I can think of two things off the top of my head. If there are a lot of people trying to update the table simultaneously you could be getting freelist contention. The solution would be to create addtitional freelists. Another thought is that if you've only got one rollback segment online you could be getting contention for the transaction table in the rollback segment. Solution here is to bring more rollback segments online.

I noticed that this table was the only one with 'CACHE' turned on so I turned it off. Now I am able to update a row, but there is such a perfomance problem that to update 1000 rows will take an hour.

There were no locks, no dba_waits or dba_blockers entries.

I bounced the db and nothing has changed.

Selects work fine.

I'm now looking at performance issues specific to this table.

thanks,

mike

Sounds like it might be a locking issue...check to see if anyone else has that table/row locked. (v$locked_object, v$lock, etc.).

Hi,

I am having a problem updating a table. Using 8.1.6.1 on NT.

I can update other tables owned by user 'BOB'.

All tables were created via IMPORT. Table X 'should' be the same as the rest.

But no one can update table X, owned by BOB.

No errors are returned and no alert log entries are generated. SQL PLus simply hangs.

It doesn't matter if it is 1 record to be updated or 30,000, the same result - nothing.

BOB can select from this and other tables just fine.

BOB can update other tables just fine.

Ideas?

Thanks,

Mike
