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 representing that OPENed data set to the

Gil: See my previous reply. The DEB exists in the LSQA of the address space that has the data set OPEN. In order to do what you ask, it would be 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. How it

Paul: 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 violated the purpose of the exclusive ENQ by updating the data set in
