Adding nodes to Decision Management services

Add a node to a selected Decision Management service to start that service. Add additional nodes to a selected service to scale data processing, for example, to prevent the current nodes from running out of disk space.

Note: This procedure applies only to on-premises environments.
Before you begin: Perform this procedure only for on-premises environments.
    1. Configure the environment settings specific to your application server and operating system by using the following JVM argument: java -Xmx... -DNodeType=node-type1,node-type2,node-type2 where node-type represents the Decision Management service.
      You can configure the following services:
      • ADM
      • DDS
      • RTDG
      • Stream
      • Batch
      • RealTime
      • BackgroundProcessing
      • Search
      For example:  
      java -Xmx... -DNodeType=Batch,RealTime,ADM,DDS,Stream
    2. Verify that the status of the added nodes is NORMAL.
      For more information on how to verify the status, see Monitoring Decision Management services. If the status is different than NORMAL, see Status of decision data nodes.
