Hi Naeem,
You have said the install setup is -
ORACLE_HOME = D:\Oracle\Product\11.2.0\dbhome
GATEWAY_HOME = D:\Oracle\Product\11.2.0\tg
but in the listener.ora you have set ORACLE_HOME for the gateway as -
(ORACLE_HOME = D:\Oracle\Product\11.2.0\dbhome)
To use DG4ODBC installed in the 'tg' ORACLE_HOME then you should configure a listener in the gateway OH -
D:\Oracle\Product\11.2.0\tg\network\admin
and start this listener. This listener will need to use a different port from the RDBMS listener in the other OH.
Change the gateway tnsnames.ora entry used by the RDBMS to reflect this port change.
One other point - SQL*Server is case sensitive so you may need to create the database link as -
create database link sqlserver connect to "uoracle" identified by "uoracle" using 'sqlserver';
if the user/password are defined in lower case in SQL*Server.
Also, the same for object names depending on the SQL*Server configuration -
select "column_name" from "owner"."table_name"@sqlserver ;
Regards,
Mike
