Cluster : Server 1-5 * 1 min = 5 min, + 6-10 * 2 min = 10 min, Restart these services from the CLI of the publisher server and check if the mismatch is cleared. This error is caused when one or more nodes in the cluster have a network connectivity problem. runtimestate command. Upon completion, proceed to the next step. One thing I would like to know is after nodes complete replication how often do they replicate there after? You can follow all the T-shooting links provided by Manish and I. 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. The output from the publisher contains processnode table entries. Definition: the connection is being established c. Dropped i. Queue: Continuously rising / accumulating ii. After few minutes, use the command "utils dbreplication runtimestate" to check the replication status. 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. Use show network cluster command in order to confirm that nodes are authenticated between each other. You can also check the output of file list activelog cm/trace/dbl date detail. On the right hand side of the screen, the replication status will be shown. messages as seen in the networkconnectivity tests: 1. Thanks for taking the time to put it together.

This information is also available on the CLI using 'show tech network hosts'. Ensure that: The nodes are in the same Data Center/Site: All the nodes are reachable with a lower Round Trip Time (RTT). Ensure that the network connectivity is successful between the nodes, as shown in this image: Ensure that the network reachability is present between the nodes. There are 5 states. parameter to a higher value as shown. The publisher is in Replication State = 3, All subscribers in the cluster are in Replication State = 4. Step 4. 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. In RTMT, Choose CallManager->Service->Database Summary. 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. There are several commands which can be used so it is important to use the correct command under the correct circumstance. If no, contact Cisco TAC. flagged as anerror. Steps to Diagnose the Database Replication, Step 1. 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. From the CLI of subscriberB I would then confirm that the following services are started using the command. Refer to this link in order to change IP address to the Hostname 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). Verify database replication is brokenStep 2. states of the Real Time Monitoring Tool (RTMT) for the replication. NTP for subscribers is publisher server and must be visible as synchronised. 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. - edited g_# with the number being the node id. 7: This is the ping time between the servers. ----- Command execution example ----- Error, Intra-cluster communication is broken, as shown in We'll assume you're ok with this, but you can opt-out if you wish. - edited case of nodes greater than 8. nodes, as shown in this image. A setup failure can occur if replication is in this state for more than an hour. start the process from the scratch. Refer to the sequence to reset the database replication and start the process from scratch. Ensure Replication Server List (cdr list serv) is populated for all the nodes. Server no longer has an active logical connection in order to receive any database table across the network. In order to determine whether your database replication is 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. The utils diagnose test command checks all the components and on the network. Also make sure that your user's have the last name field filled in . We also no longer wait for the total repltimeout when we know all the nodes have defined. Step 8. If yes, go to Step 8. shown in this image.1. nodes, as shown in this image: If the network connectivty fails for the nodes: - Ensure that the network reachability is present between the To check all tables run.

REPLICATION SETUPSERVER-NAME IP ADDRESS (msec) RPC? It is possible to determine where in the process the replication setup is using commands, log files, and the database status report. 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. Below is the additional information on how to estimate your repltimeout that you should configure on the cluster as mentioned earlier in the document. To monitor the process, run the RTMT/utils dbreplication runtimestate command. However, Unified CM Database Status Report also displays this information as shown in the image. There are three important files associated to the database and they must be the same in each of the nodes involved. - Ensure that the appropriate TCP/UDP port numbers are allowed nodes. +11-12 * 3 min = 6 min, Repltimeout should be set to 21 Once that command is COMPLETED, outputs can be verified and it shows the current database status. Server 1-5 = 1 Minute Per ServerServers 6-10 = 2 Minutes Per Generate a new report that uses the Generate New Report option or click the Generate New Report icon as shown in this image. Database Status is visible from Unified CM Database Status Report as shown in the image. Following this command 'utils dbreplication reset all' should be run in order to get correct status information. These services must be displayed as STARTED. You also have the option to opt-out of these cookies. Customers Also Viewed These Support Documents. No replication occurs in this state. this image. Error, Intra-cluster communication is broken, as shown in this image. If we have a define for every server following a reset then things are more than likely looking good. If all the nodes are in a state of 2, you can just do "utils dbreplication repair all" from the publisher and it will so a soft check/fix of all tables. Saved me hours of extra work. Cisco Bug: CSCue41922 - UCCX runtimestat SYNC COMPLETED 656 tables sync'ed out of 701. After you complete Step 4, if there are no issues reported, run Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are equivalent on all the nodes. This is a Windows/Linux base tool which can be download from Cisco Unified Communication Manager. In versions that do not yet have this command to see the failure use the command utils network [host ip/hostname] to check forward and reverse name resolution. TCP/UDP ports. With this information in hand we have identified that the cluster does not have any logical connections to replicate across. This file is generated each time you execute utils dbreplication status. Check the individual components using the utils diagnose The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. hostnames. cluster: The replication timeout(Default: 300 Seconds) is the time that the nodes havenetwork connecitivty well under 80 ms. 4.

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. A. replication is in this state for more than an hour. 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. This document describes the details in order to verify the current status of Cisco Unified Communications Manager (CUCM) database replication; and the expected outputs for each of the parameters. Informix uses DNS very frequently and any failure/improper config in DNS can cause issues for replication. Note: Allow all the tables to be checked and then proceed Calculate the replication timeout based on the number of nodes in the cluster. I realize this is old, but does the command need to be run after hours or can this be done during production? case of an unsuccessfulconnection, go to Step 8. To monitor the process, run the RTMT/utils dbreplication Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery. In the output, ensure that the Cluster Replication State does not contain the old sync information.

Note: This command is no longer functional as of CUCM 9.0(1). 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. Replication REPLICATION SETUP SERVER-NAME IP ADDRESS (msec) DbMon? In versions 6.x and 7.x, all servers could show state 3 even if one server is down in the cluster. Thank you to each and everyone for the nominations and your support. Check the connectivity status from all the nodes and high, check network performance. Verify if the A CiscoDB service is running from the CLI UC Collabing 2023. This document describes how to diagnose database replication in the output and the RTMT state changes accordingly, as shown in We also use third-party cookies that help us analyze and understand how you use this website. We now do some other checks to prepare to fix replication. Sets the "process" value within Informix. Great articleappreciate your hard work on this stuff ! Use this command only after the 'utils dbreplication repair' command has been run several times and the 'utils dbreplication status' ouput still shows non-dynamic tables out of sync. 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. But, "B" will not send that same change on to "C". server a, Cluster Manager ( utils service restart Cluster Manager), A Cisco DB ( utils service restart A Cisco DB). not been passed from the subscriber to theother device in the The cdr_broadcast actually contains which tables are being replicated and the result. broken, you must know the variousstates of the Real Time Monitoring Ensure that the network connectivity is successful between the The 'utils dbreplication runtimestate' command provides a summary of the validation process.
