Problem with ONBAR: unusually slow on IDS 11.50.FC

Posted By: Khaled Bentebal
Date: Wednesday, 23 February 2011, at 5:52 p.m.

Hi,

A client of ours is runnning IDS 11.50.FC5 on AIX and is facing a
problem with a backup running ONBAR.

It runs fine on several instances on different machines, but is very
slow on one instance. All of the instances are setup the same way along
the same model and the same ONCONFIG.

ONBAR runs a particular query before performing the backup:
*select ( sum ( npused ) ) from sysdbspaces as D , sysptnhdr as P where
D.dbsnum = TRUNC ( P.partnum/1048576 ) and name = ? *

This query goes on for ever (*few hours*). We tried to run a query on sysptnhdr by itself and sysdbspaces also by itself. It seems that the query on sysptnhdr is very very slow. The same query runs very fast (instantanious) on the other instances.
We tried to rebuild the sysmaster databse, but nothing came out it.

Here is more info on this session: any ideas ?
