real memory Real memory is shared by all processes. The data and instructions of any process (a program in
execution) must be available to the core by residing in real memory at the time of execution.
real user ID An integer, assigned to a user at login, that uniquely identifies the username to HP-UX.
resource manager Tool that either controls the amount of a resource that a PRM group uses or ensures applications
run in their appropriate PRM groups. Resource managers include the application manager (APPL),
the CPU manager (CPU), and the memory manager (MEM).
secure
compartment
See compartment.
Secure Resource
Partition
You form a secure resource partition by mapping a secure compartment to a PRM group. (Create
secure compartment configurations using the HP-UX feature Security Containment—or a PRM
utility such as srpgen or prm2scomp.) These partitions allow you to combine the security and
resource allocation features of Security Containment and PRM.
Available starting with HP-UX 11i v2 (B.11.23).
shares Resource allocations for CPU (for FSS PRM groups) and private memory are specified in shares.
A share is a guaranteed minimum when the system is at peak load. PRM allocates a percentage
of the system resource to each PRM group based on its number of shares relative to the sum of
it and its siblings’ number of shares.
entitlement The minimum percentage (lower limit) of CPU or memory resources guaranteed to a particular
PRM group when the total system use of these resources is at 100%.
sibling group PRM group that shares a parent group with one or more other PRM groups. Resource shares are
distributed recursively to sets of sibling groups in a hierarchy.
system
administrator
A person responsible for day-to-day system configuration and maintenance. This person has root
user capabilities.
system group The PRM group PRM_SYS with PRMID 0. PRM places all system processes in this group by default.
UID Refers to both real and effective user IDs.
user default group The PRM group OTHERS with PRMID 1. PRM uses this group as the initial group for any user who
does not have a PRM user record in the PRM configuration file.
user record Record in a PRM configuration file that specifies a user name, an initial group that the user’s
processes should run in, and optionally any alternate groups the user should be able to run
processes in.
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) accessible by the C
function getpwnam.
