PCC-02110:

DBMS=V6_CHAR is deprecated. Use CHAR_MAP=VARCHAR2, DBMS=V7 instead
Cause: DBMS=V6_CHAR was specified on the command line but is no longer a supported option. The options CHAR_MAP=VARCHAR2 and DBMS=V7 were used instead.
Action: This is a warning message only. To avoid this warning, specify CHAR_MAP=VARCHAR2 and, if required, DBMS=V7.
