TCP_Port2, TCP_PortN

For TimesTen Classic, TimesTen uses this attribute to specify the port number to use if an automatic failover occurs. (This is unnecessary for TimesTen Scaleout.) See the description of TCP_Port for details on setting the value of this attribute and associated attributes.

The default TCP/IP port number is assumed for TCP_Port2 and TCP_PortN unless you specify a value in the appropriate TTC_ServerN connection attribute, in the ODBC connection string, or in the logical server definition. See TTC_Server or TTC_Server1 for more details.

Unspecified values for TCP_PortN inherit the value of TCP_PORT (or TCP_PORT1). For example, if TTC_Server2 is specified but TTC_Server_DSN2 and TCP_Port2 are not, then TTC_Server_DSN2 is set to the TTC_Server_DSN value and TCP_Port2 is set to the TCP_Port value.

See Using Automatic Client Failover in Oracle TimesTen In-Memory Database Operations Guide for more information on automatic client failover.

Required Privilege
