Odp.NET

Hi,

I didn’t understand yet, do I need oracle provider (odp.NET) installation when I’m using Oradirect.NET?

I tried to run some of your OraDirect.NET samples and I get:
Cannot obtain Oracle client information from registry. Check if Oracle client software installed.

If I need oracle provider installation, can you please tell me what the deployment of the oracle provider involves?

Thanks

Aviad

This message means that you have to install Oracle client on your computer. It is possible to choose minimal installation configuration, without ODP.
You can connect to Oracle server without Oracle client software if you choose Direct mode in the connect dialog in OraDirect .NET samples

Hi everybody!

I got the same error message on VISTA when I try to connect to my Oracle database in direct mode.

The same application connects without any problems from an XP workstation, the error is showed only on Vista.

My connectionstring looks like the following:

"User Id=scott; Password=tiger; Server=MyServer; Unicode=True; Direct=True; Sid=orcl;"

I'd like to use ClickOnce and do not want to install Oracle Client on each workstation. And most of the workstations are running Vista.

Is there a way to fix this issue?

Thanks,
Frigyes

We cannot reproduce this problem with Direct=true connection. Can you provide a callstack where the error occures (including functions inside CoreLab.Oracle.dll). Please specify the version of OraDirect .NET.

The error stack is the following:

The CoreLab.Oracle.dll is v. 4.30.25.0
The CoreLab.Data.dll is v. 4.25.18.0

Trial version, we are in evaluation phase of your product.

Thanks,
Frigyes

ps:
I was wrong. I put some messages in the application and now I see it can open the connection (I can see the session in the databse), but can not fill the dataset.
Sorry!
Anyway, some help from you will be very appreciated. The same code works on XP without any problems.
