Hello,
I have a question on GDGs
We have a GDG data set GDG.DSNAME.G0001V00 and append data into
this data set throughout the day.
We then run a batch job where we do the following:
1. Read GDG.DSNAME(0)
2. Delete GDG.DSNAME(0) as follows
//DELETE EXEC PGM=IEFBR14
//DD1 DD DSN=GDG.DSNAME(0),
// DISP=(OLD,DELETE,DELETE)
3. Allocate a new GDG.DSNAME(+1) as
follows:
//ALLOC EXEC PGM=IEFBR14,COND=(4,LE)
//DD1 DD DSN=ISM.SMF.ZHAD011(+1),
// DISP=(NEW,CATLG,DELETE),UNIT=3390,
// SPACE=(CYL,(50,50))
The ALLOC step actually allocates GDG dataset GDG.DSNAME.G0002V00
Besides changing SMS or running two batch jobs, is there any way to
completely delete GDG.DSNAME(0) and allocate GDG.DSNAME(+1) where
GDG.DSNAME(+1) will remain with the name GDG.DSNAME.G0001V00
