Funny ... that Cary mentioned it ....

Some developers here think that by setting some magic instance parameters we can make all RBO tuned code run well under CBO ... (I just bought a 6 pack of Mylanta yesterday ...)

Hamid,

I'm sorry: Unless your SQL returns fewer than about 800,000 rows to the calling application (or an aggregation of 800,000 rows), then the statement "we have done all the necessary tuning on all the SQL queries" is not yet true.

If your SQL does actually return about 800,000 rows, then it is time to begin thinking about the mismatch between business processing requirements and the logical structure of your data.

The answer to your problem is not in your instance parameters.
