It is not possible. Only way to do that would be to create two BI stacks with two different URLs.
I have seen companies do that specially across different departments, for example one stack for Finance, while another for HR. But unless its for security reasons, it should be avoided. This is one of the top costly mistakes while implementing BI. See article below (point #11):
I have create two BI servers and two Presentation servers.
i doing changes in analytics.ear file.
I took the analytics.ear Enterprise Application deployment file, I uncompressed, I changed the ports in the web.xml file for both ananlytics.war and analytics-ws.war I renamed all of them and I created a new analytics2.ear file.
Then I deployed it in the Weblogic Administration Console, bifoundation_domain -> Deployments. Summary of deployments -> Control -> Install.
but when i going to install it show errors.
Could please give me details, how to create multiple BI servers and how to link with respective presentation server.
