C3P0 pooled DataSources use no resources before they are actually used in a VM, and they close themselves in their finalize() method. When they are active and pooling, they may have open database connections and their pool may spawn several threads for its maintenance. You can use this method to clean these resource methods up quickly when you will no longer be using this DataSource. The resources will actually be cleaned up only if no other DataSources are sharing the same pool.
You can equivalently use the static method destroy() in the DataSources class to clean-up these resources.
This is equivalent to calling close( false ).
close
in interface PooledDataSource
DataSources.destroy(javax.sql.DataSource)
public void close(boolean force_destroy)
PooledDataSource
Should be used only with great caution. If force_destroy is set to true, this immediately destroys any pool and cleans up all resources this DataSource may be using, even if other DataSources are sharing that pool! In general, it is difficult to know whether a pool is being shared by multiple DataSources. It may depend upon whether or not a JNDI implementation returns a single instance or multiple copies upon lookup (which is undefined by the JNDI spec).
In general, this method should be used only when you wish to wind down all c3p0 pools in a ClassLoader. For example, when shutting down and restarting a web application that uses c3p0, you may wish to kill all threads making use of classes loaded by a web-app specific ClassLoader, so that the ClassLoader can be cleanly garbage collected. In this case, you may wish to use force destroy. Otherwise, it is much safer to use the simple destroy() method, which will not shut down pools that may still be in use.
To close a pool normally, use the no argument close method, or set force_destroy to false.
