hi all,
I am trying to create a link from oracle 10g to sql serever but not successful
i have created a dsn for sql server on local machine
my new tnsnames.ora looks like this

bst =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = aaa)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = bst)
)
)

ast =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = aaa)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ast)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

msql =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = tcp)(host=abcd)(port=1433))
)
(CONNECT_DATA =
(SID = msql)
)
(HS=OK)
)

and listener.ora looks like this

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = aaa)(PORT = 1433))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)

SID_LIST_LISTENERMSQL =
(SID_LIST =
(SID_DESC =
(SID_NAME = MSQL)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc)
)
)

LISTENERMSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abcd)(PORT = 1433))
)


when i tns ping ast or bst it is working fine
but when i tnsping msql (sql server ) it gives error
TNS-12537: TNS:connection closed
and i cannot even see the service handlers in
listener stauts

please guide me

AFAIK, you can't create database link from oracle db to sql server.

However, you might try with the Oracle heterogeneous service ODBC agent. Here is a walkthrough; perhaps you'll find it useful.
