Risk of RULE mode in 10g+
746649Mar 15 2010 — edited Mar 15 2010We are upgrading an application to the current version and also upgrading the DB version from 9i to 10g. The application code has several bits of code that are explicitly setting RULE mode. One in a configuration table that can be updated. Second, in several hints in SQL statements that cannot be updated.
I have provided Oracle documentation to the application vendor showing that RULE mode is desupported in 10g+ versions. They were skeptical to say the least.
I had thought that I'd seen stronger warnings that RULE mode could actually generate incorrect result sets when running queries. I have searched but could not find those warnings now. I am trying to make a case to request the application vendor to go back and modify the code before we update to the current version of the application on Oracle 10.2.0.4 version. I'm concerned about the integrity of the result sets.
I am wondering if anyone knows of or can provide a link to the warning that result sets may be incorrect in 10g+ using RULE mode.
Thanks,
Jeff
