Glossary of Terms
requests in a series of log files on disk. The system manager or operator
can select which system events to record such as job/session
initiation/termination, program termination, file closing, file spooling
completion, and system shutdown. I/O device failures are recorded in the
system log and are used to detect problems before they interfere with
overall system operation.
system manager The person who manages the computer installation, responsible for
creating accounts and assigning capabilities and resource-use limits to
each user/account.
system manager capability (SM capability) A capability that allows execution of all
commands necessary to manage the system. This capability is usually only
given to a system manager, since that is the person responsible for the
structure, security, and overall operation of the system.
system master volume Any disk volume that has to be mounted for the system to boot.
This is different from nonsystem volumes, which can be removed while the
system is up and the system remains running. A system volume is always
named MPEXL_SYSTEM_MASTER.
system measurement tools (SMT) See Glance/XL.
system performance The efficiency of the system as measured by response time and
transaction throughput.
system processor unit (SPU) The chip in which all the processor boards and cards
reside.
system services control point (SSCP) A focal point within a system network
architecture (SNA) network for managing the configuration, coordinating
network operator problem requests, and providing directory support and
other session services for end users of the network.
systems network architecture (SNA) An IBM architectural model. It defines the
rules, protocols, and procedures for communication between devices within
a network.
systems programming language (SPL) A programming language for the HP 3000
Series 37 through 70 that provides control of machine instructions in a
code segment. It is used for many applications, including MPE V itself.
Most SPL programs execute in MPE/iX compatibility mode.
system startup To load the MPE operating system from either disk or tape by bringing a
subset of the MPE initiator program into memory.
system supervisor capability (OP capability) A capability assigned by the system
manager to the system supervisor's user name and account. The system
supervisor is responsible for performing backups, altering the system
configuration, and in general, tuning the computer so that it continues to
perform well and meet the needs of users.
system volume An MPE/iX system volume set. It contains a bootable system image and
system configuration on its master volume. It is the only volume needed to
load and start the system. It is always mounted and named
