The main concern with save while active on an *ALLUSR is when you use
any synch point except *LIB. *SYNCLIB and *SYSDFN may take a LONG time
to reach a synchronization point with all of the libraries on the system.
If you use *LIB as the save while active synchronization point you
should not have any issues, I do it all the time.
I also use the technique you mention with two control groups, one for
restricted state for what ever is needed there, then bring the system
back up for use and start a save while active on the other libraries.
I use a control language program to do it so I can manage the shut down
and start up properly.

Another thought I had was to put the *SAVSYS in one control group
(restricted state), everything else in another control group (not
restricted), and run them back to back. This might be trickier, though,
the first control group has to finish before the next one starts. Idon't

writing. Also, since I want everything on a single tape, I need to make
sure the 2nd control group doesn't clear the tape.
