MAPLOAD
MAPLOAD= map-name
loads the specified map into global memory. A map that is in memory is shown as
LOADED by the SHOW MAPS command.
A map is a set of definitions used by Mapping Services. Together, the definitions
in a map describe the entire structure of some item of data. Data described by
maps are placed in mapped data object (MDO) variables used in NCL processes.
NCL uses maps to interpret the data in these variables.
Considerations
This system parameter is not included in the display from the SHOW SYSPARMS
command or the display from the Display/Update SYSPARMS Settings option in
System Support Services.
Loading a map into memory allows NCL to use the map definitions to quickly
determine the structure of mapped data rather than accessing the map on disk
each time the map is required. This can improve the performance of NCL
processes that access the map.
Examples of maps that you should consider loading into memory are $MSG,
$NCL, and $SEC. $MSG describes the structure of data in MDO variables that
hold the responses to NonStop NET/MASTER MS commands, internally
generated event messages, and messages from EMS. $NCL describes the structure
of a record in a mapped user database (UDB). $SEC describes the structure of a
record in an MDO variable that holds a user ID definition record.
Example
The following example loads the map $SEC into memory:
SYSPARMS MAPLOAD=$SEC
