Default value of the threadpoolsize agent affects batch indexing

Valid from Pega Version 8.5.2

After you patch Pega Platform to version 8.5.2 or higher, the system changes the default value of the threadpoolsize agent, which controls the number of concurrent activities (threads) in the system, from 5 to 15. Batch indexing in Pega Platform does not require all 15 threads, so you can change the agent value to increase system performance by managing the indexing/distributed/batch/numworkers dynamic system setting.
If your deployment does not support that setting, and batch indexing does not use Queue Processors, the system uses the threadpoolsize value for batch indexing instead.

For more information, see Editing a dynamic system setting.

Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6

Valid from Pega Version 8.6

Pega Infinity™ uses Hazelcast distributed clustering technology to share data and send events between server nodes. Beginning in Pega Infinity release 8.6, Pega Infinity supports Hazelcast 4.x.
 
Note: Note: Because Hazelcast 3.x is in extended support, upgrade to Hazelcast 4.x before the extended support period for Hazelcast 3.x ends.

Upgrade impact statement

On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.

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

Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.

For instructions about upgrading to Hazelcast 4.x, see one of the following topics:

Improved indexing of StringList and StringGroup property types

Valid from Pega Version 8.6

Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.

Upgrade impact

After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed. 

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

On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.

For more information, see Indexing class data.

 

Flow rules not supported in IE8

Valid from Pega Version 7.1.1

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.

Updated Word merge support with Microsoft Silverlight plug-in

Valid from Pega Version 7.1.3

Starting in this release, Pega 7 features that integrate with the Word merge capability are now cross-browser. ActiveX controls (which are only compatible with Internet Explorer) have been replaced with Microsoft Silverlight. This plug-in must be downloaded separately from Microsoft because it is not shipped with Pega 7.

Common features that are affected by this change include the Specification form and Case Type landing page.

Prior to using these features, see the release note Word merge support with Microsoft Silverlight plug-in for more information about setting up their client systems.

Search field type is deprecated

Valid from Pega Version 7.1.9

The search field type in Form Builder is deprecated. Use a data reference or user reference instead, both of which prompt users with an autocomplete field at run time.

For the full list of supported field types in Form Builder, see Supported display modes by field type.

WriteHistory parameter has been removed from Link-Objects method

Valid from Pega Version Pega Platform

The WriteHistory check box has been removed as a parameter to the Link-Objects method on the Activity form. Users who are upgrading from versions prior to Pega 7.2 do not have to take any action because history details rely on the "linked from" object and this option stored results in the "linked to" object.

To correctly capture a link event in the history of an object, call the History-Add method.

Label changes to field types in Case Designer

Valid from Pega Version 7.2

The following field types have been renamed in Case Designer to be consistent with Data Designer and other areas of the Pega 7 Platform.

Label in previous versionsLabel in Pega 7.2
TextText (single line)
Text (multiple lines)Text (paragraph)
Check boxBoolean
Date and timeDate & time
DateDate only
Drop downPicklist
Number (integer)Integer
Number (decimal)Decimal

Users who upgrade from versions prior to Pega 7.2 do not have to take any action because the label changes are cosmetic and do not affect the underlying controls or property types that support form building.

For more information about the field types that you can use when building a form, see Storage and display of single-value fields.

Process Outline view is unavailable

Valid from Pega Version 7.2

Process Outline view is no longer available as of this release. Use Case Designer instead to configure your processes. For advanced options, you can open the underlying flow for a process in Process Modeler.

For more information, see Designing a case type and Diagram tab on the Flow form.

New location for case-type settings

Valid from Pega Version 7.2

The configuration options for case-type settings have been moved from the property panel to the Settings tab in Case Designer. This change separates behavioral settings from life-cycle settings so that you can stay focused as you design your case types.

For more information, see Configuring case-type behavior.
