Questions about MariaDB JDBC Driver
+6 Vote Up -0Vote Down
The recent release of the MariaDB client libraries has prompted questions about their purpose as well as provenance.  Colin Charles posted that some of these would be answered in the very near future.  I have a couple of specific questions about the MariaDB JDBC driver, which I hope will be addressed at that time.  
1.) What is really in the MariaDB JDBC driver and how exactly does it differ from the drizzle JDBC driver?  What, if any, relation is there to Connector/J code?  There is a

    Why Stored Programs?
    +0 Vote Up -0Vote Down

    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

    Open World 2012
    +0 Vote Up -0Vote Down

    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

    The first day of JavaOne is already over!
    Employee_Team +0 Vote Up -0Vote Down
    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),

    More GlassFish loadbalancing tips for Connector/J
    Employee +1 Vote Up -0Vote Down

    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
