The following output media can be allocated instead of the default SYSLOG and JESMSGLG:
SYSOUT
An output class
Note: We recommend that you use an output class (SYSOUT) as the medium for the trace output.
SUBSYS
A subsystem
A dataset
An existing sequential dataset
This dataset must be allocated with disposition SHR. The started task or batch job must have WRITE access to this dataset.
Note: If the dataset becomes full, the system will continue to log data in this dataset, starting from the beginning. This means that data that has been stored up to this point will be lost.
