Controlling JES2 transmitting and receiving devices

JES2 allows you to start, restart, cancel, or stop NJE device activity. All commands allow you to specify the job receivers, job transmitters, SYSOUT receivers, and SYSOUT transmitters to be acted upon.

Starting an NJE device

Use the $S L(nnnn).xx(n) command to start one or more currently drained transmitting or receiving devices. A transmitter will drain if it attempts to send a unit of work to a receiving node that has any of the following:

The corresponding receiver drained
The corresponding receiving function drained
No corresponding receiver

To activate the receiving function, the operator at the receiving end (except for case 3) should start the function ($T NODE,RECEIVE=) or receiver ($S) before the operator at the transmitting end attempts to start the transmitter.

Restarting an NJE device

Use the $E L(nnnn).xx(n) command to stop the current transmission or receipt of a job or SYSOUT data over an NJE line and requeue the data for the transmission at the appropriate node.

Controlling Work Selection on an NJE Device

You can specify the work selection characteristics of a SYSOUT transmitter by issuing the $T L(nnnn).ST(n),WS= command. Work selection can specify the size of the SYSOUT data set, in lines and pages, that is used to determine what the transmitter will select. If you are uncertain of the characteristics in effect, you can display the characteristics for a particular SYSOUT transmitter by issuing the $D L(nnnn).ST(n) command.

Canceling an NJE device

Use the $C L(nnnn).xx(n) command to cancel a job or SYSOUT data currently being received or transmitted over an NJE line.

Note: Canceling a receiver does not stop the actual transmission of data. The operator at the receiving node can elect to cancel job or SYSOUT reception by having the operator at the transmitting end cancel the transmitter.

Stopping an NJE device

Use the $P L(nnnn).xx(n) command to stop the specified NJE transmitting or receiving devices after they complete their current work. When a specified device has been drained, JES2 issues the $HASP097 device IS DRAINED message.
