Connecting db2 from oracle

Question

hi,
i)what is the cwbcfg program to be executed you have mentioned.
ii) I executed caths.sql
iii) In tnsnames.ora how to specify the dsn that you create for db2 database.
for example if I have created a dsn for db2 naming it kishore_dsn, how do i specify that in tnsnames.ora file.
and by what sid is the iniths_sid.ora to be created. is it the dsn you create for db2 database. for ex. if dsn name is kishore_dsn, should the file be initkishore_dsn.ora, or it should be the name of local oracle database service.
DESIGN.FORESEEINDIA.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = compaq6)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = design)
KISHORE_DSN =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = compaq6)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = KISHORE_DSN)
(HS = OK)
I am getting ora-12154 tns could not resolve service name, while tring to access db2 after creating public links.
I would appreciate if you can send me step by step generic connectivity ,connecting db2 from oracle.

Hi Tak,
Thanks for your response.
My odbc data source name is : kishore_dsn
driver : ibm db2 odbc driver
I am connecting db2 8 on windows from oracle 9i on windows.
MY iniths_sid.ora file is initdesign.ora
initdesign.ora
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
HS_FDS_CONNECT_INFO = KISHORE_DSN
HS_FDS_TRACE_LEVEL = 0
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
I created listener.ora in network/admin

My sqlnet.ora file
# SQLNET.ORA Network Configuration File: c:\disk1\software\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DEFAULT_DOMAIN = foreseeindia.com
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
Before creating these files I had run caths.sql from sys user.
After all the configuration
I logged into database with service name : kishore
user : scott
I created a db link
create database link custard
connect to scott identified by tiger
using 'kishore';
I issued a select * from addr@custard; where addr is in remote db2 database.
I am getting the following error
ERROR at line 1:
ORA-28546: connection initialization failed, probable Net8 admin error
ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=compaq6)(PORT=1521))
)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=design)))
ORA-02063: preceding 2 lines from CUSTARD
I am struck with this for the past 1 week, so kindly help.
If someone can access a tar from metalink and post it also, as currently we donot have the support.
