The Logger Service is an application service that manages the PowerExchange Logger for Linux, UNIX, and Windows. The PowerExchange Logger captures change data from a data source and writes the data to PowerExchange Logger log files. Use the Admnistrator tool to manage the service and view service logs.
If you have the PowerCenter high availability option, you can run the Logger Service on multiple nodes. If the Logger Service process fails on the primary node, it fails over to a backup node.
