Creating APPL statements for NetSpool printer LUs

NetSpool runs as a VTAM® application program, maintaining separate LU-LU sessions for each NetSpool printer LU. Each LU-LU session is between:

• A primary LU, which is the VTAM application that initiates the VTAM session and sends print requests
• A secondary LU, which is the NetSpool printer LU

You must create a VTAM APPL definition statement in the SYS1.VTAMLST data set for each NetSpool printer LU. Create the APPL statement in a new or existing application major node definition. Figure 6 shows two sample APPL statements under a major node named NETSPOOL.

NETSPOOL  VBUILD TYPE=APPL
*
LUPRT001  APPL  MODETAB=ISTINCLM,DLOGMOD=S3270,EAS=1,SESSLIM=YES
IMSPR002  APPL  ACBNAME=LUPRT002,MODETAB=ISTINCLM,DLOGMOD=SCS,EAS=1,SESSLIM=YES

The parameters on the APPL statement are:

statement-name

Specifies the secondary LU name used by VTAM applications to establish a VTAM session. If this name does not match the NetSpool LU name specified in the printer definition, the ACBNAME parameter must match the LU name in the printer definition. Specify one to eight alphanumeric characters. In this example, the names are: LUPRT001 and IMSPR002.

ACBNAME=lu-name

Specifies the NetSpool LU name. This name must match the LU name specified in the printer definition.

This parameter is optional. If you omit it, the default is the name specified as the statement-name.

If the LU name in the printer definition matches the statement-name, IBM® suggests that you omit the ACBNAME parameter and let it default, as shown in the first APPL statement in Figure 6.

If the LU name in the printer definition does not match the name in statement-name, which is the secondary LU name, you must specify the same LU name as in the printer definition in this parameter, as shown in the second APPL statement in Figure 6.

MODETAB=table-name

Specifies the name of a VTAM logon mode table to be used to associate each logon mode entry-name with a set of session parameters. If not specified, the default name is ISTINCLM.

DLOGMOD=entry-name

Specifies the name of an entry in the VTAM logon mode table that contains session parameters to be used when the primary LU does not provide other parameters. If this entry is used to establish the session parameters, this entry must specify correct LU type, FM profile, and TS profile parameters, as shown in Table 36. If not specified, the default is the first entry in the VTAM logon mode table specified in the MODETAB parameter.

Note:

The entry-name must be in the VTAM logon mode table named in the MODETAB parameter or in the default table named ISTINCLM.

EAS=1

Specifies the number of active sessions for this printer. Always specify 1.

SESSLIM=YES

Specify YES to allow VTAM to queue pending sessions for the secondary LU, if the secondary LU already has an active session with another primary LU.

PARSESS=NO

Specifies that multiple sessions are not allowed. PARSESS=NO is the default, so it is not shown in the example.

If the APPL statement name or the ACBNAME name is the same as the LU name of an SNA-network printer, either remove the LU definitions for the SNA-network printers or deactivate the major node containing those LU statements.
