Mike,

Is your Mon-Fri save performed in a restricted state, or are you using
save-while-active? If SWA, could there be something running
concurrently with the save on the days that its duration is
extended...thus imposing some level of resource contention?

Steve

subject: RE: Longer backup after an IPL

The script does the same backup process every night Mon-Fri. Weekends
are different since we are not open for business and not here to change
tapes. The script does a save of security data, configuration, all
non-system libraries except our test libraries, all of the IFS. We IPL
every Sunday AM and savsys once a month. The only time we do a GO SAVE
21 is just before an upgrade or OS or hardware.

Wouldn't it be odd if a save of an object caused it to be decompressed?
What would be the purpose of doing compression if on every save
(which every object on the system should be saved at least once a month)
the object was decompressed.

Hi Mike

What does the backup script do ?

Seems to me that a good place to start would be a compare of the joblogs
on
the IPL backup and another one to account for the differences.

If the differences is just in the save operations could you do the
DSPOBJD
before each of them and compare the objects and sizes being saved? This
will
tell you if for instance something is getting compressed and then the
first
save caused it to be uncompressed (this is a complete shot in the dark).

If I really had to just guess I'd look for a weekly housekeeping job
that
runs weekly the day after the IPL runs. Don't forget to check the GO
ASSIST/CLEANUP settings.

Regards
Evan Harris

Just a followup for the archives....

Last night was the first backup since our IPL followed by the DSPOBJD of
the
entire system. No change in the length of the backup.

First backup after an IPL takes from 3:30 until about 7:20. Rest of the
week
is 3:30 until about 6:45.
