How to Modify Java Virtual Machine Memory 
For performance reasons you may want to increase the amount of memory available 
to the Java Virtual Machine on your DCA server. Note that Cisco recommends JVM 
memory never be lower than 512 Mb, the default set by the DCA is installation. 
To Change Virtual Machine memory for Windows Platform 
To change the amount of memory available to Java Virtual Machine on your DCA 
server:  
1.  Open the ServletExec Admin Tool. 
2.  In the Admin Tool navigation frame, click Virtual Machine > Settings. 
3.  In Max Heap Size, adjust the amount of available memory. 
4.  Click Submit. 
5.  Restart IIS. 
To Change Virtual Machine memory for Solaris Platform 
In the Sun ONE configuration, in the file 
/usr/iplanet/servers/https<servername>/config/jvm12.conf, uncomment the earlier 
property and place a new line for the jvm.minHeapsize to change the minHeapsize 
property.  
Example: 
#jvm.minHeapSize=1048576 
jvm.maxHeapSize=536870912
 
Likewise, you might want to change the maxHeapSize too, depending on your 
requirements. 
After changing the Virtual Machine memory file, you need to restart the Sun ONE 
server.
