Operating CICS from a console device

You can operate CICS® from a console device2 . In particular, you can use the console device for CICS master terminal functions, to control CICS terminals or to control several CICS regions in conjunction with multiregion operation. Normal operating-system use of the console device is not inhibited, and CICS supports multiple console devices where present.

You can invoke CICS transactions from a console device by using the MVS™ MODIFY command (F for short), and other CICS operators can communicate with the console device operator.

Note:
The CEDA transaction can be used from a console device only to INSTALL resource definitions. The sample programs cannot be executed from a console device.

To communicate with an alternate CICS region in an XRF environment, you must use the CEBT command, and issue it from a console device.

You can use TSO CLIST processing to issue sequences of CICS commands. You can also use an automated process, such as NetView, to issue CICS commands as from a console device. To associate command responses with the originating command from an automated process, you must add a command and response token (CART) to the originating command. CICS returns this CART in all write-to-operator (WTO and WTOR) macros issued in response to the command.

If you issue the MVS command d consoles, this displays a list of console devices and their names.

You can define a console device to be used for putting MODIFY commands into your job stream. For more information about putting commands into job streams, see Using JCL to initiate CICS commands.

For information about defining console devices to CICS, see the CICS System Definition Guide. For further information about defining console devices to MVS, see the z/OS MVS Initialization and Tuning Guide.

A console device can be a locally-attached system console, a TSO user defined as a console, or an automated process such as NetView®.
