java – JBOSS：使用Atomikos在Oracle XA Transaction上冻结线程

分类：Spring作者：编程之家

当我使用atomikos和hibernate传输一些数据时,我在应用程序上的某个时间后出现错误.

它发生在连接处于活动状态的一段时间后,即使不使用这种情况也会发生.

anonyone是谁避免这个问题,修复或做一个变通方法？

最佳答案
几年前我使用weblogic作为事务管理器而不是atomikos时遇到了类似的问题.在我们的例子中,我们在oracle中有一些例外情况,其中事务已经在oracle中冻结并且忙于连接对象.

我们使用了JTA事务,我在配置文件中看到你正在使用JPA事务,但是我没有看到持久性文件(在其中你将事务类型配置为JTA)

问题与超时事务有关,具体要避免它：

You have to ensure that any transaction timeout (JTA,JPA,etc…)
is lower than the lowest value for XA transactions timeouts (like
oracle XA connections).

要实现此目的,您可以在JDBC连接池配置中分配以下内容：

XASetTransactionTimeout -> true 
XATransactionTimeout -> 0

使用XATransactionTimeout – > 0确保XA超时将是事务管理器超时

希望有帮助！
