SET DEFINE Command
create DEFINE names that begin with these two characters, except for specific
purposes that are described in application product documentation.
•
When an error occurs for the SET DEFINE command, no attributes or values are
changed in the working attribute set.
•
After you have set an attribute value, it persists until you reset it. You can reset an
attribute value explicitly with the RESET DEFINE command or with another SET
DEFINE command. You can reset a value implicitly by changing the CLASS
attribute.
•
If you log on from a logged-on TACL process, TACL preserves existing DEFINEs.
•
If you start a new TACL process from your existing TACL process, the new TACL
process does not inherit existing PARAM values.
•
When a backup TACL process takes over, TACL deletes existing DEFINEs.
•
The primary attribute-name value specification is the CLASS attribute, which is
specified as:
CLASS { CATALOG | DEFAULTS | MAP | SEARCH | SORT | SPOOL |
SUBSORT | TAPE }
The default is CLASS MAP. The CLASS attribute works as a DEFINE subtype,
and the seven classes have different uses:
CATALOG
makes a correlation between a logical catalog and an actual subvolume for
NonStop SQL/MP.
DEFAULTS
holds the standard default values of a process (such as the default volume).
MAP
makes a correlation between a logical device and an actual file.
SEARCH
specifies a search list of subvolumes for a program; the SEARCH class is
similar in functionality to the TACL #PMSEARCHLIST built-in variable.
SORT and SUBSORT
set parameters for FastSort processes and parallel SORTPROG processes.
SPOOL
sets parameters for the Spooler subsystem.
