What's New in WebSphere Portal V5.1.0.1?

IBM's domination of the portal market continues

Digg This!

The first thing that you said to yourself when you saw the title of this article is, “Why am I reading an article about a point release? A fixpack update point release usually provides just technical fixes. Who cares?”

Surprise! WebSphere Portal 5.1.0.1 provides a lot of new and updated capabilities originally intended for the WebSphere Portal 5.1 release, as well as the typical set of tweaks and fixes to some product components.

It’s a full release (it’s not really a full release…) with new functionality, platform support, and, yes, bug fixes. It contains some long-anticipated enhancements that didn’t quite make it into WebSphere 5.1 (but were supposed to).

New Platforms
Yes, we finally did it! We finally have support for all of our WebSphere Portal platforms on the same release with the same functionality support (well almost…).

WebSphere Portal V5.1 for z/OS
For mainframe fans who’ve felt a bit abandoned, we’re now able to align the technical application and portal component support needed, and – we’ve heard your complaints – and have released a fully functional robust version of WebSphere Portal Version V5.1 for z/OS 1.4.

With Portal 5.1 we bring our Portal z/OS support up to functional parity with the multi-platform Portal with close to 100% code compatibility.

We’ve also simplified the install and configuration by adopting the multi-platform install technique of starting with a Cloudscape-based configuration and letting it be configured to one’s specific needs.

The biggest difference between the multi-platform portal and the z/OS portal is that the z/OS portal exploits many of the z/OS qualities of service including:

Native exploitation of the z/OS hardware
z/OS exploitation of native WLM controls and algorithms
Parallel Sysplex support for superior scaling and growth
Multiple JVM support through multiple WebSphere Servant region support
Application isolation through WebSphere split Controller/ Servant design
Use of DB2 for z/OS 7.1 Sysplex data sharing
Use of Sysplex Distributor and Dynamic VIPA for transaction failover and rerouting
Exploitation of FFDC technologies

In terms of performance, we’ve engineered Portal for z/OS to perform equal to or better than the WebSphere Portal 5.1 for Multi-platforms release due to the platform performance capabilities – multi-platform in the areas of measured, end-to-end response time from the browser to the server and back with near linear CPU scaling of up to 64 processors, as well as support for a greater number of connected and active users.
