Home -> Community -> Mailing Lists -> Oracle-L -> RE: Staffware on Oracle - deletes are hanging...
Hi,
I think you're misunderstanding the way these things work. Truncate is
always fairly fast because it does very little work in most cases, simply
resetting the table's HWM and releasing some extents back into FET$.
A delete can have considerable overheads and can bottleneck in many places.
Such things as integrity constraint checking, index maintenance and poor
redo log optimisation can all slow down the operation.
You should watch for wait events during the delete to see where the database
is actually waiting. Also check the alert log file for messages indicating
that you're waiting to checkpoint.
Regards,
Mike Hately

Hi all.
Anyone that is running Staffware out there on Oracle 8.1.7 - please help me
out here.
This is urgent.
We are trying to delete 70 000 rows from a table - via Staffware, so that we
can do a restore - via Staffware.
This seems to take over 10 hours, and still does not seem to complete.
If I do a truncate table it takes a few seconds, but via Staffware it just
hangs...
Any idea's?
Thanks
Clint
