Stopping communication on a BSC/NJE line *CANCEL,lname
Function
Use the *CANCEL,lname command to stop all communication on a networking line as soon as the current activity is complete. If you use the I parameter, communication stops immediately.
You can use this command to stop activity on a line if you want to remove the line from the network or if you want to limit activity in your system. You can also use this command to stop a transmission that is tying up a line. Use the *CANCEL,lname command only for BSC/NJE communication.
If you want to stop communication on a line for an extended period of time and you expect other nodes to continue transmitting data across the line, notify the operator at the adjacent node before stopping communication. The operator can then take action to avoid possible system problems because of a backlog of jobs at the remote node.
Parameters
- lname
- Specifies the name of a networking line. JES3 stops communication on this line.
- I
- Immediately stops communication on the specified line.
Results
- JES3 does not allow any new activity on the specified line.
- If you do not enter the I parameter, JES3 allows current activity on the specified line to complete and then sends a sign-off record to the remote node connected by this line.
- If you enter the I parameter:
- JES3 immediately stops all activity on the specified line without sending a sign-off record to the remote node connected by this line. To the remote node, it appears as if the line has stopped abnormally.
- JES3 reschedules any data transmission that was active on the specified line when you issued the command. If there is another active line to the remote node, the data is transmitted on that line. In addition, JES3 releases any spool space occupied by a data stream that has been partially received; the data is held at the sending node.
