18.4. Connection Factories
In Red Hat JBoss Data Grid, all JDBC cache stores rely on a
ConnectionFactory implementation to obtain a database connection. This process is also known as connection management or pooling.
A connection factory can be specified using the
ConnectionFactoryClass configuration attribute. JBoss Data Grid includes the following ConnectionFactory implementations:
- ManagedConnectionFactory
- SimpleConnectionFactory.
- PooledConnectionFactory.
18.4.1. About ManagedConnectionFactory

ManagedConnectionFactory is a connection factory that is ideal for use within managed environments such as application servers. This connection factory can explore a configured location in the JNDI tree and delegate connection management to the DataSource.
18.4.2. About SimpleConnectionFactory
Link kopierenLink in die Zwischenablage kopiert!
SimpleConnectionFactory is a connection factory that creates database connections on a per invocation basis. This connection factory is not designed for use in a production environment.
18.4.3. About PooledConnectionFactory
Link kopierenLink in die Zwischenablage kopiert!
PooledConnectionFactory is a connection factory based on C3P0, and is typically recommended for standalone deployments as opposed to deployments utilizing a servlet container, such as JBoss EAP. This connection factory functions by allowing the user to define a set of parameters which may be used for all DataSource instances generated by the factory.
