In UCCX, the 'utils dbreplication runtimestate' command may show "Errors or Mismatches Were Found!! Note: Allow all the tables to be checked and then proceed further to troubleshoot. Once it is generated, download and save the report so that it Step 2. After all subscribers have been defined we then wait the repltimeout (Can check from show tech repltimeout) it will then do a broadcast file that actually pushes the replicates across. It is essential that the NTP stratum (Number of hops to the However, you can verify whether the DNS is configured and functions properly when you use these commands: If the DNS does not function correctly, it can cause database replication issues when the servers are defined and use the hostnames. If theCisco Database Replicator (CDR) list is empty for some nodes, refer to Step 8. (ID) & STATUS QUEUE TABLES LOOP? order to avoid any databasereplication issues. 'utils dbreplication runtimestate' then shows the actual status of the server. 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. If no, contact Cisco TAC. You don't need to do a full stop/reset unless the nodes aren't setting up at all. You must check the status for every node. 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. "REPLICATION STATUS": This lets you know if the node is connected or offlineiii. Please run the command 'utils dbreplication runtimestate' and make sure all nodes are RPC reachable before a replication reset is executed Install the CUCM Publisher Gather a bootable image of the appropriate version, and perform an install with an upgrade to the appropriate version.
