连接集中器(事务池)。
这使得资源适配器及应用程序服务器共享资源并提供例如安全、连接池及事务处理这样的服务。
This allows the resource adapter and application server to share resources and provide services such as security, connection pooling, and transaction management.
对于托管连接池,需要进行类似的考虑:在批(及其事务)完成之前,(事务)连接将不返回到池。
A similar consideration exists with pools of managed connections: a (transactional) connection will not return to the pool until the batch (and its transaction) is completed.
