EXP-00104: datatype (BINARY_FLOAT) of column GP in table XXXX.ADAA_DATA is not supported, table will not be exported
so I try to use new feature of 10g expdp,but another errors goes up again
I get on command line:

ORA-39062: error creating master process DM00
ORA-39107: Master process DM00 violated startup protocol. Master error:
