This tutorial shows you how to use the WebLogic Scripting Tool (WLST) to administer Oracle WebLogic Server 12c (12.1.3) from the command line.
A WebLogic Server cluster consists of multiple managed servers running simultaneously, running the same applications, and working together to provide increased scalability and reliability. A cluster appears to a client as one WebLogic Server instance. Web application client requests go to the cluster proxy, which passes those requests to one of the servers in the cluster. A cluster proxy can be a web server, a hardware load balancer, or even another instance of WebLogic Server itself. The managed servers that make up a cluster can run on the same machine or on different machines. For increased reliability, managed servers in a cluster typically run on more than one machine.
This tutorial shows you how to use the Oracle WebLogic Server 12c (12.1.3) administration console to create a basic cluster and add servers to it. Additional tutorials extend this cluster's capabilities to support load balancing and failover of Java Platform, Enterprise Edition applications
