在weblogic执行XA操作的时候，我们会碰到如下的错误,后来发现是JDBC配置的问题。
主要报错：
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说明transaction branch在ResourceManager端（DB, MQ等）不存在。不存在通常由两种可能：
1.transaction branch被timeout掉了，
2.就是这个branch压根就没有在ResourceManager端发起过。
对于1，可以在Weblogic的XAConnectionPool设定中Enable XA Transaction Timeout, 并对此设定一个合理的值，建议这个值比global transaction timeout大。这样weblogic在调用xaStart()的时候，会通知RM，该branch的timeout时间，而不是使用RM自己默认的timeout（对于Oracle, 默认为60秒，但一般会在120秒的时候，tx branch才会被Oracle timeout掉）。
对于2， 一般会跟配置有关系，比如两个XA datasource指向同一个XAConnectionPool, 或多个XAConnectionPool指向同一
个Database，
本例中原来的配置是只一个JDBC POOL:
单子报错如下错。
本案例中详细的报错：

解决方法,将97_Pool clone一个为Sync97_Pool是重新配置如下，问题解决：
