Subject: RE: [SYSTEM21] Save while Active
We have been performing a save while active for over a year. It kicks off
from ROBOT at 12:01am, we bring the JBA Background jobs down via shut down
programs as well as communications for Future Three. We also bring down
all of our interactive users and start a save while active with *SYNCLIB on
only the necessary libraries.
SAVLIB LIB(AEGINW352 FUTBARCODE FUTBARPRNT FUTCP FUTDTALIB FUTMODS
FUTMAP FUTVRDTA4 OSL@@F3 OSLMODS TLABARCODE TLACS) DEV(TAP01) ENDOPT
(*LEAVE)SAVACT(*SYNCLIB) SAVACTWAIT(120) SAVACTMSGQ(QSYSOPR) ACCPTH(*NO)
We use ROBOT to monitor for message id CPI3712 telling us that the
checkpoint processing is finished, on average about 10 from shutting down
JBA to bringing our JBA production users back on line. We bring production
users on line and perform the necessary Future Three jobs, ie shift, and
after that we bring the remainder of the jobs up. The actual save time
will run for another 45 minutes.
So.. Our manufacturing people are down for a total of about 8 to 10
minutes and our shipping is down for about 18 to 20 minutes. Everything
runs very smooth and wasn't too bad to set up. And yes we have tested
several times with several different libraries, and not necessarily because
I wanted to.
The times are as low as i can get them with out a faster machine or doing
purges. We are running a 620 with 2 gig of memory. The data size we are
saving is as follows and the size is in 1,000,000 bytes ...
(Embedded image moved to file: pic00293.pcx)
ALSO,
We use a 2 Hour limit as well and have had no problems with data integrity.
Train the users not to be in an option when they will be away for an
extended period of time, and yes this does mean beatings!!!! . As for
finance - it doesn't happen often and it isn't hard to recover a session.
Once you understand all the locks and the reasons why subsystems don't come
up you can easily program around it. So, when the system comes down at
night for back ups we still go clear the locks and checking everything via
programs that all is cool. And since it isn't good getting a call at 1am
we make sure everything was cool when we set this all up.

Chris,
Thanks for bringing that up... Your point is completely valid and
accurate.
We've had to resort to public floggings on occasion and users have been
well
trained to not leave posting sessions and maintenance screens unattended...
We don't really have a problem with that any more (knock wood)... More
likely a powerfailure will get us than the inactivity timer these days...
Your point is well taken and anyone would do well to consider it before
actually using the inactivity timer.
Great point...

Jeff,
I am not sure about the wisdom of using the Inactivity Timeout facility
on the iSeries in combination with System21. In fact I have advised
some companies against using it because of the possibility of corrupting
data in S21, especially in the Finance applications. My concern is
that a 2 hour limit could catch someone who leaves a session running
during the day (especially over lunch).
S21 doesn't handle these terminations very elegantly, and if users were
in the middle of posting a transaction strange things can happen. At
the very least it creates a record in the System Manager dumps file and
an error report on OSLDUMPS, which someone ought to be investigating.
This can happen for any number of reasons, including PC or network
problems, power being switched off, etc., etc., and I'd prefer to
minimise the amount of work in checking these "errors".
I don't have better suggestions (other than public flogging for any
users who leave sessions running when they leave the office), but I just
thought I'd raise this issue in case anyone else has any bright ideas.
Chris
