release
With version C.01.08.02, PRM provides the following features:
• Distribution of resources through hierarchical PRM groups
• Provides a shares model of distributing resources instead of static percentages. This
model facilitates configuration changes. PRM groups can be nested, allowing for
more convenient partitioning.
• Memory controlled in the kernel, through the prm2d daemon, rather than in user
space, through the prm0d daemon.
• Syntax for memory records is essentially the same, with the only difference being
that the optional SUPPRESS field is no longer needed and is ignored if present:
#!PRM_MEM:{PRMID|GROUP}:SHARES:[CAP]:::
• CAP value is treated as a hard limit to the group’s memory usage. Previously, it was a
soft limit that could be crossed.
• prm2d in-kernel memory manager is the default for HP-UX 11i. If you prefer to use
the previous manager (prm0d), follow the steps below:
1. As root, go to the PRM install directory:
# cd /opt/prm/bin/
2. Make a backup of prm2d:
# mv prm2d prm2d.original
3. Create a symbolic link from prm2d to prm0d:
# ln -s prm0d prm2d
• Provides an enhanced GUI, which enables PRM to be remotely managed from any
system that has Java Runtime Environment 1.2.2 (or later).
• PRM has a SNMP agent that makes configuration and resource information
available.
Installation Requirements
PRM requires a minimum of 9MB of disk space (80MB if the Java Runtime Environment
is not already installed) and 2MB of memory.
Compatibility Issues
PRM can be used with GlancePlus version C.03.35.00 and later.
