    Error on connecting from Oracle to SQL Server with generic connectivity

    Hello,

    I am trying to setup a connection using Heterogeneous Services between Oracle 10g R2 on Linux RH4 and SQL Server running on Windows 2k.

    I have configured an ODBC driver (unixodbc from www.unixodbc.org) to connect to the windows database, and everything is going ok from the command line, using the odbc utility 'isql':
    $ /usr/local/unixodbc/bin/isql MSSQLTestServer user pass
    +---------------------------------------+
    | Connected! |
    | |
    | sql-statement |
    | help [tablename] |
    | quit |
    | |
    +---------------------------------------+
    SQL>select count(*) from tab;
    15
    SQL>

    MSSQLTestServer is the odbc data source that i've set in odbc.ini file.

    After i have made the configurations in Oracle (the listener.ora, tnsnames.ora, initHSDWNCUBE1.ora files) and created the database link, when i try to execute a select, i get the following error:

    select * from tab@hslink;

    ERROR at line 1:
    ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
    [Generic Connectivity Using ODBC]DRV_InitTdp: DB_ODBC_INTERFACE (2082): ;
    [unixODBC][FreeTDS][SQL Server]Unable to connect to data source (SQL State:
    S1000; SQL Code: 0)
    ORA-02063: preceding 2 lines from HSLINK

    So you can see the whole picture, i will also give the configuration of the files:

    LISTENER.ORA
    -----------------
    TEST =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = tcp)(HOST = 10.0.1.80)(PORT = 1522))
    (ADDRESS = (PROTOCOL = ipc)(KEY = EXTPROC))
    )

    SID_LIST_TEST =
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = /app10g)
    (PROGRAM = extproc)
    )
    (SID_DESC =
    (GLOBAL_DBNAME = test)
    (ORACLE_HOME = /app10g)
    (SID_NAME = test)
    )
    (SID_DESC=
    (SID_NAME=hsdwncube1)
    (ORACLE_HOME=/app10g)
    (PROGRAM=hsodbc)
    (ENVS=LD_LIBRARY_PATH = $LD_LIBRARY_PATH:/usr/local/unixodbc/lib:/usr/local/lib:/usr/local/freetds/lib)
    )
    )


    TNSNAMES.ORA
    -----------------
    hsdwncube1id =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = tcp)(HOST = 10.0.1.80)(PORT = 1522))
    (CONNECT_DATA =
    (SID = hsdwncube1)
    )
    (HS = OK)
    )


    $ORACLE_HOME/hs/admin/inithsdwncube1.ora
    -------------------------------------------

    HS_FDS_CONNECT_INFO = MSSQLTestServer
    HS_FDS_TRACE_LEVEL = 4
    HS_FDS_TRACE_FILE_NAME = /tmp/hsodbcsql.trc
    HS_FDS_SHAREABLE_NAME = /usr/local/unixodbc/lib/libodbc.so

    set ODBCINI=/usr/local/unixodbc/etc/odbc.ini

    I have tried everything, and i don't know what's wrong with my configuration, i didn't find any clues on forums/metalink.
    Please help!!!!

    Thank you in advance,
    Georgia

    Why don't you create ODBC as hsdwncube1 and change

    HS_FDS_CONNECT_INFO = MSSQLTestServer

    to

    HS_FDS_CONNECT_INFO = hsdwncube1

    Hello,

    I have tried what you suggest and it doesn't work, i get the same error.
    The MSSQLTestServer was the data source name that i have defined in the odbc.ini file, so it should work.

    Thanks for your suggestion.
    Any other ideas?

    Thanks,
    Georgia
