我们在使用Oracle数据库的JAoss Wildfly 8.1和XA Datasource上遇到了奇怪的问题。
经过一段时间后，我们得到“无法打开连接”异常，而我们可以在池中看到100+非活动连接，但Jboss Datasource没有在池中使用任何一个但是给出异常。
以下是详细信息。

关于这个问题的任何专家意见？
答案 0 :(得分：7)
试试以下内容： 关闭pad-xid（根据https://issues.jboss.org/browse/JBTM-1249它不应该用于Oracle 11g） 打开no-tx-separate-pools（它有助于解决https://community.oracle.com/thread/3558157中提到的类似问题）
最后，当使用两个使用相同URL的Oracle xa-datasource时，我遇到了类似的问题。当我更改其中一个URL（将服务器名称更改为IP地址）时，发出“消失”。
答案 1 :(得分：0)
这对我适用于Oracle 11.2.0.1.0和WildFly 15
