Hi , I am getting the follwing error, when I tried taking image copy of my tablespace.

DATA SET ALREADY USED FOR PREVIOUS IMAGE COPY

Does n't this error message give a hint about the reason for abend?

If that is the case. then how come the same dataset is created in JCL?
What I need to do now? To recitfy this error?

Hello,

then how come the same dataset is created in JCL?

Please clarify - i do not understand the question.

Why is the process trying to create generation 1 (g0001v00) again? Typically, new generations are created as a (+1) and "the next" generation is assigned?

If this is a gdg, the jcl may need to be corrected to use the next relative generation rather than and absolute 1. It may help if you post the actual jcl.

I have created JCL to take Image copies for a table space, i have taken 5 generations of GDG datasets and deleted the generations again and trying to take the image copies i am getting the above error.

Hello,

Suggest you talk with your dba. You only "undid" 1/2 of the footprints. DB2 still remembers these were already used for image copies.

Why not use the gdg as designed and let the unneeded generations roll of when not needed?
