Chapter 7 109
PSET_ATTR Passes attributes for the specified PSET to HP-UX.
(For a complete attribute list, see the -t option in the
psrset(1M) manpage.) The only attribute currently
available is the logical CPU (Hyper-Threading) feature,
available starting with HP-UX 11i v3 (B.11.31). Set
this attribute as follows:
LCPU=ON Explicitly enables Hyper-Threading
LCPU=OFF Explicitly disables Hyper-Threading
If PSET_ATTR is not specified, a
nondefault PSET inherits the
Hyper-Threading state the system
had before PRM was enabled. (The
state from before PRM was enabled is
used because PRM may change the
Hyper-Threading setting for PSET 0,
where FSS PRM groups are created,
to optimize workload performance.)
Consider the following example group/CPU records:
# PRM group records
OTHERS:1:20::
databases:HIER:30::
databases/inventory:2:10::
databases/order:3:20::
development:4:40::
mailserver:5:10::
management:PSET:::2:3,4
These group/CPU records define:
• A user default group (PRMID 1) with the name OTHERS. This group is
granted 20 CPU shares.
•Adatabases hierarchical FSS PRM group to house the inventory
and order databases.
•Aninventory FSS PRM group (PRMID 2) in the databases
hierarchy. This group is granted 10 CPU shares.
• An order processing FSS PRM group (PRMID 3) in the databases
hierarchy. This group is granted 20 CPU shares.
• An FSS PRM group development (PRMID 4) with 40 CPU shares.
