Oracle Message PCC-02385 - CHAR_MAP disallowed when using NLS_CHAR and NLS_LOCAL=TRUE

ERRORCHAR_MAP disallowed when using NLS_CHAR and NLS_LOCAL=TRUE
CAUSEThe CHAR_MAP option was specified while indicating which host variables are to be treated by the precompiler as NLS multi-byte character variables. This mapping cannot be performed with the option NLS_LOCAL=TRUE. This error also occurs when DBMS=V6 is used in conjunction with NLS_CHAR and NLS_LOCAL=TRUE.
ACTIONRemove either the CHAR_MAP option or set NLS_LOCAL=FALSE. Ensure that DBMS is not set to V6.
