man page
man page. A term sometimes used in UNIX documentation for the online or hard-copy
version of a file that provides reference information. See reference page.
master. The processor providing the results to a computation, which are externalized by a
processor board.
master service processor (MSP). A service processor (SP) in HP NonStop™ S-series
servers that provides the basic service processor functions as well as centralized
system functions such as a console port, a modem port for remote support functions,
and system-load control. The enclosure containing processors 0 and 1 (group 01) also
contains a pair of MSPs. See also expansion service processor (ESP).
MB. See megabyte (MB).
MCA. Maintenance console entity.
Measure. A tool used for monitoring the performance of HP NonStop™ servers. Measure
can be used to check the performance of a ServerNet cluster.
media access control (MAC) address. A value in the Medium Access Control sublayer of
the IEEE/ISO/ANSI local area network (LAN) architecture that uniquely identifies an
individual station implementing a single point of physical attachment to a LAN.
Media Interface Connector (MIC). A type of head on a fiber-optic cable that has locking
wings on the sides.
megabyte (MB). A unit of measurement equal to 1,048,576 bytes (1024 kilobytes). See also
gigabyte (GB), kilobyte (KB), and terabyte (TB).
member. In a structured programming language, an addressable entry within a data
structure. A member can be a simple field or a data structure.
memory-exact point. A potential breakpoint location within an accelerated object file at
which the values in memory (but not necessarily the values in registers) are the same
as they would be if the object file were running in TNS interpreted mode or on a TNS
system. Most source statement boundaries are memory-exact points. Complex
statements might contain several such points: at each function call, privileged
instruction, and embedded assignment. Contrast with register-exact point and
nonexact point.
memory manager. An HP NonStop™ operating system process that implements the paging
scheme for virtual memory. This process services requests generated by different
interrupt handlers as well as by other system processes.
memory page. A unit of virtual storage. In TNS systems, a memory page contains 2048
bytes. In TNS/R systems, the page size is determined by the memory manager and
can vary, depending on the processor type.
