Published Release Notes

DB2-LUW database logfile size increase

To avoid running out of logfile space due to large transaction sets during the rule base load of a Pega 7.1.x install, upgrade, or maintenance level update, systems supported by a DB2-LUW database platform should increase the LOGFILSIZ parameter to at least 4096 pages from the default size of 1000 pages.

After the size has been increased, restart the database to ensure that the new setting is loaded into the database correctly.

Text Input control number type does not validate

When a Text Input control type is set to "Number" in the Presentation tab:

• Validation does not trigger and the field is blanked out when a user submits the form.
• If a value other than a number is entered, the browser sends an empty value, and the value is not validated.
• In the Clipboard, the field value displays as empty.
• If the field is required, the validation displays.

This issue occurs when using both the Chrome and Safari web browsers, and is a result of browser behavior for the HTML5 type=“number”. To fix this issue when using these browsers, do not use the "Number" type in Presentation tab of a Text Input control. Instead, the type should be set to "Text".

Need to run script before updating Multitenant systems

When updating or upgrading a Multitenant system from Pega 7.1.5 or 7.1.6 to Pega 7.1.7, if that system uses either an Oracle or a PostgreSQL database, you may encounter the error:

“Table must be empty to add column.”

The Multitenant architecture requires an additional column on a number of the PRPC database tables (“pzTenantID”). In Pega 7.1.7, two additional PRPC tables were tenant-qualified: pc_schedule_task and pr_index_schedule_task. The Multitenant column is added to these tables by the update/upgrade process. However, Oracle and PostgreSQL do not allow the addition of a non-null column to an existing table unless the table is empty, so updating or upgrading systems on those databases displays the error detailed above.

To avoid this error, before beginning the update or upgrade, it is necessary to run a script:

• Oracle — OracleMTupgrade.sql
• PostgreSQL — PostgresMTupgrade.sql

For updates, these scripts are located in the /scripts/ddl directory.

For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.

Unclear error message when saving shared class instance in tenant layer

If you attempt to save a shared class instance from the tenant layer, Pega 7 displays this message:

This record has x errors. Save Failed: There was a problem saving an instance of class: Error Code: <none> SQL State: <none> Message: <none>

You cannot save a shared instance from the tenant layer if that instance cannot be overridden.

Unit testing support for more rule types

You can now create unit tests for the following additional rule types. You can also create assertions to validate activity status. The expanded rule types for unit testing enable developers to more thoroughly perform regression testing of their application, thereby improving application quality.

• Collection
• Declare expression
• Map value
• Report definition

For more information about unit testing rules, see Pega unit test cases.

Upgrade impact

With the four new rule types, unit test execution and unit test compliance metrics will change. Reports on automated unit testing of the customer application decrease due to the increased pool of supported rules.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, create Pega unit test cases for the newly supported rules to see updated and accurate unit test metrics.

Use Page-Change-Class method to change a Page class

With the release of Pega Platform™ 8.3, using the Property-Set method to change the Page class shows a guardrail warning. Use the Page-Change-Class method to change the Page class instead.

For more information about the Page-Change-Class method, see Changing the class of a page and Page-Change-Class method.

Data and integration troubleshooting enhancements

Identify how data is loaded in user interface (UI) elements, discover the data sources used, and navigate to the relevant rules by using the new Live Data tool. Use the Live Data tool to quickly troubleshoot data and integrations by providing data page information or autopopulate properties from the UI without searching through the clipboard.

For more information, see Troubleshooting data in UI elements.

Retrieve a flat list of fields from Pega Digital Experience APIs

You can now use the flatListOfFields parameter to retrieve a list of the fields in a case or flow action. With this parameter, you avoid parsing all the layout information for the Pega Digital Experience API, making it easier for you to see only what you need to build your user interface.

The following Pega Digital Experience APIs support the flatListOfFields parameter:

• GET /casetypes/{ID}
• GET /assignments/{ID}/actions/{actionID}
• GET /cases/{ID}/actions/{actionID}

For more information, see Retrieve a flat list of fields from Pega APIs.

Drag-and-drop functionality for lists and tables

Lists and optimized tables now support the reorganization of their content by reordering items. By configuring repeating dynamic layouts and tables to support drag-and-drop modifications, you enable users to move items between lists and within lists and tables. This enhancement ensures that you can create a flexible and dynamic user interface that helps users display and manage data.

The drag-and-drop functionality can also include custom actions that automate the processes that run when users move items.

For more information, see Configuring drag-and-drop functionality for lists and Configuring drag-and-drop functionality for tables.

Customized application overview documents in App Studio

Keep stakeholders notified of the status of an application by customizing and generating an application overview document in App Studio. The overview may include information such as case types, roles, features in your application, and more. Select the chapters that you want to include in the overview, and then highlight the most relevant information by ordering the chapters. In addition to the application overview document, you can generate a detailed data model, either in Microsoft Word or Excel format.
