Will setting TRAPMSG (CMS SET command) do the trick for you?

TRAPMSG (STOP dutifully drops the virtual machine into CP Read, but
CONCEAL does nothing at that point.  PMR time?

Can you use TRAPMSG to issue an IPL command.

 Can you use TRAPMSG to issue an IPL command.

Was that a question?
From the TRAPMSG doc, I don't see any way to issue a specific command. 
That sure could be useful for high-availability SVMs - even as a 
poor-man's automation (limited to the messages trapped by TRAPMSG).

It sure could. I hate doing such things as putting IPL or LOGOFF commands on 
the stack.

Getting a CP READ posted does give you the 15-minute FORCE so long as there is 
no SECUSER. If there is one, it ought to be monitoring for VM and CP READS and 
doing the appropriate thing.

Richard Schuh

CONCEAL doesn't stop you from going into application-generated CP READ - 
it recovers only from CP-generated CP READs (e.g. disabled waits).  For 
details, read the usage notes on SET CONCEAL.
