President Lula at FISL 10

President Lula (President of Brazil) came to FISL. This is probably the first time ever that a President of a nation has visited an Free and Open Source Software conference any where in the world.

Here is a picture taken by Ludovic of the President wearing the OpenSolaris cap and holding a OpenSolaris t-shirt.

Heres a video of the president by Deirdre with the Porto Alegre OpenSolaris User group folks.

Mukti 2009

I was invited to Mukti 2009 last weekend for talking on Sun Open Source technologies I reached Durgapur early in the morning after sleeping for one hour the previous night due to a flight delay. I was supposed to talk on Sun SPOT, OpenSolaris and OHAC.

The first talk was on Sun SPOT and it got delayed for about half an hour. I had some fun in making the laptop work with the projector and for a change this time the projector refused to work with Vista but worked flawlessly with OpenSolaris 2008.11. Now that was a real surprise. If you are wondering why Vista, that is because I didn't have the Sun SPOT manager for OpenSolaris and hence had to demo using Windows. The SunSpot talk was attended by about 80 to 100 people. They really enjoyed the SunSpot talk and many of them wanted to try it out. Alas, its not sold in India but I pointed to NIT Durgapur Sun CA Abhishek who has a kit.

My next talk was on OpenSolaris and what makes it interesting. Most of the talk material was provided by Roman Strobl. Since I was running short of time, I didn't do any of the demos. Instead I showed them a video made by Roman about the new features of OpenSolaris. I guess the most interesting feature was Time Slider. Hopefully some of them will try experimenting with OpenSolaris.

I had to drop the OHAC talk as I had run out of time.

Solaris Cluster 3.2U2

Solaris Cluster 3.2U2 got released yesterday. This release contains the zone cluster feature. Thus one can make clusters made up of zones. Now isn't it really cool. Well I find it even cooler since I have been working on zone cluster project :)

Top New and Enhanced Features

1. Virtualization

Solaris Cluster includes extended Solaris Container support for applications such as Oracle RAC databases enabling highly available consolidated services at lower cost.

  • Solaris Container Cluster: Allows the creation of fully isolated virtual clusters based on Solaris Container virtual nodes. Distributed applications such as Oracle RAC databases and in the near future solutions such as MySQL can be run in separate virtual clusters. Multiple databases or database version can be consolidated into one physical cluster for highly available consolidated service.
2. High Availability

Solaris Cluster is enabling increased High Availability levels through more monitoring capabilities and improved configuration verification tools.

  • Quorum Monitoring: Provides continuous monitoring of all types of quorum devices including quorum server and sends notifications about failures, enabling proactive maintenance.
  • Configuration Checker: Checks for vulnerable cluster configurations regularly and rapidly, limiting failures due to mis-configuration throughout the life-time of the cluster
3. Flexibility and Ease of Use

Solaris Cluster is improving flexibility and ease of use and support more configurations.

  • Optional Fencing: Fine-grained control of the usage of fencing enables use of shared storage by systems outside the cluster and inclusion of new storage with limited or no support of SCSI based fencing.
  • Software Quorum: Disks that do not support SCSI reservation can be used as quorum disks thanks to a new quorum device protocol.
  • Optional dedicated partition: a lofi device can be used on Solaris 10 for the Solaris Cluster global-devices namespace as an alternative to a dedicated partition.
  • Exclusive IP in Solaris Container: supported with Solaris Cluster HA agents.
  • Oracle Data Guard: supported with Solaris Cluster Geographic Edition.
  • IPsec: supported on the cluster interconnect.
  • Sun StorageTek Availability Suite: supported in Solaris Container with Solaris Cluster Geographic Edition.
4. New supported applications and agent features

Solaris Cluster is supporting even more applications such as Informix IDS and applications versions out-of-the-box to facilitate integration and deployment.'

Second Bug Fix to OHAC

Lalith On 16th Jan 2009, the second OHAC bug fix, contributed by Lalith Suresh, student and Sun Campus Ambassador from Malaviya National Institute of Technology, Jaipur,  went into the OHAC gate. I was the sponsor for this bug.

I first met Lalith in the CA induction program in Bangalore and later on came to know that he was very interested in OHAC. As a part of the induction program he had given a talk on clustering and he is also working on HA-Cron and HA-Zabbix agents for OHAC.

OpenSolaris 2008.11

At last OpenSolaris 2008.11 got released officially on the 10th of December. I have been playing with the release candidate build for quite some time on VirtualBox. Finally I installed it on my laptop.

The first things which really impressed me were the new installer screenshots. They looked lively and fresh.  After the installation was over, the wireless and the sound worked flawlessly. I had to install the Marvel Youkon driver myself. The Firefox which came did not come with the flash plugin which I had to install myself. Then I tried downloading packages from the IPS repository. I downloaded OpenOffice 3.0, Netbeans 6.5 and SunStudio Express and SongBird. Now I have a fully functional desktop.

I am yet to try out the new features like Time Slider and some other cool features but you can view the video on the new features of OpenSolaris at

Happy exploring OpenSolaris 2008.11

BOJUG meet on July 26

Yesterday Bangalore was rocked by a number of bomb blasts. Today we had a BOJUG meet. I was not even sure how many people would turn up but thankfully about 10 people were there. I was happy to see the brave souls who did not let yesterdays violent incident affect their lives.

Sriram gave a talk on  "Continuous Integration - What you need to know before implementing it". It was a very interesting talk on software development and how a little bit of discipline could help in producing bug free software. A lot of the stuff is already known, but not followed. I hope one day it is followed in my team. Hopefully we will then stop having those inadvertent build failures and regressions.

And now the surprise. I also gave a talk on Solaris features. Since Sriram was late, I was filling in. I gave a talk on Solaris history and features and told people how many of the server grade features are becoming necessary for the desktops. One day I will give a more Java related talk here. Lets see how it goes.

Many of you always wanted to see me in a BOJUG or BOSUG group picture. You can see me above. Anil took the picture above.

And heres the group picture taken by me which has Anil.

As I write this blog, news is floating in of serial blasts in Ahmedabad. I really do not understand who is gaining from all this but the poor and innocent people are the ones who are suffering.

BOSUG meet on 12th July

The last BOSUG meet was  debugging and observability features of OpenSolaris excluding DTrace. Moinak and Sanjeev spoke about mdb, ptools, truss. What amazed me was that most people were hearing these for the first time.



Angad talking about the new Belenix website

The other topic was the new belenix website by Angad. He has done a phenomenal work. Hats off.
