Oracle 9.2.0.1.0 transparent sqlserver gateway

Question

Hi!
I have a sqlserver 2000 running. I also have a oracle 9.2 server with
windows 2003 running.
I installed after oracle enterprise edition setup the oracle gateway services for sqlserver on my oracle server and made some changes in the *.ora files.
Then I made some changes in the different oracle ora files.
That was all I have done.
My problem:
in the oracle enterprise console I can add my sqlserver database. But when I
enter my user and password I can not connect to my sqlserver database.
I also started the OracleOraHome92TNSListener new.
what is my problem?
In tg4msql_agt_3352.trc I saw the following error message:
heterogenous agent release
9.2.0.1.0
HS Agent diagnosed error on initial communication, probable cause is an error in network administration.
network error 2: NCR-00002:
here are my files:

Answer 1

you need to create the DATABASE LINK.
Opne SQL*Plus and connect as system user;
then create the database link to the SQL Server like:
create database link mssql connect to "sa" identified by " " using '<the tns alias of the gateway you specified in tnsnames.ora>';
Pay attention; the db link uses a blanc password for the SQL Server user sa. If your user has a password; then add the existing password between the double quotes.
Now to fetch some records, specify the select:
select * from all_catalog@mssql;
