The PowerExchange Logger for z/OS requires entries for active and archive logs in the emergency restart data set (ERDS) to access the log data sets.
Use the DEFINE_LOG command to define active and archive logs to the ERDS.
Also, PowerExchange defines the active logs at installation when you run the SETUPCC2 job in the RUNLIB library. This jobs runs the PowerExchange Logger in batch mode to create the EDMUPARM options module and define the active logs to the ERDS.
