Database Replication

The CUCM process that copies configuration data from the publisher to all subscribers so each can process calls independently.

Definition

CUCM uses Informix database replication so every node has a local configuration copy. Broken replication causes symptoms such as phones not picking up changes or inconsistent behavior between nodes. Administrators check status in RTMT or with utils dbreplication commands and can repair or reset replication when needed.

Example

utils dbreplication repair all fixes table mismatches after a network partition between nodes.

Exam tip

Replication state values matter: 2 means good; 0, 1, 3 or 4 indicate problems or setup in progress.
