Configuring the system name
If you have multiple Pega Platform systems, set a distinct system name for each system.
The system name, or system ID, identifies a single Pega Platform instance and forms part of the name of every element of that system. The system name appears on the History tab of every rule and data form that is created for or within that system. A system can have one node or a cluster of many server nodes.
The system name is the same for all nodes that belong to that system. Each node also has a unique, system-generated node ID that identifies it and that derives in part from its system ID. Do not manually edit the node IDs.
