Hello,

I can make connections to my Oracle 11.1.6 Database (in direct mode) from XP sp3 32bit and
W7sp1 32bit with the following connectionstring:
connectionString = "User Id=user;Password=passwd;Direct=true;Data Source=192.168.123.25;Sid=DEV;Port=1522;";

However, this connection doesn't work with W7 sp1 64bit ultimate.

Development platform is XP prof SP3 32 bit.
I generated the code in x86 mode.

Do you have any idea?
Thank you,

Extra info:
I tested today on above platform with JDeveloper+JDK7 (32bit and 64bit) in direct mode and both tests were successful.
regards.

Hello,
just an idea but can it be that the windows firewall on the W7 64bit is blocking the connection?

We've had that problem. Deactivating the firewall (or allow the connections) was our solution.

Kind regards
Peter

Devart DLLs are MSIL binaries and cannot be resolved by x86 programs in 64-bit environments. You should consider compiling as Any-CPU if running in 64-bit Windows is desired.

Peter,

I tested with the firewall off with no result. I tested also with JDeveloper/Java in 32bit and 64bit versions which were both successful.
thx anyway.

GrMikeD,
Can I compile with Any-CPU on a XP prof 32bit SP3, or do I have to move VS and DotConnect first to a W7 64bit platform?

Regards.

Sure, just change active platform using Build->Configuration Manager menu in VS. Glad to help.

GrMikeD,


First build VS and Dotconnect on W7 64bit platform and it work for the testapp. Than I checked again with the XP platform and I did what you proposed. And it worked too. Thx for all.

Regards.
