My biggest shark caught late April 2011

I caught these gummy sharks while on a fishing trip late April last year(2011) and as I have been a bit away because I've been working too much, I'm posting the picture only now. The big one took me a long time to reel it in. I can say I need to visit a gym.

During the Easter holidays I had the pleasure to go fishing for 4 days.


My new Gaming PC

I’ve just put a new PC together and I’m excited about it.
Its spec is:
32GB RAM – up to 64GB RAM
AMD RADEON HD 6990 Video Card – 2 GPUs 4GB RAM
Intel i7 3960X 3.30GHz
No SSD yet. Waiting for the OCZ RevoDrive 3 X2 PCI-Express SSD price come down a bit. And then I will buy one. Imagine this on your PC: “Eliminating the SATA bottleneck, the PCIe-based Revo3 X 2 delivers ground-breaking 1.5GB/s of bandwidth and 230,000 4KB random write IOPS making this an ideal SSD for high performance applications, multimedia, and workstations.”
1.5GB/s will make PC fly.


WebSphere Application Server 6.1 on Fedora 8 using the graphical mode

How to install WebSphere Application Server 6.1 on Fedora 8 using the graphical mode, solution.

The first thing to is verify that our operating system isn’t supported officially by IBM WebSphere Application Server 6.1. You can check on that link

After downloaded or put the CD on drive, you need to extract the files from the tar.

Once you have extracted the files the first thing you want to do is run the script. If you have done that you are seeing a screen with options to install the WAS and others tools.

The deception starts when you decide to click in the link (Launch the installation wizard for WebSphere Application Server) to install WAS.

Nothing happens. You can try as many times as you want and have efforts to do it, until you get tired and annoyed then you found out that it will not work in any way.

You can keep the screen open or if you don’t like it, you are upset with the screen, just press ALT+F4 or click on “Exit” link on the screen to be more polite. I forgot you can just press CONTROL+C in the console to kill it. 🙂

To begin the installation, just move to the WAS directory. Once there try running directly the install script. Again, nothing happens. What is going on here?

Take a look on the script and close to the end of the script you will find a command line like that:

“$JAVAHOME”/bin/java –cp “$currentDir”/setup.jar –Xms256m –Xmx512 run ${PARSED_CMD_LINE} > /dev/null 2>$1

And below another line without “> /dev/null 2>$1”, so we have two options here, one is to not show what is happen by default, sending the output to /dev/null. The second one is to show the whole thing.

To go with the second execute the install script again passing the parameter “-is:javaconsole”;

$./install –is:javaconsole

The result will be:

“The installer is unable to run in graphical mode. Try running the installer with the –console or silent tag.”

That message helps a lot, or not? I don’t want to run using console or silent mode, I’ve preference for graphical mode. If we’re working by SSH or the server doesn’t have an X server installed then we need to have run the console option or configure the files to run the silent option.

Move to root directory of the installation. The type following command:

sed –i ‘s/XINERAMA/FAKEEXTN/g’ JDK/jre.pak/repository/

There is a bug in the Java JVM in all versions because of change/update in the libXibnerama. In the Java website the bug it closed. However it still happens. That error will occur for almost java applications that used GUI for installation or to run. So, this solution is applicable for all others problems related to that error, not only for WAS.

In almost of the cases you will get that error:
xcb_xlib.c:50: xcb_xlib_unlock: Assertion 'c->xlib.lock' failed

Now that you executed that command line, you are ready to install WAS.

Just run your install script again and voilà. The screen is there to you click the “Next >” buttons.

Of course, you haven’t forgotten to verify the prerequisites for the installation, before start anything, such as to install the required libraries: compat-libstdc++-33-3.2.3-61, libaio-0.3.104-2, libXp-1.0.0-8.fc8.

During the installation you will get a screen saying that your operating system isn’t supported, just click next.

Long time has passed since my last post

Yes, a long time has passed since my last post. Also a lot of things happened during that time.
I had to have an operation to remove my appendix as it got worse and I had a lot of pain, that was about 30 days away of everything to recovery.
My house that I started building on November last year(2008) is almost done and I’ll be moving in soon with my family.
I got my dissertation approved in my first try sending my Project Proposal, now I’m writing my Project Specification and once it’s finished I have to write my Project Design and then implement it and later on write the dissertation(thesis) itself.
I’m no longer working in Wellington in New Zealand since last week of January, I’ve been working here in Melbourne in different projects, actually I didn’t work during the month of February.

I was working in a project installing, configuring WebSphere Enterprise Services Bus(WESB) and developing the mediation flows using WebShere Integration Developer(WID). I’m working now with WebSphere MQ, doing consulting in throubleshoot, configuration, performance, load testing and helping the Tivoli guys to setup the Tivoli Monitoring to work with MQ monitoring. Another thing I’m working with between that time as the consulting is not a fulltime work, I’m involved in a solution definition and proof-of-concept for new coming project using WebSphere Extended Deployment(XD).

My laptop just died and had to buy a new motherboard to replace the old one, that is good story to a separated post.
I just build a new desktop, since 2004 that I had only laptops and now I decided to build a desktop again. I bought the parts separately and assembled it by myself it cost less and I can build in the way I want.
Its first setup is:
8GB Ram(up to 16GB soon);
1TB HDD(up to 5TB HDD SATA internally);
Video card EAH4850 ATI RADEON 1GB; another two will be installed further using crossfire
PCI Leadtek Winfast DTV2000H TV Tuner; – To be used with Mythtv – another one will be installed further
Motherboard Asus M4A79-DELUXE.

For today that’s it!

I’ve been busy!

Hi guys,
I’ve been busy and my blog is out-of-date. A lots of things have happened with time since my last article published here. I’m in last phase of my Master’s degree which is the dissertation/thesis, from now on I’ve 8 months to do the research and write it. Later on I’ll post more information here about my thesis, I can’t do it now as I don’t have permission and it isn’t approved yet.

Moreover, I’ve been working in some interesting project that kept me busy. I’ve to continue working in my Linux version for my PDA, Glofiish M700.
Something more, I bought a block of land in July 2008, and now I’m building my house which probably will be ready by March or April next year.
The current project I’m working is based in Wellington, New Zealand, so I’ve to commute every two weeks between Melbourne and Wellington.
In October we commemorated my son’s birthday, seven(7) years old. He is growing fast.
My wife has passed to the Level 3 on her English class, which starts next year.

While I was in New Zealand, about two weeks ago I felt another earthquake there, it lasted about 40 to 60 seconds an shook the hotel where I’m staying. The table, bed and other items shook like they were dancing or like when you live close to a train rail and the train pass very fast.

For now that is it. I hope to be back soon. I’m posting more pictures on my gallery.
