Each packaged WAS Liberty profile server is a standalone server. Environmental attributes are most typically isolated in the bootstrap.properties file that is packaged with the server. Starting with the WAS V8.5 Beta there are 2 mechanisms for distributing a packaged server:
1) unmanaged: i.e move the zip and unzip it wherever you wish outside of any WebSphere management infrastructure
2) centrally managed through the WAS ND Job Manager.
