Setting the JRE path for a P9000 Performance Advisor UNIX host agent
While installing a P9000 Performance Advisor UNIX host agent, the installation might fail displaying
the following error:
JAVA not found
The reason might be that the Path system variable on your host is not pointing to the location where
JRE is installed.
Resolution
Configure the Path environment variable to include the JRE location:

For example, PATH=$PATH:/opt/jre1.5/bin
