Re: unable to update rows

Posted By: Art Kagel
Date: Wednesday, 26 December 2012, at 12:22 p.m.

In Response To: Re: unable to update rows (MARK COLLINS)

Mark:

Curiouser and curiouser. You have no attached index keys, no special
columns, only 93 extents (admittedly they are tiny extents besides the
second extent), and fewer than 58,000 pages allocated. A reorg after
setting the table's NEXT SIZE to something reasonable like 10,000 pages
(20000K) would certainly help performance if nothing else, but I see no
reason why this table is returning -136 errors!

As an initial work around, I would actually forgo the usual reorg
techniques and unload, drop, rebuild (with EXTENT SIZE and NEXT SIZE set),
and reload to eliminate whatever quirk in the table's internal structure is
triggering this obvious bug. I would also take a recent archive and sent
it to IBM with a PMR so they can track down the bug. Finally, I would
suggest upgrading to 11.70.<latest> in case this bug was accidentally fixed
in a later release.
