GDG when LIMIT has reached

Hi,

Its not same old question.

But the problem I am having is:

I am having a GDG having limit as 2 and following is the way I am using and accessing GDGs...

STEP01

GDG1 DD DSN=MY.GDG(+1),DISP=(NEW,CATLG,DELETE)

STEP02

GDG2 DD DSN=MY.GDG(+2),DISP=(NEW,CATLG,DELETE)

STEP03

GDG3 DD DSN=MY.GDG(+3),DISP=(NEW,CATLG,DELETE)

STEP04

GDG1 DD DSN=MY.GDG(+1),DISP=SHR

STEP05

GDG2 DD DSN=MY.GDG(+2),DISP=SHR

STEP06

GDG3 DD DSN=MY.GDG(+3),DISP=SHR

The option used while creating GDGs is NOEMPTY.

Can anyone help me on this. Thanks in advance.

is there something/somebody preventing from changing the gdg limit ??

depending on the gdg creation options older generation might disapperar/scratched when creating a new one

or review Your gdg usage logic

Well, what exactly is your problem. You have shown the code but not the problem.

What is it that you want to know or need help with.

I want to know that what will happen in above case. Will the version created in step STEP03 will overite the GDG created in STEP01.
If yes, then what would happen to STEP04 and STEP06.

It is not like that I cannot increase the LIMIT. But it is my query what will happen in above case.

why don' t You run a simple test like

define a testgdg base
allocate in the way you want to know about,
to make the test complete repro in each generation a simple line
( REPRO INDD(SYSIN) OUTDD(GDGDD) )

list the catalog

and let us know the result

what You ask for needs a deep digging in the manuals,
and apart that each one of us never created gdgs with a limit less than the number of generations referred in any jcl
