C3P0 Connection Pool

Question

I have the following properties in my Hibernate XML to Connection Pool taken off the internet:

  <property name="hibernate.c3p0.min_size" value="4"/>
  <property name="hibernate.c3p0.max_size" value="4"/>
  <property name="hibernate.c3p0.timeout" value="300"/>
  <property name="hibernate.c3p0.max_statements" value="50"/>
  <property name="hibernate.c3p0.idle_test_period" value="3000"/>

But I have no knowledge of how to configure such properties based on my database settings.

What I must take into account to configure each of the properties?
