Answer 1

可能没有什么理由：

此线程在数据库中被锁定并等待其他线程提交（或回滚）
这可能是防火墙问题。防火墙可能会处理不适当的过时连接。您可以在此处查看更多信息：http://forums.oracle.com/forums/thread.jspa?messageID=4354229

如果您正在运行存储过程，那么它显然是JDBC THIN驱动程序BUG。

将JDBC驱动程序更新为11.0.2.2。它应该修复getNextPacket问题的挂起：

可能是防火墙问题，您是否尝试检查，连接是否在数据库中处于活动状态，或者数据库是否将10Byte ping数据发送到此特定连接并且它没有问题？如果JDBC能够从Connections创建PreparedStatement，则意味着从客户端角度看Connections是正常的，但是DB和Client之间有什么关系？防火墙？路由器？检查他们的设置。
