RE: rm RULE based optimizer != GOOD IDEA

or..."one of our developers used HASH JOIN hints all throughout their SQL, now we had to go back and remove them and this took time and $$$, can't wait until HASH JOIN hint is removed."

you see the problem in this case and the case below has to do with the review process, not the mere existence of the hint

One of our developers used RULE hint widely in our latest project. As a result we had to inspect almost all of them (taking time and $$$) when moving to production. So from now I'm planning to allow RULE then and only then if developer can explain _ALL_ RBO rules :))) (http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96533/rbo .ht=3D

As a result I hope that those who will be able to do that would understand that it is a bad idea.
