Resources You Can Manage in a WebLogic Server Domain
Configuring and Managing WebLogic Server 1-15
Machines
The administrative concept of a machine represents the physical machine that hosts an
instance of WebLogic Server. WebLogic Server uses machine names to determine the
optimum server in a cluster to which certain tasks, such as HTTP session replication,
are delegated.
Using the system administration tools you can define one or more machines, configure
Node Manger for those machines, and assign servers to the machines. For UNIX
machines, you can configure UID and GID information.
For more information, see Using WebLogic Server Clusters at
http://e-docs.bea.com/wls/docs81b/cluster/setup.html.
Network Channels
Network channels are an optional feature that you can use to configure additional ports
with one or more WebLogic Server instances or clusters. All servers and clusters that
use a network channel inherit the basic port configuration of the channel itself. You
can also customize a channel's port settings on an individual server using channel
fine-tuning. This fine-tuning process creates an additional network resource called a
Network Access Point.

http://e-docs.bea.com/wls/docs81b/adminguide/network.html.
JDBC
Java Database Connectivity (JDBC) allows Java programs to interact with common
DBMSs such as Oracle, Microsoft SQL Server, Sybase, and others.
Using the System Administration tools you can manage and monitor connectivity
between WebLogic Server and your database management system. Connectivity is
usually established through connection pools.
For more information, see JDBC.
