It is time to update the MySQL Cluster exam. The current exam was written when the Cluster software was at version 5.1 and 7.0.5 is available for download. Reviewing the old exam questions shows some of them are badly dated.

But updating the exam requires more than simple edits of the questions. The MySQl 5.1 Cluster DBA Certification Study Guide is the book to use for studying for the exam. And having a study guide is a vital tool for those of us who prefer to self study for an exam. Sadly, some of the authors are no longer with Sun and I am sure those still around have minimal spare cycles in their schedule.

And it would be a waste of time if the revised exam is based on a version of software that is soon to be superseded. The Cluster product has …

In the beginning, error handling in MySQL code was a straightforward process. There was your C function my_error(int nr, int MyFlags, char* format, ...)that would simply put the error on a queue for you, ready to be returned to the client at the right time. The two last arguments work just like printf. You can easily check whether the current thread threw an error by reading THD::is_error(). It is very simple and very hard to get wrong.
Later down the line, however, the need has surfaced for something more. If module A asks module B to do something as part of the execution of module A, module B might set a critical error since this would be the right thing to do had it not been part of A's execution. Then later A might call on module C to do something, but there might be code inside C that is not being executed because it notices that somewhere something went wrong and bails out.

Giuseppe Maxia writes about the availability of the active development/test ("pushbuild") MySQL binaries for users—on multiple platforms.

This is a wonderful step forward in bringing greater openness to current MySQL development and in bringing greater value to the MySQL user community!  

Every once in a while, I get to sound like a royal arse in front of a customer by saying something “I know” to be true about Pentaho that isn’t.  Usually, this is a REALLY good thing because it’s usually some limitation, or Gotcha that existed in the product that has magically disappeared with the latest release.  The danger of open source is that these things can change underneath you quickly, without any official fan fare and leave you looking like a total dolt at a customer site.  Bad for consultants like me who are constantly having to keep up with extraordinarily fast product development.  Good for customers because they get extraordinarily fast product development.

One of these experiences, which I was absolutely THRILLED to look like a dolt about, was
