Setting the heap size to view and collect data
To ensure optimal performance and results, the maximum number of LDEVs is restricted to 6000. To
increase the maximum number of LDEVs to 16000, increase the memory allocated to the JVM when
you start the host agent and management station services. These values must be set if you want to
view the performance of XP arrays with large number of LDEVs (64K binary (65,536)).
NOTE:
To ensure optimal performance and results, the maximum number of LDEVs for data collection is
6000. This is the total number of LDEVs across all XP arrays that are visible to a particular host agent.
You can decrease the total number of LDEVs visible to a host agent, by restricting the LDEVs that are
visible to the host. You can increase the maximum number of LDEVs visible to a host agent, by
increasing the number of LDEVs that are visible to the host. For information on increasing the number
of LDEVs that are visible to the Host Agent, see “For the management station” on page 62.
Setting the heap size for management station
To set the heap size value on a management station:
1. Copy the heap.bat file from the java_heap folder to a location of your choice on the
management station. The java_heap folder is available on the XP Performance Advisor Installation
disk 2.
2. In the command prompt, navigate to the location where you copied the heap.bat file.
3. Execute heap.bat.
4. Enter the MIN JAVA HEAP SIZE IN MBs: (For example, you can set the minimum java heap size
value to 512 MB).
5. Enter the MAX JAVA HEAP SIZE IN MBs: (For example, you can set the maximum java heap size
value to 1024 MB).
NOTE:
The minimum and maximum java heap size values that you set depends on your system's
configuration.
6. The batch file automatically stops and starts the XP Performance Advisor Tomcat services. It also
sets the specified minimum and maximum java heap size parameters in XP Performance Advisor.
