 parameter should be set between 25% and 40% of total memory. It has a default value of 128 megabytes, so this should be
 set appropriately. For example, given a database with 2GB of memory, 512MB is a recommended value.
 
+CPS and NCMP Configuration
+==========================

+JVM Memory Allocation
+
+Allocating 75% of the container's memory to the JVM heap ensures efficient memory management.
+This helps the JVM make the best use of the allocated resources while leaving enough memory for other processes.
