Configuring a Local LU
that support SNALUXS, which is the SNAX/APN interface used in this mode of
operation. There is a slight difference in the mechanics of SNAX/APC and SNAX/HLS.
SNAX/APC is the direct target of the SNAX Creator-2 with regard to passing the
bindimage and openname. With the SNAX/HLS model, the SNAX Creator-2 will
actually open and pass the openname to the application program that uses SNAX/HLS
(Pathway) and that program will open SNAX/HLS. This means that the configuration of
SNAX Creator-2 will be different.
For further details on SNAX/HLS consult the SNAX/HLS Configuration and Control
Manual.
Configuring a Local LU
The local LU is the one that resides on the Tandem system—although it need not be on
the same Tandem node as the SNAX/APC process. It is the LU through which the local
transaction programs gain access to the SNA network.
To configure a local LU, the minimum specification requirements are:
•
Local name (LU object name) and SNA network name of the LU (SNANAME
attribute)
•
Tandem access method to be used (SNAXFILENAME attribute). If you do not
specify an access method, but just type SNAXFILENAME without a process name
it is assumed that you are requesting dynamic SNAXFILENAME support.
When the minimum requirements are specified, you also get the following defaults:
AUTOSTART NO, MAXSESSION 1 (single-session LU), DYNAMICSUPPORT NO,
SNAXMAXRETRYCOUNT 0 (no retries) and LOCAL-LU-SYNC2-SUPPORT NONE.
Optionally, you can define the following characteristics:
•
Number of sessions (single or parallel) with MAXSESSION attribute
•
Autostart capability with AUTOSTART attribute
•
The number of retries of the open to the underlying access method after an error
occurs (specified with the SNAXMAXRETRYCOUNT attribute)
•
The amount of time between each attempt to reopen the underlying SNAX access
method after an error occurs (specified with the SNAXRETRYTIMER attribute)
