Because system saves can only be done from the console,
one of the uses for this product is to remotely control
the console session to run the SAVSYS function.
But this requires putting the system into a restricted
state - i.e. terminating all subsystems - and that
would knock out the session you are signed on to.
So to do this you would need to get the console to
call a program which did the necessary
This program should contain the following elements:
- DLYJOB of e.g. 5 minutes. This will give you
time to sign off your session, or change your mind
(via SysRq/2 - i.e. bringing up the System Request
screen on the console (using the 'S' action) then
going into that screen, then taking option 2 on that
- ENDSBS *ALL *IMMED to put the system into
a restricted state.
- SAVSYS tape-device-name.
- STRSBS for each subsystem to make the system (and
your session) available again.
Alternatively, call the startup program
QSTRUP (or your customised version).
Because this product cannot take control of sign-on
screens (there needs to be a job running on the remote
device) you will need to leave the console signed on
as an authorized user. And of course, a tape loaded!
Make sure that the console session won't be terminated
or disconnected by the QINACTIV and QINACTMSGQ system
