This is a description of error (, I hope it will help you:

ORA-12705 invalid or unknown NLS parameter value specified

    Cause: There are two possible causes: Either an attempt was made to issue an ALTER SESSION statement with an invalid NLS parameter or value; or the NLS_LANG environment variable contains an invalid language, territory, or character set.

    Action: Check the syntax of the ALTER SESSION command and the NLS parameter, correct the syntax and retry the statement, or specify correct values in the NLS_LANG environment variable. For more information about the syntax of the ALTER SESSION command, see Oracle8i SQL Reference.
