HP XP P9000 Performance Advisor Software - Manual (Page 72)

The Resize Heap tool stops the HP XP P9000 Performance Advisor Tomcat service to apply the
configured java heap size values. The service is automatically restarted once the new values are
set.
Setting the heap size values for Windows and Unix host agents
By default, the heap size value is set to Xmx1024M on a Windows or UNIX host agent. Xmx1024M
is also the maximum heap size value recommended by HP, if you are monitoring the performance
of XP and P9000 disk arrays with large number of LDEVs (64K binary (65,536)). However, increase
or decrease the heap size value based on the maximum heap size that your system supports. For
more information, refer to your operating system guide to know the maximum configurable heap
size value.
To modify the heap size value on a UNIX host agent:
1.
In the command prompt window, type cd /opt/xppa/hostagent/sbin.
2. At the prompt that appears, type ./ResizeHeapHANonWindows.sh to run the shell script
resizeheap.sh
that enables you to set the heap size values.
3. Follows steps 3 & 4 given for configuring java heap size values on a management station.
For more information, see
For the management station .
To modify the heap size value on a Windows host agent:
1.
Go to the \xppa\hostagent\JavaHeapSize folder and
double click ResizeHeapHAWindows.bat. By default, refers
