weblogic偶尔发生JDBC连接丢失
平均一天发生两次，上午一次，下午一次，发生该现象时，该应用程序异常，登陆很卡，已登陆系统的用户无法做任何操作取不到数据，但是另外一个应用节点是可以正常使用，请问应该从哪些地方排查原因！####<May 4, 2016 11:08:18 AM CST> <Error> <HTTP> <rhel6101> <AdminServer> < ExecuteThread: '16' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1462331298241> <BEA-101017> < Root cause of ServletException.
