If you notice that EC is running low on heap size, or EC encounters an OutOfMemory error, you may need to increase the java heap size which is the working memory allocated for a JVM. Use this procedure to modify the heap settings of the Node Type.
If EC application has no defined heap size or if the default heap size setting is not suitable, use this procedure to modify the heap size setting.
For new installations, 512MB heap size is automatically set across existing EC nodes.
The "Application:<EC Application name>_<version>" page is displayed.
For more information on adding and setting heap size, see "Modify Heap Size" topic in M3 Core Administration Guide.
