Question : Weblogic managed server being run from different domain directory

I was inspecting a weblogic server which has an admin and a managed server and the managed server seems to be running from a different domain directory i.e. admin sever is in user_projects/domains/admindomain and managed server is in user_projects/domains/managedserver how is it possible?

Answer : Weblogic managed server being run from different domain directory

A directory itself does not constitute a domain.  Look at the invocation script that starts your managed server, to what admin t3 URL is it connecting to?

Something akin to the following:

weblogic.Admin -url t3://some_ip:some_port

I'm guessing they all point to the same admin server to get their domain configuration.
