RE: Different data-sources for different applications?
You can modify this in orion-ejb-jar.xml. This file is found in orion/application-deployments/your-app/ejb You can copy this file to /ear/ejb/orion/orion-ejb-jar.xml and modify it there. ( where ear is your development directory and ejb is your Enterprise Java Bean directory). Hope this helps. -Original Message- From: Anders Bengtsson [SMTP:[EMAIL PROTECTED]] Sent: August 16, 2000 10:28 AM To: Orion-Interest Subject: Different data-sources for different applications? Hello, I'm looking for a way to have different data-sources defined for different applications, installed in the same Orion. The parts of my applications that uses data-sources itself can easily be configured to use a different JNDI name for each application. But I haven't found a way to control what data-source Orion uses for CMP beans. They seem to use some constant JNDI name like "jdbc/DefaultEJBDS" to lookup their data-source. The basic problem seems to be that data-sources.xml is a global configuration, for all the applications in the server. Is there some way to come around this problem, like some way to select the datasource for each application? /Anders A n d e r s B e n g t s s o n[EMAIL PROTECTED] http://www.lecando.com

Ideally it would be possible to change the data-source in some deployment config outside of the .ear.

I'm trying to deploy the same application many times on the same Orion, with different databases, to separate our different customers. we're doing exactly that. just keep one ear and put the orion deployment files in a different place (you can specify that in server.xml in the application tag. that way you only have to change the orion deployment files and keep one ear. Aha, now I get it! Thanks! That should make it possible to deploy a new virtual server in a few minutes, including the time to configure the DNS server. Quite impressive!.. yes, but one thing you should not underestimate is the resources orion uses for each application. we have a very similar concept for an online store app (deploy it once per customer). but this can become a problem in terms of memory usage and server startup time (although the latter has improved a lot recently) if the application is large. we really underestimated that. just do some tests (deploy your app n times) look at memory usage and do the math if it this approach scales well enough for your requirements. regards, robert /Anders _ A n d e r s B e n g t s s o n [EMAIL PROTECTED] http://www.lecando.com (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

Hello Anders, I see you've gotten good answers already, just wanted to point that if you want to use different defaults per application rather than per ejb, you can set the default-data-source attribute in the orion-application.xml file.

RE: Different data-sources for different applications?
Perhaps the best way to do this is to deply the same EAR, but just change the WAR over after you've deployed it?

Hi Karl, A further variation on the theme, We would also like to provide an Application Server service where each site has its own data-source [discussed already], shared EJB [coz the logic is the same] but custom JSP [coz each "eshop" has its own look feel]. Comments on how best to configure Orion for this pls? At the moment we are deploying a single EAR configuring the data-source, which means all the "eshops" are sharing the same WAR and all look the same.
