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 ApplicationBusiness-Level Application is used for managing application artifacts independent of packaging or programming models.

Property Based ConfigurationThe 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

WAS V7.0 Performance Improvement

V7 Web Services performance improvements of up to 100% over the WAS V6.1 Web Services FEP

V7 EJB3 performance improvements of over 30% V7 64-bit memory footprint reduced by 33% and overall

performance improved by 10%. 64-bit memory and performance now equivalent to 32-bit!

• Dominates the overall benchmark category by 33%

• Commanding lead in the throughput per core and single 4-core system categories

• Leading Oracle/HP and Oracle/Sun by more than 16% in performance per CPU core

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.

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.

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
