Multi-master support in MySQL Connector/Java
Employee +1 Vote Up -0Vote Down

MySQL Connector/Java has long had support for replication-aware deployment, allowing a single logical Connection object to effectively “pool” connections to both a master and (potentially multiple) slaves.  This allowed scale-out of read load by distribution of read traffic to slaves, while routing write load to the master.  The JDBC specification provides a nice hook to know what’s read-only traffic – …

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 …

Load-balanced JDBC Tip for GlassFish Deployments
Employee +3 Vote Up -0Vote Down

Having supported a number of successful load-balanced JDBC applications using MySQL Cluster and MySQL Connector/J over the years, I’ve found a few problems that are unique to specific Java app servers.  A recent customer inquiry reminded me of a GlassFish-specific issue, and the Connector/J connection property we introduced to help solve it.  I thought it might be useful to document this here for any GlassFish users looking to deploy a load-balanced JDBC application with MySQL (Cluster or multi-master replication).

If you’re entirely new to the load-balancing functionality in MySQL Connector/J, you may want to …

Connector/J extension points – Load Balancing Strategies
Employee +2 Vote Up -0Vote Down

A fourth and final Connector/J extension point I covered in my JavaOne and Silicon Valley Code Camp presentations is load-balancing strategies.  This exists in order to allow you to define behavior for balancing load across multiple back-end MySQL server instances.  MySQL Connector/J’s load-balancing implementation is a simple internal connection pool.  What appears to your application as a single Connection object can actually have multiple physical connections to MySQL servers underneath (one per …
