Problem with "Database Gateway for SQL Server"

Question

Hello,
i am testing the different technologies for connecting an oracle database with a sql-server database.
The way using 10g-generic-connectivity with ODBC works fine, but the 11g-DG4MSQL makes problems.
Environment:
Server PEGASUS (32bit Windows Server 2003 R2 SP2) with Oracle Database 10g Release 10.2.0.4.0
Server OBELIXUS (32bit Windows 2000 Sp4) with MS-SQL-Server 2005
On PEGASUS i have installed the gateway in a new oracle home directory:
"D:\oracle\product\10.2.0\db_1" => home directory of 10g
"D:\oracle\product\11.1.0\tg_1\" => home directory of the gateway
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora:
MSSQLDG =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = DG4MSQL)
(HS = OK)
MSSQL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1521))
(CONNECT_DATA =

(HS = OK)

(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

How mentioned above, the access from oracle to sqlserver using MSSQL(10g hsodbc.exe) works fine.
But when trying to acces the sqlserver using MSSQLDG (11g dg4msql.exe) I get the following error:
ORA-28500: Verbindung von ORACLE zu Fremdsystem gab diese Nachricht zurück:
[Oracle][ODBC SQL Server Driver][DBNETLIB]Ungültige Verbindung.

Answer 1

At first your configuration is not really correct.
=====================================================
In the LISTENER.ORA from 10g, you must only refer to the database and hsodbc 10g
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = INTEGRAT)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = INTEGRAT)
(SID_DESC =
(SID_NAME = MSSQLTEST)
(PROGRAM = D:\oracle\product\10.2.0\db_1\bin\hsodbc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1521))
===========================================================
Then you have to create a new listener (new name) in the gateway oracle_home on a different port than instance database:
D:\oracle\product\11.1.0\tg_1\network\admin\listener.ora
SID_LIST_LISTENERGTW =
(SID_LIST =
(SID_DESC=
(SID_NAME=DG4MSQL)
(ORACLE_HOME=D:\oracle\product\11.1.0\tg_1)
(PROGRAM=D:\oracle\product\11.1.0\tg_1\BIN\dg4msql)
LISTENERGTW=
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1522))
To start it, use the command below:
D:\oracle\product\11.1.0\tg_1\bin\LSNRCTL start listenergtw
===========================================================
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora:
match the DG4MSQL with the listener on 1522 port
HSODBC match with binary10g on listener 1521 port
MSSQLDG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1522))
(CONNECT_DATA =(SERVICE_NAME = DG4MSQL))
(HS = OK)
MSSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1521))
(CONNECT_DATA =(SERVICE_NAME = MSSQLTEST))
(HS = OK)
Try to configure and let me know your feedback
