Save while active was: Logon during night backup on tape

[rob@xxxxxxxxx]

There are a few options to start save while active.  You really need to 
RTM.
Using *LIB or *SYNCLIB will require the users exit for a brief time while 
you do the "checkpoint processing" (again RTM).
Using *SYSDFN will not.  HOWEVER, if you use *SYSDFN and if your 
applications do something like write to a order header file and an order 
line and update the item warehouse file on the press of a single enter key 
it is possible that part of that transaction will be on the save (like the 
order header part) and the other part may not (like the order line and the 
item warehouse).  What will happen is that your user department will 
insist on using *SYSDFN and that is what you will choose.  We had our 
outage of the data library down to a few minutes and that still wasn't 
acceptable - insisted on no outage at all.  Therefore it's not necessary 
that the backups be usable in a restore (sarcasm intended).
