Identify two reasons for defining machines and assigning servers to them in Weblogic Server.
A.
A machine can be the proxy to a cluster.
B.
A machine definition is required to configure the Node Manager.
C.
To reference an instance of WebLogic Server, you must know its machine and port.
D.
Machine is a required organizational unit. A domain contains machines and machines contain
servers.
E.
WebLogic Server uses server machine assignments to help it choose servers in a cluster on
which to replicate session state.
F.
The machine’s Cluster Weight attribute may be used by load balancers to help them determine
how often to send requests to servers assigned to that machine.
Explanation:
B: The Administration Server uses the machine definition in conjunction with the
Node Manager application to start remote WebLogic Server instances.
E: By default, WebLogic Server attempts to create session state replicas on a different machine
than the one that hosts the primary session state. You can further control where secondary states
are placed using replication groups. A replication group is a preferred list of clustered servers to be
used for storing session state replicas.
Using the WebLogic Server Console, you can define unique machine names that will host
individual server instances. These machine names can be associated with new WebLogic Server
instances to identify where the servers reside in your system.
Machine names are generally used to indicate servers that run on the same machine.
