Tandem PLU Accept
•
An APPL must be defined as subordinate to the service manager for the SNAX
Creator-2 application
•
A local LU6.2 LU must be defined for the TLOGMGR and a remote PU and a
remote LU6.2 LU must be defined for the ILOGMGR and be subordinate to the
SNAX/APN line
•
In the IBM network, the device’s PU and LU and their supporting communication
link must have been defined and activated
•
In the IBM network, the ILOGMGR must have been defined and activated
•
The SNAX/APN line and its subordinate PUs and LUs must be started
•
The SNAX Creator-2 application must be started
Tandem PLU Accept Using ELF with End Node
Before a Tandem PLU application in this environment can accept an LU-LU session
with a terminal or workstation device in an IBM network, the following conditions must
be satisfied:
•
If SNAX/APN is connected to a Network Node server, that Network Node must
support IBM Session Services Extension (SSE)
•
The SNAX /APN service manager must be started
•
The SNAX Creator-2 application must be defined with a subordinate APPL for each
and every CRT or ITI application requiring logon from devices in the IBM network
•
An APPL must be defined, subordinate to the service manager, for the SNAX
Creator-2 application
•
A template LU must be defined as subordinate to the SNAX/APN line for each and
every CRT or ITI application requiring logon from devices in the IBM network
•
In the IBM network, the device’s PU and LU and their supporting communication
link must have been defined and activated
•
The SNAX/APN line and its subordinate PUs and LUs must be started
•
The SNAX Creator-2 application must be started
When the required conditions for XLF or ELF configuration are satisfied, the
application can be started. Figure 1-4
shows the components which enable Tandem
PLU Accept when XLF is used.
The ILOGMGR accepts logons from devices and sends program start requests to the
TLOGMGR. When the TLOGMGR receives a program start request, it creates a remote
LU to represent the requesting device and sends the program start request to the
SNAX/APN service manager. The service manager, in turn, forwards the logon
information to the SNAX Creator-2 process. The application that is subsequently
created issues an OPEN procedure call to the remote LU created by the TLOGMGR. A
subsequent data transfer operation (a WRITE, READ, or WRITEREAD procedure call)
causes SNAX/APN to send a BIND request to the device. If the BIND request produces
