Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. We now do some other checks to prepare to fix replication. the proper functioning of the database replication are: The validate_network command checks all aspects of the network Cisco Unified Communications Manager (CallManager), View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices. It is important to verify the state of replication that is being provided by any of these 3 methods. case of an unsuccessfulconnection, go to Step 8. Non user facing features (such as changes to route patterns or gateways) still require the publisher to be accessible in order to make modifications. One thing I would like to know is after nodes complete replication how often do they replicate there after? 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. Repair all/selective the tables for database In versions 6.x and 7.x, all servers could show state 3 even if If the Rhosts files are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. 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.

Connected i. Queue: 0 or varying numbers ii. 2. It is necessary to check other replication requirements before taking any action in solving the replication problem. The replication timeout is based on the number of nodes in the If any node has a Check the same and use the Timestamp. REPLICATION SETUP, SERVER-NAME IP ADDRESS (msec) RPC? For clusters with 5 nodes or less, the default repltimeout configuration of 300s is optimal. You can also look in the informix log on that box to confirm this. When we do a utils dbreplication reset all they get done again. Changes in architecture are implemented in later versions to address this limitation. The following table lists each command and it's function. No replication occurs in this state. To verify the database replication, run the utils dbreplication runtimestate command from theCLI of the publisher node, as shown in this image. To check all tables run.

Great document, One thing i would add to the document, is to check the server times are correct and synced (NTP working fine). Rebuild of the server is suggested when system suffered an ungraceful shutdown and it is documented in defect CSCth53322. 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. 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. still in progress. Ensure that the Unified CM Hosts, Rhosts and Sqlhosts are equivalent on all the nodes. Cisco Unity Connection Replication not setup.

Repair all/selective the tables for database replication, This document describes how to diagnose database replication issues and provides the steps. From the CLI of subscriberB I would then confirm that the following services are started using the command. We verify in the report that all of the hosts files look correct. Database replication commands must be run from the publisher. A setup failure might have occurred ifreplication is in this I have Question, If the .rhost file is deleted/corrputed, is there a way to recreate it? A setup failure can occur if replication is in this state for more than an hour. This is not an exhaustive list. all the nodes. Following this command 'utils dbreplication reset all' should be run in order to get correct status information. We verify in the report that all of the hosts files look correct. 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. Database replication can be damaged due to ungraceful shutdowns and they are visible in System-history log. Model, Step 2. Proceed to Step 8, if the status does not change. Repair all/selective tables for database replication, Step 8. In other words, a change made on "A" will be sent to "B" by "A".

Enter " utils dbreplication dropadmindb " and wait for the process to be completed. Stops currently replication running, restarts A Cisco DB Replicator, deletes marker file used to signal replication to begin. in the output and the RTMT state changes accordingly, as shown in DBver& REPL. scratch. The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. This issue can occur because the other servers are unsure whether there is an update to the User Facing Feature (UFF) that has not been passed from the subscriber to the other device in the cluster. That would be covered under the "utils diagnose test" section. 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. Once completed, follow Step 3.

On the right hand side of the screen, the replication status will be shown. "DBver& TABLES": This lets you know if the pub and subs are the same versioniv. All the nodes have the connectivity to each other. 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). However, Unified CM Database Status Report also displays this information as shown in the image. Step 3. Review the Unified CM Database Report any component However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes). This document discusses the basics needed to effectively troubleshoot and resolve replication issues. This command can be run on all subscribers at the same time but needs to complete on all subscribers prior to being run on the publisher.
