Gateway for informix: Unsupported Informix Server and other errors

Question

I set up the Database Gateway for Informix on WinXP 32 to connect from an Oracel 10gR2 Database to an Informix Database (Infomix Online Dynamic Server V7.31UP1).
The basic connection seems to work (giving a wrong password in the database link results in an appropriate error message), but the test-statement "select * from DUAL@DLTEST" (and any other select) results in the following error message:
>>>>>>>>>>>>>>>>>
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC Informix Wire Protocol driver]Unsupported Informix Server
version.[Oracle][ODBC Informix Wire Protocol driver]Invalid attribute in
connection string: ArraySize.[Oracle][ODBC Informix Wire Protocol
driver]Invalid attribute in connection string: TruncateOversizedColumnValues.
ORA-02063: preceding 2 lines from DLTEST

Answer 1

Hello,
I downloaded the gateway package of Oracle version 11.1.0.6.0, and installed Informix gateway driver. I made the necessary settings, and i have exactly the same problem, as described above.
I receive error message "OracleODBC Informix Wire Protocol driverUnsupported Informix Server version.OracleODBC Informix Wire Protocol driverInvalid attribute in connection string: ArraySize.OracleODBC Informix Wire Protocol driverInvalid attribute in connection string: TruncateOversizedColumnValues." when trying to set up a connection from Oracle to Informix 7.3. I read here, that there is a patch of Informix gateway: fix 6799360, which is unfortunately not available for for download for Windows XP. I cannot search MetaLink for this problem, because I just would like to test this Oracle feature, I did not buy Oracle license.
Does anybody know about this patch? Can anybody help how could I make working this Informix gateway?
Thanks for help, Gyula
