Jacky,

It depends on what you want to change and the reason for the change. Is
this to prevent space abends or some other reason?

If the items are controlled by DFSMS (Storclas, Mgmtclass, etc.) you can
use
the ISMF panels to alter a data set.
If it is things in a LISTCAT you can see if IDCAMS can help.


Depending on how the data set is allocated at the time, some things may
work
and some may not.

As for space allocation, for VSAM use IDCAMS (so long as the correct
SHAREOPTIONS are in use), for NONVSAM you will need to have control over
the
data set.

Products like the old STOPX37 would intercept allocation process and add
volumes or increase space to prevent (or reduce) SX37 Abends.

Lizette


Is it possible to change the DSCB information of allocated dataset
through
some utility ? Like changing Primary / Secondary quantity ?

Expiry Date etc.
