Dear "system mamager",
You have given very little to work from. Is the query a SELECT, UPDATE,
INSERT or DELETE? Can you produce explain plans for the query on both
systems? What made you consider disabling the primary key on production
(this sounds like a bold / crazy move, but I wonder why you considered it)?
Are data volumes anywhere near the same on production and test? Is the
query something that is impacted heavily by data volume? Are both
databases analyzed / have stats for all relevant objects?
Regards,
Mark.

Please respond to
ORACLE-L
Dear List,
I have a very strange query:
The table, data, indexes, constraints are set up exactly same
The query was running ok in the test database but paused the production
system.
It is also running ok in production if the primary key disabled.
Any ideas? Any input will be greatly appreciated.
