• Create JMS Resources.

Types of Server

• Managed Server

What is Admin Server• Only ONE per domain.

• Controls start and stop of other servers in the Domain.

• Manages the creation of JDBC, JMS and other resources.

• Manages the deployment to servers in the domain.

• In development we use Admin Server for Deployment and Testing. This is usually done via the Integrated WebLogic instance installed within JDeveloper.

Benefits of WebLogic Cluster

• Scalability

• Load Balance

• Even distribution of jobs

• Multiple copies of an object that can do a particular job must be available

• High-Availability

• Failover

• When a object processing a job becomes unavailable, a copy of the object elsewhere takes over and finishes the job
