How to Deploy, Monitor and Manage Middle-Tier Applications Lars Ewe, Principal Product Manager Valerie K. Kane, Group Manager Oracle Corporation Session id: 40025

Agenda  Understanding J2EE Applications  J2EE Application Management Lifecycle – Deploy – Monitor – Diagnose – Administer  Q & A

Understanding J2EE Applications

Application Layers Mapped to J2EE Tiers and Technology  J2EE helps developers build layered applications, each providing different services Servlets HTML, JSP Java Objects, Session Beans Java Objects, Entity Beans Control Presentation Business Logic Persistent Objects Web Tier Business Tier Application LayerJ2EE Tier J2EE Technology

Web Application / JDBC  Pros – Simple to build – Simple to package and deploy – Low overhead from container – Relatively easy to test  Cons – Needs discipline to keep UI and logic separate – No container transaction support – Must code all database calls JSP + Servlet UI Business Logic JDBC DB Web Container

Web Application / Local EJB  Pros – Separation of business logic – Entity beans for persistence – No serialization or network calls – Concurrency managed – Can convert to remote interface and Web service endpoint if required  Cons – Uses EJB infrastructure – Harder to test business logic behind local interfaces JSP + Servlet UI Session Bean - Logic Entity Bean - Persistence DB Web + EJB Container local

Web Application / Remote EJB  Pros – Most flexible architecture – Can separate EJB container to different server – Multi client enabled – Can be exposed as Web service endpoint  Cons – Slower performance, remote network calls and serialization – Can be difficult to configure and debug Session Bean - Logic Entity Bean - Persistence DB Web Container remote JSP + Servlet UI EJB Container Web Container

J2EE Platform Roles  Product Provider  Tool Provider  Application Developer  Application Assembler  Application Deployer  System Administrator Focus of this presentation

Application Assembler and Deployer Role  Application Assembler – Packages set of components to build the EAR using a tool or utility – Documents external dependencies for the application  Application Deployer – Configures external dependencies for the application – Deploys the application to application server

Application Deployment  Deployment Steps – Map URLs – Map Resource References – Publish Webservices (if needed)  Application Configuration – Resources – Security

Model End-User Communities Web Application Availability and Performance may vary from location to location

End-User Performance  Monitoring of ALL URLs accessed by ALL users  End-user impact analysis  Server vs network response time  Analysis of end-user response times by URL, domain, regions, visitor, Web server  Web server load and response distribution  Watch list to highlight performance of critical URLs Web Application

Interactive Cross-Tier Transaction Tracing URL/JSPEJBJDBC/SQL  On-demand diagnosis of problems across tiers of J2EE Web application  Intuitive drill-downs of all invocation paths to the SQL level internet Middle Tier

Page Performance Analysis ServletEJB JDBC/SQL  Full URL processing call stack analysis  Tracing down to the SQL statement level  Tuning Recommendations internet JSP Processing time and Load Slowest URLs and # of Hits Top Servlets & JSPs by Requests & Processing Time Application Performance Correlation

D E M O N S T R A T I O N Application Performance Management

J2EE Monitoring  Pre-defined thresholds  Alert notifications and response actions  Blackout periods  Performance baselines  Graphical performance charts  Historical data repository  Performance trends and comparisons

Monitor Application Server Performance at Multiple Levels  Server resource usage  OC4J container performance  J2EE application responsiveness  Servlets, JSPs and EJBs performance

Application Server Historical Data Trends and Comparisons  What’s the current CPU usage for server #1?  How did it do over the past 24 hours?  How does that compare to server #2 over the same timeframe?

J2EE Application Diagnostics  Real-time and historical performance  Easily identify top resource consumers

J2EE Diagnostic Drilldowns  What are my top web modules, servlets & JSPs?

J2EE Diagnostic Drilldowns  What are my top EJBs and EJB methods?
