PowerExchange defines the active logs at installation when you run the SETUPCC2 job that is in the RUNLIB library. This job runs the PowerExchange Logger in batch mode to create the EDMUPARM options module and define the active logs to the ERDS.

During archive processing, the PowerExchange Logger automatically defines archive logs to the ERDS.

Also, you can use the DEFINE_LOG command to define the active and archive logs to the ERDS.
