JES2 provides networking commands ($G or “global” commands), which are those capable of being sent to any node within a network (except the node of entry). These are sent as formatted control blocks so they can be understood by any subsystem type, whereas commands sent using the $N command must be in the syntax of the target subsystem. For more information, see NJE with JES2 and Other Systems.

Global commands request that some type of action be taken for a specific job at another node. If a command is entered from a remote workstation, it will result in a “job not found” response unless the job's default print and/or punch output is for that workstation. Even a command entered from the system console will result in a “job not found” response if the job did not originate at or have default print and/or punch output for that node (unless the destination node has the sending node flagged as having network authority). (Use the $T NODE(nnnn),AUTH= command to set node command authority.)

Use the $G D display command to obtain job information for a specified job at another node. The information returned from the other node contains the job number assigned to the job by the node at which the job was first introduced to the network.

The target node for the display command must be currently connected to the network. If the node name is omitted, the command is treated as a locate command and is sent to all reachable nodes in the network and each node will respond individually to the command.

Besides displaying information about a job at another node, you may hold and release a job, cancel a job, or request another node to route job output or to route a job for execution. For information about using these commands, see “Controlling Jobs at Another Node” in “ Controlling Jobs and Output”.
