Using clob in sql loader utility in oracle 9i

Question

Hi,
I want to load data into a table with 2 clob columns using a sql loader utility dat file and control file created programatically.
The size of clob in dat file can change and the clob columns are inline in data file.
As per 9i doc the size of clob is 4GB .
How can I change the control file so that it can load max 4 GB data in clob columns .
I am getting error while calling sqlldr using below control file :
SQL*Loader-350: Syntax error at line 13.
Expecting non-negative integer, found "-294967296".
,"NARRATIVE" char(4000000000)
^
control file :
LOAD DATA
INFILE '' "str X'3C213E0A'"
APPEND INTO TABLE PSD_TERM
FIELDS TERMINATED BY '~^'
TRAILING NULLCOLS
"PSD_ID" CHAR(16) NULLIF ("PSD_ID"=BLANKS)
,"PSD_SERIAL_NUM" CHAR(4) NULLIF ("PSD_SERIAL_NUM"=BLANKS)
,"PSD_TERM_COD" CHAR(4) NULLIF ("PSD_TERM_COD"=BLANKS)
,"PSD_TERM_SER_NO" CHAR(4) NULLIF ("PSD_TERM_SER_NO"=BLANKS)
,"VERSION_DT" DATE "DD-MON-YYYY HH:MI:SS AM" NULLIF ("VERSION_DT"=BLANKS)
,"LATEST_VERSION" CHAR(1) NULLIF ("LATEST_VERSION"=BLANKS)
,"NARRATIVE" char(4000000000)
,"PARTITION_DT" DATE "DD-MON-YYYY HH:MI:SS AM" NULLIF ("PARTITION_DT"=BLANKS)
,"NARRATIVE_UNEXPANDED" char(4000000000)
)

Yes, you can do it. Create the sequence (suppose you call it "PK_SEQ_X") and then in your control file reference it as "PK_SEQ_X.NEXTVAL". For example suppose you wanted to put it into a column named 'Y' the entry in your control file will look like 'load data insert into table Z (Y "PK_SEQ_X.NEXTVAL", ....)'
Note that the double quotes around the sequence name are required.
