Specify the settings required for collecting event logs. The method used to specify the settings depends on whether the system logger service is used.
Do either of the following:
-
To output event logs to the log stream by using the system logger service, perform all the sysplex setup procedures for using the DASD-only log stream for the system logger service described in the IBM manual MVS Setting Up a Sysplex.
-
To output event logs to the MAR log dataset without using the system logger service, create a log dataset before executing a MAR program.
