Defining an APPLID for the Platform Server

You must define an APPLID for use with the platform server.

The following is an example of an APPLID definition which can be found in the APPLMFT member of the platform server SAMPLIB.

Note: For every major node defined, the VBUILD statement must be placed as the first definition statement.

Operand Description
ACBNAME Defines the Access Control Block name.

This operand also defines the minor node name for the application. ACB stands for Access Control Block.

APPC Tells VTAM that the application defined here might use the basic functions of LU6.2.

This operand is specific to VTAM.

APPLID Defines the name of the application program major node.
AUTH Defines this subsystem to have the ability to acquire an LU (ACQ), and specifies that this subsystem adheres to the methodology of VPACING to LUs (VPACE).
DLOGMOD Defines the name of the default session parameter entry that is used with this application.

The session parameters are coded in the LOGMODE entry of the MODETAB in VTAM. This mode name must also be defined on the remote system.

FUSNAPPL Defines the minor node name to the application.

The assigned name must be unique within a network. The default is FUSNAPPL, but you can choose the name as you like.

MODETAB Defines the logon mode table to be used to associate each logon mode name with a set of session parameters for the application program if the application program participates as the secondary logic unit (SLU).

VTAM searches the logon mode table for the LOGMODE that is used by the application when it participates as a SLU. This mode table contains entries that define parameters for SLUs.

PARSESS Specifies that this subsystem can have multiple sessions with other applications on an LU-LU session.

If you plan to have multiple simultaneous transfers between two LUs, you have to set this parameter to YES.

SONSCIP Tells VTAM that it can terminate sessions with the SLU on behalf of the application.
TYPE=APPL Defines to VTAM that this is a application major node definition.

No other optional operands are applicable to define an application major node. APPL is also used by default if the TYPE operand is not coded.

One APPL definition statement is required for each application that is to be identified to VTAM.

VPACING Specifies the maximum number of normal flow requests that another logical unit can send to this session before waiting to receive a pacing response.

If this value is too low, it might result in slower transfers.
