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

Clustering Provides High Availability Browser Wireless & Mobile Cluster 1 J 2 EE Application ‘A’ Session State Shared Load Balancers (or Web Caches) Apache Web Servers w/ Load Balancing Oracle 9 i RAC Internet / intranet Users – Automatic addition of application servers to clusters – Automatic application deployment to clusters – Transparent re-routing around failed instances and session affinity

Oracle 9 i. AS Infrastructure – – The Oracle 9 i. AS Infrastructure consists of: Ÿ Oracle 9 i. AS Metadata Repository Ÿ Oracle Internet Directory Ÿ Oracle 9 i. AS Single Sign-On Ÿ Oracle Management Server The database contains a collection of schemas and metadata that enables the deployment of Oracle 9 i. AS components.

Oracle 9 i. AS and Infrastructure Ÿ Enables the deployment of Single Sign-On, Oracle Internet Directory, Oracle Management Server, and Oracle 9 i. AS instance clustering.
