our app developer group has this query that they run that is the same as the query text on the dba_sql_profiles view. however, it appears to be that the SQL profile is not being used by the optimizer. when i looked further the query that they run is different from the query text on the dba_sql_profiles. the only difference is the hints "/*+ INDEX ... */". the query text on the dba_sql_profiles does not have hints while the query that they are running has a hints.
should the query be exactly the same as the query text on the dba_sql_profile for that to be recognize by the optimizer (text sensitivity such as upper and lower case, white space etc.)?
thanks,
warren

No. The signature has to be the same. If you created your profile with force_match => true then the force matching signature has to be the same. If you created your profile with force_match => false (it is the default) then the exact matching signature has to be the same.
In your case the hint makes the signatures different.
