Classpath error
Cause
Unable to initialize threads: cannot find class java/lang/Thread Could not create Java VM.
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 StorageWorks P9000 Performance Advisor Tomcat and HP StorageWorks 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 P9000 Performance Advisor.
