DRDA Gateway

I'm connecting from a 9.2.0.2 DB on HP-UX to AS400. Everything works great if everything is under the SAME O_H (O_H/n/a/listener.ora, O_H/n/a/tnsnames.ora, O_H/tg4drda/admin/initdrdaDB2.ora, O_H/bin/g4drsrv) AND my TNS_ADMIN=O_H/network/admin. For this case I used port 1524 (to avoid 1521 being used by my main listener).

However, things don't work when I use my main listener started from a separate O_H. For this case, I copied the (1524) tnsnames.ora and listener.ora pieces into this separate O_H/n/a area (changing the 1524 to 1521 and bouncing the 1521 listener). My TNS_ADMIN=O_H_SEPARATE_LISTENER/n/a. I see the drdaDB2 service from lsnrctl.
>From SQL*Plus:

SQL> select * from dlcdbat.doc_ctl_tbl_at_db2; ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent NCRO: Failed to make RSLV connection
ORA-02063: preceding 2 lines from DB2

Any ideas why things don't work if I utilize a separate O_H for my listener? BTW, this listener O_H does NOT have any gateway S/W installed. Should this matter? The ORACLE_HOME and PROGRAM listener.ora params specify the correct O_H and shell script name in the "gateway" O_H. Where's the rub?
