Published Release Notes

Noticeable differences between work objects created in the Decision Manager portal when compared to Designer Studio

In the Decision Manager portal, you create work objects by running flows in the enterprise application that serves as the base application for the application overlay. If the enterprise application does not include the UI-Kit-7 in its application rulesets, work objects can display differently in the Decision Manager portal when compared to Designer Studio because an application overlay is always configured to include the UI-Kit-7 ruleset.

Recommendation:

1. Add the UI-Kit-7 ruleset dependency to the enterprise application.
2. Redesign the user interface to comply with the UI-Kit-7 ruleset.

Rollback functionality is limited to latest revision

The rollback functionality in DSM Revision Manager allows customers to roll back the import of the latest revision to their DSM application. Only one rollback is allowed; after a rollback, the rollback option is disabled until the next revision is imported. If importing two (or more) revisions at once then attempting a rollback, the system only rolls back one revision.

Example: a user has a base DSM application. They import Revision 1, and then import Revision 2. Next, they try to roll back both revisions. The system reverts to the Revision 1 version of the application, and the customer cannot revert all the way back to the base application.

System Management Application displaying listeners that do not require any action

After installing or upgrading to Pega 7.1.7, there is an additional available listener (Data-Decision-DNode-Service:Default) that does not require any action. This listener can be safely ignored and you should not use the System Management Application to manage any of its operations or state.

• The Data-Decision-DNode-Service:Default listener is always running on every PRPC node.
• The state of this listener is internally managed by PRPC. Starting or stopping it through SMA does not have any effect on its state.

Predictive models monitoring

In Prediction Studio, you can now monitor the predictive performance of your models to validate that they make accurate predictions. Based on that information, you can re-create or adjust the models to provide better business results, such as higher accept rates or decreased customer churn.

For more information, see Monitoring predictive models.

Kafka custom serializer

In Kafka data sets, you can now create and receive messages in your custom formats, as well as in the default JSON format. To use custom logic and formats for serializing and deserializing ClipboardPage objects, create and implement a Java class. When you create a Kafka data set, you can choose to apply JSON or your custom format that uses a PegaSerde implementation.

For more information, see Creating a Kafka data set and Kafka custom serializer/deserialized implementation.

Additional configuration options for File data sets

You can now create File data sets for more advanced scenarios by adding custom Java classes for data encryption and decryption, and by defining a file set in a manifest file.

Additionally, you can improve data management by viewing detailed information in the dedicated meta file for every file that is saved, or by automatically extending the filenames with the creation date and time.

For more information, see Creating a File data set for files on repositories and Requirements for custom stream processing in File data sets.

Simplified testing of event strategies

Evaluate event strategies by creating test runs. During each run, you can enter a number of sample events with simulated property values, such as the event time, the event key, and so on. By testing a strategy against sample data, you can understand the strategy configuration better and troubleshoot potential issues.

For more information, see Evaluate event strategies through test runs.

Data flow life cycle monitoring

You can now generate a report from the Run details section of a Data Flow rule that provides information about run events. The report includes reasons for specific events which you can analyze to troubleshoot and debug issues more quickly. You can export the report and share it with others, such as Global Customer Support.

For more information about accessing event details, see Creating a real-time run for data flows and Creating a batch run for data flows.

Data flow runs retry connections that fail

Real-time and batch data flow runs now retry dataset connections that fail when the related service is temporarily unavailable, for example, when a connection to a Cassandra database times out. With the automatic retries, you no longer need to run data-heavy and CPU-intensive jobs multiple times and the maintenance of data flow runs diminishes significantly.

For more information about accessing event details, see Creating a real-time run for data flows and Creating a batch run for data flows.

Optimized performance of decision strategies

Strategies that are part of data flows are now automatically optimized to achieve the best performance. You can also choose the properties that a strategy outputs to further increase the efficiency without additional strain on your hardware.
