Re: Lock on command processing program ignored

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

This is our own command and program. I want to make sure only one job
can run it at a time.

There are no messages coming out in the joblog.

I will be trying an ALCOBJ *EXCL in the validity checker. I'm just
curious as to why a locked-exclusive CPP can still be used.
