integrity
integrity. The state of a database in which stored information is consistent.
IP. See independent product (IP).
L
local transaction. A transaction that involves a requester, servers, and files that all reside
on the same system. Contrast with distributed transaction.
logical file name. The external file name that an application uses to identify a file stored on
an SMF virtual disk.
long-running transaction. A transaction that runs beyond the time specified by the
autoabort threshold or spans more than 45% of the audit trail capacity.
M
master audit trail (MAT). The audit trail that contains TMF control information (such as
commit or abort records for each transaction) and information describing the logical
ordering of audit information in all audit trails in the system. The master audit trail can
also store audit information generated by a set of data volumes. There must be
exactly one master audit trail in any TMF configuration.
Measure performance analysis subsystem. A software product used to collect
performance statistics on a wide range of system resources. With the Measure
application, you can gather data from system components, network components, and
applications. Among these elements, the Measure application allows you to obtain and
display performance statistics for TMF.
multi-threaded process. An application process that can deal with more than one TMF
transaction concurrently. A multi-threaded requester, for example, can initiate more
than one transaction concurrently and switch from one transaction to another.
Similarly, a multi-threaded server can accept multiple work requests concurrently (for
one or more transactions) and switch from one work request to another.
N
network transaction. See distributed transaction.
network-distributed transaction. See distributed transaction.
node. In the NonStop Kernel operating system environment, a node is a system that is part
of an Expand network. The name of the node, also called the system name, is the first
of four parts of the fully qualified filename. The node name is preceded by a backslash
(\); for example, \SANFRAN.
