Dear all,

I am using RMI program to remote call a C++ exe program. And I need to get back its printf value and return value. Is it possible to get this two values from C++ program to Java program?

Hi,

Did you set TNS_ADMIN environment variable? If not, can you try after setting it?

Thanks,

Senthil:

What should it point to?

Anyway, I re-installed both the 64-bit Oracle DB and the 32-bit client. There are two sets of TNSNames.Ora, Listener.Ora and SQLNet.ora, one for the 64-bit and one for the 32-bit in their respective folders.

I have no problem creating an ODBC DSN for the 64-bit version. The link connects fine to the DB

I have two TNS Listeners defined, one for the 64-bit and one for the 32-bit. While the 64-bit uses Port 1521, I am using Port 1522 for the 32-bit; I also made sure that Listener.ora refers to the same port. But when I use Oracle Net Configuration Assistant to configure Local Net Service Name Configuration to test the Service, it says "TNS:listener does not currently know of the service requested in connect descriptor.

I did check that both the TNS Listener services are running.

I don't know what happened but now, everything works just as expected. I am able to attach Oracle DB tables to an Access database using ODBC. I am able to also connect to the DB using the 64-bit drivers.
