Hi,
In order to use the Administration Console of Weblogic 7.0, you need to use at least Netscape 4.7 or IE 5.5

Hi,
I'm trying to figure out which driver I should use in a production environment, to configure my connection pool.
Either connecting to Oracle9i via a type-2 or a type-4 driver.
I know in the past OCI drivers were much more performant, but I have heard it is not true anymore.
Any experience to share ?
Thanks,
Val�ry
Hi,
jnt has got something to do with your JNDI initialContext.
Weblogic cannot find back its own jndi tree.
Don't you have another application server that sets some initial context ? Might be your classpath that's wrong.
Check your system properties for initialcontext.

Hi,
Weblogic has its own Web server.
But if you want to use another one as a proxy server, you can. Weblogic has pluggings for that.
Hope it helps,

Reset your jndi name without the 'basic' word...
Basic, isn't it ?

Well, it seems that new Oracle OCI driver solves the problem is we use an Oracle connection pool.
Now, the question is : How to use an Oracle connection pool with BEA Weblogic server, as it is the application server we use ?
Does the J2EE specification authorize the use of a custom datasource (ie, a datasource that refers to a custom connection pool) while the application server already provides its own implementation of connection pooling ?

We are currently not using connection pooling in our applications, but are pushing the use of CMP EJB, and so, the use of connection pooling as well.
The Oracle DBA is reluctant to use such a means because of the consequences of connection pooling if the Oracle database is not aware of the real userid behind a connection.
They would like us to investigate further in finding a solution whereby web technology is combined with keeping the knowledge of the end-user, at Oracle level, for example.
I am aware that using connection pooling is always depriving the Oracle DBA from specific auditing information about the real user logged in the database, but I am trying to find a solution that suits both DBA and the development team.

Is there another way to use CMP without connection pooling ? For example, by using a self made connector as a datasource ?
Thanks in advance,

Hi,
I'm using the Grinder.
It's free, and very flexible.
The advantage over Optimizeit, is that you can test any server with the Grinder, without having to launch it in a special mode.
In order to use Optimize It, you have to modify the startup script of your application server, for example, in order to monitor it.

Hi,
I am trying to deploy on WLS7.0 an .ear that works fine on WLS6.1
I keep getting the following error message :

Hi,
Weblogic 7.0 has some new modules in the security part.
In order to configure LDAP, you should first create a new Realm, then create an Authentication Provider from the Providers item (under your realm). There, you'll find the different LDAP supported.

Hi,
I'm facing a problem when deploying my ear (working fine in wls6.1) to Weblogic 7.0.
The ejb's are deploying correctly, but the war fails.
It seems that the war cannot see the ejb's as Weblogic could not resolve the ejbLink.
If someone can help !
Here is the error :
Module Name: invoice.war, Error: weblogic.j2ee.DeploymentException: Could not setup environment -

[weblogic.deployment.EnvironmentException: Could not resolve ejbLink: ejb/echeancier]

Hi,
You might want to use the 'monitor connections' from the console to check for not closed connections.
Seems that you don't close your connections systematically.
Maybe the way connections are released (or not released) have something to do with the driver you are using.
Normally, an OCI driver should not be slower than a thin, anyway.
