the Java heap size for a batch file:
1. Open the batch file from: <install directory>:\Program Files\Hewlett-Packard\Performance
Advisor\clui\<file.bat>
2. Replace the following line:
%javacmd% -Djava.cmd=%javacmd% -Dinstall.dir="%installdir%" -cp
%classpath% com.hp.xpsl.clui.XpPaCli %COMMAND% %*
with
%javacmd% -Djava.cmd=%javacmd% -Dinstall.dir="%installdir%" -Xms256m
-Xmx1024m -cp %classpath% com.hp.xpsl.clui.XpPaCli %COMMAND% %*

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.
