<title>配置资源管理器Resource Manager</title>
<para>ActiveMQ有自己的资源管理器来管理JTA事务。当一个事务开始时资源管理器就得到通知并记录下该事务和它的状态。
有的时候一个事务开始后,最終被忘记。有时客户端崩溃并且再也不能恢复,这样的话该事务就一直存在下去。</para>
<para>为了解决这个问题可以配置ActiveMQ来扫描过期的事务并且将它们回滚。默认值是3000000毫秒5分钟
它表示任何超过5分钟的事务都将被删除。这个超时对应的参数是<literal
>transaction-timeout</literal>,它在配置文件<literal>activemq-configuration.xml</literal>中(单位毫秒)。
参数<literal>transaction-timeout-scan-period</literal>定义了ActiveMQ扫描过期事务的间隔。</para>
<para>注意ActiveMQ不会单方面回滚一个已经处于准备状态的XA事务。如果你认为这些事务永远不会被事务管理器transaction manager
来处理的话,你必须通过管理接口来进行回滚。</para>
