RE: backups on AS/400; part2 -- MIDRANGE-L

The attention key could be used to get another command line, if the attention
key program allows it (like IBM's *ASSIST - Operational Assistant.  Just have
to ensure that the user profile has ATNPGM(*NONE).

We're talking about a 1 line CL program here.  Try it and attempt to prove
me wrong, mortal.

By the way, what is the big hairy about the attention key?  I would be more
concerned about the System Request key.  Either one wouldn't hurt this set
up though.

How about hitting the ATTN key after sign on and before the DLYJOB CMD is
invoked?

Yes.

And to verify, change the initial program to one that only does a DLYJOB
and try to hack out of that.

So, let's suppose I create a special SAVEUSER user profile.  It has an
initial
program that prompts the user for the parameters by which the backup should
be
run, including a DLYJOB RSMTIME(x) before the system is ended to a
restricted
state.  The program ends with a SIGNOFF.  The user profile's initial menu
is
*SIGNOFF.  Does that cover all the bases for restricting anyone from being
able to issue a system request #2 "End previous request"?

Writing your won CL's to do this is not as hard as it sounds. Making it
work with the applications you run is the challenging  bit. Integrating it
with management policy is the complicating factor.

Once you know what applications are running, what data has to be saved and
what the timetables are, you can write a program that will accommodate all
this.

IBM has written a program that will save everything - fair enough they have
to. Can you imagine the complications and complexity it would have had to
have to take account of every possible permutation of operational practise
? Essentially they provided the lowest common denominator (at least they
provided that) and did not attempt to solve the other problem. Nor should
they in my opinion, at least as part of the OS. Don;t forget that this
backup running correctly also has to cover IBM's ass and work as predicted
every time.

As to some practical things you can do to improve this stuff - so you
aren't working late doubling as the night operator (is this what happens
<g>) -

Build a CL that will do the saves you want. Make sure by verifying from the
manual it has what you want. The poster Al referred to (Are you saving the
rights stuff ?) is really handy.

If you want the job to delay, build in a parameter to pass as the delay.

If you must have it kicked off from the scheduler, well, one way to do that
is to start a job and make it wait on a data queue before proceeding. Have
something in the scheduler that sends the appropriate data queue response,
indicator, command, whatever. I think you will see where I am going with
that.

As for problems with it, well I attended my first few till I was confident
my software worked, then after that I trusted it with the following caveat:

Always check the logs. Always get the printouts. Always check the last line
of the printouts. Always.

I built in additional logging to my procedures so that there were
additional places that get checked. I also made sure that the other people
that deal however indirectly with the AS/400 backups know what our
expectation is and that and deviation must be bought to my attention. Even
if they are not sure if it different, just something they don't understand
or seems wrong. The backup is sacrosanct and we treat it that way.

You can also check whether the system is in a restricted state with an API,
which will help with the ENDSBS *ALL problem. I like to retrieve a value,
not muck around with message queues as its much cleaner.

There is also no reason you can't return things to an operational state
after the restricted portion of the save is completed. If you write the CL
you have control over this

Hope this provides some food for thoughts
