Magic Quadrant for Application Platform Suite (APS) – 2004 “Green In Regulation”


“Oracle was one of the first vendors to offer an extended APS package…During the past few years, Oracle has lavished massive resources on it’s APS initiative. Oracle’s APS is rich in functionality, some of which is also available as add-ons for other vendor’s APSs.

Although less visible than other competing products, the Oracle platform has been adopted by a large and growing number of users, shows good industry support, and is the revenue leader in the stand-alone APS market.”

Oracle Web Cache & Java Object

Cache


Golf Tip #7Never Quit the Game


How Web Cache Works

1. Client sends HTTP request2. Web Cache responds immediately if cached object is available 3. If object is not in cache, Web Cache requests object from Application Server4. Application Server generates response (may include Database queries)5. Application Server responds to Web Cache6. If response is cacheable, Web Cache retains a copy for subsequent requests7. Web Cache responds to Client8. Cached object either expires according to configured policy or…9. Object is programmatically or manually “invalidated”

Key Features• Whole-page Static and Dynamic Caching

• Partial-page Caching and Personalized Content Assembly (ESI)

• Invalidation and Performance Assurance Heuristics

• Automatic Content Compression

• Web Server Load Balancing and Failover

• Cache Clustering

• Remote Office Deployments (eCDN)

• Real End-user Performance Monitoring

• Integrated with Oracle Tech Stack: 9iAS, 9iDB, 9iDS, 11i Apps, OEM

• Compatible with 3rd-party Application Servers and Databases


Java Object Cache

The Java Object Cache is an “in-process” cache of Java objects that can be used on any Java platform and by any Java application. It allows applications to share objects across requests , across users and coordinates the life cycle of the objects across processes.

High Availability


High Availability in AS10g


Infrastructure Cold Failover Clusters

For customers with 95% or higher uptime requirement

Industry Standard Solution (using hardware clusters)

Vendor certified: Sun, HP, IBM, Red Hat, Veritas, Fujitsu-Siemens, etc.

Failsafe for Windows


Infrastructure on Active Clusters Best of Breed For customers who

need 99.99% uptime Failover is seamless Uses Oracle’s RAC

technology Because it is an

Active/Active configuration, it also provides high scalability

– weighted, local affinity, metrics-based, round robin, random

OPMN provides death detection and restart for all processes

– Self Healing

Support for File based repository for OC4J clusters


Middle Tier High Availability

Hot Deployment– Supported in oc4j standalone– Supported for “well behaved” applications (stateless

applications) in Oracle Application Server

Achieve High Availability with “loosely coupled clusters” (multiple installations front-ended by a load balancer or web cache):

– Portal, Reports, Forms, Discoverer, Wireless– The oc4j engine for these apps do not store state, so

clustering and session state replication are not needed
