Summary
Getting a list of Oracle hints for SQL tuning is often difficult. The Oracle hint list is inside the Oracle executable and you can extract the Oracle hint list easily with UNIX commands. You can use grep and strings to get them directly from the Oracle executable:
strings $ORACLE_HOME/bin/oracle > hints.lst
Here are categorized based on Oracle version. At the end of page there are the Undocumented hints. For more information about hints refer to Metalink Note:221970.1
