Logon Records for
Pathway Processes
To build a logon record that points to a Pathway application, you must specify
CMDTYPE as LOGON-CHAR. You must also include the Tandem Creator process's
subdevice name within the PLUNAME operand. This name can consist of from one to
seven alphanumeric and special characters, preceded by a pound sign (#).
With both command types (LOGON-CHAR and LOGON-INIT), you have the option
of overriding the terminal protocol specified in the SCF ADD LU command. Note that
you can do this only if the protocol specified through SCF is either CRT or ITI. Also
note that you cannot override the terminal protocol through the ESS table if it has been
specified as SNALU through SCF.
For Pathway applications, specify CRT as the protocol. Note that any protocol you
specify in the ESS table record will remain in effect only for that LU-LU session.
Other optional operands that override SCF LU attributes include RECSIZE,
CHARACTERSET, SNATYPE, and CONCDATA. For a description of these
operands, see “Logon Records for Tandem TACL Processes.”
The CONCDATA Operand
(Pathway)
It is the CONCDATA operand that allows you to specify a destination PATHMON
and Pathway program. LUNS passes this information to the Tandem Creator process.
The Tandem Creator process, in turn, communicates with the specified PATHMON to
establish the LU-LU session.
The following shows what can be specified as values for the CONCDATA operand
which are passed to the Creator process. Note that you can specify only the following
Pathway parameters.
PATHWAY NAME [ \ system-name . ] $ pathmon-name
, PROGRAM pathway-application-name
[, PROCESS $ process-name ]
[, PRINTER name ]
NAME [ \ system-name . ] $ pathmon-name
specifies the name of a PATHMON. If the Pathway application resides on a
remote system, you must name the PATHMON on that remote system and
explicitly specify the system name.
This is a required parameter.
PROGRAM pathway-application-name
specifies the Pathway application program. This is a required parameter.
PROCESS process-name
specifies the name of a running process for the Pathway application to open
instead of SNAX/XF. The process specified in this parameter then opens the
SNAX/XF process. The process name must be from one to five characters long,
