What is the format of the external file? Is there only 1 column? How do you determine where a record ends?

This works for me using 10gR2.
Here is my q.txt:
drop table tab1 purge;
create table TAB1
(col1 CLOB
)
ORGANIZATION EXTERNAL
(TYPE ORACLE_LOADER
DEFAULT DIRECTORY MYDIR
ACCESS PARAMETERS
(RECORDS DELIMITED BY NEWLINE
FIELDS (
col1 CHAR(6000)
)
)
LOCATION ('q.txt')
);
select dbms_lob.getlength(col1) from tab1;

I was trying to use clob but I can't find the right syntax
create table xml
( xmlid number (10,0),
xmlname varchar2 (10 char),
xmltext clob,
creation_date timestamp (6),
)
)
organization external
(
type ORACLE_LOADER
default directory xml_data access parameters
(
records delimited by "XML-EOR"
badfile BAD_FILES:'xml%a_%p.bad'
logfile ACCT_LOGS:'xml%a_%p.log'
fields terminated by "XML-EOC" optionally enclosed by '"' LRTRIM
MISSING FIELD VALUES ARE NULL
reject rows with all null fields
(xmlid ,
xmlname ,
select TO_LOB(xmltext) from LONG_TAB ,
creation_date char(26) date_format timestamp mask "yyyy-mm-dd hh24:mi:ss.ff6"
)
)
location
(
'xml.txt'
)
)REJECT LIMIT UNLIMITED
/
I don't know what TO_LOB is or LONG_TAB I found it on some forum and i'm not sure how to use it.

I looked at the bad file and copied a couple of the rejected records and there were over 6,000 characters in that column

I thought I was answering this question
What is the maximum length for the data?
But now that I read it again. It is not clear. Are you asking for the datatype length or the number of characters that can exist in the flat file?

This one. More specifically, the maximum number of characters for the specific field in question.
A CLOB can accept 4 Gig but I cannot use CHAR(4194304000) in my test case (at least in my 10.2.0.3 test database, it core dumps).

OK, I can use 1 byte less than 2 Gig though!

col1 CHAR(2147483647)

I'm running on a 32Bit machine so that may have something to do with it.
