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.

Internal rules in search results and explorers

Valid from Pega Version 7.4

Using old: is no longer supported in search. You can include internal rules in search results and make them available in the Application and Records explorers. Include internal rules in search results either by adding the PegaDevelopmentruleset to your application or by clicking the Enable diagnostic features option in your operator preferences.

No longer supported translator configuration options

Valid from Pega Version 7.4

The following translator configuration options are not needed and are no longer supported. If you previously configured any of these system settings, remove them from the system settings to avoid a warning message. For example, if you set translator/useparserfamily, the following message is displayed at startup: "Translator option, 'translator/useparserfamily' is not needed and no longer supported. Remove this from the system settings."

  • translator/useparserfamily
  • translator/usecodegenerator
  • translator/usenativedouble
  • translator/optimization/use71BlockAnalysis
  • translator/optimization/use71ConstantFolding
  • translator/optimization/use71AssignmentTypeSimplification
  • translator/optimization/use71IntrinsicFunctions
  • translator/use71PropSetGeneration
  • translator/use71ParserAssignment
  • assembly/model/useBlock4ContiguousSets
  • /translator/pandc/comparepandcalgorithms
  • /translator/pandc/use6xalgorithms
  • /Compatibility/CheckForTopLevelClassMismatch

In addition, the com.pega.pegarules.generation.parseoverride bootstrap option is no longer supported. Remove this option from the system settings.

pxFeed replaces pxContextFeed and pxActivityFeed Pulse gadgets

Valid from Pega Version 7.4

The pxContextFeed and pxActivityFeed gadgets have been replaced by the pxFeed gadget to integrate the functionalities of viewing and posting messages in the Pulse activity feed. You can include this gadget within a section or harness across your application, for example, in the dashboard of the Case Manager portal, to display the activity feed. You must add the latest UI Kit ruleset to ensure that your application uses the pxFeed gadget instead of the pxContextFeed and pxActivityFeed gadgets to generate the activity feed.

For more information, see Pulse gadget and custom APIs.

Survey rules are deprecated

Valid from Pega Version 7.4

Surveys that were created prior to version 7.4 of Pega Platform are now deprecated. As a best practice, recreate your survey by using the Survey Management landing page, and then reuse questions or question pages from your survey library.

For more information about creating surveys, see Improved survey authoring.

Questionnaire shape replaces Survey shape in legacy flows

Valid from Pega Version 7.4

In flows that reference deprecated surveys, the Questionnaire shape has replaced the Survey shape. Although legacy surveys continue to function in this release, update your flows to use the Survey shape because it provides the latest survey capabilities, and deprecated features are not supported.

For more information about the new survey authoring experience, see Improved survey authoring.

New privilege required to access the Search landing page

Valid from Pega Version 7.4

After upgrading to Pega® Platform 7.4, users who do not have the pxAccessSearchLP privilege cannot access the Search landing page. The pxAccessSearchLP privilege is automatically assigned to the SysAdm4 role. If you have other roles that require access to the Search landing page, you must add the pxAccessSearchLP privilege to those roles.

For more information about assigning privileges to roles, see User privilege authorization. (Link to: basics/v6portal/landingpages/accessmanager/customizeprivilegestab.htm)

PegaDATA connection settings now required in the prconfig.xml file

Valid from Pega Version 7.4

If you use the default prconfig.xml file that is included with Pega® Platform, and you have not removed the PegaDATA connection settings, no action is required. If you use a custom prconfig.xml file, for example, for running tests, ensure that the database connection settings for PegaDATA are not blank.

For more information about the connection settings, see PegaDATA connection settings in the prconfig.xml file.

Add message header fields to the service email for Pulse email replies

Valid from Pega Version 7.4

The pzCreatePulseReply service email rule now has these additional fields in the message header: Message–ID, In–Reply–To, and References. As a result, the system interacts with email clients by using email headers when users reply to Pulse emails. If you configured a service email for replies to Pulse email notifications, add these fields to the service email to allow the system to post the replies in Pulse. If you are creating a service email, ensure that the message header and data have the same values as the values in pzCreatePulseReply.

For more information, see Enabling users to respond to Pulse email notifications.

Applications not working as expected when using fast processing for Connect REST and Service REST integration

Valid from Pega Version 7.4

In Pega® Platform 7.3.1, the Use fast processing option on Connect REST and Service REST rule forms did not work. The functionality has been fixed for Pega 7.4; however, some data model guidelines must be followed. If you use this option in Pega 7.3.1, and you did not follow the guidelines, your application might not work as expected after upgrading. Use the following data model guidelines when using fast processing:

  • The JSON property names and the clipboard property names must match.
  • The JSON tree structure and the clipboard tree structure must be similar.
  • The scalar arrays in JSON must be mapped to the clipboard as page lists.
  • Multi-dimensional arrays must be mapped into page lists of page lists with the same embedded property names.

In addition, page groups, value groups, and Java objects are not supported by fast processing.
