title: How to decide maxIdle properties in DB connection pooling configuration?
body: <p>I am using tomcat jdbc for DB connection pooling. recently i have increased my <strong>maxActive</strong> property after frequent <strong>connection pool exhaust issue</strong> (when application under heavy load) so decided to increased the <strong>maxActive</strong> property by 50% after performing multiple load test to check the impact on CPU and memory.</p>
  <p>but i observed that there is one <strong>maxIdle</strong> property also which i haven't modified so should i increase this one also  and if yes then how to decide this number.any suggestion.</p>
