How to Find the Hostname / IP Address of Reports Server From Forms

Question

Hi
We have following query to find out on which machine form server is running,
but how to find hostname/ip address of reports server (if there are more than one reports server running and on different machines).
SELECT SYS_CONTEXT('USERENV','HOST'), SYS_CONTEXT, SYS_CONTEXT('USERENV','IP_ADDRESS')
from dual.
can anybody answer?

Our oas name is the same as the box name, and the report server naming convention is rep_(oas name) so that makes it easy to find out.
I have a pll attached to my form that contains the following function, which works for PC or UNIX based app server:
-- get_oas_name - Returns OAS name. 
-- caveat:  Can't be run from pre-form, when-new-form-instance or when-new-block-instance of first
--          block on the form due to webutil limitation.
FUNCTION get_oas_name RETURN varchar2 IS
  fp text_io.file_type;
  oas_name varchar2(30);
  op_sys varchar2(30) := get_application_property(OPERATING_SYSTEM);
BEGIN
  if op_sys = 'WIN32COMMON' then                    
    oas_name := webutil_clientinfo.get_host_name;
  elsif op_sys = 'SunOS' or op_sys = 'UNIX' then
    host('/bin/uname -n > /tmp/oas_name');
    fp := text_io.fopen('/tmp/oas_name','r');
    text_io.get_line(fp, oas_name);
    text_io.fclose(fp);
  end if;
  return oas_name;
END;Then in when_timer_expired (first place you can use webutil functionality) call it accordingly. I also use it to set platform dependant variables so the form will run
when I'm working on my PC or deployed on UNIX:
declare
  :control.op_sys  := get_application_property(OPERATING_SYSTEM);
begin
      :control.oas_name := get_oas_name;
      :control.report_server := 'rep_'|| :control.oas_name;
      if :control.op_sys = 'WIN32COMMON' then        -- For running locally during development.                     
        :control.close_page := 'http://127.0.0.1:8889/forms90/common/window_close.htm';
        :control.rpt_temp := 'c:\temp\';
      elsif :control.op_sys = 'SunOS' or :control.op_sys = 'UNIX' then
        :control.close_page := 'http://'||:control.oas_name||'.yournamehere.com:7779/forms90/common/window_close.htm';
        :control.rpt_temp := '/appl/oas/yournamehere/reports/cache/';
      end if;
end;Good luck,
