Question:

Do all "extend file" operations consume the same amount of quotas ?

Do "extend file" operations consume more reources if the disk is
fragmented and each extent results in a lot of different fragments being
allocated to the file ? (versus a single extent being made from
consecutive blocks on disk). ?

Is it possible that a very large default file extent quantity might
consume more quotas than a smaller one ?

Is it possible that after many extents, adding an extra extent might
consume a lot more resources ?

Perhaps the original poster might wish to give some details on how big
DUA510FUL.LOG;202 gets, and post a DIR/HEADER

That's one reason why I originally asked if to extend a file you need
contiguous space.

You don't need contiguous free space to avoid the creation of
extension file headers. What you need to avoid that is to be able to
map few enough extents for your file so that the primary file header
doesn't fill up. While contiguous free space larger than your file
*is* sufficient, it is *not necessary*.

The backup finally worked. I added some steroids to the quotas for the
account (system). Actually just beefed them up by 10-15% over what I
posted yesterday.

I still be it was FILLM or DIOLM.


Someone asked about CHANNELCNT - that was set to 1000.

I also created a new batch queue (also without WSxxx quotas) as the
previous batch queue. Then I moved the output to a new disk that had a
couple of million blocks of free disk space where the old disk only
had about 100K free space.

Here's an dir of the failed log file sizes:
DUA510FUL.LOG;202 8480 3-OCT-2007 12:18:05.95
DUA510FUL.LOG;201 5760 2-OCT-2007 12:06:59.65
DUA510FUL.LOG;200 928 1-OCT-2007 20:00:37.29
DUA510FUL.LOG;199 4224 29-SEP-2007 19:43:36.24
DUA600FUL.LOG;190 1 3-OCT-2007 14:38:23.66
DUA600FUL.LOG;189 896 2-OCT-2007 23:03:23.97
DUA600FUL.LOG;188 1 29-SEP-2007 23:04:06.9

Here's a dir of the log files from last nights successful backup:

DUA510FUL.LOG;1 15588 4-OCT-2007 16:11:47.05
DUA600FUL.LOG;1 18672 4-OCT-2007 20:47:35.6

I'm not sure what finally did the trick, and I don't like using a
shotgu approach, but I'll take the results. When things settle down,
I'll back off the steroids on system's account and see if I can
trigger it to fail.

Thanks for all your help and suggestions folks. I've had problems on
three system simultaneously, so it's been a blast for the laast week
or so!
