Special DEFINEs
Introduction
You can use Guardian DEFINEs to enable a number of AutoTMF optional features or
to provide diagnostic and management information. Defines are useful to test an
AutoTMF feature for a selected program, without altering the existing configuration.
Configure AutoTMF features using the CI commands provided when possible, because
this is easier and less error-prone than using DEFINEs. DEFINEs must be inserted in
each PATHWAY configuration and batch program execution setup; they are very easy
to omit and diagnosing a missing DEFINE is difficult.
You can configure most of these features by setting the global parameters, or for
selected files by setting a parameter of AUTOTMFFILESET, or for selected programs
by setting a parameter of AUTOTMFPROGRAMS. See
details. If specified, a DEFINE overrides configured settings.
This appendix catalogs all DEFINEs that have some direct effect on AutoTMF. Other
DEFINEs may also be used for normal application file assignments.
DEFINE Types
In many cases, the mere presence of a DEFINE will select the optional feature. Such a
DEFINE should be of class MAP and specify any legal file name; the file does not need
to exist.
In other cases, the file name of a DEFINE is an encoded message; again, the file does
not need to exist.
A third type of DEFINEs specifies actual file names for tracing and the like.
The last type of DEFINE specifies a subvolume; these should be of class CATALOG.
