When i am keeping just step1 and omitting step2, i am not getting this error but when i am putting both the steps and do a scan the it says that
Data set is already catalogued.

I have also changed the DISp to (New,Keep, Delete).
But nothing works.

Hello,

To define a gdg, you only need the IDCAMS step. . .

Check with your storage admins - most places to not create "models" any more.

The IEFBR14 jcl is incorrect, but it should not be needed anyway. . .

Could you please let me know where it is incorrect?

You are trying to allocate 2 things by the same name thats where the error lies

Hi,

Aaru

Meenakshi,

I ran the job that you had posted and it worked fine. No error messages were displayed when scanned (PREPed).

Hi,
you can't build a GDG base and then try to allocate a dataset without using (+1) for the datset name.

Hi Gerry,

I think, She is trying to create 'GDG model' instead of first generation, please suggest if I got it wrong. BTW, I've never tried to create a GDG-model ever, not sure when it was used last across shops but Dick's answer gives me little hint..

Hi Anuj,

What it means by GDG model? Could you please explain?

Hi ,

Here you are creating base GDG and trying to allocate dataset with the same name .
I have tried to delete dataset with the below .

//STEP2 EXEC PGM=IEFBR14
//FILE01 DD DSN=Your file,DISP=(OLD,DELETE)

It ends in JCL error as
STEP2 FILE01 - DATA SET NOT FOUND
STEP2 - STEP WAS NOT EXECUTED.

So try allocating with (+1)s .

MODEL GDG - YUK !!!

They are no longer required if DFsms is installed and tailored correctly.

Can anyone please give me the code to create GDG either through preparing a JOB or through File Aid?

Use this JCL

//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DEFINE GDG(NAME(GDGNAME) -
LIMIT(50) NOEMPTY SCRATCH )
//STEP2 EXEC PGM=IEFBR14
//GENER DD DSN=GDGNAME(+1),
// DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(10,5),RLSE)
//SYSIN DD DUMMY

I have a silly question; Can anyone tell me that the GDG base is treated as a PDS or a PS?

After creating the index when we create the model then it is like a file, so in that case it should be PS, but i just wanted to know more about it, as when i try to get the information about an existing GDG base by typing 'I' against it then i get display as GDG base and i don't get the information about it.
