连接数据库出现:Connections could not be acquired from the underlying database

通常情况下,我们连接数据库时不会有大问题,今天遇到“Connections could not be acquired from the underlying database”,大意是不能连接当前所配置的数据库。出现这种问题,一般是配置参数有误。
因为我的数据库使用的是oracle数据库,前一段时间都是没有问题的,今天出现问题,程序配置对我来说是没有变化,最近几天的访问人数没有大的增加(其实就是我一个人在访问),因此可以断定不是连接数或者配置上的问题。
问题只可能出现在数据库问题!
使用plsqld工具连接数据库,出现密码已经过期,问题终于找到!
问题解决后,特地想了想这个问题查找思路:
提示 “Connections could not be acquired from the underlying database”,可能原因:
1.数据库用户名密码是否正确;2.连接数是否超过最大连接数。
