HA-JDBC is a JDBC driver proxy that provides light-weight, transparent, fault tolerant clustering capability to any underlying JDBC driver.
Features

* High-availability/Fault Tolerance - An HA-JDBC database cluster can lose a node without failing/corrupting the current transaction.
* Live activation/deactivation allows for maintenance/upgrading of a database node without loss of service.
* Improves performance of concurrent read-access by distributing load across individual nodes.
* Support for full JDBC 3.0 (Java 1.4) feature set.
* Compatible with JDBC RowSet implementations found in Java 1.5.
* Out-of-the-box database-independent strategies for synchronizing a failed cluster node.
* Exposes JMX management interface to allow administration of databases and clusters.
* Ability to add database nodes to a cluster at runtime.
* Can be scheduled to auto-activate failed database nodes at off-peak times.
* Open source (LGPL)."
