Avoid Poor Performance and Wrong Results in 11.2.0.4

One of the best notes in MOS got refreshed last night for Oracle Database 11.2.0.4. It has not only information about performance bugs but also about the worst and meanest category of issues, wrong query result bugs. Those are the ones I call the "sleeping beauties" as you as a DBA usually won't recognize them. It is recognized at the application level when the result of a report is incorrect or instead of 4 rows just 3 rows get delivered in the output. Therefore you should be highly aware of those and add this note to your bookmarks.

And in case you don't want to move to Oracle 11.2.0.4 but searching for information and known issues in Oracle 11.2.0.3 or Oracle 11.2.0.2 then please find the corresponding documents:
