Weblogic常見故障之二：XAER_NOTA XAException問題的解決

在weblogic執行XA操作的時候，我們會碰到如下的錯誤,后來發現是JDBC配置的問題。
主要報錯：
java.sql.SQLException: XA error: XAER_NOTA : The XID is not valid start() failed on resource

'weblogic.jdbc.jta.DataSource': XAER
_NOTA : The XID is not valid

查了一下，XAER_NOTA說明transaction branch在ResourceManager端（DB, MQ等）不存在。不存在通常由兩種可能：
1.transaction branch被timeout掉了，
2.就是這個branch壓根就沒有在ResourceManager端發起過。

對於1，可以在Weblogic的XAConnectionPool設定中Enable XA Transaction Timeout, 並對此設定一個合理的值，建議這個值比global transaction timeout大。這樣weblogic在調用xaStart()的時候，會通知RM，該branch的timeout時間，而不是使用RM自己默認的timeout（對於Oracle, 默認為60秒，但一般會在120秒的時候，tx branch才會被Oracle timeout掉）。

對於2， 一般會跟配置有關系，比如兩個XA datasource指向同一個XAConnectionPool, 或多個XAConnectionPool指向同一

個Database，

本例中原來的配置是只一個JDBC POOL:

單子報錯如下錯。

本案例中詳細的報錯：

解決方法,將97_Pool clone一個為Sync97_Pool是重新配置如下，問題解決：
