pvrajesh31,
Is the GDG you are trying to rename a DASD gdg or a Tape GDG ? If the GDG is on a tape then you cannot rename it as name of the DSN is written on the tape label.
Why not simply
a. Define the new GDG base.
b. Copy the datasets one at a time to the new GDG base.
c. Delete the old GDG datasets.
d. Delete the old GDG base.
Another alternative is
a. Create the New GDG base.
b. Run the following JCL to rename the GDG
| Code: |
//STEP0100 EXEC PGM=IKJEFT01
//SYSTSPRT DD SYSOUT=*,DCB=BLKSIZE=121
//SYSTSIN DD *
RENAME 'your.old.GDG.G0001V00' 'your.new.GDG.G0001V00'
/*
|
However I am not sure that the new GDG's will be linked to the new base. so test it out first. RUN LISTCAT ALL command on the new GDG base and see if it pulls the version names also
Hope this helps...
Cheers
Kolusu

Kolusu,
They are still linked.
I created a GDG base and allocated a dataset using 3.2 with GnnnnVmm suffix and then wrote a copy step taking the GDG base as the input dataset. This step copies the content in the GDG generation.
