DB2 Connection VIA ODBC DSN

Question

Can anyone point me to good 'step-by-step' guide to setting up a HS connection to an AS400 DB2 database using a ODBC connection.
I have an ODBC DSN on set up but I'm not sure how set-up my tsnnames.ora or listener.ora, I've looked at several posts in this thread but I'm still struggling.
I basically need to be able to something like 'select something from sometable@AS400link'
Thanks

Tak,
Thanks once again, I still can't get this to work, here's what I have:
On the DB server itself:
\hs\admin\initFRUIT.ora contrains:
HS_FDS_CONNECT_INFO = SPONGE
HS_FDS_TRACE_LEVEL = 0
\network\admin\listener.ora contains:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <name of the host PC>)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:\oracle\ora81)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = FRUIT)
(ORACLE_HOME = E:\oracle\ora81)
(PROGRAM = hsodbc)
(SID_DESC =
(GLOBAL_DBNAME = <name>)
(ORACLE_HOME = E:\oracle\ora81)
(SID_NAME = <name>)
\network\admin\tnsnames.ora contains:
JELLY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <name of the host PC>))(PORT = 1521))
(CONNECT_DATA = (SID=FRUIT))
(HS=OK)
I created a public database link as follows:
create public database link custard
using 'JELLY'
My ODBC DSN is pointing to an SQL Server
Unfortunately I am still getting the same error??
Thanks for your help.
