ORA-12705

Error: ORA-12705: invalid or unknown NLS parameter value specified

Causa: 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.

Acción: Check the syntax of the ALTER SESSION statement 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 statement, see the Oracle9i SQL Reference.
