Heap Space

JVM parameters that can be configured for the AppNode heap are minimum heap space (Xms) and maximum heap space (Xmx).

The default values for these parameters are -Xmx1024m -Xms128m. If you have to change this value you can update it using the BW_JAVA_OPTS environment variable.

For all the platforms the default heap size is 1024 MB, you can update it using the BW_JAVA_OPTS environment variable.

For Docker: 
docker run -e BW_JAVA_OPTS="-Xmx2048M -Xms2048M" -d -p <Host_ApplicationPortToExpose>:<Container_ApplicationPort>
<ApplicationImageName>
For Kubernetes or Pivotal Platform or Openshift: 
applications:
-name: <ApplicationName>
 memory: 512M
 path: <ArchiveName>
 buildpack: <BuildpackName>
env:
-name: BW_JAVA_OPTS
 value: "Xmx2048M -Xms2048M"
Note: To optimize memory usage at runtime, you can set the MEMORY_LIMIT environment variable to the configured memory. This variable will assign the memory to the container and it is recommended to set the minimum and maximum JVM size to the same value, 1024M
