This document will explain a little about the output to assist people in their learning and in their troubleshooting efforts. In versions 6.x and 7.x, all servers could show state 3 even if Calculate the replication timeout based on the number of nodes in the cluster. 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 This is an important step. Saved me hours of extra work. Below is the /etc/hosts as displayed Verified in Unified Reporting. In the output, ensure that the Cluster Replication State does I choose to ask for the Database Status report as the customer is in a version that has this available. 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 parent reference clock) must be less than 5 or else it is deemed unreliable. The nodes are scattered over the Wide Area Network (WAN): Ensure If the RPC hello does not work for a particular node: - Ensure the network connectivity between the particular node Refer to the sequence to reset the database replication for a particular node: In case you reach Cisco TAC for further assistance, ensure that these outputs and the reports are provided: For further information refer to the links: Understanding the output of utils dbreplication runtimestate for CUCM, Troubleshooting CUCM Database Replication Linux Appliance Model. Check the connectivity If any errors/mismatches are discovered, they are shown in the output and the RTMT state changes accordingly, as shown in this image.

Based on the version of CUCM in use you may see the following: i. Following this command 'utils dbreplication reset all' should be run in order to get correct status information. Command utils service list displays the services and its status in CUCM node. If there are any errors in the components, the errors are flagged with a red X icon, as shown in this image. than 5 or else it will deem it unreliable. Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. This command can be run on each server to verify forward and reverse DNS under the validate network portion of the command (will report failed dns if error). Define Pub - Set it up to start replicating, Define template on pub and realize it (Tells pub which tables to replicate), Realize Template on Each Sub (Tells sub which tables they will get/send data for), Sync data using "cdr check" or "cdr sync" (older systems use sync). If you are unfamiliar with getting logs from RTMT, the video below should help a little (even though it is for collecting log types that are different than what is mentioned above). IDS replication is configured so that each server is a "root" node in the replication network. Find answers to your questions by entering keywords or phrases in the Search bar above. 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. It runs a repair process on all tables in the replication for all servers that are included in the command. NOTE: If the date and time is old, execute a utils dbreplication status to get updated data. Refer to Step 5. The full list of user facing features is located on the following slide. New here? Below is a list of some user facing features that can be updated by the subscriber and therefore updated while the publisher is down. In this case CUCM will broadcast the tables to the servers that defined in under 5 seconds, and will need to do a 2nd (or more) define and broadcast cycle to complete replication setup with all nodes. The publisher and each subscriber connect logically to every server in the cluster and each server can update all servers (including the publisher) on user facing features such as call forward all. 3.

Ensure that both servers are RPC reachable column = YES). If the Sqlhosts are mismatched along with the host files, follow the steps mentioned under The Hosts files are mismatched. the steps mentioned under TheHosts files are mismatched. states of the Real Time Monitoring Tool (RTMT) for the replication. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. The common error 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. We'll assume you're ok with this, but you can opt-out if you wish. Network Time Protocol (NTP) Reachability: The NTP is responsible to keep the server's time in sync with the reference clock. Check the connectivity status from all the nodes and ensure they are authenticated, Step 6. "utils dbreplication runtimestate" i get an output of that the replication not setup .
