> I found that when the minIdle is configured then during loads, common pool creates more number of connections  it will be greater than maxActive.
> When I had following settings:
> maxActive = 50
> maxIdle = 30
> minIdle=30
> factory=org.apache.commons.dbcp.BasicDataSourceFactory
> maxWait=10000
> timeBetweenEvictionRunsMillis=900000
> numTestsPerEvictionRun=50
> minEvictableIdleTimeMillis=1800000
> testWhileIdle=true
> testOnBorrow = true
> validationQuery='select 1 from dual'
> Number of connections in the pool went upto 121. (found thru netstat)
> When I changed minIdle to 15 and did my load test connecitons in the pool went upto 66
> Looks like maxActive is getting bypassed with minIdle.
> When I changed minIdle to 10 and maxActive to 30 and maxIdle to 30 then number of connections went upto 40.
> Can someone please throw light on what is going on here? I am using DBCP 1.2.1 and common pool 1.3.
