deploy a WAR with plan.xml using WLST

Question

I am deploying a WAR file to Weblogic 12c with a plan.xml. My environment runs on three different host machines:

• admin-server host
• managed-server-1 host
• managed-server-2 host

The deployment is done and Weblogic shows on the Console the path to the deployment plan file. But this path is only valid on the admin-server host:

/home/oracle/bin/hello-world/plan.xml

For me, it seems that plan.xml is not used by the application.

I deploy the artifact from the admin-server host. Before the deployment, I copy the *.war and plan.xml to the admin-server disk and I use WLST to deploy to the Cluster.

But I am uncertain whether I need to copy the plan.xml file to the managed-server hosts under the same path that Weblogic shows on the console.

Or the Weblogic admin-server will copy the deployment plan file automatically to all managed servers?

How does this work? Do I need to copy manually the XML to the managed server or not?
