Specifies whether or not the IBM Session Manager TCP/IP manager is to be started as part of the IBM Session Manager startup process.
Note: The TCP parameter must be specified for TCP/IP support and if the Eclipse Server is to be used and any other relevant parameters must be actioned.
This parameter is applicable to the SYSTEM control statement (see SYSTEM statement).
TCP [Yes|No|ON|OFF]
[DISPLAY [Yes|No|ON|OFF]]
[ECLIPSEServer port-no
[DIAGS [Yes|No|ON|OFF]]]
[STN3270 port-no
[TN3270_MSG4049 [Yes|No|ON|OFF]]
[TN3270E [Yes|No|ON|OFF]]
[TN3270E_CONNECT [Yes|No|ON|OFF]]]
[IBM [IUCVname iucv-resource-id]]
[TRACE [Yes|No|ON|OFF]]
TCP YES specifies that the IBM Session Manager TCP/IP manager is to be started as part of the IBM Session Manager startup process. The manager is started at the end of IBM Session Manager startup.
Subparameters under the TCP parameter are:
This can be used if a TCP/IP error is encountered. If DISPLAY is set to YES and the error is recreated, it displays the TCP/IP control block that is in error.
ECLIPSEServer port-no
[DIAGS [Yes|No|ON|OFF]]
Specifies the port number on which the Eclipse Server listens for connection requests. TCP YES must be specified to support the Eclipse Server.
When updated the change comes into effect when the system is recycled.
The keyword under the ECLIPSESERVER subparameter is:
Additional diagnostic messages and trace output will be produced if Yes or ON is specified. This option should only be set to Yes or ON under the guidance of your local support representative.
STN3270 port-no
[TN3270_MSG4049 [Yes|No|ON|OFF]]
[TN3270E [Yes|No|ON|OFF]]
[TN3270E_CONNECT [Yes|No|ON|OFF]]
Specifies a TN3270 Server is to be started at port port-no (range 1-32767). All non-3270 TELNET users will be rejected. This subparameter must be specified if you want to use IBM Session Manager without running VTAM. If the subparameter is omitted, then the IBM Session Manager TCP manager does not start the TN3270 Server.
If you are replacing IBM's TELNET then specify port 23, and disable IBM's TELNET. Details on how to do this are contained in 'IBM Session Manager and TCP/IP' in the Installation and Customization manual.
The keywords under the STN3270 subparameter are:
TN3270_MSG4049 [Yes|No|ON|OFF]
Default: (if not specified), or TN3270_MSG4049 No or OFF is specified, is to issue message 249.
Users who access IBM Session Manager through the IBM Session Manager TN3270 Server would normally cause message 249 to be issued when they sign on. However, if TN3270_MSG4049 is specified then message 4049, containing the TN3270 Client's IP address and port, will be issued in place of message 249.
If you specify TN3270E Y then the IBM Session Manager TELNET server will negotiate with TN3270 clients to use certain TN3270E protocols.
TN3270E_CONNECT [Yes|No|ON|OFF]
If you specify TN3270E_CONNECT Y, which implies TN3270E Y, then TN3270E support is taken a step further. When TN3270E_CONNECT Y is in effect, the device name supplied by the client will be used to nominate a virtual terminal (VTAM ACB) which may be used when subsequently establishing forward sessions. For more information, refer to 'IBM Session Manager and TCP/IP' in the Installation and Customization manual.
IBM [IUCVname iucv-resource-id]
Specifies that IBM's TCP/IP product can be used.
The keyword under the IBM subparameter is:
Specifies the IUCV resource name that is to be used for TCP/IP connection.
Specifies whether an internal trace is to be performed for TCP/IP connections.
