Configuring for PLU Accept Using ELF
Configuring for PLU Accept Using ELF
PLU accept means allowing remote SLUs (such as SNA devices) to logon to PLU
applications on a NonStop system.
For SNAX/APN End Node using ELF, PLU accept does not require ILOGMGRs
running in IBM systems and it does not require any of the ILOGMGR and TLOGMGR
configuration required by XLF. ELF does require that SNAX/APN End Node’s Network
Node Server be either a VTAM or an Extended Border Node and that the Network
Node Server support IBM Session Services Extension (SSE).
For the CRT and ITI protocols, you must use SNAX-Creator 2 to start the NonStop
applications automatically. For the SNALU protocol, the NonStop applications must be
started explicitly.
For the SNALU protocol, no special configuration is required. For the CRT and ITI
protocols, you must SCF ADD a template LU for each and every CRT and ITI
application that will accept logon requests. You must also add an APPL object to the
Creator-2 SU for each and every CRT and ITI application that will accept logon
requests.
Template LUs
A template LU is an LU that you configure through SCF. The template LU provides the
attributes for the LUs that ELF dynamically adds when ELF receives logon requests. A
template LU differs from other LUs as follows:

Template LUs are not used for SNALU applications

Template LUs are defined only for CRT and ITI applications

Template LUs should never be opened by an application
Any LU subordinate to any PU on any line can serve as a template LU as long as that
LU meets the following configuration criteria:

The PROTOCOL specification must be CRT or ITI.

The SNANAME and DEVTYPE attributes must be specified because SCF requires
these attributes. However, the values you specify will be overlaid by values taken
from the logon request.

The CREATOR attribute must match the name specified in an APPL attribute that
defines a Creator-2 process in the SCF configuration for SNAX/APN. This Creator-
2 process subsequently launches the CRT or ITI application.

The LOCALSNANAME attribute must match the c-pluname specification of an
APPL object created as part of the SCF configuration of the Creator-2 process.
The c-pluname represents the particular CRT or ITI application to be accessed.
