TCP Receiver

The TCP Receiver process starter starts a new process when a client requests a TCP connection. When a connection request occurs, the process starter places a handle to the open connection in the connectionKey output element. This connection key can be used by subsequent activities in the process definition to read data from, write data to, or close the connection.

Field	Global Var?	Description
Name	No	The name to appear as the label for the activity in the process definition.
Description	No	Short description of the activity.
TCP Connection	No	The TCP Connection shared configuration resource that describes the port on which the local machine is listening for incoming TCP/IP requests.
Keep-Alive	No	To specify whether the TCP connections should use the keep-alive feature of sockets, select the Keep-Alive check box. Note - TCP Keep-Alive is different from HTTP Keep-Alive.

The name to appear as the label for the activity in the process definition.

Description

Short description of the activity.

TCP Connection

The TCP Connection shared configuration resource that describes the port on which the local machine is listening for incoming TCP/IP requests.

Keep-Alive

To specify whether the TCP connections should use the keep-alive feature of sockets, select the Keep-Alive check box.

Note - TCP Keep-Alive is different from HTTP Keep-Alive.

Field	Description
Sequencing Key	This field can contain an XPath expression that specifies which processes should run in order. Process instances with sequencing keys that evaluate to the same value will be executed sequentially in the order the process instance was created. See TIBCO ActiveMatrix BusinessWorks Process Design for more information about controlling the execution order of process instances and about XPath expressions.
Custom Id	This field can contain an XPath expression that specifies a custom ID for the process instance. This ID is displayed in the View Service dialog of TIBCO Administrator, and it is also available in the $_processContext process variable.

Output Item	Datatype	Description
connection	binary	The handle to the open connection. This connection can be used by subsequent activities in the process definition to specify the TCP connection to write data to, read data from, or close.
IP	string	IP address of the client sending the TCP request.
Host	string	Host name of the client sending the TCP request. This field is available only when the enableDNSLookup field in the Advanced tab of TCP Shared Connection is selected.
Port	integer	Port number of the client sending the TCP request.
