TTC_FailoverPortRange
Specifies a port range for the port that the automatic client failover thread listens on for failover notifications in an active/standby replication configuration. The failover configuration enables a client application to connect to a new active node automatically if there is a failure on the current node.
Specifying a port range helps accommodate firewalls between the client and server systems. By default, TimesTen uses a port chosen by the operating system.
See Using Automatic Client Failover in Oracle TimesTen In-Memory Database Operations Guide for more information on automatic client failover.
