May I assume (should it be obvious?) that the design is such that
system resources can be sufficiently RACF-protected that a user
lacking authority to update those resources can not threaten system
integrity or security by failing to follow proper protocols, but
only the integrity of that user's
Perhaps it is not obvious to some, though obvious to me.
The only valid protocol for such operations as reallocation of space and
compress is to use DISP=OLD (ENQ obtained exclusive).
If you choose to do such operations with DISP=SHR then you get what you
deserve (i.e., it might work but your

It is true that you can increase the size of a dataset that is OPEN by
another address space after removing its ENQ protection, as you have
obviously demonstrated with your experiment.
However, you need to understand that the internal constructs

See my previous reply. The DEB exists in the LSQA of the address space

necessary for the system to find all OPEN instances of the newly
extended data set and then adding the new extent to its particular DEB.

OK, it looks like I missed your ENQ shared condition. On looking back, I
see you just allocated the file DISP=SHR, which would allow you to OPEN
it in another job and then extend it. Of course, you realize that you
