List, I'm planning an upgrade from 10.2.0.4 to 11gR2. I'm concerned that some SQL plans will not behave as they currently do. This is a critical OLTP system supporting manufacturing. Easily crippled by a bad query. 11g has a method to move SQL plans from 10g to 11g. Has anyone used this? Dennis Williams -- //www.freelists.org/webpage/oracle-l
