Using the Tandem
Creator Process
For any non-Pathway application that uses LUNS, perform the following SCF
configuration steps:
1. Define the Creator process through an ADD APPL command, specifying
APPLTYPE LUNSCRE.
2. Define the application through an ADD APPL command that also specifies the
following APPL attributes:
a. The CREATOR attribute, which must contain the name of the Tandem Creator
process
b. The APPLFILE attribute, which must contain the name of the object file where
the application can be found
For Pathway applications that use LUNS, you need only define the Tandem Creator
process. Pathway applications are not defined to LUNS through SCF ADD APPL
commands.
The Creator process can:
Be created by a high-PIN process; however, the Creator process cannot create a
high-PIN process.
Communicate with a high-PIN server.
Run at a high PIN; however, the Creator process defaults to run at a low PIN.
Recognize remote eight-character device, volume, and file names (including the $
character) .
Recognize remote six-character process names (including the $ character).
Recognize variable-length string file names.
Provide increased functionality for users who log onto a Pathway application. The
Creator process allows a user to pass along to Pathway the name of a printer that
the SCREEN COBOL program can access using the PRINT-SCREEN command.
The printer name can be a file name. If the printer is locally attached to the user’s
terminal, use the printer name IS-ATTACHED.
Startup Security Issues Any application invoked by the Creator process runs with the following process
accessor ID (PAID):
If the PROGID option in the object file is specified in the FUP SECURE command,
the application has the PAID of the owner of the object file.
If the PROGID option in the object file is not specified, the application will have
the same PAID as the Creator process.
Note If the Creator process is run with the super user ID (255,255), it is suggested that the PROGID option be
specified for any application that the Creator process starts.
