System state data is saved for 90 days
Valid from Pega Version 7.4
System state data is now saved to the database for 90 days and can be downloaded as a JSON file. Having previous system state data available is useful for debugging system problems. Operators with the pzSystemOperationsObserver privilege can download system state data from the Cluster Management landing page for either the entire cluster or a single node. In addition, the PersistClusterState and PersistNodeState agents have been added to the Pega-RulesEngine ruleset for persisting system state data to the database.
For more information, see Downloading the system state.
PegaDATA connection settings now required in the prconfig.xml file
Valid from Pega Version 7.4
If you use the default prconfig.xml file that is included with Pega® Platform, and you have not removed the PegaDATA connection settings, no action is required. If you use a custom prconfig.xml file, for example, for running tests, ensure that the database connection settings for PegaDATA are not blank.
For more information about the connection settings, see PegaDATA connection settings in the prconfig.xml file.
Node classification replaces NodeID-based configuration
Valid from Pega Version 7.4
For simpler cluster administration and better application resiliency, Pega® Platform is moving toward a node classification model. Although agents will continue to work by using NodeIDs for several upcoming releases, use node types instead of NodeID configuration for agents, listeners, and decisioning services for more efficient operations and upgrades.
For more information, see Node classification.
