System configuration tools

Use the Dev Studio, Dynamic System Settings rules, and properties files and scripts, to set system-wide parameters. The specific tool depends on your situation.

System-wide security parameters

To specify system-wide security parameters, use system data instances. System data instances are occurrences of your Pega Platform. See Specifying system-wide security parameters.

Cluster-wide parameters that differ from site to site

To set cluster-wide parameters when the values differ from site to site, such as with URLs, user names, or port numbers, and when they might be set programmatically use dynamic system settings. See Dynamic system settings.

For example, you can use a dynamic system settings to configure which fields are available in full-text search. Dynamic system settings are stored in the Pega Platform database and are used by all nodes that share that database.

Individual node settings

To apply changes to only some nodes in a system, change settings in the prconfig.xml file. Settings in the prconfig.xml file apply to the node on which the prconfig.xml file resides. See Changing individual node settings by modifying the prconfig.xml file.

Production-level-specific runtime parameters

To set production-level-specific parameters, use data transforms and other rule types. Runtime system settings can differ based on a system's production level, and are further resolved at run time through rule resolution. See Configuring production-level-specific run-time settings by using system settings rules.

Application-specific configuration parameters

To set application-specific configuration parameters, use configuration definitions and configuration bundles.
