It's a busy weekend here in India with the General Elections 2009 verdict to be out tomorrow. And while that happens, I'm going to journey towards a peaceful destination for spending a restful weekend. To all those who intend to follow the India 2009 Election Bulletins closely, here's wishing a very interesting weekend!

And guess what, this massive amount of data (talk about billions of pages and growing) is hosted in a Sun MD and employs Sun OpenStorage. Read more about the 'Internet In a Box' here.

For reference, the deployment scenario is depicted in the diagram below:
The phase I of implementation involved integrating Sun's IDM with OpenSSO. The following was the objective:
[\*] Configure OpenSSO Enterprise to protect Identity Manager, and to allow single sign-on login to the Identity Manager user and administrative interface.
[\*] Configure Identity Manager to provision users and roles to OpenSSO Enterprise.
To achieve the above,there is a neat documentation available here.
Once I got the above integration of IDM and OpenSSO functional in our set up, users could be provisioned from Sun Identity Manager to the 'idm' realm in OpenSSO (which finally gets stored in the DSEE 6.x configured as the User repository for OpenSSO).
The actual reason for adding an entry on my blogs around this set up is to express my excitement on discovering the ease of integrating GlassFish WebSpace Server with OpenSSO. I'd reiterate those steps performed to make the GlassFish Web Space Server (installed in one zone of Solaris 10 OS) contact OpenSSO (installed in another zone) for authentication. I presume, this exercise can be performed in a matter of few minutes. So set your stop watch and get going:
 Unzip Ant and GlassFish WebSpace Server.
 Set ANT_HOME variable to point to the directory location of new version of ANT.
 Goto webspace_dir/glassfishv2 directory and run the following command:
ant -f setup.xml
 Once the above step is completed, goto webspace_dir/glassfishv2/bin directory and start domain:
 Upon successful completion of above step, open a browser and access the following URL:
If any of the above steps seems ambiguous, please read the installation instructions here.
Once the GlassFish WebSpace Server page is up on the browser, login using the credentials of Administrator (email@example.com/admin), click on the Control Panel -> Settings -> Authentication -> OpenSSO. Following page is what you would see on your browser.
On the page as displayed above, following is the information filled in to make the WebSpace Server contact the 'idm' realm in OpenSSO for authentication of users. Not only that, on successful authentication with OpenSSO, WebSpace Server populates the user information from OpenSSO in its database (HSQL by default)!
Glassfish WebSpace Server installation,configuration and integration with OpenSSO is such a pleasant experience that I invite you to try it and experience it for yourself.

I'm glad to have got an opportunity to speak to a larger audience on a grand occasion as Sun Tech Days and that too on a very useful Solaris 10 feature, one among several Virtualization Solutions from Sun. To know more details about a training on Solaris Containers, click here. In another location within the Sun Tech Days 2009 venue, my friend Stacy delivered a full day seminar on the new and exciting JavaFX technology. Detailed description about a JavaFX course can be found here.
Due to several last minute onsite registrations, the Student Kits, containing several materials including OpenSolaris and Netbeans DVD went out of stock and some delegates had to go back without it. While we arrange for its shipment to delegates who didn't get a Student Kit during the event, we would wish to remind all that OpenSolaris and Netbeans could be downloaded from the website as follows for immediate use: (i) OpenSolaris (ii) Netbeans .
Like all previous editions of Tech Days, the one that concluded yesterday also offered me several fond memories. The photograph below is just one of it:

As cloud computing takes the center stage, it'd be interesting to follow Matt here to hear from him, directly and promptly, the developments on Cloud Computing at Sun. On one of his slides this morning, Matt listed the attributes of cloud (One Service Fits All, Virtualized Physical Resources, Self Provisioning, Easticity, Pay Per Use,Programmatic Control), in another he talked about Cloud as: (i)Software as Service (SaaS), (ii) Platform as Service(PaaS) and (iii)Infrastructure as Service(IaaS) and finally he explained how developers could utilize the power of cloud for developmental activities,scaling up and down the hardware that they need, as and when they need, build their project on cloud and collaborate with their project mates sitting across different Geographical location. In a stunning demonstration, within a matter of few mouse clicks, all of us got to see a Solaris Desktop - sitting somewhere in a public datacenter- popping up on a Windows laptop. It was exciting! No wonder, the demonstration invoked a loud applause from the audience.
In addition to talking about how a startup company could rely on Cloud rather than building their own data center, Matt also introduced us to Project Kenai and Zembly.
S D Shibulal, COO of Infosys and Prof Deepak Phatak were felicitated by James Gosling in the presence of Anil Velluri, VP and Managing Director of Sun India. When invited to speak, Prof Phatak said, "I'm a teacher. My few minutes could span several hours." Prof Phatak said in his speech how excited was to see so many developers paying fees for an event like Sun Tech Days and gathering under one roof. He also mentioned that in the past, India had more number of downloads than uploads (in terms of contributions to the OpenSource community) and that he's seeing a change in that trend off late. Prof Phatak's speech was short, but inspiring and touching.
All right, while you try and figure out a weird talent that you possess and probably start polishing it to try and gain a Java Jacket next year at Sun Tech Days, let me hit my bed and sleep, for I have a lengthy speech to make on the last day of Sun Tech Days 2009, tomorrow.

What followed then were some useful demonstrations on technologies like OpenSolaris, JavaFX and Java TV.
Anil Valluri,VP and Managing Director of Sun India, gave the inaugural address, briefing about Sun, its business model and other related topics, and concluded his speech by inviting James Gosling on to the stage. It wasn't surprising to hear a loud round of applause as Gosling walked his way up on to the stage.
Gosling covered a wide range of topics: the evolution of Java from a slow interpreted language in the mid 1990s, its performance improvement over a period of time, the latest release in the form of Java 6 Update 12, the new JavaFX technology, the Glassfish, the Netbeans 6.5 and much much more.
He mentioned the staggering statistics of 15 million downloads of JRE a week, talked about the Java enabled Oyster cards (he pulled out one from his pocket while talking about this) being used in the London Underground by every single train passenger, his work with the rocker Neil Young on the Java-enabled, hybrid-electric Lincoln convertible, why a virus free Java is a preferred choice for applications that require secure transactions over the network and performed a number of demos on JavaFX.
It was quite a charm when he said he was the guilty party behind developing Emacs editor 32 years back or so, which later became GNU Emacs, but urged all present day Emac users to stop using it, as things are not the way it was three decades back and that present day IDEs are intelligent enough to know a lot about the programs that programmers write. Well, here is an IDE worth trying: Netbeans.
Gosling's keynote, needless to say, was an absorbing session.
Several break out sessions on various Sun Technologies followed James Gosling's keynote. It was a good first day and it's only going to get better.

Below you would see the entire audience who dropped in for the SA 355 S10 course concluded at Hyderabad on Saturday, the 7th February 2009:
I know I would need a few days voice rest to recover from this temporary voice loss. At times like this, I tend to rely a lot on pictures and writings to communicate. So if I've to tell you now, what I spoke at Hyderabad before my voice vanished on the last day of training, perhaps the picture below will speak out for me. Click on it to know more:
Have a good week ahead!

On 8th, I felt slight weakness in my voice. By evening, I could speak nothing. I still had four days of training left, when an ENT advised me for a complete voice rest. Calling off the batch was an easy option, but not the best one. Hence on Tuesday, my training participants found in the classroom a whiteboard full of instructions, conveying to them clear and loud about an 'Instructor Led Voice-less' training that they were about to face! With a hope of some divine intervention, I continued from where I left on day one and it began to work in my favour. I have never written so much continuously on a white board ever before and I have never played such lengthy dumb charades either . For three full days (almost), I took sessions, without uttering a single word! Occasionally, someone would volunteer to explain to the whole class, concepts that required repeated explanations. It was tough, but it was immensely satisfying. I am not saying that I would ever want to have an experience like this in future, but then this would stand as one of my memorable sessions for obvious reason. I extend my heart-felt gratitude to folks in the picture below for their extreme cooperation in helping me complete this session on a very satisfying note. Thank you folks!
Those who aren't Field Engineers, but administrators of Sun Fire Midrange Servers and are on the look out for a Sun Training, check out this course. Wishing you all a restful weekend!

Through a teach back session, in a matter of an hour, I got to hear from them, all that they learned in five days time. Their performance was captured and that's what you see below:
I'm certain, some day or the other, there'll be a part 2 for this story.
