Still a little fuzzy on this.
I ran this:
//TZFBR14 JOB CLASS=S
//STEP1 EXEC PGM=IEFBR14
//JUNK DD DSNAME=SYS2.DSCB,DISP=(NEW,CATLG,KEEP),
// SPACE=(TRK,(0)),
// UNIT=DISK,VOLUME=SER=D90300,
// DCB=(BLKSIZE=1000,LRECL=100)
According to your response this is not a model DSCB, but a model dataset.
In z/OS V1R3.0 DFSMS: Using Data Sets:
****************************************************************************
3.9.5.1.2 Creating a Model DSCB
You can create a model DSCB on the volume on which your index resides.
Restriction: You cannot use a model DSCB for system-managed generation data
sets.
You can provide initial DCB attributes when you create your model; however,
you need not provide any attributes now. Because only the attributes in the
data set label are used, allocate the model data set with SPACE=(TRK,0) to
conserve direct access space. You can supply initial or overriding
attributes creating and cataloging a generation. To create a model DSCB,
include the following DD statement in the job step that builds the index or
in any other job step that precedes the step in which you create and
catalog your generation:
//name DD DSNAME=datagrpname,DISP=(,KEEP),SPACE=(TRK,(0)),
// UNIT=yyyy,VOLUME=SER=xxxxxx,
// DCB=(applicable subparameters)
****************************************************************************
So I am confused... How do you define and use a model DSCB?
