Computing good real-valued prediction coefficients isn't that difficult, actually. But these coefficients also need to be coded somehow which involves quantization. One option is to simply quantize the optimal real-valued coefficients to rational numbers that share a certain denominator. FLAC's format specification for example allows transmission of rational coefficients that have a power-of-two as denominator. However, simple per-coefficient rounding to the closest rational number doesn't necessarily lead to the best set of quantized coefficients. What does "best" mean anyway? Suppose we fix the prediction order and the prediction coefficients' accuracy (denominator). We'd like to choose a set of quantized prediction coefficients that reduce the number of bits spent on the residual samples. Since this is a really complicated minimization problem we need to simplify our objective function. The natural choice is to minimize the sum of squared (not-yet-quantized) prediction errors instead. This objective function turns the problem into an "integer least squares" problem.

Suppose you have a block of $latex m$ samples $latex s_k$ ($latex 1<=k<=m$), you want to compute $latex n$ prediction coefficients ($latex n << m$) for the remaining m-n predictions (the first n samples are the "warm-up" samples) and the coefficients' denominator is 'p' for "precision". This leads to the following integer least squares problem ILS(A,b):

$latex A = (a_{i,j}) \in \mathbb{R}^{m-n,n} \, , \, \, b \in \mathbb{R}^{m-n}$

$latex a_{i,j} = s_{i+j-1} \, , \, \, b_i = p \cdot s_{i+n}$

for $latex 1 <= i <= m-n$ and $latex 1 <= j <= n$

find $latex x \in \mathbb{Z}^n$ that minimizes $latex || A \cdot x - b ||$

ILS (integer least squares) is known to be NP-hard which practically means that computing the optimal solution for a large problem (matrix with many columns) takes quite some time. However, in case of typical linear prediction problems the complexity of computing the optimal set of oefficients is rather moderate.

How do we solve an ILS problem? There are a couple of approaches. Many include a popular tool known as LLL lattice reduction. With the help of orthogonal transforms and the LLL lattice reduction algorithm the above problem can be reduced to another instance ILS(R,y) where R is square upper triangular matrix of order 'n' with a near-orthogonal columns of low norm. A by-product of the reduction process is a an integer matrix M which connects the two problem instances: Assuming w is an optimal solution for ILS(R,y), x=M*w will be an optimal solution for ILS(A,b). Since M contains integers only, x will also be an integer vector. This reduction process is a kind of preconditioning which means the problem ILS(R,y) is "easier" to solve than ILS(A,b).

Still, we need to solve ILS(R,y). A simple approximation of the optimal solution is called Nulling and Cancelling:

$latex w'_j = \lceil \frac{y_j - \sum_{t=j+1}^{n} R_{j,t} w'_t}{R_{j,j}} \rfloor\,$ for j=n,n-1,...,1

The approximation's coefficients are computed one at a time. Except for the rounding part ($latex \lceil \cdot \rfloor$ denotes the closest integer) this is exactly what you do to solve a triangular system. Note that previously quantized coefficients are reused to solve for the next coefficient. If we're lucky we already found the optimal solution (w'=w). But there's no easy way to tell. The optimal solution can be computed with an informed tree search where each outgoing edge corresponds to a certain quantization decision. At the first level $latex w'_n$ is quantized. Next in line is $latex w'_{n-1}$ until we reach a leaf node where all coefficients have been determined. Coupling a depth-first search with branch and bound that picks the most promising path first is what I did for my C implementation.

East Midlnads based Monumental Games have won £300,000 of funding from the Technology Strategy Board, they announced yesterday.

It makes a lot of sense, as networked technology is looking like one of the safest bets in games at the moment.

I do wonder if Rocco wrote this or it was written for him, as press release quotes often are:

Project Chairman Rocco Loscalzo (CTO of Monumental) praised the approach of the Technology Strategy Board. “This is the first year that the Technology Strategy Board has invited applications from the Creative Industries, and it is encouraging to see recognition for the contribution made by such industries to the UK economy. This award for Collaborative Research and Development has enabled us to kick-start a commercially viable but inherently high-risk project, and we can’t wait to get going with our partners.”

Either way, it's fairly progressive for a games company to class themselves under "creative industries"; most stay pretty aloof from the label because they see it as only applying to small, local artisanal businesses.

W dzisiejszych czasach deweloperzy są zainteresowani nie tylko olśniewającą, wysoce realistyczną grafiką. Chcą gier, które wciągają graczy do wirtualnego świata. Aby osiągnąć pełne złudzenie rzeczywistości, środowisko gry powinno być maksymalnie realistyczne, zaś postacie muszą poruszać się i oddziaływać na umieszczone w środowisku obiekty, co z kolei powinno mieć wpływ na rozgrywkę. Nadchodząca gra Crysostasis: Sleep of Reason, interaktywna kombinacja horroru i thrillera w perspektywie pierwszej osoby, jest jedną z ciągle zwiększającej się liczby gier wprowadzających technologię NVIDIA® PhysX™. Dzięki temu atmosfera jest o wiele bardziej realistyczna - przepełniona strachem.

“Dla Cryostasis: Sleep of Reason, głównym założeniem jest podkreślenie wizualnych efektów dzięki żywemu i interaktywnemu środowisku, które wpływa na poziom realizmu doświadczanego przez graczy,” powiedział Darryl Still, dyrektor wydawniczy w 1C. “Technologia NVIDIA PhysX pozwoliła nam na stworzenie tej przerażającej i wysoce interaktywnej historii.”

Z silnikiem fizycznym NVIDIA PhysX wirtualny świat Cryostasis: Sleep of Reason ożywa: ubrania mogą być zamrożone lub rozmrożone, rozbite szkło staje się bronią, której należy unikać, inne obiekty, takie jak pudła, beczki i rury kanalizacyjne, w momencie postrzału lub zniszczenia, zaczynają żyć własnym życiem. Technologia NVIDIA PhysX, składająca się z silnika fizycznego, API i oprogramowania middleware, jest najbardziej interaktywnym silnikiem fizyki i wchodzi w skład ponad 140 tytułów przeznaczonych dla Sony Paystation 3, Micrsoft Xbox 360, Nintendo Wii i PC.

Wykorzystując komputer kasy PC, technologia PhysX wykorzystuje moc zarówno procesora, jak każdego, zgodnego z CUDA, procesora obliczeń równoległych, czyli również karty graficznej od serii NVIDIA GeForce 8 wzwyż. Dzięki temu można obsłużyć od 10 do 20 razy bardziej skomplikowane graficznie środowiska niż bez zastosowania takiego procesora graficznego GeForce. Jedynie technologia PhysX jest w stanie wykorzystać w pełni architekturę CPU oraz  GPU i zapewnić maksymalnie realistyczne doświadczenia użytkownikom. . Wszystkie procesory graficzne serii GeForce 8 i nowsze obsługują technologię CUDA, dzięki czemu PhysX ma do dyspozycji ogromną, ponad 80-milionową bazę procesorów do obliczeń równoległych ogólnego zastosowania.

“1C i Action Forms, deweloperzy Cryostasis: Sleep of Reason, wyprodukowali grę, która niezaprzeczalnie może zostać nazwana najbardziej przerażającą grą na PC” powiedział Roy Taylor, wiceprezes NVIDIA do spraw kontaktów z developerami. “Gracze pokochają tę mieszaninę horroru i powieści science-fiction, która wrzuca ich na pokład lodołamacza o napędzie nuklearnym, około roku 1968. To jest gra, w którą będziesz musiał grać przy zapalonym świetle!”

Cryostasis: Sleep of Reason planowo pojawi się na rynku pod koniec 2008 roku. W celu uzyskania większej ilości informacji, odwiedź http://nzone.co.uk/object/nzone_cryostasis_home.html.

If you complain about deployment and usabilities of Oracle Enterprise software, you just know the tip of an iceberg.

When you are (God forbids) unlucky enough to get hired as a Senior Software Developer for Oracle, you will see the full horrible iceberg.

First of all, their enterprise software architecture is bad, and based on all the principles of "How to write slow and unreliable Java code". They use EJB, RMI and all distributed technologies unnecessarily, for no particular reason, except to amuse themselves, and torture their customers.

Second of all, a lot of Oracle enterprise applications claim to be J2EE applications, but contain a lot of Active X and proprietary javascript code for Internet Explorer, so they run only with Internet Explorer.

Third of all, they have very bad intergration strategy between Oracle products, so some Oacle products run very well (well here means relatively less bugs) with every other Application Server, except Oracle Application Server ;-)

Forth of all, they don't have good practice about Refactoring, Code review, Test first Development, only have theory, so the quality of Oracle's code is terrible.

Fifth of all, they have a very funny build process for J2EE application, which involves 10 different tools, from simple javac to Ant to Unix shell sh, m4 interepreter to Cruise Control, perl script, yapp and God know what else. But I swear that one day I really counted them, and there were 10 different things in all. Why the hell they cannot use Ant and Cruise Control, or if they must, use either Perl or Sh script? But they use 10 different things. Thanks God they don't include C# and Visual Basic into the build process.

Sixth of all, they don't have incremental build for some enterprise applications, so each time a developer change some thing in one file, he has to build the whole thing, and deploy the whole J2EE app again.

Seventh of all, Oracle Application Server is the second worst J2EE application server in the whole industry. (The worst is IBM Websphere). Even some Oracle enterprise products cannot be deployed reliably on OAS, while they can be deployed fairly easy on Weblogic or any other things. The performance of OAS is terribly bad, although they advertise something else on Oracle Website. And the Management Console is a typical study case about "How to design bad User Interface".

The last, but not least, that the team spririt in Oracle development team sucks. I don't even want to go into the details.

Of all other things, Oracle Collaboration Suite, Oracle iProcurement and Oracle HR tools ..., I think Oracle produces those kinds of software to take revenge on their customers, make their lives miserable. There is nothing that is more difficult and inconvenient to use than those Oracle hacky wacky products.

So except database which has been developed since Larry Ellison's time, all other Oracle products suck.

From Google:

So why are we launching Google Chrome? Because we believe we can add value for users and, at the same time, help drive innovation on the web. All of us at Google spend much of our time working inside a browser. We search, chat, email and collaborate in a browser. And in our spare time, we shop, bank, read news and keep in touch with friends — all using a browser. Because we spend so much time online, we began seriously thinking about what kind of browser could exist if we started from scratch and built on the best elements out there.

We realized that the web had evolved from mainly simple text pages to rich, interactive applications and that we needed to completely rethink the browser. What we really needed was not just a browser, but also a modern platform for web pages and applications, and that’s what we set out to build. On the surface, we designed a browser window that is streamlined and simple. To most people, it isn’t the browser that matters. It’s only a tool to run the important stuff — the pages, sites and applications that make up the web. Like the classic Google homepage, Google Chrome is clean and fast. It gets out of your way and gets you where you want to go.

From the Associated Press:

Google will begin distributing its own browser in a move likely to heat up its rivalry with Microsoft.

The Internet search leader confirmed the long-rumored browser in a Monday posting on its Web site. Google said the free browser, called "Chrome," will be available for downloading Tuesday.

The browser represents Google Inc.'s latest challenge to Microsoft, whose Internet Explorer is used by nearly 75 percent of Web surfers. Google has been concerned that Microsoft will try to program Internet Explorer in a way that makes it more difficult for Google's search engine to attract traffic.

From GigaOm:

Google in a blog post on their website has acknowledged the existence of Google Chrome, a browser that the company will be releasing tomorrow. Kara Swisher has confirmed the existence of Google Chrome, a browser developed by the Mountain View, Calif.-based search company. The rumors of the browser were reported earlier on Google Blogoscoped, which received a comic book that outlined the key features of the browser.

• It is based on Webkit and will include Google Gears.
• It includes Javascript Virtual Machine called V8 that was developed by a team in Denmark.
  
• It accelerates the Javascript performance and is multi-threaded.
• It has tabs, auto-completion, and a dashboard type start page that can help you get going to the web services you need. Opera has such a dashboard.
• It has a privacy mode that allows you to use the machine without logging anything on the local machine.
  
• It might be similar to a feature called Incognito in the latest version of Microsoft IE.
• Malware and phishing protection would be built into this browser.

From BoomTown:

In its most frontal and aggressive attack on Microsoft yet, sources with knowledge of the project said Google is preparing to unveil a new browser–ready for download to users as early as tomorrow–to try to loosen Microsoft’s iron grip on the most important piece of software to navigate the Internet.

In addition, Google Blogoscoped has published a comic book that Google is apparently using to explain the technical aspects of its open-source browser, which is called Chrome.

From CNET:

While the illustrations, created by cartoonist Scott McCloud, were not announced by Google, they do contain the quotes and likenesses of 19 Google developers.

CNET News.com Editor in Chief Dan Farber's analysis of Google Chrome Monday was this: "It would be in line with other Google open-source projects, such as OpenSocial and Google Gears. Creating a competitor to Firefox, as well as Internet Explorer and Opera, could spur more innovation."

"Open sourcing the code is a smart way to avoid the 'Google wants to take over the world' fear, but it seems that Google has ambitions to create a comprehensive Internet operating system, including a browser, applications, middleware and cloud infrastructure."

From InformationWeek:

Yes, you read that correctly. Google is taking a major swipe at its competitors with the imminent launch of Chrome, a new Web browser based on Webkit. Thus marks the beginning of a new phase in the browser wars.

Kara Swischer at The Wall Street Journal got perhaps one of the biggest scoops of the year. She spoke to some people familiar with some of the projects Google is working on. Those sources say that Google is set to unveil a brand new Web browser that will be available to everyone as early as tomorrow (Tuesday).

Not only is Google going announcing a new browser, but it is making the announcement with a comic book. That's hot.

Google has talked the browser talk for years. The last time I heard anything formal about it from the Google camp was nearly a year ago. Looks like Google is ready to walk the browser walk with Chrome.

A more disturbing thought than the above one is when we have the Data, the technology and the willingness to do good, but we are unable to do it because of the ubiquitous "SYSTEM DOES NOT ALLOW IT" message. The System that I am talking about here are the systems that connect data generated across different sub - systems across the world. A country does produce food that is more than it can consume, and is willing to give it to those who are perishing, but cannot do so as they do not have the information pertaining to it.

So we come at a point where it turns out that the key to success, or rather the key to prosperity is INFORMATION. Then what stops us from using the information that is just lying there?

The answer to this is the sheer size of the datum that makes it difficult if not impossible to use it. Also the fact that these bits and pieces of information are generated across disparate platforms does not help. Being sane minded, we cannot ask all the information vendors to use the same platforms and representation of data everywhere. So what do we do?

The Answer is effective integration of information - Effective Middleware. The point lies in the integration of all the vendors and linking them together. Making information that needs to available public so that companies who believe in corporate Social responsibility start diverting there attention on this area.

Imagine a world where Scientists predict well in advance about a natural disaster that might happen at place X. This data is made available to specific agencies who are ready with the homework for disaster recovery as well as goverment organizations. The summary of this entire data is then made public for use by NGOs who take over the rescue and recuperation work - The key lies in efficient and timely distribution of information.

If Information is too big a world to handle for us, lets start with a smaller entity and call it Data. And if you are reluctant with Data too ... How about something smaller than Data - How about 1 precise piece of Information - A DATUM.

WebSphere MQ stuff

It's a year of anniversaries. Apart from IBM Hursley hitting 50 (reminding me that I've yet to post my Spitfire photos from the celebratory open day weekend), IBM Warwick is 30 and WebSphere is celebrating 10 years. WebSphere MQ was formerly called MQSeries, of course, and has been around a few years longer than the "parent" brand, with a 15th birthday this year.

I'm sure the numbering is merely a coincidence, but there's a good article on IBM developerWorks entitled The top 15 WebSphere MQ best practices.

WMQ reached version 7 this year. I had some very positive experiences with the alpha version of the product last year, although I've not yet had a play with the GA release. The new HTTP support is particularly interesting from a Web 2.0 perspective, and I keep meaning to build some demos around that that feature.

In related news, WebSphere MQ now has a Twitter account, so if you want to catch the latest news and announcements you might want to follow that.

I picked that last nugget up from my friend and US colleague T.Rob Wyatt, who has been blogging for a while now... T.Rob is an expert who is absolutely worth following if you work in the MQ space. He's also pointed out that there's a new blog for IBM's new Managed File Transfer product which was announced last month.

Other messaging-related notes

For some non-IBM messaging middleware updates, just to note that 0MQ (ZeroMQ) sounds intriguing (via Matt Perrins, who notes that it is nothing to do with Project Zero). I've done a lot of work with clients in the financial sector in particular, so I'll be interested to see how this develops. One of the nice things about my other "pet" product, WebSphere Message Broker, is that it sits in the sweet spot of connectivity between different transports and protocols, so I guess I'll be looking at how to make things talk to one another if 0MQ takes off.

Elastra aims to help you easily overcome the challenges of scalability in the Cloud, by making it seem almost transparent to you. Their "White Paper" is a good read, and discusses the problems of scaling as well as Elastra's solutions.The following two pictures, taken from Elastra's website summarize what they accomplish.

[gallery]

Elastra provides:

Industry-standard database and application infrastructure in the Cloud that is:

• Easily architected, configured and deployed in a complete, clustered, run-time environment
• Elastically scaled with automated system monitoring and management
• Priced pay-for-use
• Delivered on-demand

Right now, Elastra runs on Amazon's infrastructure, Amazon Elastic Compute Cloud, which provides scalability within minutes on a pay-as-you-go basis, as well as its Amazon Simple Storage Service. It would not surprise the GoogleGazer to see Elastra support some of the other platforms that we mentioned in our previous post. Mean time, they have been garnering an impressive array of clients, and support PostgreSQL, the world's most advanced open source database, and MySQL (now owned by Sun). Besides Amazon, Elastra partners with EnterpriseDB, the world's leading provider of enterprise-class products and services based on PostgreSQL, Postgres Plus and Postgres Plus Advanced Server.

Expect to hear more about them.

Dalla solita architettura dei prodotti di operation (server centrale e agenti per ogni oggetto da gestire), lo contraddistingue l'essere fondato su XMPP (Extensible Messaging and Presence Protocol) - specifica IETF (Internet Engineering Task Force) per lo streaming di strutture XML.

Vertebra usa Ejabberd (server XMPP/Jabber sviluppato con Erlang) come server centrale: prestazioni elevate sono garantite anche con decine di migliaia di connessioni contemporanee.

Un'unica istruzione è sufficiente ad individuare tutti gli agenti coinvolti e ad avviare l'esecuzione, in parallelo. Per coordinare le operazioni, inoltre, è previsto un workflow.

Trovo questo progetto interessante anche per altri usi: una dorsale fondata su XMPP collega punti di controllo in grado di eseguire operazioni su "oggetti" che il concetto di risorsa astrae.

Beginning September 1, 2008, Oracle will no longer offer WSG with EnterpriseOne Tools. However, existing users will still be able to access WSG via the Update Center. In addition, Oracle will provide Premier Support for the offering through October 1, 2010. This means that WSG will continue to receive updates, fixes, and certifications for new EnterpriseOne releases. After October 1, 2010, WSG will move to Sustaining Support, which provides technical assistance and pre-existing fixes for known issues.

As for XPI, many of you may know that PeopleSoft ceased offering these interfaces with EnterpriseOne Tools shortly before Oracle acquired the company. Once Oracle took over, it put the final XPI release — which shipped with EnterpriseOne Tools 8.94 — on Premier Support. In last week’s announcement, Oracle extended Premier Support for XPI 8.94 to October 1, 2010. After that date, XPI move to Sustaining Support along with WSG.

Hello EnterpriseOne Business Services!

Oracle has decided to sunset these technologies for a simple reason. The vendor’s strategic platform for application integration going forward is neither WSG nor XPI. It is the EnterpriseOne Business Services gateway that the software giant delivered with EnterpriseOne Tools 8.97. Unlike WSG and XPI, which include proprietary integration methods and hard-wired connections, Business Services complies with industry standards and the loosely coupled integration paradigm of today’s service-oriented architectures. Business Services is also a key component of Oracle’s Application Integration Architecture (AIA). As result, Business Services can publish, consume, and administer AIA-based web services as native objects, something that WSG and XPI cannot do.

Now that the phase-out of WSG and XPI is official, EnterpriseOne customers who are using these technologies should make concrete plans to migrate off them by 2011 at the latest. Any migration will involve the deployment of EnterpriseOne Tools 8.97 or higher. In addition, customers running OneWorld Xe or EnterpriseOne 8.0 will need to upgrade to current EnterpriseOne releases. Just as importantly, developers should retrain themselves on Oracle JDeveloper, as this is Oracle’s strategic platform for working with Business Services objects.

Fortunately, Oracle has already provided some tools for the migration process. The Update Center offers web services for downloading that cover most of the functionality found in WSG. Information about Business Services can be found on the EnterpriseOne SOA Enablement site along with a Red Paper about migrating from WSG to Business Services.

Of course, this web site and the team at Andrews Consulting Group stand ready to help you with your migration efforts. To learn more about Business Services and AIA, read the articles we have written on both subjects that are listed below. If you want to discuss your migration options, send an email to our JD Edwards team or call us at (800) 775-4261. Feel free as well to leave your thoughts about Oracle’s action in the comment box below.

The story behind the unusual alert was broken yesterday by Eric Maurice on the Oracle Global Product Security Blog. For those of you who do not know him, Maurice anchors this blog and has made it one of the best sources of information about securing Oracle products on the web. As Maurice explained in yesterday’s post, both the vulnerability and the code to exploit it was posted on public forums before it was sent to Oracle (a definite "no no" that separates ethical hackers from the black hats of the business). To make matters worse, the exploit code hit the forums shortly after Oracle released its last Critical Patch Update on July 15. This is forcing Oracle to issue an out of cycle security update.

If you do not subscribe to the feed for the Oracle Global Product Security Blog, I would encourage you to do so. Its timely warnings could save you from a nasty breach of your JD Edwards applications.

- Mobile use cases: In case of some solutions like Field Sales and Service Management, Logistics, Delivery Management, the use cases are very well defined and hence easy to implement. as such, these are the first ones to get mobilized and several companies have been doing that for years. However, there are several others where the mobile use cases have to be really thought through and vetted.

- Integration with existing systems: Either mobilizing existing data or capturing data at customer location, enterprises have to integrate and extend the existing systems to support mobility. This typically involves custom development. A number of vendors have developed connectors to popular systems like SAP, Oracle, etc., however, there is some degree of customization required to support the enterprise specific use cases. 

- Security: Another big issue with mobility is the security headache of so many disparate devices trying to access the enterprise data. A lot of effort are ongoing into addressing this with integrated device management solutions. Sybase did announcethe first integrated firewall and anti-virus management solution mobile devices under its Afaria brand of device management solution.

- Total Cost of Ownership (TCO): The aforementioned integration and security solutions come at a price which increase the TCO for an enterprise mobility solution. In addition, most of the mobility middleware solutions themselves require a lot of consulting expertise to implement successfully without customization.

- Time to market: Considering all the integration, customization and security resolution, the time to market will be extended. Certainly the prebuilt connectors help speeding the development up, but still the average time to market to get these solutions out are upwards of six months.

With all these challenges, enterprises certainly need to plan their mobility strategy carefully and select the right vendors for their needs.

Next Stop…WebLogic?

Last week, I posted a review of Oracle’s plans to integrate BEA products into its Fusion Middleware portfolio. As the review stated, Oracle’s middleware roadmap raises many questions about the role that BEA products will play in the Oracle Technology Foundation for EnterpriseOne. While we are still working to get definitive answers to those questions, sources inside Oracle have confirmed that there are no plans to force EnterpriseOne customers to use BEA WebLogic Server. If you are running Oracle Application Server or IBM WebSphere Application Server, you will continue to receive support.

That said, sources close to the JD Edwards team are saying that the team intends to follow Oracle’s lead when it comes to adopting those BEA products that have been designated as "strategic". As such, EnterpriseOne users should expect that selected BEA products will become part of the Oracle Technology Foundation. Rest assured that we will be on the lookout for further developments on this front and will post new articles as information becomes available.

JD Edwards World Picks Up the Pace

Now that Oracle is past its quarterly "quiet period" for discussing financial results, we’re learning that the company’s fourth fiscal quarter and fiscal year 2008 were quite good for JD Edwards World. In a recent briefing for its business partners, JD Edwards executives revealed several significant wins for World in new accounts. They also unveiled a new "Green sales initiative" that will promote both World and EnterpriseOne during fiscal year 2009. At the same time, JD Edwards World General Manager John Schiff wrote an open letter to the World community. In the letter, Schiff states that the World community has never been as vibrant and active as in recent years.

It is gratifying to see confirming evidence of the growth trend for World that we discussed back in May. It will be interesting to see how the Green sales initiative plays out in the coming months.

A Better WebSphere?

If you are running your EnterpriseOne web tier on an IBM System i using WebSphere, check out the latest paper from the IBM Oracle International Competency Center that we just posted to our white papers section. The paper compares the performance of the latest WebSphere Application Server 6.1 release to that of WebSphere 6.0 when running EnterpriseOne 8.12. Unlike WAS 6.0, which runs on a 64-bit JVM, WAS 6.1 uses a streamlined 32-bit JVM. This is one reason why WAS 6.1 delivered faster EnterpriseOne response times than WAS 6.0 while using less memory and fewer CPU cycles.

New EnterpriseOne Tools Update on Tap

Last week, Oracle announced the availability of EnterpriseOne Tools 8.96 Update 4. The update, which is the final maintenance release for Tools 8.96 contains all of the fixes in maintenance packs 8.96.0.1 through 8.96.3.3 along with new fixes of its own. With the release of Update 4, EnterpriseOne Tools 8.96 now moves into "sustaining support" mode in which no further updates are released. To learn more, log into the EnterpriseOne Update Center on the Oracle Customer Connection web site.

Oracle UCM Goes Midsize

If you ever took a look at Oracle Universal Content Management (formerly known as Stellent UCM) but flinched at the high price, I have news for you. Last month, Oracle announced UCM Standard Edition, a version of the product that strips out some of the advanced features in exchange for a considerably lower price. While Oracle UCM carries a list price of $115,000 per processor, UCM SE weighs in at $57,500, a 50 percent reduction. Considering Oracle’s reputation for deep discounting, street prices for the product will be considerably lower. One nice feature of UCM SE is that it can be easily upgraded to the full version without uninstalls or reinstalls. To learn more, check out Oracle’s latest Midsize Business Newsletter.

Don’t Thank Me…Just Send Money!

The next time that you get someone from another company interested in Oracle products, your good deed could earn your company some cold, hard cash. Oracle has unveiled an initiative under which companies can receive 5 percent of net software license deals — up to $50,000 — when they refer other firms to Oracle.
