Re: IEFU85 question
No. IEFU85 is invoked for cross-memory callers and the caller may well be holding locks. I would guess that very few (if any) z/OS Unix callable services are valid in cross-memory mode and none of them would be valid when caller has locks held. IMHO - it is never wise to do anything clever in IEFU83/84/85 - just save the SMF data that you are interested in a queue or list somewhere where a server subtask can pick it up asynchronously.

Re: IEFU85 question
Personally, I wouldn't even try, even if possible (which I doubt). I'd use the IEFU8x exits to copy the information into a global dataspace (or ECSA area, but I prefer a global dataspace for VSCR reasons). The exit would post an ECB in ECSA. This would wake up a started task (aka daemon) which would process the data. That's a very high level overview. IIRC, it is similar to how CA does tracking with CA-ICOM and CA-7. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

Re: IEFU85 question
Hi Thank you. I wanted to avoid the extra server, but seems to me I can't. I wanted to get informed if a file in some USS path has changed . Funny, the w_ioctl (BPX1OC) also using IPC message queues to notify at file change, but here not very clear how can I find out which file has changed. The application would be an USS server , reading some IPC message queues.
