B Special DEFINEs
Introduction
You can use Guardian DEFINEs to enable a number of NonStop AutoTMF software
optional features or to provide diagnostic and management information. Defines are
useful to test a NonStop AutoTMF software feature for a selected program, without
altering the existing configuration.
Configure NonStop AutoTMF software 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 ALTER GLOBAL on page 6-34,
ADD ATMFFILESET on page 6-6, and ADD ATMFPROGRAMS on page 6-12 for
details. If specified, a DEFINE overrides configured settings.
This appendix catalogs all DEFINEs that have some direct effect on NonStop AutoTMF
software. 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.
