Online Informix DBA training for the New Year

  • Instructor-led online classes using Zoom or WebEx
  • Four days of hands-on Informixe experience
  • Each student has a separate AWS Informix server for exercises and labs
  • Q&A sessions and collaborative class discussions
  • All courses are taught by Lester Knutsen, IBM Informix Lifetime Champion, with over 40 years of Informix experience.

All training will be conducted as virtual classes. I have moved our training servers to the cloud. I continue developing and updating our course formats for a more flexible combination of instructor-led and self-paced course material with the same performance tuning benchmarks labs. I continue to offer Custom and Private Informix Courses.


We love to teach Informix

Advanced DataTools is deeply committed to offering quality training. We have trained more than 1,000 Informix database administrators, and have taught thousands of people to use business intelligence tools with our data warehouses.

Virtual Informix DBA Training

Take any scheduled course online from your desk via a web browser and an SSH client (like PuTTY). We schedule Informix DBA and Advanced Informix courses throughout the year, and other courses on demand. All courses can be customized to your requirements.

...from one of our students:

"The Advanced Performance Tuning class helped me to gain a much deeper understanding of how to analyze and troubleshoot database performance issues.The topics that we covered will also help me to make smart decisions for designing and building new databases and servers.I am very pleased with the amount of information that Lester and Art were able to pack into a 4-day course.Their depth of knowledge and experience make this class worth every penny."
