IBM WAS v6.x provides customers with better scaling so more concurrent users can access an application. This can help reduce administrative and licensing costs for companies and provides better flexibility to quickly bring additional user resources on board.

 

What is new for installers

The biggest improvement to the installation process is that now install one copy of the core files (binary system files and processes) on a machine, then use profiles to define multiple application server runtime environments -- each with its own administrative interfaces -- that share the core files. This improvement provides enhancements for preparing, installing, maintaining, and removing installations, including a decreased disk image footprint.

Another big change is the introduction of separate installation routines for the Application Server product, the Web server, the Web server plug-ins, and the clients so that install only what you need on a particular machine.

At a glance, these are the main new items in installation, migration, coexistence, and interoperability:

The biggest improvement in development is support for the J2EE 1.4 specification, enabling you to take advantage of the latest Java technology, as described in J2EE specification. All editions, including WebSphere Application Server Express, are J2EE 1.4 compliant.

Another big change is the inclusion of several WebSphere programming model extensions in all WebSphere Application Server editions, that were formerly available only in certain editions. As a starting point for learning about the available extensions, see WebSphere programming extensions.

In addition, deploying applications has never been easier -- particularly redeploying updated applications or modules. For what is new with deployment, see New: Application deployment improvements.

For information about several smaller but significant changes in the development and assembly infrastructure, and for various types of WebSphere applications, see What is new for developers.

 

What is new for troubleshooters

The biggest change in troubleshooting support and serviceability is increased ability to automatically detect and recover from problems. Many serviceability improvements are described in the IBM Education Assistant presentation:Serviceability enhancements.

The troubleshooting section has been revamped and expanded to include extensive support information, including the ability to search live, Web-based support resources by using the customized query fields in the "Web search" page.
