Temporary Instant Capacity (TiCAP)
An HP product option included with Instant
Capacity (iCAP) that enables you to
purchase prepaid processor/core activation
rights for a specified (temporary) period of
time. Temporary capacity is sold in
increments such as 20-day or 30-day
increments, where a day equals 24 hours for
a core. TiCAP was formerly referred to as
TiCOD. See also Instant Capacity (iCAP),
Pay per use (PPU).
total CPU The maximum amount of CPU
resources (cores) on the system. With
absolute CPU units, total CPU is 100
multiplied by the number of cores. When
using relative CPU units, total CPU is 100.
Absolute CPU units are advantageous on
systems where the number of active cores
change due to Instant Capacity, Temporary
Instant Capacity, Pay per use (PPU)
(versions prior to B.05.00), or virtual
partitions. On such systems, the CPU shares
you specify remain the same amount of cores
regardless of the number of cores that are
active.
transient group A workload group that is
temporarily removed from the active WLM
configuration because it has no active SLOs
and the transient_groups keyword is set
to 1. (Workload groups associated with a
process map always remain active.)
user A user is any person using the system.
Each user has a unique name and ID,
corresponding to their login and real user ID
defined in password files (such as
/etc/passwd).
user default group The reserved workload
group OTHERS with ID 1. WLM uses this
group as the initial group for any user who
does not have a user record in the WLM
configuration file.
virtual machine A software entity
provided by HP Integrity Virtual Machines
(Integrity VM). This technology allows a
single server or nPartition to act as an
Integrity VM Host for multiple individual
virtual machines, each running its own
instance of an operating system (referred to
as a guest OS). Virtual machines are servers
in theVirtual Server Environment (VSE).
virtual partitions Also known as vPars.
HP-UX Virtual Partitions offer a unique
granularity of partitioning. For each single
core, you can create one virtual partition
running its own “instance” of the HP-UX
operating system. Complete software
isolation is provided between virtual
partitions. In addition, HP-UX Virtual
Partitions provides the ability to
dynamically move cores across virtual
partitions.
Virtual Server Environment (VSE) . An
integrated virtualization offering for HP-UX
and Linux servers. VSE provides a flexible
computing environment that maximizes
utilization of server resources. VSE consists
of a pool of dynamically sizable virtual
servers, each of which can grow and shrink
based on service-level objectives and
business priorities.
