Question

我创建了一个在DB中更改表的简单项目。我正在使用weblogic服务器10.3和Hibernate（hibernate-core-4.1.0.jar）进行jdbc连接。我在weblogic中创建了Datasource（oracle.jdbc.xa.client.OracleXADataSource），用于连接池。当我执行我的程序后发生错误 -

用3.6版本替换Hibernate Jars 4.1时，同一程序没有错误。当使用UCP（Oracle Universal Connection）连接池而不是DataSource时，同样的程序也在工作。使用Hibernate 4.1 jars时要做的配置是什么？

Answer 1

您已泄露连接。没关闭它。它变得不活跃，但不在池中。一段时间后，WLS注意到连接实际上是不活动的，即泄漏，并强行关闭它，将其返回池中。

使用Datasource强制释放weblogic中的非活动/收获连接
