I need to allocate a huge amount of storage to a dataset which already exists. This dataset is not getting created anywhere in the job where i can change the SPACE parameter but just exists with a DISP=OLD in the job. However, yesterday there was a surge in no of records written into this one which the dataset could not handle and got blown up as a result.
I dont want to allocate a fixed storage to this but instead was considering the situation where i can dynamically allocate the space and release the rest of it so that no storage is wasted. Is this possible ?
Thanks in advance,
