More about the online-ticket system …

Posted by Kim on Tuesday, September 27, 2011

It’s now been two weeks, and the on-line ticket sales system is still not working as it should. All the sales kiosks in the whole country are now closed until further notice and the system is still slow, and has serious defects.

During these two weeks there has been some more information released to the public, both from the vendor (Accenture), the customer (VR) and the hosting company Tieto.

Among the more interesting ones:

A real story about an online-ticket system failing under load …

Posted by Kim on Thursday, September 15, 2011

When I read the news today, I just had to share this with the Blog – This is such a good example of when things don’t go as planned.

Today there’s been big news-flashes on several Finnish news sites about the local train monopoly firm and their new web-based ticket sales system crashing under a heavy load. They had introduced a new online ticket sales system, and where literally overrun. The official comment from the company was (translated) “we where surprised to see such traffic amounts”.

Two of the articles: here, and here

LoadRunner VuGen v9.52 on Win7 x64 – 100% Working (Updated)

Posted by Kim on Monday, April 18, 2011

I recently got Windows 7 x64 installed on my laptop, and as per information from HP LoadRunner v9.52 does NOT work with Windows 7, let alone x64 – So I got myself a Virtual Machine installed, where I have Win XP x86 for LoadRunner work.

Beeing a person who believes software should work in diverse environments, I also tried installing LoadRunner on the Win 7 machine, specifically Analysis and VuGen Read the rest of this entry »

Firebird v2.5 Alpha 1 really makes a differance

Posted by Kim on Wednesday, August 27, 2008

While on vacation I’ve been working on a pet-project that has been around for many years now. The service is a mobile device chat and is powered by Firebird and PHP.

There used to be lots of problems handling more than 400 simultaneous users, but after a DB upgrade to Firebird v2.5 Alpha 1 things really look different.

Previously the DB machine (Dualcore) had one of the CPU’s running at 100% and the other not doing much (FB was Superserver) but after the switch the TOTAL CPU now ranges between 10% and 50% on the DB machine. At the same time the WebServer CPU load also decreased and is constantly under 60% where it used to be over 95% all the time!

So by just switching to the new DB engine a tremendous performance gain was achieved! Also a lot less errors are reported to the PHP error logs. The ones still coming are a deadlocks, but around 30 / 24h which is a lot less than it used to be!

To the Firebird team I want to say “THANK YOU for making a great database engine” !
