DSGREM=SYSTEM Anything not in above DSGs = 'SYSTEM' With these parameters then Acquire/DASD will not require APF authorization and will not call IDCAMS or pass records directly to SMF.
It will expect that file //ACQDWK03 already contains suitable DCOLLECT data. It will write SMF-style records to DDNAME //SMFOUT that are ready for use by Acquire. These will have an SMF record id of 188 (the default).
The data will contain storage group-level information and 4 dataset groupings (ATHENE, DB2, USER and SYSTEM). Group SYSTEM will hold anything not accounted for by the other 3 groups. The data will be associated with an interval of one hour, ending at the time of the DCOLLECT records.
The //SMFOUT file does not need DCB attributes as these are provided by the ACQDMON program, although you may override the BLKSIZE if you want to change it to a specific value rather than let it be chosen by z/OS.
