Should I set max pool size in database connection string? What happens if I don't?
Currently your application support 100 connections in pool. Here is what conn string will look like if you want to increase it to 200:
public static string srConnectionString = "server=localhost;database=mydb;uid=sa;pwd=mypw;Max Pool Size=200;";You can investigate how many connections with database your application use, by executing sp_who procedure in your database. In most cases default connection pool size will be enough.
"currently yes but i think it might cause problems at peak moments"I can confirm, that I had a problem where I got timeouts because of peak requests. After I set the max pool size, the application ran without any problems.IIS 7.5 / ASP.Net
For Spring yml config:
spring: datasource: url: ${DB-URL} driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver username: ${DB-USERNAME} password: ${DB-PASSWORD} hikari: auto-commit: true maximum-pool-size: 200or
application-prod.properties file:
spring.datasource.hikari.maximum-pool-size=200
