HP PRM Version C.03.02.xx Release Notes for HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3

PRM Release Notes
What’s new in this version
Chapter 16
• Unix group records
You can now map existing Unix groups to PRM groups.
In the configuration file, the record has the following format:
#!UXGRP:UNIX_GROUP_NAME:{ GROUP | (NONE) }
For more information, see the prmconf(4) manpage.
You can also configure these records in the new PRM interface in SMH. For more
information, see the online help.
The prmlist command now has a -G option that displays the configured mapping of Unix
groups to PRM groups.
The prmloadconf command now creates PRM configurations with Unix group records, to
map Unix groups to PRM groups. The records created by prmloadconf map each Unix
group on the system to the placeholder “(NONE)”.
• Selective capping
Starting with HP-UX 11i v3 (B.11.31), you can limit CPU usage on a per-group basis.
For more information, see the CAP field in the group record in the prmconf(4) manpage.
For information on using this feature in PRM’s SMH interface, see the online help.
• Terminology change: ‘CPU’ to ‘core’
When referring to hardware, the term ‘core’ is now used in place of ‘CPU’ in the PRM
interfaces and documentation.
A core is the actual data-processing engine within a processor. A single processor might
have multiple cores. A core might support multiple execution threads through
Hyper-Threading.
You will still see the term ‘CPU’ when documentation refers to concepts such as CPU
resources, CPU time, CPU cycles, and the CPU scheduler.
• Extended Regular Expressions now available in alternate names
You can now use an Extended Regular Expression as the alternate name in an application
record. For more information, see the section “Pattern matching in ALTERNATE_NAME”
in the prmconf(4) manpage.
