Hi All
I have this requirement.

I want to find out if generations are existing for a GDG base specified. Based on if exists or not exists i am to run a particular step in a job.
What i did to solve this problem was:

I used IDCAMS utility and did a LISTCAT LVL('AAAA.BBBB.GDGBASE'), the step gives me a return code of 4 when no generations exists and 0 when generations exists.

Is this solution ok or is there a mor standard way of checkin?

Also i would like to ask one more questions on the same lines, is there any method to find out the number of generations currently existing for a GDG.

rajeshkoratti,

why not not check for 'AAAA.BBBB.GDGBASE(0)' version of the gdgbase? If you have a generation you will get a zero return code else you will get a 12 return code.
