When you embed the firewall in a system, you must fix the port to be used for communication, and permit communication using the fixed port only.

The following table describes the organization of this section.

Reference note
Preventing the deterioration of communication performance using connection sweeper
A firewall has a functionality to forcefully disconnect a session that has not communicated for a fixed period of time or more. A firewall is allocated between Application Server and the database server, and when the connection pool is enabled, the connections that are not used for a while might be disconnected by the firewall. There is a long waiting period for the subsequent use of the disconnected connection. You can prevent this event by specifying settings in the connection sweeper functionality to destroy the unused connections faster than the time taken by the firewall to disconnect a non-communicating session.
