Oracle 11g/12c makes further use of SQL tuning sets with the SQL Performance Analyzer, which compares the performance of the statements in a tuning set before and after a database change. The database change can be as major or minor as you like, such as: * (E) Database, operating system, or hardware upgrades. * (A,C) Database, operating system, or hardware configuration changes. * Database initialization parameter changes. * Schema changes, such as adding indexes or materialized views. * Refreshing optimizer statistics. * Creating or changing SQL profiles.
