14.1. Strategy

JBossJCA uses a ManagedConnectionPool to perform the pooling. The ManagedConnectionPool is made up of subpools depending upon the strategy chosen and other pooling parameters.

xml	mbean	Internal Name	Description
	ByNothing	OnePool	A single pool of equivalent connections
<application-managed-security/>	ByApplication	PoolByCRI	Use the connection properties from allocateConnection()
<security-domain/>	ByContainer	PoolBySubject	A pool per Subject, e.g. preconfigured or EJB/Web login subjects
<security-domain-and-applicaton/>	ByContainerAndApplicaton	PoolBySubjectAndCri	A per Subject and connection property combination

Note

The xml names imply this is just about security. This is misleading.

For <security-domain-and-application/> the Subject always overrides any user/password from createConnection(user, password) in the CRI:
