I think MariaDB has had a great few weeks recently and the timeline of these events are important.
If you are a database developer who wants to create applications using MySQL, then the MySQL for Developers course is for you. This course covers how to plan, design and implement applications using the MySQL database with realistic examples in Java and PHP.
To see more details of the content of the MySQL for Developers course, go to http://oracle.com/education/mysql and click on the Learning Paths tab and select the MySQL Developer path.

Why should you use stored programs? Great question, here’s my little insight into a situation that I heard about in a large organization.
A very large organization is having a technology argument. In someway, like politics, half-truth drives this type of discussion. This company has hundreds of databases and they’re about half SQL Server and Oracle. The argument (half-truth) states that using T-SQL or PL/SQL yields “spaghetti” code!
It seems like an old argument from my perspective. After all, I’ve been working with T-SQL and PL/SQL for a long time. Spaghetti code exists in every language when unskilled programmers solve problems but the point here is one of software architecture, and an attempt to malign stored programming in general. Let’s examine the merit of the argument against stored programs.
First of all, the argument against stored programs is simply not true. SQL DML statements, like the …
[Read more]In prior years a daily update from Open World was possible, but this year my schedule was too full to support it. This is my compendium of thoughts about MySQL Connect, JavaOne, and Open World 2012.
MySQL Connect was great – good sessions re-enforcing the positive investments Oracle is making in the product. I’ll leave to others to qualify changes in what elements of technology are opened or closed along the road to a better MySQL. The announcement of Connector/Python 1.0 GA on Saturday was great news and as a community we owe a lot to Greet Vanderkelen.
NoSQL is a hot topic along with using JSON objects and it was interesting hearing of some unequal testing paradigms to position non-Oracle solutions to be “better” …
[Read more]In the past Sunday used to be a more relaxing day with ‘just’ some JavaOne activities going on. Sunday used to be a soft day to prepare yourself for an exhausting week. This is now over as JavaOne is expanding; Sunday is now an integral part of the conference. One of the side effect of this extra day is that some activities related to JavaOne and OpenWorld such as MySQL Connect are being push to start a day earlier on Saturday (can you spot the pattern here?).
On the GlassFish front, Sunday was a very busy day! It started at the Moscone Center with the annual GlassFish Community Event where the Java EE 7 and GF 4 roadmaps were presented and discussed. During the event, different GlassFish users such as ZeroTurnaround (the JRebel guys), Grupo RBS and …
[Read more]Almost two weeks ago, I encouraged GlassFish users who need load-balanced JDBC connections to MySQL Cluster (or master-master replicated MySQL Server) to set the loadBalanceValidateConnectionOnSwapServer property to true in order to help ensure the connection chosen at re-balance is still usable. That advice triggered finding a bug (14563127) which will cause the following Exception message:
No operations allowed after connection closed. Connection closed after inability to pick valid new connection during fail-over.
If you implemented the loadBalanceValidateConnectionOnSwapServer property and are seeing the above error message, updating your driver to the newly-released 5.1.22 build will likely solve this …
[Read more]ConFoo is one of the most important web developer-oriented conferences. ConFoo 2013 will be held on February 25 through March 1 in Montreal, Canada.
We just opened call for papers and we are looking for the best PHP, Java, Ruby, DotNet,HTML5 experts who are willing to share their knowledge with the Canadian community. Candidates can submit proposals until September 23. Consult the call for papers page for details and to start submitting. That page also explains what expenses ConFoo can cover for speakers. You can also get advice on how to write proposals.
The call for papers is public, meaning that all proposals get published on the website for others to vote and comment on. This approach allows the organizers to pick subjects that have …

In late 2011 I attended a lecture by John
Wilkes on Google compute clusters, which link thousands of
commodity computers into huge task processing systems. At
this scale hardware faults are common. Google puts a lot of
effort into making failures harmless by managing hardware
efficiently and using fault-tolerant application programming
models. This is not just good for application up-time.
It also allows Google to operate on cheaper hardware with
higher failure rates, hence offers a competitive advantage in
data center operation.
It's becoming apparent we all have to think like Google to run
applications successfully in the cloud. At Continuent we run
our IT and an increasing amount of QA and development on Amazon Web Services …
Members of the MySQL Support Team wear a number of different hats here at Oracle. Obviously, our top priority is to provide amazing technical support that makes customers rave. We also have a team dedicated to processing bug reports from the MySQL Community. Some of us are active bloggers or assist on mailing lists or forums, while others find other ways to contribute to the MySQL Community. We help out with QA and product planning, write …
[Read more]The MySQL documentation section has always had this Topic Guides page containing links to the docs for the various MySQL Connectors -- the official database drivers for various languages and programming technologies. That is the most convenient way to get the information for each Connector in PDF form, rather than downloading the entire Ref Man PDF. For HTML, it was more of a shortcut, because
