For performance reasons you may need or 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 
during installation. 

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. 

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.  

The location of the file is in 
/usr/iplanet/servers/https<servername>/config/jvm12.conf

  

The maxHeapSize may need to change depending on your requirements as well. 

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.
