Increase space for an allocated VSAM dataset.

Post by Barbie Girl »

Hi,

Is it possible to increase the space for an already allocated VSAM dataset? I do not find a way to do it? Is it not allowed? Please suggest.

 If the dataset has a secondary allocation, it will automatically add extents as needed until the disk volume is full.  If not you can use ALTER.

Clarification: if you mean to increase the PRIMARY space for an already allocated VSAM data set, then the only way to do that is to do a DELETE / DEFINE in IDCAMS.
