Hi,
We are running a query on our DB and even when there is nothing else
running on a DB, the query takes different time. Few times it will
process 300 records/second and then go back to 10 records/second. There
are no Oracle errors or alerts in the log. This is a simple 2-node RAC
cluster. These are simple queries, nothing fancy here. We are picking
records from one table and put "processed" records in a second table and
some "incomplete" records in a 3rd table.
Without going into complete details, has anyone on the list seen
something like that? Any ideas.
Happy Holidays.
Thanks,
-- Pradeep
