Congratulations to Tien-Ming Cheng, the Fastest Informix DBA Contest 2013 Grand Prize Winner!

This year the Fastest Informix DBA Contest was held over the web so anyone, anywhere in the world could participate.The challenge was a combination of OLTP and batch. The winner was the DBA who was able to get the most transactions per minute in an OLTP benchmark while running a batch billing job at the same time that generated the most bills during a 10 minute run.

Hi, my name is Tien-Ming Cheng, and I head up a small team of DBA's for Reagola Computer Management Services in South Africa. I've been working with Informix from July 2008 and have loved every minute of it. Nowadays I mainly work around the optimization and maintenance of enterprise scale Informix systems within South Africa. I'd love to get into contact with other Informix users around the world, and see what everyone is up to.

Congratulations to all the participants and to the Honorary Fastest DBAs:
