  • How to query oracle DB from SQL Server 2008 x64 ?

    Hi Everyone,

    I'm having difficulties in creating a connection from my SQL Server 2008 Enterprise SP2 x64 into the Oracle database 10g even though I have already install the Oracle Client 11g R2 ?

    I've followed this article from steps URL:

    plus added: TNS_ADMIN into the Server variables which point into: C:\Oracle\product\11.2.0\client_1\network\admin

    what is working now:

    TNSNAMES.ORA has been copied successfully from the other Developer wworkstation
    i can TNSPING into the DB instance
    i can connect to the database using SQLplus and perform any SQL commands
    i can create the DSN ONLY when using "C:\Windows\SysWOW64\odbcad32.exe" the normal odbcad32.exe doesn't show my DSN that I have just created ?
    the DSN created from the above works fine from the test connection.

    my goal: To be able to select the Oracle connection in the Linked server object but still no effect after I restart the server. (Windows Server 2008 Enterprise 64 bit SP2).

    Any idea please in resolving this problem would be greatly appreciated.
