Linking to SQL Server using DG4ODBC

Question

Hi all,
I've configured Oracle 11g R1 for Windows 2003 Server 32-bit to connect to MS SQL Server 2005 through ODBC.
Following is the error I got when I try to access SQL Server by the db link in Oracle:
SQL> select sysdate from dual@sqls ;
select sysdate from dual@sqls
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from SQLSThe ODBC link to the SQL Server was successfully tested.
The listener, however, returned error as shown below.

Answer 1

You did create a DUAL table in the Sqlserver database?
