12 Maintaining the Map File
115414 NonStop NET/MASTER MS System Management Guide 12–1
A map is a series of definitions, that, together, describe the structure of some item of
data. Maps are used by Mapping Services to interpret data structures used by
NonStop NET/MASTER Management Services (MS). These data structures are called
mapped data objects (MDOs).
The NonStop NET/MASTER MS map file, distributed with NonStop NET/MASTER
MS, contains map definitions for the standard maps $MAP, $MSG, $NCL, $SEC, and
$SPI. A standard map is a map supplied with NonStop NET/MASTER MS to access
data structures that are an integral part of NonStop NET/MASTER MS.
NonStop NET/MASTER MS lets you create and use maps to access data structures
that you define. These maps are called user-defined maps. You can add and delete
user-defined maps to and from the map file as required.
You can map user-defined tokens to MDOs. This adds the user-defined tokens to the
standard map $SPI. Finally, you can update the map file if the system template file is
updated.
The MDMAINT utility program, distributed with NonStop NET/MASTER MS, is
used to maintain the map file. You use the TACL RUN command to run the
MDMAINT program. This section describes how to use the MDMAINT program to
perform the following tasks:
Rebuild standard maps—either all standard maps or selected standard maps
Manage user-defined maps—that is, add and delete user-defined maps to and
from the map file
Map user-defined tokens to MDOs
Update the map file after the system template file is updated
Refer to the NonStop NET/MASTER NCL Programmer’s Guide for detailed information
on the structure and use of standard and user-defined maps.
Rebuilding Standard
Maps
The map file is copied from tape to disk during the installation of NonStop
NET/MASTER MS. The map file must exist before you can start a NonStop
NET/MASTER MS system. If you are unable to start a NonStop NET/MASTER MS
system because of a problem with the map file (perhaps the map file is corrupt) and
you cannot restore the distributed map file from a backup, you can rebuild the
standard maps in the map file by using the MDMAINT program.
You can rebuild either the whole map file or selected standard map definitions. Both
these tasks are performed using the MDMAINT program.
Note Rebuild standard maps, other than $SPI, only when directed by Tandem support personnel.
