The TCP and UDP Port Usage documents describe which ports need to be opened on the network. 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. We verify in the report that all of the hosts files look correct. Step 8. Check the same and use the Timestamp. image. 2023 Cisco and/or its affiliates. Introduced in 7.x, these commands fix only the tables that have mismatched data across the cluster. If there are any errors in the components, the errors will be *Note*: Publisher define not listed here. The documentation set for this product strives to use bias-free language. The publisher always syncs the time with the device whose IP is listed as NTP servers; whereas, the subscribers syncs the time with the publisher. Later examples talk about identifying a corrupt syscdr database. The best command to verify DNS is utils diagnose test. New here? However, you can verifywhether the DNS is configured and You can also check the output of file list activelog cm/trace/dbl date detail. theCLI: A Cisco DB ( utils service restart A Cisco DB ). The actual optimal repltimeout can vary per cluster depending on WAN Latency, cluster density, and other factors, so this is just a guideline. If any errors/mismatches are discovered, theyare shown We verify in the report that all of the hosts files look correct. Repair all/selective the tables for database Your email address will not be published. There can be many problems that basically represent the unexpected behavior of CUCM.

And also try to get this below fixed. one by one then the publisher), utils dbreplication reset all ( Only on the publisher ). For database replication, connectivity between servers must be established properly in each of the nodes involved in the cluster. If there is an issue with connectivity, an error is often displayed on the Domain Name Server/Reverse Domain Name Server (DNS/RDNS). Thus the recommendation to the customer would be to follow the most basic process that fixes about 50 percent of replication cases. To check all tables run. Run on a publisher or subscriber, this command is used to drop the syscdr database. 08:29 AM Cisco Unity Connection Replication not setup. Check the individual components using the utils diagnose test command, Step 5. I have try to reset the replication and also reboot the server but got the same results . If the RTT is unusually high, check network performance. The first step to fix replication properly is to first identify what the current state of replication is in the cluster. (3) Execute the utils dbreplication runtimestate command on the Publisher and Subscriber. The replication timeout is based on the number of nodes in the cluster: The replication timeout (Default: 300 Seconds) is the time that the publisher waits for all the subscribers in order to send their defined messages. Each subscriber must reach Publisher and other subscribers included in the cluster network connectivity result must be completed successfully. This command only triggers the check of the dabatase status. This can happen because the other servers are unsure if there is an update to a user facing feature that has not been passed from that sub to the other device in the cluster. Do we require these commands ??? Model, Step 2. 2. If you recieve Cannot send TCP/UDP packets as an error Verify that " RPC? In the report the information I find is the following. IntroductionSteps to Diagnose the Database ReplicationStep 1. Servers here should have the correct hostname and node id (populated from the process node table). 1: This lets you know the last action performed and the time of the action. 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. 09:20 AM Logical connections are established but there is an unsurety You don't need to do a full stop/reset unless the nodes aren't setting up at all. Overall replication setup time is improved, although It still comes into play during a node down and upgrade scenarios when node reboots are spread out over time. I have Question, If the .rhost file is deleted/corrputed, is there a way to recreate it? This enables multithreading and improves replication setup time at the slight cost of processing power. 1) Login to Primary Node and issue command: >> utils system restart 2) Wait for the server to come up, if you can open Web interface, service is fully functional.
