Setting Java Heap Size


In some cases, you may have to increase the java heap size for the kernel:

  1.  Open launcher. properties file from /ServerKernel/etc folder.
  2.  Change the value of Kernel JVM Memory from 512MB to 1024MB (or more). (see figure below).
  3.  Save the file and restart the Kernel and WebRunner.

Please note that,

Java heap size for Kernel: 60% of the total memory
Java heap size for WebRunner: 20 % of the total memory

For Example: 
For 8GB RAM - Kernel = 4.8GB; WebRunner = 1.6GB
For 16GB RAM – Kernel = 9.6GB; WebRunner = 3.2GB
