Re: Second level VM systems

[Jim Bohnsack]

We've talked about this before and I think that I mentioned or complained, at least 10 years ago, that SHUTDOWN should not have ever been permitted in any IBM program but CP.  SHUTDOWN is used in RSCS and, I think, PVM.  I know that I've SHUTDOWN CP "one" time when I thought I was talking to RSCS.  Every systems programmer with whom I have ever worked has shutdown CP "once".

At one time, we have all shutdown the production VM system when we thought we were on test. Good news is that z/VM 5.4 included a SYSTEM option on SHUTDOWN. An option in SYSTEM CONFIG decides if it is required or optional. If your test image and your production image have the same System_identifier, then you will find the safety net is there, but is laying directly on the ground. Be careful.
