JCL and parameters for Acquire/DASD in Cyclic Mode

Member (HLQ).AZDvvvv.JCLLIB(ACQDASDC) contains JCL similar to the following.

//ACQDASD EXEC PGM=ACQDMON,REGION=6M
//STEPLIB DD DSN=APF.LOADLIB,DISP=SHR
//ACQDWK01 DD UNIT=3390,SPACE=(TRK,(1,1))
//ACQDWK02 DD UNIT=3390,SPACE=(TRK,(1,1))
//ACQDWK03 DD UNIT=3390,SPACE=(CYL,(2,5))
//SYSIN DD *
MODE=C CYCLIC MODE. MODE=S IS SINGLE SHOT MODE
* (SEE MEMBER ACQDASDS FOR SAMPLE JCL)
INT=6H INTERVAL BETWEEN SNAPSHOTS. CHOOSE FROM
* 30M 60M 1H 2H 3H 4H 6H 8H 12H 24H 1D
SMF=188 SMF RECORD NUMBER, 128 - 255
LEVEL=V VOLUMES AND STORAGE GROUPS. LEVEL=S FOR
* JUST STORAGE GROUPS
VOL=(ABC*,DE*,FGHIJK,...) OPTIONAL, LIMIT VOLUMES PROCESSED
SG=(PROD90*,IMS*,QATEST,...) OPTIONAL, LIMIT STORAGE GROUPS
* N.B. IF VOL= AND SG= PROVIDED, A DISK MUST GET
* PAST *BOTH* FILTERS
/*

In this example, the SMF record number will be set to the default of 188, records will be created every 6 hours, and volume and storage group data will be recorded for all disks that match both the volume and storage group filters. No dataset groups are being created.

If the SYSIN stream contained this :

SMF=193
INT=12H
LEVEL=S
POLL=SMF
DSG=*HLQ

then Acquire/DASD will write SMF records with an id of 193 every 12 hours. This data will contain only storage group-level information for all online disks. ACQD­MON will determine its polling value by dividing the SMF timeout value by 2. If the DCOLLECT data contains type A and D records about active datasets then data for each high-level qualifier will be aggregated up and written out.
