Don, hello. Why wouldn't you use VDISK for the LOCK file? You could see a performance hit with regular DASD.

We are in the process of migrating to a new CPU. The applications people want to run their test
VSE on the new box concurrently with all the other systems still running on the old box.
After some discussion it was decided that we would just put the VSE lock file on a physical
DASD volume. (Currently it is on a VM VDISK).
However, I remembered a problem I had with a new external lock file in a multiple CPU and
VSE environment 24 years ago. The problem was the result of one of the CPUs having more
than one path to the DASD where the lock file resided.
Is this still a problem? Each CPU here has at least 4 paths to all the DASD.
Thanks in advance,
Don
