If you want to get certified for MySQL Cluster then there is only one guide that you need, the MySQL 5.1 Cluster DBA Certification Study Guide. Since the move to Sun, we have changed the method that you can get the title. You can now order a ‘print-on-demand version of the guide directly from Vervante. You can go ahead and order a copy now using this link. If you think you want the book, or just want a read anyway, but don’t want to commit to buying the full guide, then you can read three of the key chapters in their entirety on docs.sun.com. You can read the chapters online here. As always, let us know what you think, whether thats about the chapters on docs.sun.com, the guide itself, or what you think of the printed Vervante guide.
