Controlling an active BSC/NJE line *START,lname

Function

Use the *START,lname command on an active networking line to change the type of communication activity that can take place on the line and to control log tracing activity. Use the *START,lname only for BSC/NJE networking.

Syntax


>>-+-*START-+--,--lname--+-,--LOG---+--------------------------><
   '-*S-----'            +-,--NOLOG-+   
                         +-,--NORCV-+   
                         '-,--RCV---'

Parameters

lname: Specifies the name of an active networking line that directly connects your node with a remote node. JES3 modifies the activity on this line as requested in one of the following parameters.
LOG: Starts the line tracing facility for the specified line.
NOLOG: Stops the line tracing facility for the specified line and prints any data that was collected for the line.
NORCV: Prevents network jobs from being received through the specified line; network jobs can only be transmitted on this line. (You can still transmit and receive messages and commands on the line.)
RCV: Allows network jobs to be received through the specified line.

Rule

You can specify only one parameter in the command.

Results

For the NORCV parameter, JES3 does not permit the remote node on the specified line to start new transmissions to your node through the line. The remote node completes any current transmission. You can still transmit network jobs through the line and both nodes can transmit and receive messages and commands through the line.

IAT9107  DATA RECEPTION INHIBITED FOR LINE lname

For the RCV parameter JES3 notifies the remote node on the specified line to start or restart transmitting network jobs to your node through the line.

IAT9108  DATA RECEPTION PERMITTED FOR LINE lname

For the LOG parameter JES3 initiates or resumes recording status and data information in a log data set for each I/O operation on the specified line.

IAT9110  LOGGING STARTED FOR LINE lname

For the NOLOG parameter JES3 stops recording status and data information for I/O operations on the specified line and releases the spooled output to be printed. See z/OS JES3 Diagnosis for a description of the data in the log.
