dynamic and requires no downtime for PRM or any of the applications managed by PRM. The failed-
over application and all other existing applications on the standby system will get resources based on
shares configured in the new PRM configuration.
Integration with HP System Management Homepage
The HP System Management Homepage (HP SMH) is a web-based interface that consolidates and
simplifies single system management for HP servers on HP-UX, Linux, and Microsoft® Windows®
operating systems. By aggregating the data from HP web-based agents and management utilities, HP
SMH provides a common, easy-to-use interface for displaying hardware fault and status monitoring,
performance data, system thresholds, diagnostics, and software version control for an individual
server.
PRM, which runs only on HP-UX, provides an SMH interface so you can configure and monitor PRM
on the local system.
Integration with HP Systems Insight Manager
HP Systems Insight Manager (HP SIM) provides a single point of administration for multiple HP-UX
systems. The following PRM functionality is available through HP SIM on nodes in the cluster that have
PRM installed:
• Monitor PRM groups
• Configure PRM groups
• Display resource usage
• List resource availability
Forming Secure Resource Partitions
The HP-UX 11i v2 Security Containment feature provides process and file isolation inside secure
compartments. The combination of PRM and Security Containment, which creates Secure Resource
Partitions, is powerful. PRM by itself dedicates resources to each application instance. However, those
application instances can still interact with other processes, access files, and even interact with system
processes. When Security Containment is combined with PRM, applications can be consolidated on a
single operating system, while ensuring that any application, file, and system interaction is carefully
controlled. Using Security Containment, you can ensure that application instances cannot access
processes or files from other applications or the system unless a rule is created to specifically allow the
interaction, which ensures that multiple application instances run securely in a consolidated
environment, providing the benefits of consolidation while preserving the security of a scale-out
environment (in which each application runs by itself in an operating system instance on its own
server).
Application monitoring with HP Glanceplus
Previously, with the one-application-per-server model, resource consumption monitoring on each
system was sufficient. Resource monitoring on a per-application basis becomes much more important
as multiple applications are consolidated onto a single system.
HP Glanceplus provides a graphical display of system resource usage. Glanceplus is integrated with
PRM to provide usage information for each PRM group. Glanceplus can also be configured to
generate alarm indications if usage of a particular resource in a PRM group reaches a specified
threshold.
The alarm feature of HP Glanceplus, which is activated when a resource reaches a threshold for a
PRM group, is an excellent tool to discover and fix resource problems with applications before they
