Oracle Clientid

[sukesh]

Hi,

I know that this issue has been discussed earlier, but since I am getting this error I will raise it again. I am using dotconnect for Oracle version 6.0.58.0 and am writing the following code

Devart.Data.Oracle.OracleConnection conn = new OracleConnection("User Id=xxxx;Password=yyy;Server=10.x.x.y;Direct=True;Sid=Ora2009;Persist Security Info=True;");
conn.ClientId = "Sukesh";
Devart.Data.Oracle.OracleCommand command = new OracleCommand("SELECT SYS_CONTEXT('USERENV','CLIENT_IDENTIFIER') FROM DUAL", conn);

conn.Open();
var result = command.ExecuteScalar();
conn.Close();

I always get null value in the result. Am I doing something obviously wrong here or is the provider having problems setting the client identifier.

Thanks & Regards,
Sukesh

The OracleConnection.ClientId property works only in the OCI mode (via Oracle Client) at the moment. We will investigate the reason why it doesn't work in the Direct mode and notify you about the results.

In the OCI mode ClientId is initialized at the server side after the execution of the first (any) query at the connection. This is a designed behaviour.

Any updates from your investigation?

Our investigation is in progress. I will post here the results as soon as possible.

We have fixed the bug with the OracleConnection.ClientId property in the Direct mode. I will post here when the new build of dotConnect for Oracle is available for download.

How do I use the client ID?
I would like to somehow add the client ID to the connectionstring in web.config so I don't have to set the clientid every time I use a connection (and how does this work with connection pooling?)

I can insert ClientId into the connectionstring, but I need to be able to pass httpcontext.user.identity.name to the connectionstring. How do I go about that?

my connectionstring looks something like this:
web.config:

how does this work with connection pooling?

All connections in the same pool have the same connection string. Could you please describe the problem you have encountered with the client ID and connection pooling?

For example, you can assign HttpContext.User.Identity.Name to OracleConnection.ClientId in the handler of the Login.LoggedIn event.

I don't have problems, I was just wondering how it works across the pool, if different users draw connections from the same pool.

For example, you can assign HttpContext.User.Identity.Name to OracleConnection.ClientId in the handler of the Login.LoggedIn event.

I was looking for something like that.
Thanks I will test it as soon, and give feedback.

Edit:
Hm now I can't even get the quoting to work.
