Welcome to the web site of Julian Dyke.

I am an independent database consultant specialising in Oracle performance tuning and high availability including RAC and Data Guard. I am based in England and generally work for clients in the UK and Europe. I work for a number of customers, specialising in short term assignments from one day to around two months and consequently I am usually available at short notice.

I am a regular presenter at conferences and seminars in the UK, Europe and USA. A number of my recent presentations can be downloaded from this site.

I can be contacted either by e-mail info@juliandyke.com or by telephone +44 (0)7917 360777

Configuration Generator for Oracle Maximum Availability Architectures

MAAGEN is a configuration generator for Oracle Maximum Availability Architecture (MAA) configurations.

MAAGEN generates all files and scripts required to create and maintain physical standby databases. The configuration is specified in an XML document.

MAAGEN is written in Perl to allow users to implement their own customizations if required.

MAAGEN is included free with five or more days of consultancy

For more information see the MAAGEN page.

CPU Performance Tests

I have a very simple CPU performance test which I run as a sanity check on every system that I work with.

In response to overwhelming demand, I have published the results which can be found here.

Thanks to all my friends who have contributed results.
