linux default iconBoneCP for Linux Publisher's description

BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library.....

BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library. If you are familiar with C3P0 and DBCP then you already know what this means. For the rest, this is a library that will manage a database connection for you to get faster database access in your application.


* Highly scalable, fast connection pool
* Callback (hook interceptor) mechanisms on a change of connection state.
* Partitioning capability to increase performance
* Allows direct access to a connection/statements
* Automatic resizing of pool
* Statement caching support
* Support for obtaining a connection asynchronously (by returning a Future<Connection>)
* Release helper threads to release a connection/statement in an asynchronous fashion for higher performance.
* Easy mechanism to execute a custom statement on each newly obtained connection (initSQL).
* Support to switch to a new database at runtime without shutting down an application
* Ability to replay any failed transaction automatically (for the case where database/network goes down etc)
* JMX support
* Lazy initialization capable
* Support for XML/property configuration
* Idle connection timeouts / max connection age support
* Automatic validation of connections (keep-alives etc)
* Allow obtaining of new connections via a datasource rather than via a Driver
* Datasource/Hibernate support capable
* Debugging hooks to highlight the exact place where a connection was obtained but not closed
* Debugging support to show stack locations of connections that were closed twice.
* Custom pool name support.
* Clean organised code. 100% unit test branch code coverage (over 160 JUnit tests).
* Free, open source and written in 100% pure Java with complete Javadocs.
