To change the amount of memory available to Java Virtual Machine on your DCA server:

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.
