Multiple logback.xml in weblogic server

Question

I am currently using weblogic 12c. As my understanding, weblogic has multiple servers, and each server can run in its own JVM and its own configuration. Moreover, each server can installs and starts more than one application.

Then the question is here, let say

• There is one server instance (Server A)
• 2 applications installed under the server A (App A and App B)
• App A and B have their own logging configuration.
• App A enabled hibernate trace logging
• App B disabled hibernate trace logging
• Once server A started, the trace logging will be enabled OR disabled OR App A enabled but App B disabled? and Why?

Thanks for your time!

I expect App A will be enabled but App B disabled. As each of the app has its own logging configuration althought both of them installed under one server instance.
