  weblogic做服务器,今天进行了并发的测试性能,100的并大量,但是出现如下错误。

  (并发中调用了数据库,没调用一次建立一个连接,由于是并发环境,导致连接池资源耗尽)

个问题是数据连接池不够用了,将其设置为更大的数值(比如:100),这个问题解决。

2.第二个问题,当我数据连接池够用的情况下,出现connection reset.

    第一种可能:请求的资源(项目)性能达到了最大,导致不能处理过多的请求,连接被强制结束(客户端达到了关闭请求的条件)(服务端项目性能问题)

    第二种可能:weblogic设置了做大的连接数量(连接线程池),导致过的的请求直接被拒绝,连接重置             (weblogic配置问题)
