What if the majority of work is in ETL tool and very little database throughput is required.
Example: start session, direct path read big table for a few minutes, do 15hrs etl stuff, 99% of which is not using db resources. Maybe direct this to a math group? Received on Fri Dec 22 2006 - 12:11:29 CST
