RE: End Day Times

["Allen, Stu" <sallen@xxxxxxxxxxxx>]

I can't help you with changing dayend's initiation time, but there's a
couple of things you may be able to do to speed your existing dayend
routines up. (apologies if you have already done these!)

1. End subsystems & background jobs that you don't need up during overnight
processing, particularly those with their own memory pools (like
QINTER,QSPL).  This'll put more memory in your base pool for batch jobs and
can help a lot.

2. Put a job name for each job rather than leaving it blank. (most std
functions do this automatically)  This will run it in batch, rather than
interactively, which is more efficient on most modern machines, particulary
if you've done (1) above.

3. Tinker with your backup strategy - there may be libraries (display files,
sources, test libraries) that only change at set times (like when applying
ptf's) or are not critical, and therefore can be saved manually "as and
when".
Also, what are you currently backing up onto ?  If your business is
beginning to work later and start earlier, it may be worth budgeting for a
faster backup solution.  Alternatively, if there's no money in the pot, but
you have plenty of disk, you could save to save files, and copy these to
tape once the system is back up.
Lastly you could consider save-while-active.  It is difficult to set up, but
done properly it can make the time that the system is unavailable due to
backup down to 10 minutes  or so..

4. Lastly, and most importantly, have a close look at the time taken by each
of your jobs.  You may find that there's one or two that take ages.  If you
delve a bit into what they actually do, you may find a bespoke logical file
helps the runtime, or in the case of some of the more badly coded jba
programs, a complete overhaul by a decent programmer. 

For the record i have 193 jobs in dayend, 85% running every night.  My
system is a 720/2061 with 1792mb memory and 51% used of 109gb dasd.
Including a full save of *allusr libraries, my overnight routine takes just
under 3 hours.  However i have a Magstar 3570 tape drive, that means my
backup is only 1hr 5mins of that (best thing i ever bought).  


Regards,
Stuart
