<title>配置资源管理器(Resource Manager)</title>
|
||
<para>HornetQ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HornetQ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>hornetq-configuration.xml</literal>中(单位毫秒)。
|
||
参数<literal>transaction-timeout-scan-period</literal>定义了HornetQ扫描过期事务的间隔。</para>
|
||
<para>注意HornetQ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>
