Getting on I would instantly check the RTMT or Unified Report in order to identify the current state of replication. This is similar to the server being in state 4. Navigate to System Reports and click Unified CM Database Status as shown in this image. Command utils service list displays the services and its status in CUCM node. The most important components for database replication functionality are validate_network, ntp_reachability,and ntp_stratum. Ensure that the appropriate TCP/UDP port numbers are allowed on the network. 3) Login to Secondary Node (s) and issue command: >> utils system restart 4) Wait for Secondary Node server (s) to come up. 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 ). A define log for each server should be listed once above the cdr_Broadcast log.

ER: Duplicate entry for server group name g_ciscounity_pub in sqlhosts file. The way we look at these logical connections is through our cdr list serv (Cisco Database Replicator List of Server Connections). Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. If no, contact The best place to see these logical connections we are referring to is from Cisco Unified Reporting Database Status Report. Servers here should have the correct hostname and node id (populated from the process node table). 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. I'll run in before the rooster wakes. If the RTT is unusually high, check network performance. Informative and detailed doc.. Easy to understand. Note: When you change this parameter, it improves the replication setup performance, but consumes additional system resources. In status again. This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts.

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. (*) The command execution example is the same as in (1). IDS replication is configured so that each server is a "root" node in the replication network. My go-to when troubleshooting database replication. However, all of the nodes must be authenticated (ensure that the security password is same on all of the nodes). If you receive Cannot send TCP/UDP packets as an error message, check your network for any retransmissions or block the TCP/UDP ports. Calculate the replication timeout based on Understanding the output of utils dbreplication runtimestate for CUCM. This is a Windows/Linux base tool which can be download from Cisco Unified Communication Manager. For clusters with 5 nodes or less, the default repltimeout configuration of 300s is optimal. I choose to ask for the Database Status report as the customer is in a version that has this available. timeout ). NOTE: THESE COMMANDS SHOULD BE RUN FROM THE PUBLISHER. Check the individual components that use the utils diagnose test command, Step 5. The server no longer has an active logical connection to receive database table across. Cisco Unity Connection Replication not setup. The show network cluster command checksfor utils dbreplication runtimestate Runtimestate command shows the progress of the database status so it can display different Replication Setup for the nodes while it is in progress. Find answers to your questions by entering keywords or phrases in the Search bar above. The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. In 6.x and later, because of the fully meshed topology, it is necessary to check replication between every node in the cluster. DBver& REPL. 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. those issues. Find answers to your questions by entering keywords or phrases in the Search bar above. The common error If theCisco Database Replicator (CDR) list is empty for some nodes, refer to Step 8.

This is likely the best summary of dbreplication I've found yet. necessary to troubleshoot and resolve those issues. In the event the publisher goes down or becomes inaccessible the subscribers will use their local copy of the database. 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. " is " YES ". Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. network. whether the tables match. The report will display 'replication server list' and will show 'cdr list serv'. Refer to this link in order to change IP address to the Hostname for the CUCM. this image. If yes, go to Step 8. Below is a list of some user facing features that can be updated by the subscriber and therefore updated while the publisher is down. 4. case of nodes greater than 8. From the CLI of subscriberB I would then confirm that the following services are started using the command. Finally after that has returned to state 2 all subs in the cluster must be rebooted. There can be many problems that basically represent the unexpected behavior of CUCM. On the Publisher, enter the utils dbreplication stop command. 12:47 PM. 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.
