Warning! Connectivity to backend database not verified

JDBC Connection Pool 测试出现异常:

Warning! Connectivity to backend database not verified. This is either because required connection pool attributes "TestConnectionsOnReserve" or "TestConnectionsOnRelease" have not been enabled, or an invalid value has been specified for attribute "TestTableName". Please check the server log for more details

 

解决方法:weblogic的控制台中,配置pool完毕后要选择Test Reserved Connections 、 Test Released Connections选项;另外要指定测试要连接的表的名称。
