The High Availability (HA) Monitors version A.03.20.01 product includes database monitors, disk monitors, and Management Information Base (MIB) monitors that can be used to set up notifications of changes in status for the important objects in a high availability cluster environment.
High Availability Monitors A.03.20.01 is being released for use with the HP-UX 11.0 and HP-UX 11i. This release has all the features found in earlier versions in addition to new functionality, defect repairs, and support for new hardware configurations.
This version is a minor release, with minor changes and defect fixes. The contents of HA Monitors releases A.03.00 through A.03.10 have been incorporated, together with all A.03.10 patches.
Since Event Monitoring Service (EMS) has added a new state, UNAVAIL, to the package monitor, this version of HA Monitors is provided to ensure compatibility with the change in EMS.
| |
| |
| |
| NOTE: The HA Monitors product does not provide Native Language Support. |
| |
| |
| |
The HA Monitors software requires a minimum of 4.45MB of disk space and 32MB of memory.

HP OnLineJFS 3.3 is the advanced optional product for JFS 3.3, which is the latest version of JFS, the Journaled File System. (JFS is also known as the VERITAS File System or VxFS.)
You can use the capabilities of HP OnLineJFS to perform certain key administrative tasks on mounted JFS file systems; this allows users on the system to perform their work uninterrupted. These tasks include:
Defragmenting a file system to regain performance
Resizing a file system
Creating a snapshot file system for backup purposes
See “New Version of Journaled File System (JFS)” for information about new features in JFS 3.3.
For more information on JFS 3.3 and OnLineJFS 3.3, see the following books:
HP JFS 3.3 and HP OnLineJFS 3.3 VERITAS File System 3.3 System Administrator's Guide
Managing Systems and Workgroups: A Guide for HP-UX System Administrators
Both are available on the Web at:
Prior to HP-UX 11i, Logical Volume Manager (LVM) mirroring supported the non-Shared Logical Volume Manager (non-SLVM) environment only. In other words, the disks were only accessible by a single system and could not be shared by multiple hosts.
Beginning with HP-UX 11i, LVM mirroring now automatically enables SLVM for a two-node environment supporting both non-SLVM and SLVM environments. All LVM systems can mirror their data on disk, and the mirrored copy of the data can also be accessed from a two-node cluster.
There have been no changes to the LVM command interface to enable LVM mirroring in the SLVM environment. Therefore, you must still use the lvcreate and the lvextend commands to create mirrored logical volumes. The only software code changes were made to the HP-UX kernel and do not affect any LVM manpages, or the MirrorDisk/UX version B.11.11 products, which are:
B5403BA MirrorDisk/UX License for Workstations
B2491BA MirrorDisk/UX License for Servers
To make use of the LVM mirroring capability, you may want to add extra disks to the volume group to mirror the data.
There is no need to make any changes to scripts or makefiles to make use of the LVM mirroring capability in the SLVM environment.
| |
| |
| |
| NOTE: SLVM mirroring is NOT supported for striped logical volumes and is ONLY supported in a two-node environment. SLVM mirroring does not support spared disks in a shared volume group. You should disable sparing by using the pvchange -z n <path> command on shared volume disks. |

Process Resource Manager (PRM) enables system administrators to guarantee CPU, real memory, and disk bandwidth resources to users and applications on the system.
| |
| |
| |
| NOTE: Process Resource Manager and HP-UX Workload Manager both make use of the PRM API. Consequently, only one of the products should be used at a time. (See also “HP-UX Workload Manager”.) |

HP PRM version C.02.00 provides the following:
new memory features
in-kernel memory management
dedicated memory for PRM groups
proportional overachievement for PRM groups
memory isolation - PRM uses the prm2D memory manager to optionally specify a group's memory resource to be restricted by use from other groups and processes on the system.
support for processor sets
HP PRM introduces a new type of PRM group, called a PSET PRM group, that is based on processor sets. The PSET PRM's CPU entitlement is specified by assigning it to a subset of the system's processors.
prmanalyze updated to perform new functionality
new PRM toolset for SCM
| |
| |
| |
| NOTE: Processor Sets can be installed from the December 2001 Software Pack (Optional HP-UX 11i Core Enhancements) CD included in your HP-UX 11i December 2001 media kit. You can also download Processor Sets (or order a CD from the web) from the HP Software Depot at the following web site: |

With version C.01.08.02, PRM provides the following features:
Distribution of resources through shares, hierarchical PRM groups, in-kernel memory management, a Simple Network Management Protocol (SNMP) agent, remote management of PRM, and an improved GUI.
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:
As root, go to the PRM install directory:
# cd /opt/prm/bin/
Make a backup of prm2d:
# mv prm2d prm2d.original
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.
Process Resource Manager (PRM) requires a minimum of 9MB of disk space and 2MB of memory.
