A system data instance specifies a system name and the production level of your entire Pega Platform system.
All nodes in one system have a common system name, and it is recommended as a best practice that you use a distinct system name for each of the systems (such as development, test, quality-assurance, or production) in your organization.
Note: The system names prpc and IWM are reserved and should not be used.
When you create or update a rule or a data instance, the current system name is added to the History tab. When importing a ZIP archive containing a rule or data instance, this system name can be the source system on which the ZIP archive was created.
The production level affects user access to objects of specific classes, through Access of Role to Object rules.
The Data-Admin-System class contains system data instances. This class is part of the SysAdmin category.
