Supported Versions of HP-UX

GlancePlus Pak supports HP-UX 10.20 and 11.0 in addition to HP-UX 11i.

	NOTE: VantagePoint Performance Agent for HP-UX was previously named MeasureWare Agent for HP-UX.

High Availability Monitors

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.

In this version, Event Monitoring Service (EMS) added a new state, UNAVAIL, to the package monitor. This version of HA Monitors is provided for compatibility with the change in EMS.

	NOTE: The HA Monitors product does not provide Native Language Support.

MirrorDisk/UX

Prior to HP-UX 11i, LVM mirroring supported the 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 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 is also accessible from a two-node cluster.

Compatibility Issues

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)

Process Resource Manager (PRM) Version C.01.08.02 enables system administrators to guarantee CPU, real memory, and disk bandwidth resources to users and applications on the system.

This version of PRM provides 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.

PRM 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 is controlled in the kernel, through the prm2d daemon, rather than in user space, through the prm0d daemon.

The syntax for memory records is essentially the same. The only difference being that the optional SUPPRESS field is no longer needed and is ignored if present:

#!PRM_MEM:{PRMID|GROUP}:SHARES:[CAP]:::

Also, the CAP value is treated as a hard limit to the group's memory usage. Previously, it was a soft limit that could be crossed.

The 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:

The GUI has been enhanced. PRM can be remotely managed from any system with Java Runtime Environment 1.2.2 installed. PRM has a SNMP agent that makes configuration and resource information available.

	NOTE: Process Resource Manager and HP-UX Workload Manager (see “HP-UX 11i Mission Critical Operating Environment (new)”) both make use of the PRM API. Consequently, only one of the products should be used at a time.
