Hi all~ We are in the process of upgrading our database from 9i to 11gR2 on Solaris SPARC 64-bit platform. I was wondering if anyone knows a list of oracle hints that will not work anymore in 11gR2 and that used to work in 9i. I know that there are whole lot of new hints introduced in 11gR2, but I could not find a list of obsolete/deprecated hints from 9i to 11gR2. Any pointers is appreciated. Thanks Bheem Aitha
