Clustering equal to none might cause errors

Valid from Pega Version 7.2.2

Some Pega 7 Platform features might not work when theidentification/cluster/protocolsetting in the prconfig.xml file is set to none. Some features that might not work are remote tracing and management actions on the node from the Requestor Management and Agent Management landing pages. Setting the clustering protocol to none is not recommended and will not be supported in a future Pega 7 Platform release.

Search reindexing is automatically triggered

Valid from Pega Version 7.2.2

Reindexing on index host nodes is now triggered automatically when no other index node exists in the cluster, eliminating the need for you to manually clean up old items and start reindexing. In addition, offline index host nodes are removed as index host nodes during normal shutdown and startup of any node in the cluster. As a result, you might have to add back a node as an index host node on the Search landing page. You can configure a node to always be an index host node or to never be an index host node by using the JVM -Dindex.directory option as described in Managing Elasticsearch index host nodes outside of the Search landing page.

You can turn off automatic reindexing by using the indexing/distributed/automodecleanupandreindex Dynamic System Setting.

Node classification feature

Valid from Pega Version 7.2.2

With the node classification feature, you can group production nodes by different node types to segregate nodes by their purpose. Currently, agents and listeners can be associated with node types. If you start a node with a specific node type, the node runs only the associated agents and listeners for that node type. This enhancement improves performance and optimizes resources.

For more information, see Configuring node types for agents and listeners, Mapping listeners to node types, and Mapping agents to node types.

Default quiesce strategy changed to immediate drain

Valid from Pega Version 7.2.2

The default quiesce strategy has been changed to immediate drain, which allows you to continue to access a quiescing node to perform actions until the node is removed from the load balancer, regardless of your user role. When immediate drain is enabled, and a node is in the quiesce state, the requestor state is saved after every interaction. After the node has been removed from the load balancer, the saved state can be used to restore the requestor state on a new node in the next interaction with the server.

You can change the quiesce strategy default to slow drain by modifying the value of the session/ha/quiesce/strategy setting in the prconfig.xml file to be slowDrain.

Text analytics infrastructure upgraded to Java version 1.7

Valid from Pega Version 7.2.2

The JAR libraries that support the text analytics features of the Pega 7 Platform have been upgraded to Java 1.7. As a result of the upgrade, you can validate the Ruta scripts that contain entity extraction models and view error reports if the imported Ruta scripts are invalid. This upgrade helps you to ensure that the structure of the entity extraction models that you import to your application is always correct.

For more information, see Text Analyzer.

Visual Business Director can be used in HIPAA-regulated environments

Valid from Pega Version 7.2.2

Communication between the Visual Business Director client nodes and the Visual Business Director server nodes now uses PRCluster. This new setup allows Visual Business Director to use the underlying clustering technology instead of depending on third-party solutions.

For more information, see Visual Business Director service.

New Decision Strategy Manager alerts

Valid from Pega Version 7.2.2

Autonomic Event Services (AES) is now monitoring new Decision Strategy Manager (DSM) alerts that allow diagnosis of performance-related issues with Decisioning services (Adaptive Decision Manager, Visual Business Director, Data Flow, and Decision Data Store).

For more information, see Performance alerts, security alerts, and AES and Services landing page.

Remove obsolete versions of the PredictiveAnalytics-UI and PredictiveAnalaytics-IntSvcs rulesets

Valid from Pega Version 7.2.2

After you upgrade the Pega 7 Platform to version 7.2.2, remove the PredictiveAnalytics-UI and PredictiveAnalytics-IntSvcs rulesets from your application as their versions are obsolete. Beginning with Pega 7.2.2, use the Pega-DecisionScience ruleset that contains the latest versions of the PredictiveAnalytics-UI and PredictiveAnalytics-IntSvcs rulesets.

For more information, see About ruleset versions.

Rule creation and simulations of changes in a change request in the Decision Manager portal

Valid from Pega Version 7.2.2

Two major enhancements to revision management give Decision Manager portal users more control over change requests. Revision managers and strategy designers can now create rule instances as part of a regular change request. They also can run data flows to do simulations of changes that are introduced by the change request.

For more information, see Rule creation and simulations of changes in a change request in the Decision Manager portal.

Language detection option in Text Analyzer

Valid from Pega Version 7.2.2

On the Text Analyzer form, you can identify the language of incoming records based on their language metadata tag by selecting the Language detected by publisher option. This option applies only to Text Analyzer rules that process Twitter records. By combining this option with the advanced language filtering criteria of Twitter data sets, you can filter out unnecessary data and analyze only the Twitter records that are relevant to your business objective.

For more information, see Configuring advanced filter conditions for Twitter data and Configuring language settings.
