The PowerExchange Listener Service is an application service that manages the PowerExchange Listener. The PowerExchange Listener manages communication between a PowerCenter or PowerExchange client and a data source for bulk data movement and change data capture. The PowerCenter Integration Service connects to the PowerExchange Listener through the Listener Service. Use the Administrator tool to manage the service and view service logs.
If you have the PowerCenter high availability option, you can run the Listener Service on multiple nodes. If the Listener Service process fails on the primary node, it fails over to a backup node.
