Identify obsolete GDG bases

Post by BMS » Wed Sep 25, 2013 3:44 pm

i have a requirement to identify Obsolete GDG bases in a particular region. say for eg the GDG's of my region starts with FMFM.*

using SORT,IDCAMS & REXX i got the list of GDG bases(starting with particular HLQ - FMFM.*)which has no generations .

now from that list i need to seperate the GDG bases which are obsolete(not used for more than 2 months).
please help with your thoughts to proceed this case.

Obviously you need to find the jobs that used these and find out when they were last run. Your scheduler should have the info. However, 2 months is a short time span - it does not cover quarterly jobs let alone annual jobs so BEWARE.

And - a further thought: how about bases that are NOT empty but are unused.

Need to check that also. first thought of identifying Obsolete GDG bases with no generations...

in my region i have totally 13000 GDG's and from that the GDG's with no bases list has 8000...so verifying every job is tedious one...also we usally use symbollic parm in jobs...
any idea.. please suggest

I guess you mean you ahve 13000-ish GDG bases of which about 8000 have no entries. You are going to have to take a list of those empty GDGs into a dataset and then get all your jobs/procedures unloaded into another dataset and start, create a macro to find the base within the unloaded data, create a program to ISPF EDIT the datasets issuing the find for each base and note the results. Lots of other stuff in there that you need to think about but you may even be able to do it with DFSORT.

One of my sites often has gdg bases with no generations and they are NOT obsolete. . .

There are periodic processes (say weekly) that add a +1. At the end of the month, the existing generations are processed and deleted.

That base should Not go away.
Have a good one

That still does not give a clue to identifying the ones that are truly obsolete . . .

If you scan all of the production JCL and look for these names, this may help.

What will be the "cost" if gdg base is deleted and then some process tries to create a +1?

is there any way we can find when(date) was the recent version creation or deletion happened for a particular GDG base
