-- | PURPOSE  : Oracle writes TRACE to the directory based on the value of your |
-- |            "user_dump_dest" parameter in init.ora file. The trace files    |
-- |            use the "System Process ID" as part of the file name to ensure  |
-- |            a unique file for each user session. The following query helps  |
-- |            the DBA to determine where the TRACE files will be written and  |
-- |            the name of the file it would create for its particular         |
-- |            session.                                                        |
-- | NOTE     : As with any code, ensure to test this script in a development   |
-- |            environment before attempting to run it in production.          |
