     On Unix versions of Oracle, you can find details about an error
     message like this:
     <computeroutput>
$ <userinput>oerr ora
<replaceable>00001</replaceable></userinput> 00001, 00000,
"unique constraint (%s.%s) violated" // *Cause: An update or insert
statement attempted to insert a duplicate key //         For Trusted
ORACLE configured in DBMS MAC mode, you may see //         this message
if a duplicate entry exists at a different level.  // *Action: Either
remove the unique restriction or do not insert the key
     </computeroutput>
    </para>
