3. Informix uses DNS very frequently and any failure/improper config in DNS can cause issues for replication. that the publisher waits for all the subscribers in order tosend equivalent on all the nodes. Processnode table must list all nodes in the cluster. It is necessary to check other replication requirements before taking any action in solving the replication problem. Later examples talk about identifying a corrupt syscdr database. This clears out configuration information from the syscdr database which forces the replicator to reread the configuration files. 0 InitializationStateReplication is in the process of setting To monitor the process, run the RTMT/utils dbreplication !" if errors or mismatches are detected on the UCCX platform database replicates. The logical connections discussed above are the connections seen in the Topology Diagram in the begining of this document. A root node will not pass a replication change on to another root node. CM Hosts, the Rhosts and theSqlhosts are equivalent on all the This state is rarely seen in Confirm that publisher has brought its on syscdr back up (In Cisco Unified Reporting-> Database Status -> Replication Server List confirm that you see the publisher's local connection up. Remove database replication (utils uccx dbreplication teardown) Setup database replication (utils uccx dbreplication setup) Initiate a data repair process for all the databases (utils uccx dbreplication repair all). Replication REPLICATION SETUP SERVER-NAME IP ADDRESS (msec) DbMon? We verify in the report that all of the hosts files look correct. Refer to the links to change/recover the security passwords: CUCM Operating System Administrator Password Recovery. This enables multithreading and improves replication setup time at the slight cost of processing power. Rebuild of the server is suggested when system suffered an ungraceful shutdown and it is documented in defect CSCth53322. the steps mentioned under TheHosts files are mismatched. If no, contact Cisco TAC. 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 you've done this you will need to run the utils dbreplication runtimestate command to monitor the progress. 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. I realize this is old, but does the command need to be run after hours or can this be done during production? The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. +11-12 * 3 min = 6 min, Repltimeout should be set to 21 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. The utils dbreplication runtimestate command shows out of sync or Step2: Put the command "utils dbreplication runtimestate". 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. replication.

We verify in the report that all of the hosts files look correct. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. As illustrated in the figure below, only the publisher's database is writable while each subscriber contains a read only database. 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 problem. The best command to verify DNS is utils diagnose test. Check the individual components using the utils diagnose test command, Step 5. Replication is in the process of setting up. Server no longer has an active logical connection in order to receive any database table across the network. Starting in CUCM 10.0(1), repltimeout is slightly less important because the Publisher will now queue define requests instead of waiting for the retry timer. I choose to ask for the Database Status report as the customer is in a version that has this available. table across the network. Note: Changing this parameter improves the replication setup 09:32 AM. network connectivity and the securitypassword is same on all the 2- Check the services by running the command "utils service list" 3- Run the command and get the output of "utils diagnose test" and see if it fails at any point 4- Run a test for other nodes using "utils network connectivity" on all the nodes Error checking is ignored. This can be used as a helpful tool to see which tables are replicating in the process. Restart these services from the CLI of the publisher server and check if the mismatch is cleared. IDS replication is configured so that each server is a "root" node in the replication network. If the RTT is unusally status again. It runs a repair process on all tables in the . How many servers do you have in the cluster ? Step 4.
