     各位哥哥姐姐叔叔阿姨大婶大妈  帮我看,我项目用的是ibatis和公司自己的单点登录，系统是挂在整个公司网站上的 有自己的数据库，运行过程是：当用户点击登录链接是先从公司系统中取出用户名，然后从自己的数据库中查询看是否有该用户信息，如果有让其登录，否则拒绝。但是出现的问题是：每隔一段时间（大约15分钟），系统在点击登录链接  进入系统的时候很慢（大约登录过程需要20秒），造成的结果是可能在20秒后用户能进入系统（一直执行Connection reset，然后获得了数据库连接），也有可能是进入不了系统（原因是从数据库中获得
连接失败，在查询数据库时没查出该用户）（注：该用户有权限进入），

然后其他用户登录的时候就飞快，不会出现登录延时问题（20分钟内登录）

后台抛出的错误是：

com.ibatis.common.jdbc.exception.Nested
SQLException:

--- The error occurred while applying a parameter map.

也找了很多解决方法都不行：

具体的解决方法：（1）把连接池从simple换成jdbc到现在用的c3p0

（2）mysql 连接失效8小时改成48小时，（感觉这个没什么用，我的系统是每隔一段时候（半个小时）就开始访问慢了，当有一个人访问慢过后 后续的其他人访问就非常快了，类似与在清理垃圾）。

 ora-20003


（3）没有连接关闭的问题，用的是c3p0 不需要考虑连接关闭的。

系统需要外网能访问的，也添加了域名解析

我在本地没有任何问题（windows服务器+mysql），在测试环境（linux+mysql，没有外网功能和域名解析）也没有任何问题，就是一放到正式服务器就报这个错。

测试环境和正式环境数据库用的不是一个。正式数据库中还有其他的项目（其他项目正常），这个项目单独用一个服务器，（服务器重装linux系统和tomcat都没用）。

 ORA-01722: invalid number


没隔一段时间 它就把连接重置下 搞不明白
