Listener Service Restart and Failover

Listener Service Restart and Failover

If you have the PowerCenter high availability option, the Listener Service provides restart and failover capabilities.
If the Listener Service or the Listener Service process fails on the primary node, the Service Manager restarts the service on the primary node.
If the primary node fails, the Listener Service fails over to the backup node, if one is defined. After failover, the Service Manager synchronizes and connects to the PowerExchange Listener on the backup node.
For the PowerExchange service to fail over successfully, the backup node must be able to connect to the data source or target. Configure the PowerExchange Listener and, if applicable, the PowerExchange Logger for Linux, UNIX, and Windows on the backup node as you do on the primary node.
If the PowerExchange Listener fails during a PowerCenter session, the session fails, and you must restart it. For CDC sessions, PWXPC performs warm start processing. For more information, see the
PowerExchange Interfaces Guide for PowerCenter
