Files
Customizing files are edit-format files that reside on the configuration subvolume.
You create the files and add PATHCOM commands that alter or delete configured
PATHWAY objects, add user-written components, and control user-written
components. The files and the commands that you include in them are:
CUSTCNFG
CUSTCNFG contains PATHCOM ALTER commands to alter or delete the
configuration of PATHWAY objects configured by running the definition
programs. These commands define the PATHWAY configuration before the
PATHWAY system is cool started. If you want to add TCPs, terminals, programs,
or server classes to the PATHWAY system, include the PATHCOM commands to
configure them.
CUSTCOOL
CUSTCOOL includes PATHCOM START commands to start TCPs or terminals
configured in your CUSTCNFG file. All configured servers are automatically
started by the XCOOL program.
CUSTSTOP
CUSTSTOP includes GUARDIAN 90 command interpreter STOP commands to
stop processes you configured in your CUSTCNFG file.
Each of these files is automatically invoked: CUSTCNFG by program XCNFG,
CUSTCOOL by program XCOOL, and CUSTSTOP by program XSTOP. These
programs invoke the customizing file after invoking the files generated by definition
programs.
Follow these rules for using the customizing files:
Use only CUSTCNFG as the file name for the file processed by XCNFG to alter the
PATHWAY configuration.
Use only CUSTCOOL as the file name for the file processed by XCOOL to start
user-written components you have added to the configuration.
Use only CUSTSTOP as the file name for the file processed by XSTOP to stop the
components you have added.
Ensure that CUSTCNFG and CUSTCOOL contain only PATHCOM commands.
Ensure that CUSTSTOP contains only GUARDIAN 90 command interpreter STOP
commands.
Never enter a PATHCOM EXIT command in the CUSTCNFG or CUSTCOOL files.
Ensure that CUSTCNFG, CUSTCOOL, and CUSTSTOP reside on the configuration
subvolume. The default name used by the installation procedures for the
configuration subvolume is TRANCNFG.
Specify names for user processes in CUSTCNFG; do not allow PATHWAY to give
default names to user processes. Use the same names for user processes in
CUSTSTOP that you use in CUSTCNFG.
