Sun Tech Days, Day 2

Honestly I never expected this. From the various conferences I have attened, I see that attendence on the day 1 will be full. Participants will attend the conference, visit all the stalls, collect all the goodies, Free CDs in all the stalls, collect their delegate kit and go. Not all turn up for the next day. Hardly 50% turns out for the second day.

But Today I was zapped. When Jim Huges CTO of Solaris was talking about OS futures in the main hall, I saw a packed audiance. I was amazed to see such a response from the Developer community. Jim Spoke about the Horizantal Scaling, Vertical scaling challenges in the coming future and what operating systems should do to address this. 

Vijay Anand, VP Oracle was the guest speaker. He spoke about the SOA, EJB3.0. It was a plesent surprize for me to see Vijay  there.

Unlike yesterday, we had lot more space for Solaris Demos. The Netbeans Contest team were done with the contest on Day 1. So we used that stall space to do solaris demos.

Solaris Track started with Madan's presentation on "Writing Highly Availabe application using Sun Cluster" The turnout was good for this talk. There was lot of questions and session was quite interactive.

University Track was a major hit. There was a huge queue in the pavilion area to attend this track. The hall capacity was about 1000. But even after the hall was full, I could see around 200-300 people waiting to enter the hall. Specially for the first talk on "Whats going to happen in the Next 10 years, and what you should know as a student Today" By Matt Thomson. I have taken couple of photos graphs.

Of all the Technical track presentation I attended today, I felt Sanjeev's presentation on ZFS was the best. He was able to make audiance understand the problems with the existing filesystem model and How ZFS is addressing them in a completely new approach.

After all the event, we had a First Hyderabad OpenSolaris User Group meeting. More than 100 turned up for this event. We had some guest from US, Jim Huges CTO of Solaris, Kathy Jenks, Director of Security, Frank Curran attending this USOG meeting.

Moinak spoke about the belenix and the experience he went thru while creating Belenix.
After the talk, there were some very lively discussion on Belenix and its futures, Opensolaris and the plans etc.

Tomorrow is a big day for me. Its OpenSolaris Day and I am program managing this event. It will be a long day for me. I hope there will be a tremendous turnout for this event too.

Sun Tech days, Hyderabad Day 1.


    This is my First Sun Tech day Event. This year Sun Tech Days is happening
in Hyderabad International Convention Center.

For the first time in Sun Tech days history, we are having a separate day for opensolaris.
It is scheduled on Day 3 i.e on Feb 23rd. I am program managing that event.
I flew from Bangalore on Feb 20th morning. We all had a tour of the venue on Feb 20th just to
make sure that we know what event is happening where and who is taking care of what.

I must say that this venue is just AMAZING. The hall where Keynote was supposed to happen
is really big. I think first time I am seeing such a big hall.
When I was walking through the convention center, I had only question in my mind all along.
Why don't Bangalore has such a center ? Well let our Chief Minister and other concerned
person worry about this. Lets come to actual topic Sun Tech days.

I was told that there were more than 4000 registration on Day 1. But I got the feel of what 4000
means for on the day. The hall was packed. It felt really good to see so many people coming to
our event (remember it is not free event. It is a event). Its not only these 4000 people.
People from Mumbai, Delhi and Pune are also listen to these Keynote on Day 1.
I was told that registration at these satellite cities are close to about 1000.
This brings a huge responsibilities on Us to deliver good talk, interact with these people, make them
understand our technology, convincing them on why it was worth their time and money spent in this event.

The Event started with an Introduction from Bhaskar Pramanik, MD Sun Microsystems, India.
He is one person whom I always consider as a good speaker. He knows how to grab the audience attention and he makes you listen to him all the time.
This talk followed by Guest Speaker for the event, Ramalinga Raju, Chairman, Nasscom.
He spoke about change management.
Then came the Keynote by our Executive VP Rich Green's Key Note address.
He gave a good foundation for the Sun Tech days and told developers what are they missing if they are not using Sun Technologies. I was very happy to see him mentioning about Belenix and BOSUG.

There was some cool Technical demos from Srikanth Ramakrishna, Simon Ritter and
others on various Sun Technologies after Keynote address.
This followed the actual talk track.
I was at the Solaris booth most of the time and talking to all the people who visited our stall and spoke about Solaris.
We had a quite a good discussion about Solaris Zones, SMF and ZFS with lot of people.

Solaris Track had a lucky Dip contest. All the people who had attended any solaris track presentation were asked to fill up a registration form. At the end of the day, A lucky winner was chosen by a lucky dip.
The prize for the winner was Acer Aspire 5100 with Latest solaris express installed. Venugopal from Tejas was the lucky winner.

The Day 1 ended with Famous Bollywood Singer KK performance for the audiance. He sang all his popular numbers and entertained the crowd.
I have taken lots of pictures during the event. I will post them soon.

Day 1 of FOSS.in 2006

FOSS.in 2006 began with a great style today.
Atul Chutnis gave a opening ceremony talk. It was kickstarted by lighting Diya.
As a practice for this event, Diya was lit by few community members across India.

Sun Microsystems is a platinum sponsor for this event. We have got 3 stalls to showcase our technologies.
I was little surprised to see so many sun employees today morning at 9 at the event.
All had come with great enthusiasm to setup the stalls and demos. We got all the machines up and running before the start of the events. Major credit for this efforts has to go to Pavan, Sanjeev, Jayakara Kini, Ravi Prasad, Dinesh, Ananth and Ramesh Katla.
They were very helpful in setting up the machines, configuring network for Grid, FMA and virutualization.

Compared to last time, this time crowd was little less. This was expected because the talks were more technical.
Last time most of the talks were to create awareness. But overall more than 1000 had turned for this event.

There was good number of people in the Sun stall. We had planned for Looking glass demo. We got that working the first stall.
Thanks to Vijay Gadre for giving us his laptop for this purpose. Lot of people played around with Looking glass.
Some were so excited that I could see them clapping.

ZFS demo also got the constant flow of people. Sanjeev and Nagki had put in lot of efforts to make the demo look cool.
The demo was using USB drives. So it was easy to pull out disk and show the data being consistent and available (for raidz and mirroring)
Lot of people got interested and were asking lot of questions on ZFS.

Java Opensource news had created great waves. There were lot of Java people to answer all the question. We had a Talk on OpenJDK today. The hall was packed. People were standing outside the hall and listening. Unfortunately I couldn't take the picture of that.

We had 3 BOFs today. 2 Dtrace BOFs and 1 netbeans BOFs.

Tomorrow Sun is having 6 talks lined up.

FOSS.in again

I still have fresh memories of our experience in last year's FOSS.in.
We created a great impact in FOSS community with lots of technical presentation and demos on opensolaris.
Atul Chutnis who is one of the main organizers of the FOSS describes our efforts in his own words..

<start>

Here is an organization that has been consistent in suprising the FOSS
community with lavish gifts of contribution of code.

They were Platinum Sponsors at FOSS.IN/2005, and they completely blew us
all away with their professional show of FOSS power, both in their well
arranged and extremely useful talks and tutorials, as well as their
amazingly well designed and informative stall at the expo.

And they blew us away even more with their release of OpenSolaris,
contributing a huge pool of valuable technologies and code to the FOSS
code pool.

A hard act to follow, but they did it, resoundingly:

Today and as I am writing this, Sun Microsystems is releasing Java as Free
and Open Source Software under the GPL. Simultaneously, the previously
released Glassfish project now also comes under the GPL.

And FOSS.IN is one of the first events where Sun will be showcasing all
this and more, in addition to a series of talks related to the projects.

It has been an absolute pleasure to work with Sumitha Prashanth and her
team over all these month, and they ensured that at every turn, FOSS.IN's
requirements came first - an attitude that is both rare and welcome with
big name sponsors. We, in turn welcome Java to the FOSS world, and thank
Sun for making FOSS.IN the first platform in India to mark such an
important point in the history of technology.

<end>

Now This years FOSS.in is announced. It is starting from 24th Nov to 26th Nov.
Sun Microsystems is again the plantinum sponsor for this event.
6 talks are lined up for this event from Sun.
It is scheduled on Day 2 i.e 25th Nov 2006 in A120 hall.

I am involved in the planning and preperation for this event from Sun.
Apart from Tech talks, we are also planning for lots of Technical Demos at the stall, BOFs and workshops.
This time apart from Solaris features, we have demos on Glassfish, Portal, Derby, OpenJDK, Grid engine, Belenix, Open Office, Looking Glass.

We have set a huge standards for ourselves after last years FOSS.in and this time I have support of more than 100 engineers to improve that even further.

Next few days you will read more about FOSS.in event, activities in Sun stall and talks and lots of pictures.

An interesting problem in solaris to troubleshoot

One of my colleague installed Solaris 10 U3 on a Metropolis machine. The machine was working fine for sometime.
Then it got powered off and didn't come up next time due to boot archive problem.
So she booted in failsafe session and updated the boot-archive.
Now when tried to boot in normal solaris, it boots up properly and hangs the system within a minute. Nothing works.

Myself and Shesha were trying to troubleshoot this.
Initially we thought it has something to do with Xorg. So we booted in commandline.
Even then it hunged. What frustating is everytime it hangs, reboot was the only option.
And the window where we could operate was very small. The problem was not see when we booted in single user mode.

Now we thought it has something to do with some of the services. So next time when we booted in milestone all,
the first command we executed was 'svcs -xv'. Everything looked OK.

By this time, we had already wasted almost 1 hour debugging this problem.
Even telnet, ssh was not working.
The last options at this time was to reinstall OS.
We decided to give one last try by running it under kmdb and debug the problem.

So in the grub, we gave -k option and booted the OS. When the problem was hit, we went to kmdb mode and tried to see the threadlist.
We found that there was some activity on 'acpi' module. That was the culprit. so when we disabled it while booting by specifying option
acpi-users-option=0x2.
Now that machine is working fine and my colleague is happy.

Some good words about Sun Cluster from a customer

Sun Cluster 3.2 is now in beta stage. More than 30 customer have registered to try this product.
Lot of engineers, both in Sustaining and engineering team are working with these customer to make sure
they don't have  issues when installing Sun Cluster and deploying their application on Sun Cluster.

One such customer is CuddleTech.

It is always good to hear some good words about your product from customer mouth.
Specially when customer reiterates that they got 100% uptime because of Sun Cluster, there is no better encouraging words.
Believe me it is more satisfactory than all those motivational words used by Managers. :-)

Recently Ben Rockwood blogged about his experience with Sun Cluster. The main point from his blog is

<snip>
To toss in an extra customer success story...
I deployeed my companies primary Oracle 9i database server on a pair of Sun V1280's with 2 Sun StorEdge 3510 arrays with Solaris 9 and Sun Cluster 3.0.
We deployeed the system 889 days ago. In that 2.5 years we have had 100% uptime!
 No crappy 5 9's, I'm talking 100 frickin' percent. The cluster has never even failed over.
On a handful of occasions when Oracle shutdown mistakenly Sun Cluster had the database back online before the clients even realized it.

<end>

Thanks Ben for making our day. :-)

Opensolaris is in our Head :-)

A new way evangelizing opensolaris.

1st Day in UK.

I am here in UK to attend a SVM training for a week.
I was accompanied with Vallish (my colleague) for this training.

We took United emirates flight and flew via, chennai, Dubai to London Gatwick airport.


Weather is as usual in UK. It is lazy and cloudy.
Vallish has lost his baggage. He might get it today.
We went out for shoping for him. But absolutely no crowd on street.
All the shops were closed.
We were so used to so many people. Suddenly I started missing India.

We are driving a car here. We drove from Airport to Hotel. It was Fun.
We missed a road. We came from Airport till Surrey without any problem.
Once we came out of M3, we missed a turn from A331 to A325. We went somewhere.
We saw a board saying Frimley. we just went in that direction.
Luckily we didn't go too  far. We somehow reached Frimley Green.
We had direction till Frimley Green. We wanted to go to Wharf Road.
The whole place was deserted. Absolutely no one on the streets.
We stopped at a Shell Gas station near a round about and asked for direction.
It was just 100 yards from that round about but it was on the left.

We checked into our Hotel Continental. Hotel seems to be good.
Room is spacious and neat. It also has Gym and swimming pool.
Looks to be better that Lysmoyne Hotel in which I stayed last time.
But this hotel doesn't have any newspaper.
So far I haven't figured out how to connect to net.
Lady in reception doesn't seem to have knowledge about it.

We roamed around hotel in the evening. There is a bowling alley
and a night club in the same campus. We went to night club to see how it is.
They said that it is open only on saturday from 9 pm to 2 am.

In the evening myself and Vallish went out shopping. He wanted to buy a pair of
clothes. But there was no stores near our hotel. We asked a departmental store for direction
.
He said we might get in Frimley TOwn center. SO we drove till there.
Even that place was closed. No people on the streets. Place looked deserted
Very unlikely of India, where Sunday evening all the people are on the streets shopping

We went to a Indian Restaurant Cinnomon for dinner. The food was OK. Not bad.
Tomorrow we need to reach office. God knows how we will make it.
