Unisys has released a JVM for its ES7000 family of servers. They claim to have built an "enterprise-class JVM for a Windows environment".

Unisys has long offered Java-support for its ClearPath mainframe line and over half of the ClearPath customer base utilizes Java components on an enterprise level, Lapinsky told internetnews.com. A number of the customer base of the ES7000 servers also run Java-compatible components like BEA Systems WebLogic application server in a Windows environment although Unisys officials declined to quantify the exact percentage. That's probably because until today, Unisys clients working with Java on the ES7000s had to fend for themselves.
They feel that there is a niche there, as they don't expect Sun to be working hard on making their Windows JVM enterprise ready.
"If you were running a Microsoft server, you had to get your own JVM from Sun for Windows. Sun doesn't put any work in scaling it to a large scale Windows environment," explained Rob Wilkinson, senior marketing manager at Unisys.
In contrast, the Unisys JVM is designed for the enterprise characteristics on the following Microsoft operating systems: Windows Server 2003 Datacenter Edition, Windows Server 2003 Enterprise Edition, Windows 2000 Datacenter Server and Windows 2000 Advanced Server. The technology is based on Sun's Java version 1.4 and can scale up to 32-way processing.
In fact, one independent software vendor that served as a test partner registered an increase of simultaneous users from 3,750 to 5,000 and saw response times drop by one-third using the JVM in an ES7000 environment.
But while Unisys's efforts are noble, it still faces an uphill battle.
"Buyers are tending to go toward suppliers who can give them the whole portfolio of products and servers," Haff said. While he does acknowledge that Unisys has a "very good" services organization, the Illuminata explained that price isn't necessarily the focus particularly in the high-end of the computing market.
"Particularly in that scale of system, functionality and track record are more important than cost. For example, Sun gives away app servers on Solaris. A lot of people still buy Websphere or BEA. It's nice to provide that but the experience elsewhere in the industry is that most people still end up with the proven entities," Haff concluded.

- JRockit by Harris Reynods on July 14 2003 16:05 EDT
What about JRockit ? Isn't it a fairly solid JVM for a windows server?
This is totally off-topic and I apologize, but can anyone tell me where can I find third party reviews of JRockit, especially on Linux.
Hi .. you can get a primary measure of JRockit's effectiveness within the Linux environment via the 'older' SPEC benchmark -- SpecJBB2000 :
& you'll no doubt observe a small collection of JRockit performance numbers :
Company System Result JVM # CPU Published Disclosure
Dell Dell PowerEdge 6650 73532 Weblogic JRockit 8.0 4 Jan-2003 HTML Text
Dell PowerEdge 6650 76136 Weblogic JRockit 8.0 4 Jan-2003 HTML Text
Dell PowerEdge 6650 57245 Weblogic JRockit 7.0 4 Oct-2002 HTML Text
& I've not observed a lot of 4 CPU configurations that exceeded the above perf numbers ( esp, if you are looking for Linux + commodity h/w based deployments ).
BEA's primary focus and goal with WebLogic JRockit is to enable the deployment of high-perfoming enterprise Java applications on the Intel platforms... including Windows and Linux, on both IA32 & IA64 systems. We realize that customers don't just make JVM decisions in isolation, but rather in the context of applications that are certified and supported on them. With WebLogic JRockit 8.1, customers not only benefit from the high quality and performance of WebLogic Server 8.1, but also the entire WebLogic Enterprise Platform 8.1.
Stay tuned over the next few weeks for some very compelling benchmarks on the www.spec.org web site that will demonstrate JRockit's continued performance leadership on Intel servers.
Judging by the whitepapers, I think there is much to love about JRockit. Most JVMs suck on Linux, so this could be a great for Linux users. I would like to purchase support for JRockit without purchasing Weblogic.
The question for me is will JRockit support competing App servers such as JBoss , Pramati etc. ? Are there people running JRockit with other App servers? Does BEA have plans for selling support for JRockit , unbundled from Weblogic ?
While BEA does not support other companies' application servers, there are many customers using JRockit under other application servers since JRockit is available as a fully independent standalone JVM. Its up to other vendors selling applicaiton servers to certify and support their own products on JRockit.
However, customers can already purchase a separate support contract from BEA just for JRockit when it's not used under WebLogic Server. Go here for more info - http://commerce.bea.com/products/weblogicjrockit/support_services.jsp.
In this case, with a valid JRockit support contract, regardless of the application being run on JRockit, if customers run into a JRockit-related problem, they will be entitled to the same support benefits as any other BEA customer.
