Hi
I need to implement fine grain control in my database keeping connection pooling on. For that i declared the application context globally. then i created required policy and procedures to implement it. The code of the procedure is given below.

CREATE OR REPLACE package body my_pkg

as

g_session_id number;

procedure set_session_id(p_session_id in number)

is

begin

g_session_id := p_session_id;

dbms_session.set_identifier( p_session_id );

end;



procedure set_ctx(user_name_in in varchar2)

is

branch_id NUMBER;

begin

select branch_id into branch_id from users where user_name=user_name_in;

dbms_session.set_context( 'App_Ctx','mybranch',branch_id,USER,g_session_id);

--dbms_session.set_context( 'App_Ctx','mybranch',branch_id);

--dbms_output.put_line('g_session_id-->'||g_session_id);

--dbms_output.put_line('branch id-->'||branch_id);

end;



procedure close_session( p_session_id in number )

is

begin

dbms_session.set_identifier( p_session_id );

dbms_session.clear_identifier;

end;

end;


If i do not set the identifier (which i need to do in case of global access and connection pooling) and set the context only then the VPD is working fine. But when i try to set the identifier against a user keeping the context global, the process fails. Can any one help?
