weblogic JTA 两阶段提交，JTA总是超时
运行良好的系统，从A主机移到了B主机，weblogic的JTA两阶段提交时，总是报JTA超时。

A主机环境：
HP-UX IA 11.23
Oracle 10g
weblogic 8.1SP6

B主机环境：
HP-UX IA 11.31
Oracle 10g
weblogic 8.1SP6

日志如下：
<Sep 16, 2011 6:08:49 PM GMT+08:00> <Error> <EJB> <BEA-010026> <Exception occurred during commit of transaction Name=[EJB com.bea.wlw.runtime.core.bean.SyncDispatcherBean.invoke(com.bea.wlw.runtime.core.request.Request)],Xid=BEA1-0006201D3F7EB235D7D1(519226521),Status=Rolling Back.
