mysql密码过期了,今天遇到了连接mysql,总是连接不上去,
错误现象1:
An attempt by a client to checkout a Connection has timed out
第一次出现连接超时错误,第一反应是去修改cpool.checkoutTimeout参数为18000,初始为500,结果还是错误,
在修改为36000,并且加大了c3p0连接数cpool.maxPoolSize=100
这个时候出现下面错误现象2
Connections could not be acquired from the underlying database!
一直没有定位出来,靠,突然想起,以前Oracle 11g的密码存在过期的问题,mysql会不会也有呢,试试,如何做不多写,见我的博客

修改完毕后,重启mysql和tomcat,搞定了。估计是虚拟机的原因,google了下,没有找到比较官方的说明。bitsCN.com
