It's really a bad, stomach-wrenching feeling when you hit ENTER on your 
second level system and realize you shut down the first level system 
instead  :-(  Been There, Done That......
 
I do all the attaches and everything else I need to do, then issue a 
PRIVCLASS command to remove all classes  except "G" on the second level 
system's userid.  Then... everything is (hopefully) safe.

Re: MAINTENANCE






Over the course of 30 years of VM systems programming, I and every VM 
sysprog with whom I have worked, have shut down a production system 
once.  There is probably a SHUTDOWN EXEC on almost every VM system in 
the world. 

One thing that I don't understand is why in the world, the SHUTDOWN 
command is ever used in anything except CP.  If I remember correctly it 
is also in RSCS and PVM and I suspect other IBM programs.  It isn't all 
that difficult to shutdown a remote system with either of them.  I've 
done it.
