HP StorageWorks P9000 Performance Advisor Software v5.4 Troubleshooting and FAQs Guide (T1789-96336, April 2012)

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.
Maintaining versions for host agent logs
You can maintain a minimum of three versions of the P9000 Performance Advisor host agent log file
(PerformanceAdvisorXP.log) for your reference in troubleshooting host agent issues. This is
applicable on all the supported operating platforms for P9000 Performance Advisor host agents.
In the paxp_services.properties file, specify the number of versions you want to maintain
against the Logger.NoOfFiles field. By default, a maximum of three log files are maintained.
When the log file is created, the date and time stamp of the log file gets appended to the
PerformanceAdvisorXP.log file name. Following is the file naming convention:
<yyyy-mm-dd_hh-mm-ss>_PerformanceAdvisorXP.log.
When the number of files and the specified size for each of the files have reached the maximum set
limit, the log file with the oldest date and time stamp is deleted, and a new file with the present date
and time is created.
In thepaxp_services.properties file, you can also set the minimum file size by specifying the
value for the Logger.LogFileSize field. By default, 100MB is the minimum file size. The file size
value can either be appended by MB or GB. If you choose to see the file size in GB, the minimum
file size be 1GB. If the log file size grows beyond this specified value, the data being written into the
existing log file is brought to a logical conclusion and another version of the log file is automatically
created.
NOTE:
The host agent service need not be restarted for any of the above-mentioned modifications made to
the paxp_services.properties file.
