Connection attributes in MySQL 5.6
Employee +1 Vote Up -0Vote Down

Introduced in 5.6.6, connection attributes haven’t been mentioned in any of the many overviews of new 5.6 features that I’ve seen.  You might not have even known they exist – there’s not really a “feature page” in the documentation that tells you what this is all about.  The best documentation is found in the description of the PERFORMANCE_SCHEMA tables which expose these connection attributes:

As of MySQL 5.6.6, application programs can provide key/value connection attributes to be passed to the …

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 …

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.

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 …

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 …
