Forms (version?) has an older engine, so I guess you have to create a server-side function returning the sys_context parameter value. Call that from your Form.

You can try someotherway round.

Just make one backend function returning varchar2.

CREATE FUNCTION FUNC_GET_IP
RETURN VARCHAR2 IS
V_IP VARCHAR2(50);
BEGIN

SELECT SYS_CONTEXT('USERENV','IP_ADDRESS')
INTO V_IP
FROM DUAL;

RETURN V_IP;

END;

And now in your Form use this to fetch the Value.

p.s: There could be lot others ways to do it. I thought of this as simplest

Yep, that's what I said:

Like I stated

so I guess you have to create a server-side function returning the sys_context parameter value. Call that from your Form.

BTW: I'd do it like this (slightly improved:no fetch,no needles variables):

SQL> CREATE OR REPLACE FUNCTION f_sys_context(p_env_param IN VARCHAR2)
  2  RETURN VARCHAR2
  3  IS
  4  BEGIN
  5    RETURN SYS_CONTEXT('USERENV',p_env_param);
  6  END;
  7  /

Nah!
