HP XP P9000 Performance Advisor v6.0 Software Troubleshooting and FAQs Guide

Resolution
Problem:
Earlier versions of the P9000 Performance Advisor LUI required the user to set some environment
variables. This error message indicates that the classpath environment variable was not set correctly.
(This error must not occur with new install scripts.) Report this error directly to your HP contact.
Install script exits with an error
Cause
Install script exits with the message: 'JRE was not found in path <jre_location>. This is because,
the location entered for the java environment is not valid.
Resolution
In UNIX variants, execute install.sh and enter the correct path to the java environment. In
Windows, edit the JAVA_HOME environment variable, and run the install.bat script again.
Cause
Install script exits with the message: 'install.sh: this script must be run as root....exiting'. This is
because, you are not logged in as the root user.
Resolution
Log in as root, and run install.sh again.
Multiprocessor optimization
For efficient and optimized use of the management station hardware on a multi-processor or a
multi-core system, bind the HP XP P9000 Performance Advisor Tomcat and HP XP P9000
Performance Advisor Database services to individual processors. Therefore, leading to better
response load balancing and avoiding any overheads of switching, or scheduling on multiple
processors.
To enable multiprocessor optimization, you must modify the property for multiprocessor optimization
in the serverparameters.properties file. By default, multiprocessor optimization is not
enabled or switched off for HP XP P9000 Performance Advisor.
Multiprocessor optimizations #
# The following entry enables / disables the Multiprocessor Optimizations.
# Note: Valid Input = ON|OFF
Enable_MP_Optimizations=ON
You can enable this option if you find that the HP XP P9000 Performance Advisor performance is
slow on the management station. Dedicate a processor each for the HP XP P9000 Performance
Advisor Tomcat and HP XP P9000 Performance Advisor Database services. Upon restarting the
management station, the HP XP P9000 Performance Advisor Tomcat service is considered on
priority and bound to a processor followed by the Oracle process.
To improve HP XP P9000 Performance Advisor performance on a multi-processor or a multi-core
system, HP recommends enabling multiprocessor optimization as the first step. However, if you do
not see any significant performance improvement even after enabling multiprocessor optimization,
HP suggests you restore the default settings in the serverparameters.properties file and
contact HP support.
NOTE: If you set the Enable_MP_Optimizations=ON, manually change the affinity set from
the Windows Task Manager (under Processes tab, right click a process and select Set Affinity).
After restarting the management station, both the HP XP P9000 Performance Advisor performance
Tomcat and Oracle services get executed on the processor that is selected manually. This override
the property set for multiprocessor optimization in the serverparameters.properties file.
When the management station is restarted again, the value is read from
theserverparameters.properties file, and the services are run on different processors.
