Two apex instances on one machine

Question

I am trying to create two apex instances using the embedded PL/SQL gateway on a single machine. I have two database instances up and running, one for development and one for production. I successfully installed apex 3.2.1 on the development instance, created some simple apps and everything seems to work as advertised, running from port 8080.
I installed 3.2.1 on my other instance and everthing went fine until I had to create a way to connect. My
select dbms_xdb.gethttpport from dual;
returned zero, so I knew I had to set a port to wake up the network services on the instance. That's where I have my question. I cannot find out whether I need to use port 8080 and somehow separate my apex instances based on the DAD or if I should use a separate port for each instance. I tried setting the httpport to 8090 on the new install and my listener shows it active, but when I hit it, I cannot get a response with ~/apex/apex_admin - just a browser password dialog.
The apex environment on the development install continues to work fine, responding to ~:8080/apex/apex_admin.
I am guessing that I have a logical gap somewhere. Where can I read about how to manage this kind of setup?
Thanks,

Brandt:
You want to check if a DAD named 'apex' is configured in the Oracle instance where you have the http port set to 8090.
Login to this instance as the sys user and run this bit of pl/sql. It will display all DADS and their mappings
SET SERVEROUTPUT ON SIZE UNLIMITED
DECLARE
  pths  DBMS_EPG.varchar2_table;
  dads DBMS_EPG.varchar2_table;
BEGIN
  dbms_epg.get_dad_list(dads);
  for i in 1..dads.count loop
    DBMS_EPG.get_all_dad_mappings (
       dad_name => dads(i),
       paths    => pths);
    DBMS_OUTPUT.put_line('Mappings for DAD'|| dads(i));
    FOR j IN 1 .. pths.count LOOP
       DBMS_OUTPUT.put_line(pths(j));
    END LOOP;
end loop;
END;Varad
