HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

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 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 P9000 Performance Advisor performance is slow on
the management station. Dedicate a processor each for the HP StorageWorks P9000 Performance
Advisor Tomcat and HP StorageWorks P9000 Performance Advisor Database services. Upon restarting
the management station, the HP StorageWorks P9000 Performance Advisor Tomcat service is
considered on priority and bound to a processor followed by the Oracle process.
To improve 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 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.
P9000 Performance Advisor does not launch when the short
domain name is used
On a few occasions (example, trying to access charts saved in pdf format or reports), P9000
Performance Advisor does not launch when you use the localhost in the URL (http://<localhost>/
pa) to access P9000 Performance Advisor. In such a case, use the IP address or the fully qualified
domain name of the management station.
Workaround: Use the fully qualified domain name ([servername].[domain name]) or the IP address
of the management station in the http URL — http://<fully qualified domain name>/pa
or http://<IP_address>/pa.
To get the full qualified domain name of the management station, open the command prompt window
on your management station and execute the following command: nslookup <localhost>. The
output displayed lists the fully qualified domain name and also the IP address of your management
station.
Example:
nslookup cvxpt12
Server: resolver.hp.net
Address: 16.110.135.51
Name: cvxpt12.ind.hp.com
Address: 15.154.70.146
Where, cvxpt12 is the localhost name.
