Starting NetSpool printer LUs

When you start NetSpool, the NetSpool printer LUs that are assigned to the LU classes specified on the EXEC statement in the NetSpool startup procedure are started. After NetSpool is started, you can use either (1) Infoprint Central or (2) the VTAM® VARY ACT and LUNAME ADD commands to start an LU. You might want to start an LU that is assigned to a NetSpool LU class that has not been started, or to restart an LU that you stopped.

This section describes the VTAM VARY ACT and LUNAME ADD commands. The Infoprint Central action to start a NetSpool LU is equivalent to entering both the VTAM VARY ACT and LUNAME ADD commands. For information about how to use Infoprint Central, see the Infoprint Central online help system.

Limitation: You cannot use Infoprint Central to start, stop, or display the status of NetSpool LUs if you start more than one NetSpool task. However, you can use Infoprint Central to do other functions.

Tips:

• If you specify a printer LU name in a printer definition after NetSpool is started, NetSpool automatically tries to start the LU if it is assigned to one of the LU classes that NetSpool has already started. This means that you do not need to start the LU with the NetSpool ADD command. However, you must still activate it in VTAM using either Infoprint Central or the VARY ACT command.
• After NetSpool has started, if you want to start all printers in another LU class, you can start another NetSpool task and specify the LU class on the EXEC statement. This eliminates the need to enter the LUNAME ADD command numerous times to start many printer LUs. However, if you start more than one NetSpool task, you cannot use Infoprint Central to work with NetSpool LUs.

Before you begin: The LU to be started must be defined in a printer definition in the Printer Inventory and also must be defined to VTAM with an APPL statement. For more information about APPL statements, see Creating APPL statements for NetSpool printer LUs.

Steps to start an LU with the VTAM VARY and LUNAME ADD commands:

1. If the printer LU is not active in VTAM, activate it using the VTAM VARY ACT command.

   _______________________________________________________

2. Add the printer LU to NetSpool, using the LUNAME ADD command.

   _______________________________________________________

The format of the LUNAME ADD command is:

F jobname[.id],LUNAME=lu-name,ADD

lu-name

Specifies the name of the printer LU. The name must match the LU name in a printer definition in the Printer Inventory.

If NetSpool cannot start a printer LU because it is not active in VTAM or because it has been started in another NetSpool started task, NetSpool starts the printer LU automatically at a later time, when the printer LU becomes available. If you display printer LUs using the DISPLAY command or Infoprint Central, the printer LU will be in the WAITING state.

Example: In this example, printer LU LUPRT003 is varied active in VTAM and then is added to NetSpool.

    VARY NET,ACT,ID=LUPRT003
    F jobname.id,LUNAME=LUPRT003,ADD
