Increase the heap space for Java-based nodes

1. To increase the heap space for an individual Java-based node, select the node on the canvas.
2. In the JvmMaxHeapSize property, specify the maximum heap size of the JVM instance that runs the node.

   On some nodes, for example the Sort node, the JvmMaxHeapSize property is displayed by default. You can find this property in the Common property group.

   If you don't see the JvmMaxHeapSize property by default, click the Properties panel menu button and select Show Hidden Properties:

   

   The default value is 2048M.

Alternatively, you can set the heap size at the server level to be inherited by all Java-based nodes, as follows:

1. Go to the "cust.prop" file located at:

   <Data360Analyze site configuration directory>/conf/cust.prop

2. Open the cust.prop file and add the following text on a new line, replacing <heap size> with the required value.

   ls.brain.node.java.javaMaxHeapSize=<heap size>

   For example:

   ls.brain.node.java.javaMaxHeapSize=2048m
