Hi crm,
you can use the IEBGENR/IDCAMPS to delete another way is if you know the version then go to ISPF 3.4 and you can issue D on the line
Thanks

GDG Versions and Generations are different.
e.g.,
GDG Version 01: HLQ.BASEGDG.G0001V01
GDG Version 02: HLQ.BASEGDG.G0001V02
GDG Generation 01: HLQ.BASEGDG.G0001V00
GDG Generation 02: HQL.BASEGDG.G0002V00
But crn,
I believe that by deleting GDG Versions, they meant deleting the generations only.
With regards,
Souvik |

Souvik, just don't forget that the system only allows for one version for one generation.
crm, I have no idea what the proper answer is supposed to be. The DELETE command should work, as well as the DELETE disposition on a DD statement. |

| To clarify a bit more: a generation can have more than one version, but only one version of that generation may exist at any given time. E.g. G0001V01 can REPLACE G0001V00, G0001V02 can replace G0001V01, etc. |

Pals,
So many replies, but I don't think that the requested solution is provided clearly.
Crm,
Below are two methods of deleting GDGs.
1. The following will delete all versions of a GDG keeping the gdg base. userid.mygdg.base is the gdg base name.
| Code: |
//STEP1 EXEC PGM=IEFBR14
//DD1 DD DSN=userid.mygdg.base,DISP=(SHR,DELETE,KEEP),
|
2. To delete GDG base & all generations if exists by IDCAMS use the the following jcl.
| Code: |
//*******************************************************
//PSTEP04 EXEC PGM=IDCAMS
//*******************************************************
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE 'MY.GDG.BASE' FORCE
/*
//SYSDUMP DD SYSOUT=*
//*
|
Hope this helps,
Thanks,
Phantom |

Hi crm,
As for as i know, the GDG is also like a PS. So we can use IEBGENER utility to delete the GDG version/generation as given by Phantom.

Meena. |

Hi frnd,
Everything is right but i remember that v should give like this in that particular line
//SYSIN DD *
DELETE(MY.GDG.BASE)GDG
/*
OR
DELETE(MY.GDG.BASE)GDG PURGE
OR
DELETE(MY.GDG.BASE)GDG FORCE
AS U NEED. |

Which line are you talking about ? IEFBR14 doesnot require a SYSIN card. And if you are talking about the IDCAMS solution that I gave then it already has that.
Please clarify and whenever you refer to any previous post. Please "Quote" the line which you are referring.
Thanks,
Phantom |

I agree with you. But I didn't understand clearly what you were trying to say.
Were you saying that this line
| Code: |
DELETE 'MY.GDG.BASE' FORCE
|
Should actually be given like this:
| Code: |
DELETE(MY.GDG.BASE)GDG FORCE
|
Thanks,
