JDBC proxy that provides light-weight, transparent, fault tolerant clustering capability to any underlying JDBC driver
HA-JDBC (High-Availability JDBC) is an open source JDBC driver proxy that will allow developers to add fault tolerant, light-weight, and transparent, clustering capability to any underlying JDBC driver.

  • Supports any database accessible via JDBC.
  • High-availability/Fault Tolerance - An HA-JDBC database cluster can lose a node without failing/corrupting open transactions.
  • 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.
  • Supports full JDBC 3.0 and 4.0 feature set.
  • Out-of-the-box database-independent strategies for synchronizing a failed cluster node.
  • Exposes JMX management interface to allow administration of databases and clusters.

What's New in This Release:
  • Avoid use of PreparedStatement.addBatch(String) in SQLStateManager since not all dialects support it. Thanks to Justin Cranford.
  • Fix alter sequence SQL for Oracle dialect.
  • Fix NPE when previous coordinator is restarted. Refactor command dispatcher logic using channel that does not discard its own messages.
  • Fix MySQL restore process - replace file pipe with writing file directly to the process output.
