Oracle Database Discussions

I have the following procedure
******************************************
create or replace package app_security_context_ipay AS

procedure set_region_ccode(i_regionccode IN varchar2);

END;

/



-- Create package Body which has access to set the context variables



CREATE OR REPLACE PACKAGE BODY APP_SECURITY_CONTEXT_IPAY AS

PROCEDURE SET_REGION_CCODE (i_regionccode IN varchar2)

IS

BEGIN

DBMS_SESSION.SET_CONTEXT('app_context_ipay','region_ccode',i_regionccode);



END;

END;

/
******************************************************

I have to Pass a long string in it that is
exec app_security_context_ipay.set_Region_ccode
('(130,''375988''),(130,''s1a''),(130,''S1E''),(130,''S1F''),(130,''S1H''),(130,''s25''),(130,''sb8''),(130,''SB9''),130,''SBB''),(130,''SBT''),(130,''SBU''),(130,''SBV''),
(130,''scn''),(130,''SCV''),(130,''seg''),(130,''sfa''),(130,''SNB''),(130,''SNC''),(130,''SPE''),(130,''SRL''),(130,''SS''),(130,''stt''),(130,''SVA''),(130,''SWK''),(130,''SWM''),130,''SXB''),130,''SXC''),130,''SXD''),130,''SXE''),130,''SXX''),130,''SY8''),130,''SZ''),(130,''SZ4''),(130,''SZ5''),(130,''SZD''),(130,''szs'')');

BUT when I pass the string it is truncating after 255 characters.

How can I pass the string to set my predicate to function properly

The Following error I got from the dump file
