  1. Oracle 9iAS Enterprise Technology Centre Oracle Corporation

  2. Agenda • Introduction • 9iAS architecture & installation options • Web content cache & load balancing • Web/Java applications & J2EE • Management • Application deployment • Security • Additional features

  3. Technology Trends • Internet Is Ubiquitous • Applications Accessed via Internet / Browser • Applications Deployed on Application Servers • Applications Built to Internet Standards • Information/Data stored in Databases

  4. Typical ‘N’-Tier System Architecture

  5. RogueWave Framework IBM Application Server Netscape Web Server Rational Modeling Times Ten Cache Novell Directory Microsoft Database Iona ORBs Borland Java Tool Actuate Reporting Plumtree Portals Cognos Analysis Technology Challenges • Middleware Complexity Growing • Too Many Pieces • Complex support, licensing, architecture, integration etc • Complex to Develop • Too Many Tools • Unreliable When Deployed • Fragile Infrastructure • Expensive to Manage • Software Cost, Management Cost

  6. Oracle’s Vision – Simplify the Complex • Consolidate Data to Database Servers • Lower Cost, Better Information • Consolidate Applications to Application Servers • Lower Cost, More Reliable Applications Run All Your Applications Manage All Your Data Oracle9i App Server Oracle9i Database Server Clients Browser or Mobile Device

  13. Remove Single Points of Failure with Clustering Browser Cluster 1 J2EE Application ‘A’ Session State Shared Data SourcesWebServices Wireless &Mobile Load Balancers (or Web Cache) Apache Web Servers w/ Load Balancing Internet / intranet Users Cluster 2 J2EE Application ‘B’ Session State Shared • Web Caches share cache content. Load balancing via: round-robin, weighted %, or last use. • Apache maps application/ requests to clusters. • Clusters share application session state via IP multicast.

  14. Clustering Provides High Availability Browser Cluster 1 J2EE Application ‘A’ Session State Shared Wireless &Mobile Load Balancers (or Web Caches) Oracle9i RAC Apache Web Servers w/ Load Balancing Internet / intranet Users • Automatic addition of application servers to clusters • Automatic application deployment to clusters • Transparent re-routing around failed instances and session affinity

  15. Oracle9iAS Infrastructure • The Oracle9iAS Infrastructure consists of: • Oracle9iAS Metadata Repository • Oracle Internet Directory • Oracle9iAS Single Sign-On • Oracle Management Server • The database contains a collection of schemas and metadata that enables the deployment of Oracle9iAS components.

  16. Oracle9iAS and Infrastructure • Enables the deployment of Single Sign-On, Oracle Internet Directory, Oracle Management Server, and Oracle9iAS instance clustering. • Multiple installations of Oracle9iAS can share one Oracle9iAS Infrastructure.

  25. Surge Protection • Resilience to DoS attacks • Buffers load on backend servers • Monitors and ensures performance • Forwards on requests when appropriate • Ensures backend servers not swamped and service requests in required timeframe
