SQLSERVER:Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

1、Max Pool Size 默认为100。

2、查看当前数据库连接数量,

select * from sysprocesses where dbid= db_id(‘数据库名称‘)

结果为190,

3、添加数据库查询的最大连接数量

Data Source=.;Initial Catalog=i_Master;Persist Security Info=True;User ID=NUser;Password=N2;max pool size=500设置最大连接数量 500

[bug]Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding

写在前面 在mysql中这个异常是非常常见的,超时分为连接超时和执行超时,而连接超时,大部分原因是网络问题,或客户端到服务端的端口问题造成. bug场景 有的时候,使用MySqlDataReader在读取数据的时候,datareader的特性是在在线读取,而且是一条一条往下读,也就是只进式读取.如果数据非常多,就会造成超时的问题. 这种超时是执行超时引起的. SqlCommand.CommandTimeout 获取或设置在终止执行命令的尝试并生成错误之前的等待时间. 等待命令执行的时间(以秒为单

Connection Timeout和Command Timeout

原文:Connection Timeout和Command Timeout 每次对数据库连接时,我们有时候会碰到连接超时或者命令超时,这两个超时是不一样的.以ADO.NET为例,当客户端和服务器端连接时,碰到的超时情况主要有下面几种: 当从连接池获取一个连接时,碰到超时. 当建立一个全新连接(而不是从连接池获取)时,碰到超时. 当发送一个命令(command)到SQL Server时,超时. 当发送命令(连接字符串带有"context connection=true"属性)到SQL S
