Published Release Notes

Improved indexing performance by gradual retrieval of data

Search functionality in Pega Platform™ versions from 8.4.5 to 8.6 now includes the option to improve indexing performance when reading query results from a large table in a database. For example, to load the recommended 50 records at a time, in the Pega-SearchEngine ruleset, create the indexing/distributed/fetchsize dynamic system setting, and set the value to 50.

Creating the fetchsize dynamic system setting ensures that your system does not crash while indexing classes with numerous instances.

For more information, see Creating a dynamic system setting.

Case outcome predictions in case types

Pega Platform™ introduces the use of machine learning and AI in Case Designer. You can now use predictions in case types, both in App Studio and Dev Studio. By using predictions, your application can predict various outcomes, such as the possibility of reaching a positive or negative case resolution, so that you can prioritize work, route cases according to risk, or optimize the case flow in other ways. You can use predictions when you create conditions in the condition builder, for example, when you define a business logic for routing assignments.

• Prioritize and route case work by predicting case outcomes 
• Predicting case outcome
• Creating predictions for case management

Virtual questions deprecated in 8.6

Following the improvements in Pega Intelligent Virtual Assistant (IVA), the creation of virtual questions is now deprecated and planned for removal. To avoid additional effort during updates to future releases, do not use deprecated features. For optimal application performance and efficient development of conversation processes, you now collect information from users by using the Ask a question smart shape.

For more information, see Adding a case type conversation process for a conversational channel and Asking a question in a case.

Data model inheritance does not depend on ruleset context

Search and Reporting Service (SRS) in Pega Platform™ 8.6 now provides an improved method of synchronizing data model by distinct users. In applications built on earlier versions of Pega Platform, some users might encounter difficulties in indexing data. Now, the data model that the system sends to SRS does not depend on access privileges. With this enhancement, each user of your application is eligible to synchronize data.

Post files and links with pxPostMessage API

The pxPostMessageAPI now supports text messages, file attachments, and hyperlinks. You can programmatically update Pulse streams using this API from activities or SLA rules.

Case Management

This release has continued to focus on improving the functionality of the design environment with improvements to the Case Designer and stage configuration. Additional end user capabilities were also added to allow for processing a wider variety of cases, for those with and without stages and improved bulk processing handling.

• Flow action processing now uses the primary page instead of the interest page when using case/stage local actions, so that embedded flows are properly populated.
• Case-wide local actions rely on pzInternalStageFlow when there are no active, non-hidden assignments on the case. These case-wide local actions will now appear on a stage-less flow with no assignments.
• If a (valid) error is displayed in the outline view, saving or clicking around will not delete the error - the error will remain as a reminder to the developer to solve whatever problem is being flagged.
• May now add Cascading Approval validation and edit the parameters from the Case Designer Stage and Step page.
• Page labelling ("Page 1 of X") appears in the history list presented in the audit tab.
• The bulk processing feature has been enhanced.
• The Outline View functionality was changed so that the visible page will no longer refresh each time a flow is edited.
• The Post value was added to the instructions text field, so data isn't lost between nodes in the outline View.
• When Assign to Operator or workbasket is included as a filter, the bulk processing gadget is supposed to get a list of assignments. The UI for the results was enhanced for assignments to include a column for instructions so that the different assignments on the same work item can be distinguished.
• When designing a case type’s stages, it is no longer possible to skip the last stage (by using the "skip stage when" setting). When creating or editing the last stage, developers may no longer set a skip when rule; if tried, the system will display a warning and prevent that. If a Skip When rule is set up for a stage, and then all the intervening stages are deleted so that this stage becomes the last stage, the warning will display, and the Skip When rule will not be visible. If another stage is then added after that, the Skip When rule becomes visible again.
• When one or more locked work objects are processed using the Process Selected Items button, the action will be performed on the selected work objects. If the action is successful, a green tick appears on the work object. If it is not successful, a red cross will appear.
• When the topmost RuleSet in the RuleSet Stack is locked, customers may now open up Outline View by clicking "Configure Process Details" and make exploratory changes to experiment. Because the RuleSet is locked, these changes may not be saved, but the experiment can be tried.

Flow rules not supported in IE8

In versions prior to 7.1.2, flow rules do not open in Internet Explorer 8 (IE8). Upgrade your system to the latest version of PRPC or access flows from another supported browser.

Quickly create ad-hoc cases

The My Cases work area on the Case Manager portal introduces a Quick Create feature that lets users create cases and assign tasks that are not included in the processing of business cases (instances of case types defined in the Cases Explorer).  For example, a manager can create a case and a task to set up a phone conference with her staff, or a reminder to enroll in an online seminar. Users can also set up a series of tasks to represent all they work they need to do to accomplish a specific goal.

Tomcat log files moved to work directory

For Tomcat application server users, the default path for PRPC logs has been changed to the "work" directory for Catalina. For example:

<tomcat>\work\Catalina\localhost\prweb

This directory can be cleaned up during administration. To avoid loss of files, you can redirect logging to a different directory after installation:

1. Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
2. Open the prlogging.xml file.
3. Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
4. Update the FileNamePattern values to point to the new directory.

For more details, refer to the “Change the default path to PRPC logs” section in the Tomcat installation guide for your database.

Supported JDBC drivers

Pega 7.1.1 supports Java 6 and Java 7 SDKs only. Ensure that the JDBC driver you are using supports those versions of Java. See your database installation or upgrade documentation for additional information.

* JDBC drivers are only available from the DB2 for z/OS product. Additionally, you need db2jcc_license_cisuz.jar in the same directory as db2jcc4.jar.

** The db2jcc.jar has been deprecated and may not be supported in future releases.

*** This .jar file is required for PostgreSQL version 9.1.x.
