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.
