Weblogic configuration & administration

  1. 1. Oracle WebLogic Server Configuration & Administration from ADF and Java EE Development Perspective
  2. 2. Basic Concepts • Domains • Server / Admin Server • Managed Server • Cluster • Node Manager • Machine
  3. 3. WebLogic Topology Diagram
  4. 4. Domain • Logical grouping of WebLogic Instances • Consists of • Server • Cluster
  5. 5. Server • Server is where we : • Deploy Enterprise Applications or Web Applications. • Create JDBC Resources. • Create JMS Resources.
  6. 6. Types of Server • Administration Sever • Managed Server
  7. 7. 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.
  8. 8. What is a Managed Server • Managed Server is an instance of WebLogic Server Managed by an Admin Server. • Managed Servers in a Domain are Independent of each other, in every aspect. • Applications Deployed in a Managed Server do not share any resources, including JDBC and JMS Connections and Connection Factories.
  9. 9. Admin & Managed Server • On Startup, the Managed Server synchronizes the configuration with • Configuration changes are send over to the Managed Server from the Admin Server.
  10. 10. WebLogic Managed Server
  11. 11. WebLogic Topology
  12. 12. Node Manager • Process to Start/Stop Managed Server instance on a Physical Machine. • Connect to Admin Server and starts/stops WebLogic instance based • Independent of Domain
  13. 13. WebLogic Node Manager
  14. 14. Questions ?
  15. 15. WebLogic Cluster
  16. 16. Benefits of WebLogic Cluster • Scalability • • Even distribution of jobs • • Load Balance 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
  17. 17. WebLogic Cluster
  18. 18. WebLogic & Java EE Compatibility
  19. 19. • WebLogic 11g - JEE 5 Certified • WebLogic 12c - JEE 6 Certified • Java EE 6 • JSP 2.1, JSF 2.0 • EJB 3.1, JPA 2.0 • Context and Dependency Injection • Restful Web Services
  20. 20. The End Questions ?
