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

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

Typical ‘ N ’ -Tier System Architecture

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 Rational Modeling Rational Modeling Iona ORBs Iona ORBs RogueWave Framework RogueWave Framework IBM Application Server IBM Application Server Novell Directory Novell Directory Netscape Web Server Netscape Web Server Microsoft Database Microsoft Database Times Ten Cache Times Ten Cache Borland Java Tool Borland Java Tool Actuate Reporting Actuate Reporting Plumtree Portals Plumtree Portals Cognos Analysis Cognos Analysis

 Consolidate Data to Database Servers – Lower Cost, Better Information  Consolidate Applications to Application Servers – Lower Cost, More Reliable Applications Browser or Mobile Device Clients Run All Your Applications Manage All Your Data Oracle9 i App Server Oracle9 i Database Server Oracle ’ s Vision – Simplify the Complex

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

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

Oracle9 i AS Infrastructure – The Oracle9 i AS Infrastructure consists of:  Oracle9 i AS Metadata Repository  Oracle Internet Directory  Oracle9 i AS Single Sign-On  Oracle Management Server – The database contains a collection of schemas and metadata that enables the deployment of Oracle9 i AS components.

Oracle9 i AS 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.
