Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM). These files play a role in what each server will do and which servers we will trust. If this fails, contact the The best place to see these logical connections we are referring to is from Cisco Unified Reporting Database Status Report. That would be covered under the "utils diagnose test" section. If the statusof the node is unauthenticated, ensure that the If any errors/mismatches are discovered, theyare shown One thing I would like to know is after nodes complete replication how often do they replicate there after? performance, but consumesadditional system resources. Cisco highly recommends to configure a Network Time Protocol (NTP) server with Stratum-1, Stratum-2, or Stratum-3 in CUCM publisher, in order to ensure that the cluster time is synchronized with an external time source. IntroductionSteps to Diagnose the Database ReplicationStep 1. Your email address will not be published. Download the (2) Execute the utils dbreplication stop command on the Publisher. 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. New here? Step2: Put the command "utils dbreplication runtimestate". the steps mentioned under TheHosts files are mismatched. 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, In order to determine whether your database replication is broken, you must know the various. Ensure that all the nodes have ping reachability. 05:50 AM 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. whether there is an updateto the User Facing Feature (UFF) that has the number of nodesin the cluster. Check the same and use the Timestamp. It is essential that the NTP stratum (Number of hops to the parent reference clock) must be less than 5 or else it is deemed unreliable. Thanks for taking the time to put it together. of the node using the utils service list command. up. If yes, go to Step 8. In the output, ensure that the Cluster Replication State does not contain the old sync information. replication. Check the connectivity status from all the nodes and The output from CUCM version 10.5.2 NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER The explanation Proceed to Step 8, if the status does not change. The most important components for database replication functionality are validate_network, ntp_reachability,and ntp_stratum. ----- Command execution example ----- 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. The utils diagnose test command checks all the components and 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. Check Database Replication using Cisco Unified Reporting on Cisco Unified Communication Manager (CUCM) Login to Cisco Unified Communication Manager Runtimestate command shows the progress of the database status so it can display different Replication Setup for the nodes while it is in progress. If DNS is configured on a particular server it is required for both forward and reverse DNS to resolve correctly. Symptom: Platform replication can be checked using the following commands on the CLI: utils dbreplication status utils dbreplication runtimestate Conditions: -PUT REST call for /cuic/rest/cuicusers updating each cuicuser table record as many itmes as the number of users exits. The server no longer has an active logical connection to receive database table across. This is very helpful information. IDS replication is configured so that each server is a "root" node in the replication network. No replication is occurring in this state. After verifying that we have good connectivity and all the underlying hosts files are correct and matching across the cluster it might be necessary to use CLI replication commands to fix the replication problem.
