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

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.

2015-11-06 07:11:56,353 WARN [http-/0.0.0.0:8083-10] datasource.xa.XAResourceTransaction - XA resource 'COTXADBMS': resume for XID '31302E3235332E312E35322E746D30303030313030303939:31302E3235332E312E35322E746D31' raised -7: the XA resource has become unavailable - (Slf4jLogger.java:24)

然后我们抓住了“冻结”

…
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！
