Presentation abstract: Many will know Cardinality Feedback as a SQL tuning method from Wolfgang Breitlings famous paper Tuning by Cardinality Feedback. In 11g Oracle automates this method to correct cardinality estimates by learning real cardinalities from earlier executions. In this presentation we look at how this feature works - and when it doesn't - and put it into context with other tuning strategies.
