The PowerExchange Listener manages communication between PowerExchange and a data source for bulk data movement or change data capture. You can define a PowerExchange Listener service so that when you run a workflow, PowerExchange on the PowerCenter Integration Service or Data Integration Service node connects to the PowerExchange Listener through the Listener Service. Use the Administrator tool to manage the service and view service logs.
When managed by the Listener Service, the PowerExchange Listener is also called the Listener Service process.
The Service Manager, Listener Service, and Listener Service process must reside on the same node in the Informatica domain.
On a Linux, UNIX, or Windows machine, you can use the Listener Service to manage the Listener process instead of issuing PowerExchange commands such as DTLLST to start the Listener process or CLOSE to stop the Listener process.
If the PowerExchange Listener is running on i5/OS or z/OS, you cannot manage it with a PowerExchange Listener Service. Instead, manage the PowerExchange Listener by issuing z/OS or i5/OS commands or by issuing pwxcmd commands. For more information, see the
PowerExchange Command Reference
You can use the Administrator tool to perform the following Listener Service tasks:
Create a service.
View or edit service properties.
View logs of service events.
Enable, disable, or restart a service.
You can also use the infacmd pwx commands to perform many of these tasks.
Before you create a Listener Service, install PowerExchange and configure a PowerExchange Listener on the node where you want to create the Listener Service. When you create a Listener Service, the Service Manager associates it with the PowerExchange Listener on the node. When you start or stop the Listener Service, the PowerExchange Listener also starts or stops.
