HA-JDBC

HA-JDBC is a JDBC driver proxy that provides light-weight, transparent, fault tolerant clustering capability to any underlying JDBC driver. Features * Supports any database accessible via JDBC. * 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 database clusters.
