interim product modification (IPM). An interim software release that may include one or
more fixes to Tandem code or may contain code that adds function to a Tandem software
product. You receive an IPM on a BACKUP tape that contains the updated program and
documentation files in one or more distribution subvolumes (DSVs).
invalid object. A table, view, or index that is unusable because its file label is not consistent
with its catalog entries, or because it contains data that is inconsistent with a related
object or that does not satisfy constraints on the object.
invalid program. A program that requires recompilation before it can be run due to a change
made to the program or to the database.

LAN. See local area network (LAN).
LINKMON process. An operating system process that supports access to transaction-

Pathsend procedures.
local area network (LAN). A set of computers, word processors, and other electronic
devices linked to create an interoffice or inter-site network.
management applications. User-written applications that automate configuration and control
tasks. For example, a management application can request from the NonStop TS/MP
PATHMON process the same kinds of services that system managers can request
interactively using the NonStop TS/MP PATHCOM interface.
master audit trail (MAT). The audit trail that contains TMF control information and
information describing the logical ordering of audit information in all audit trails in the
system. The MAT can also store audit information generated by a set of data volumes.

systems or devices in that network can address.
Nomadic Disk Subsystem. A set of products that enables remote mirroring of NonStop
Kernel databases and the physical and logical switching of the databases between
Tandem systems. Nomadic Disk technology reduces downtime during planned system
outages and provides fast recovery from unplanned system outages.
NonStop ODBC Server. See NonStop Open Database Connectivity (ODBC) Server.
