Hi,
We use ALTER command to alter any of the attributes of a GDG...just a doubt...can we reduce the Limit of a GDG once it has been established?
My client side machine do not allow me any alterations on GDGs and hence can not try the same out...so any reference/link with your answer will be really helpful.
In case there are attachements you can mail me @ ***EMail ID REMOVED... Use CODE tag to include mail id***
Thanks & Regards,
Anand Laddha |

Anand,
You need to be cautious reducing limit of existing number of generation... It might cause you lose of data... See the manual for ALTER...
manual wrote: |
LIMIT(limit) :- Used to modify the maximum number (between 1 and 255) of active generation data sets (GDSs) that might be associated with a generation data group (GDG) base.
If the limit is less than the current number of active generations, the oldest generations are rolled off until the new limit is satisfied. Any GDSs that are rolled off by this command are listed showing their new status (recataloged, uncataloged, or deleted).
If the limit is greater than the current number of active generations, it does not cause the roll-in of existing rolled off GDSs. For this function, see the ROLLIN parameter. |
