How to lookup Oracle ORA-600 Internal Errors

The ORA-00600 (ORA-600) error is a generic internal error from Oracle, and you must look-up the numeric arguments to understand the nature of the internal error.

A typical ORA-00600 error does not include descriptive text and might look like this, with various arguments following the message in the Oracle alert log::
ORA-00600 [723][51202][1][51200][ ] [ ]

Oracle MetaLink now provides Note 153788.1(Troubleshoot an ORA-600 or ORA-7445 Error Using the Error Lookup Tool) to allow you to get the description for an ORA-600 error. 
You can type-in the numeric argument for the ORA-600 message and get the a MetaLink note relating to the error.

Remember, all ORA-600 errors in the alert log should be reported to Oracle Technical Support, and most Oracle DBAs open an iTAR.
