Each Pega system has a production level, a value between 1 (lowest and least) and 5 (highest). This value affects many security features of your system.
The production levels are:
5 = production
4 = preproduction
3 = test
2 = development
1 = experimental
The System instance (the single instance of the Data-Admin-System class) contains the production level of your system. The current level is recorded as the value of the pzProductionLevel property on the Process page.
You can set this value during installation. You can change it anytime later, as described below.
A high production level number implements a restrictive security scheme for production use with few people empowered to change rules. A low number (of 1 or 2) is much less restrictive and lets developers experiment by creating and updating rules.
Production levels are referenced in Access of Role to Object rules and in various tools and wizards. In addition, through System Setting rules, you can assign distinct values for a setting based on the current production level.
To change the production level of a system, open and update the Production level field on the Production tab of the System data instance. The change takes effect (for a node) the next time that a node is started.
Ques :- What will not work anymore if I set the production level to "production" ?
Answer :- Production levels control the types of changes that are allowed and specify the purpose of the environment, for example, development or production.
Set a high production level to implement a restrictive security scheme where only few users can edit rules. Use a low production level (typically 2) for development environments where developers can create and update rules with minimal restrictions.
