I've never needed to use it, but in earlier releases it would have been useful. I remember hitting a bug in 10.2 where a hash group by could give wrong results, and we had to hint some statements to prevent the CBO from choosing that access method. A SQL repair would have had that effect without needing to adjust the code.

I have not used yet. It helps to diagnose and fix valid SQL statements that fail with critical errors at runtime. SQL repair advisor performs a diagnostic operation on the statement and may provide a patch to repair the statement. It is available from Enterprise Manager.
