Oerr is an Oracle utility that extracts error messages with suggested actions from the standard Oracle message files. This utility is very useful as it can extract OS-specific errors that are not in the generic Error Messages and Codes Manual.
 oerr for Unix
$ oerr ora 600 ora-00600: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s] *Cause: This is the generic internal error number for Oracle program exceptions. This indicates that a process has encountered an exceptional condition. *Action: Report as a bug - the first argument is the internal error number
 oerr for Windows
Oracle doesn't ship an "oerr" utility for Windows platforms. However, a perl script is available to simulate oerr behavior on Windows.
