Hi,
I've a GDG base having 5 generations, is there any way to delete all of them in a single go using some utility in JCL? Please advise.

Robert - I might be wrong as there is some ambiguity in the post from OP, however I think he wants to delete the generations and want to retain the base, possibly?

IDCAMS can delete all generations of a GDG and leave the base alone. In fact, my usual JCL to get rid of a GDG does two DELETE commands -- the first gets rid of all the generations, the second gets rid of the GDG base.
Code: Select all
DEL PGMR.UPSTREAM.DOM1.BACKUP.* PURGE
DEL PGMR.UPSTREAM.DOM1.BACKUP GDG

Removing the egg from face slowly...
I had this IEFBR14
thing in mind and missed on the wild-card as part of parameter to IDCAMS:
Code: Select all
//STEPXXXX EXEC PGM=IEFBR14
//DELGDGS DD DSN=&ID..MY.GDG,
// DISP=(MOD,DELETE,DELETE),UNIT=SYSDA,
// SPACE=(CYL,(1,0))
//*

Thanks for the kind words Sanjana - it was a "self-talk", actually. And I realize that I should not have done this while having the fingers on key-board!
