Database Min Connection must be zero

Statement: Database Min Connection must be zero

Why?

When there is firewall between oracle database and application, firewall is timing out the connections.
The opened connections become stale connections.
Oracle / Database connection pool on app side failed to recover them and destroy.
Due to this application is getting staled connection and causing exceptions.

Due to this, it is better to have min connections zero. We can minimize the risk.
