outdated state and is no longer around. Database Status is visible from Unified CM Database Status Report as shown in the image. option from the Navigationdrop-down list in the Cisco Unified It is possible to determine where in the process the replication setup is using commands, log files, and the database status report. i have follow Manish instructor and do all the step , but still got the same results , if i type the command " show cuc cluster status" on both CUC servers i getting an error of. 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. The documentation set for this product strives to use bias-free language. In 7.1.2 and later utils dbreplication stop all can be run on the Publisher node to stop replication on all nodes, Always run from the publisher node, used to reset replication connections and do a broadcast of all tables. flagged as anerror. nodes. Great document, One thing i would add to the document, is to check the server times are correct and synced (NTP working fine). network. Stops currently replication running, restarts A Cisco DB Replicator, deletes marker file used to signal replication to begin. Calculate the replication timeout based on Later examples talk about identifying a corrupt syscdr database. Perform the procedure in the off business hours. Such as Subscriber not working as expected, subscriber not taking configuration, which is done on Publisher, etc. Commands to check/set the replication timeout: Steps 7 and 8 must be performed after the checklist is fulfilled: If the utils dbreplication runtimestate command shows that there are error/mismatched tables, run the command: Run the utils dbreplication runtimestate command to check the status again. If any node has a You can also look in the informix log on that box to confirm this. We verify in the report that all of the hosts files look correct. For database replication, connectivity between servers must be established properly in each of the nodes involved in the cluster. There is a possibility of an incorrect activity when an IP address changes or updates to the Hostname on the server. Steps to Diagnose the Database Replication, Step 1. nodes, refer to Step 8. Proceed to Step 8, if the status does not change. If yes, go to Step 8. Below are these steps. is broken, and provides thetroubleshoot methodology that a TAC 2. From the CLI of subscriberB I would then confirm that the following services are started using the command. If the intra-cluster communication is broken, database Clustering over WAN (CoW) long delays can cause the data sync process to be exponentially longer. If there is an issue Restart these services from the CLI of the publisher server and check if the mismatch is cleared. testcommand. You also have the option to opt-out of these cookies. Can you get the output of show network eth0 detail ? When we do a utils dbreplication reset all they get done again. This can be run on each node of the cluster by doing utils dbreplication stop. Check the connectivity status from all the nodes and The utils dbreplication runtimestate command shows out table across the network. This is likely the best summary of dbreplication I've found yet. If Graphic User Interface (GUI) is available, a Database Status Report must be generated. click the Generate New Reporticon as shown in this image. . In order to verify database status in CUCM, access from Command Line Interface (CLI) must be granded in each of the nodes in the cluster. network. Please refer to the below screenshot. The common error messages as seen in the network connectivity tests: 1. This error is caused when the reverse DNS lookup fails on a Replication REPLICATION SETUP SERVER-NAME IP ADDRESS (msec) DbMon? In case you reach the Cisco TAC for further assistance, ensure The following table lists each command and it's function. If the RTT is unusually high, check network performance. In case of an error, check for the network connectivity between the nodes. 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. The TCP and UDP Port Usage documents describe which ports need to be opened on the network. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. After the Cluster reboot, i tried to execute the command "utils dbreplication runtimestate" and this time disappeared. No replication occurs in this state. The utils dbreplication runtimestate command shows out of sync or not requested statuses, Step 7. 07:42 AM CM Hosts, the Rhosts and theSqlhosts are equivalent on all the states of the Real Time Monitoring Tool (RTMT) for the replication. Verify database replication is broken. Thanks, if I do a manual back up I reserve it for early morning activity. The full list of user facing features is located on the following slide. database status from the Cisco Unified Reporting page on the In a cluster where no nodes have been reinstalled, the publisher would be g_2, the next node installed would be g_3, and so on and so fourth.11: This shows the RTMT states for database replication. 12:47 PM. Select Generate a new report. Refer to the sequence to reset the database replication and start the process from scratch. performance, but consumesadditional system resources. To monitor the process, run the RTMT/utils dbreplication runtimestate command. 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. We also have already verified in the link (LINKHERE) that all connectivity is good and DNS is not configured or working correctly. set new default gateway: . Collect the CM database status from the Cisco Unified The best command to verify DNS is utils diagnose test. 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. Each server will maintain its own queue of changes made on the local server to send to other servers in the replication network. Thank you to each and everyone for the nominations and your support. It is more like a push model than a pull model. - Ensure that the appropriate TCP/UDP port numbers are allowed The show network clustercommand checks for authentication of all nodes. If yes, go toStep 8. Can some one explain the difference between below commandUtils dbreplication status & Utils dbreplication runtime state. , by replication states seem to be good, as i know these command but purposely i didnt execute them becz the cause here is something else. Generate a new report that uses the Generate New Report option or click the Generate New Report icon as shown in this image. This mismatched data is found by issuing a. We also use third-party cookies that help us analyze and understand how you use this website. the proper functioning of the database replication are: The validate_network command checks all aspects of the network 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 cdr list serv is the command that would be used under root access by Cisco TAC to check the current list of replication connections. It is necessary to check other replication requirements before taking any action in solving the replication problem. Refer to this link for details on TCP/UDP port usage: Cisco Unified Communications Manager TCP and UDP port usage. If yes, go to Step 8. nodes, as shown in this image. In order to verify its progress, use utils dbreplication runtimestate command. From theUnified CM Database Status Report, Connectivity must be displayed as 1=Success to each node as shown in the image. Ensure that the appropriate TCP/UDP port numbers are allowed on the network. 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. thesubscribers syncs the time with the publisher. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are Step 8. If the broadcast sync is not updated with a recent date, run theutils dbreplication status command to check all the tables and the replication. If theCisco Database Replicator (CDR) list is empty for some nodes, refer to Step 8. Step 1. 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. Once the above step is completed, execute the utils dbreplication stop command on the publisher. Execute the utils dbreplication stop command on all subscribers. It is extremely important for the NTP to be fully functional in order to avoid any database replication issues. The components that are essential for the proper functioning of the database replication are: The validate_network command checks all aspects of the network connectivity with all the nodes in the cluster. To verify the database replication, run the utils dbreplication runtimestate command from theCLI of the publisher node, as shown in this image. 4 SetupFailed/DroppedServer no longer has an active logical Cisco TAC. Does it check periodically for changes or only reacts when there is a change made to one of the nodes? The documentation on checking connectivity is linked below. Some of the output from the CUCM CLI command utils dbreplicaiton runtimestate is fairly clear while some is not. In versions 6.x and 7.x, all servers could show state 3 even if Find answers to your questions by entering keywords or phrases in the Search bar above. Certain commands are not available in each version of CUCM. 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. This issue can occur because the other servers are unsure This state is rarely seen in the Sqlhosts files are mismatched, run the command from, http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/10_0_1/ipchange/CUCM_BK_C3782AAB_00_change-ipaddress-hostname-100/CUCM_BK_C3782AAB_00_change-ipaddress-hostname-100_chapter_011.html, Generate a new report and check if the Sqlhost files are Normally run on a subscriber. according the command " file view activelog cm/log/informix/ccm.log . If no, contact Cisco TAC. For further information refer to the link: Troubleshooting CUCM Database Replication Linux Appliance Database replication commands must be run from the publisher. Do we require these commands ??? Thanks for the quick response. No replication occurs in this state. 4. Restart the following services from the CLI of the publisher 09-14-2017 Generate a new report, and check for a successful connection. On the Publisher, enter the utils dbreplication dropadmindb command. If this fails, contact the Saved me hours of extra work. Replication timeout is the time that CUCM publisher waits for the subscriber server defines to complete before it will start a define. A setup failure can occur if replication is in this state for more than an hour. 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. 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. https://supportforums.cisco.com/t5/collaboration-voice-and-video/rtmt/ba-p/3102764. If you recieve Cannot send TCP/UDP packets as an error On the Publisher and Subscriber, enter the utils dbreplication runtimestate command. 10:20 AM. At the publisher server, issue the utils dbreplication reset all. New here? Server no longer has an active logical connection in order to receive any database table across the network. the number of nodesin the cluster. If no, contact Cisco TAC. If some Thepublisher always syncs the time with You can also check the output of file list activelog cm/trace/dbl date detail. commandcompletes the operation in 300 seconds. We verify in the report that all of the hosts files look correct. Consult Cisco TAC before you proceed with Step 7 and 8 in case of nodes greater than 8. Same as above, but may need to be used in cases where above command fails. This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. " is " YES ". nodes. Note: Changing this parameter improves the replication setup the Cisco TAC. The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. UC Collabing 2023. this image. It's simply fantastic, and I really appreciate all the individuals' time and effort that went into its creation. I'll run in before the rooster wakes. network utils.

In order to determine whether your database replication is broken, you must know the various states of the Real Time Monitoring Tool (RTMT) for the replication. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. Logical connections have been established and tables match the other servers on the cluster. Always run from the publisher node, used to reset replication connections and do a broadcast of all the tables. Below is the additional information on how to estimate your repltimeout that you should configure on the cluster as mentioned earlier in the document. DBver& REPL. address/Hostname. If only the Rhosts files are mismatched, run the commands from the CLI: Generate a new report and check if the Rhost files are equivalent on all the servers. nodes are not able to join the replicationprocess, increase the Repair all/selective the tables for database replication, This document describes how to diagnose database replication issues and provides the steps. This is an important step. Note: This command is no longer functional as of CUCM 9.0(1). issues and provides the stepsnecessary to troubleshoot and resolve The files we are referring to here are listed below. returns a passed/failed value.The components that are essential for Check the individual components that use the utils diagnose test command, Step 5. If no, contact Cisco TAC. Based on the version of CUCM in use you may see the following: i. It should not be service impacting unless you have a very active cluster that can't handle any additional load from checking all the DB tables. Replication is in the process of setting up. CUCM Database Replication is an area in which Cisco customers and partners have asked for more in-depth training in being able to properly assess a replication problem and potentially resolve an issue without involving TAC. But, "B" will not send that same change on to "C". Thus the recommendation to the customer would be to follow the most basic process that fixes about 50 percent of replication cases. 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. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes).
