ORA-01460: unimplemented or unreasonable conversion requested

Question

Hi,
i have a problem with a insert statement
we use C# .net
our database server version is
Oracle Database 10g Client
The problem is:
When iam trying to insert records more than 248 it returns the "ORA-01460: unimplemented or unreasonable conversion requested" error. If the number of records are less than 248, then iam able to insert it successfully. Can u please suggest me what to do inorder to overcome with this.
iam using the following query to insert.
PROCEDURE PINSUPD_UNIT
pi_unit_info CLOB,
pi_user_id DPS_USER.USR_ID%TYPE,
po_unit_cur OUT unit_cur
) AS
v_xmlDoc      SYS.XMLTYPE;
v_xmlNode      SYS.XMLTYPE;
v_intXMLNodeCount      NUMBER;
v_UNIT_ID ECON_UNIT.UNIT_ID%TYPE;
v_DESCRIPTION ECON_UNIT.DESCRIPTION% TYPE;
v_NAME ECON_UNIT.NAME%TYPE;
v_UNIT ECON_UNIT.UNIT%TYPE;
v_sysdate DATE;
INVALID_XML EXCEPTION;
BEGIN
v_sysdate := TO_DATE( TO_CHAR(SYSDATE, 'DD/MM/YYYY HH:MI:SS AM'), 'DD/MM/YYYY HH:MI:SS AM');
-- To extract the Data from the XML Input
IF pi_unit_info IS NOT NULL AND pi_unit_info <> ' ' THEN
v_intXMLNodeCount := 1;
v_xmlDoc := SYS.XMLTYPE.CREATEXML(pi_unit_info);
WHILE SYS.XMLTYPE.ExistsNode(v_xmlDoc, '//Unit_Details[' || v_intXMLNodeCount || ']') = 1
LOOP
v_xmlNode := SYS.XMLTYPE.EXTRACT(v_xmlDoc, '//Unit_Details[' || v_intXMLNodeCount || ']');
v_UNIT_ID := 0;
v_UNIT_ID := TO_NUMBER(SYS.XMLTYPE.EXTRACT(v_xmlNode, '//Unit_ID/text()').getStringVal(),'99999999999999999999999999999999999999');
v_DESCRIPTION := '';
v_DESCRIPTION := SYS.XMLTYPE.EXTRACT(v_xmlNode, '//Description/text()').getStringVal();
v_NAME := '';
v_NAME := SYS.XMLTYPE.EXTRACT(v_xmlNode, '//Name/text()').getStringVal();
v_UNIT := '';
v_UNIT := SYS.XMLTYPE.EXTRACT(v_xmlNode, '//Unit/text()').getStringVal();
IF v_UNIT_ID = 0 THEN
--To insert the Unit Details
INSERT INTO
ECON_UNIT
UNIT_ID,
NAME,
UNIT,
DESCRIPTION,
USR_ID,
LAST_UPDATED_DATE
VALUES
SEQ_UNIT.NEXTVAL,
v_NAME,
v_UNIT,
v_DESCRIPTION,
pi_user_id,
v_sysdate
DBMS_OUTPUT.put_line(v_name);
ELSE
--To update the Unit details
UPDATE
ECON_UNIT
SET
NAME = v_NAME,
UNIT = v_UNIT,
DESCRIPTION = v_DESCRIPTION,
USR_ID = pi_user_id,
LAST_UPDATED_DATE = v_sysdate
WHERE
UNIT_ID = v_UNIT_ID;
DBMS_OUTPUT.put_line(v_name);
END IF;
v_intXMLNodeCount := v_intXMLNodeCount + 1;
END LOOP;
OPEN po_unit_cur FOR SELECT * FROM ECON_UNIT;
ELSE
RAISE INVALID_XML;
END IF;
i know it is a known problem, but still iam trying a lot to overcome it.

I believe, PL/SQL has a limitation of 32K characters for a LONG parameter.
