HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

• Verify the host name. Obtain the host name using the following command: nslookup
<IP_address>.
Example:
nslookup 01.01.01.01
Name: abc.ind.hp.com
<hostname>: abc
• Right click My Computer > Properties > Computer Name.
The <hostname> and the name of your system must match.
• Confirm the host name in the Oracle folder.
1. Go to <Installation_drive>\HPSS\padb\ora_db\NETWORK\ADMIN.
2. Verify the following file to confirm if HOST = <hostname>.
• listener.ora [INSTALL DIR>\HPSS\padb\ora_db\NETWORK\ADMIN\listener.ora]
• tnsnames.ora [INSTALL DIR>\HPSS\padb\ora_db\NETWORK\ADMIN\tnsnames.ora]
If HOST = <hostname>, follow these steps to modify the host name manually:
1. Click Start > Run and type services.msc in the command line.
2. Stop the HP StorageWorks XP Performance Advisor Database Listener
service.
3. Change the host name.
4. Save the text file.
5. Start the HP StorageWorks XP Performance Advisor Database Listener
service.
If the problem still persists, contact your system administrator or HP Support.
Multiprocessor optimization
For efficient and optimized use of the management station hardware on a multi-processor or a multi-core
system, you can bind the PA Tomcat (HP StorageWorks XP Performance Advisor Tomcat) and Oracle
(HP StorageWorks XP 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 XP Perf 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 XP Perf Advisor performance is slow on the management
station. Dedicate a processor each for the XP Perf Advisor Tomcat (HP StorageWorks XP Performance
Advisor Tomcat) and Oracle (HP StorageWorks XP Performance Advisor Database) services. Upon
restarting the management station, the XP Perf Advisor Tomcat process is considered on priority and
bound to a processor followed by the Oracle process.
To improve XP Perf 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.
