Over the years since dynamic IOCP changes became possible, I have had several occasions to use them. At first I ran into problems of not being able to activate the newly saved IOCDS (RC=88, I believe) because I had somehow or other gotten out of sync. So I created a special machine just for dynamic IOCP stuff, named, obviously, DYNIOCP.
This machine presents a panel, which: - tells me if current status is DYN ON or DYN OFF - allows me to change the DYN status - records EVERY command entered, *AND* its resulting message(s) in a dated log file - allows me to scroll backward/forward through an unlimited number of previous commands - has a PF for FILELIST enabling me to look at log files, etc. So, I can be totally sure what changes I *did* do, and what I did *not*, and can create an IOCP source exactly matching the new hardware setup. I recently had to set up new dasd on the fly, after a long time with no new hardware, and using DYNIOCP made it a breeze! Seeing a successful result to "SET IOCDS_ACTIVE" is a real pleasure. Available on request, of course. (Pre-req: my XFS panel display program) Shimon
