I don't see this as dynamic vs. static. It's about TSO vs. non-TSO. The authority to mount a tape has always been associated with each individual userid. It's an attribute of the userid in UADS. It's a profile in the TSOAUTH class to which the userid must have READ access. 'Foreground' or 'background', mount must be authorized by userid.
The historical basis for this requirement is not hard to guess. Imagine a time when tapes were handled by people scrambling around on roller skates. A TSO user could finger-check a data set name and send a tape jockey hurtling across a cavernous room to grab a volume not even wanted; meanwhile the user is stuck on the clock wondering why the computer went dead, hollering at the help desk about terrible response time. I would have disallowed tape mounts then. They're still disallowed now by default. Just understand that if your personal userid acquires mount authority, you might become the user described above. . . .

Because it's dynamic. For static allocation the Initiator can sort things out before running the job. Now, it's possible that you have a business case to justify a requirement, but it had better be god, because doing it is going to be a lot of work. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
