  © 2010 IBMCorporation WAS V7.0 New Features It is a Java EE 5 compliant application server. Following are the flagship features introduced by WebSphere Application Server Version 7:  Flexible Management Flexible Management facilitates administration of a large number of WebSphere Application Server base edition and Network Deployment topologies that might be geographically distributed.  Business-Level Application Business-Level Application is used for managing application artifacts independent of packaging or programming models.  Property Based Configuration The Property Based Configuration feature simplifies the experience of automating administration: an administrator can update the WebSphere Application Server Version 7 configuration using a simple property file.  Anumber of additional capabilities were made available for V7 in the form of feature packs which are optionally added to a V7 install. Feature Pack content has the same quality and support as main release content - the purpose of a feature pack is to deliver new innovation before the next major release. The following feature packs were provided for WebSphere Application Server V7: – Feature Pack for Modern Batch – Feature Pack for OSGi Applications and JPA 2.0 – Feature Pack for SCA – Feature Pack for Web 2.0 and Mobile – Feature Pack for XML – Feature Pack for Communication Enabled Applications

  © 2010 IBMCorporation WAS V8, V8.5 and V8.5.5 New Features  Version 8.0 – It is a Java EE 6 compliant application server and incorporates the capabilities originally delivered as feature packs with WAS V7. This version of WAS is installed using the IBM Installation Manager.  Version 8.5 – It offers the same Java EE 6 and Java SE 6 (by default) as V8.0 and also provides - and can be configured to run on - Java SE 7. The primary new capabilities in V8.5 are the Liberty profile of WebSphere Application Server and the intelligent management features. – The Liberty profile of WebSphere Application Server is included with all the commercial editions of the server, providing a lightweight profile of the server for web, mobile and OSGi applications. It is a functional subset of the full profile of WebSphere Application Server, for both development and production use, with an install size of under 50 MB, a startup time of around 3 seconds and a new XML-based server configuration which can be treated as a development artefact to aid developer productivity. – Intelligent management capability is added in the Network Deployment and z/OS editions. This integrates operational features that were previously available in the separate WebSphere Virtual Enterprise (WVE) offering: application editioning, server health management, dynamic clustering and intelligent routing.  Version 8.5.5 – It includes significant enhancements to the Liberty profile compared to v8.5. The WebSphere Application Server Liberty Core edition leverages the lightweight and dynamic aspects of the Liberty profile.

  © 2010 IBMCorporation7 WAS V8, V8.5, V8.5.5 Performance Improvement  Java 6 – JVM runtime enhancements – JIT optimizations  Application Performance Improvements vs. WAS v7 – DayTrader: Up to 20% – OSGi Applications: Up to 26%  End-to-end performance improvements vs. WAS v7 including – Up to 15% faster product installations – Up to 20% faster server startup time for developers – Up to 69% faster application server creation in a large topology – Up to 31% faster application server cluster creation in a large topology – Up to 22% faster application deployments in a large topology – Up to 11% better vertical scaling on larger multi-core systems – JPA 2.0 optimizations with DynaCache and JPA Level 2 cache Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here. Performance data is based on WebSphere Application Server in a distributed environment

  © 2010 IBMCorporation WAS 8 Performance Improvement • We focused on performance for v8 because of the TCO advantages that high performance drives  WAS V8 is up to 85% higher throughput than WAS V6.x  WAS V8 is up to 20-26% higher throughput than WAS V7 • From a raw throughput for EJB apps (i.e. # of transaction) standpoint, v8 is upto 20% faster than the latest update of v7. WAS v8 also provides 26% better throughput when running OSGi Apps vs. running Spring 3.0 apps on WASv7 (OSGi Apps contains the standardized Spring component model) • Beyond throughput, we also deliver end-to-end performance enhancements like 20% faster startup for developers, 15% faster installs and 69% faster app server creation in a large topology.  Automation of problem determination task via HPEL (High Performance Extensible Logging) – Up to 6x faster than V7
