Updated default dynamic system setting for requestor pools

Valid from Pega Version 8.4

Clients can now enable or disable requestor pools for processing service requests using a new dynamic system setting called EnableRequestorPools with Pega-IntegrationEngine as the owning rulest. Previously, all deployments utilized requestor pools to improve service processing response efficiency; requestor pools eliminated overhead by automatically returning a requestor to the pool after it fulfills a service request. Starting in Pega Platform 8.4, requestor pools are disabled in Client-managed cloud deployments, since these deployments use autoscaling to handle service request traffic. Enabling requestor pools in Kubernetes environments is not recommended, because they can inhibit the default autoscaling settings in the environment.

Requestor pools remain enabled by default in Pega Cloud and on-premises environments.

To help clients navigate this change, Pega has updated its best practice guidance for configuring requestor pools. For an overview, see Requestor pooling for services. For guidance on the use of requestor pools in your application, see the EnableRequestorPools entry in Dynamic system settings data instances.

Upgrade impact

Requestor pools are disabled by default in Pega Platform 8.4 in client-managed cloud deployments. Clients who deployed previous versions of Pega Platform on a Kubernetes environment and who upgrade to Pega Platform 8.4 could see that their services behave differently.

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

If clients that are deployed in a Client-managed cloud environment need to configure their services to use requestor pools and they understand how to configure requestor pools for their optimized use, these clients can re-enable requestor pools. Clients should review the best practice for configuring requestor pools before they re-enable requestor pools. To re-enable requestor pools, you modify the EnableRequestorPools setting in the Pega-IntegrationEngine Owning ruleset from “disabled” to Enabled [no value]. For details, see Editing a dynamic system setting.

Email Wizard support discontinued

Valid from Pega Version 8.4

Pega Platform™ no longer includes the Email Wizard. This wizard helped set up an email service for sending and receiving email in Pega Platform. The wizard generated an email account, an email listener, and an email service rule.

After an upgrade to Pega Platform 8.4 and later, existing clients must create new email accounts and email channels in App Studio. When you configure a new email channel, you add your email accounts so that customers can send and receive email by using the Pega Email Bot. Configuration of an email channel automatically generates an email listener and service email rules.

For more information, see Creating an email account and Building an Email channel.

Customizations to the prlogging.xml file must be manually ported after upgrade

Valid from Pega Version 7.3

As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the name of the logging configuration file has changed from prlogging.xml to prlog4j2.xml and the format of the file has changed considerably. If you customized your prlogging.xml file, port the customizations to the new prlog4j2.xml file. If you do not port the changes, the Pega® Platform uses the default prlog4j2.xml file and disregards your customized prlogging.xml file.

For more information about customizing your log files, see the Apache Log4j 2 documentation.

Socket server has changed for remote logging

Valid from Pega Version 7.3

As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the socket server that is used for remote logging has changed from the Log4j remote logging package with the LogFactor5 log analysis tool to TcpSocketServer. If you use remote logging, update your socket server to TcpSocketServer. For more information, see Installing and using remote logging.

Requestor Management landing page access privileges

Valid from Pega Version 7.3

To access the Requestor Management landing page after upgrading to Pega® Platform 7.3, you need to add the appropriate privileges to the @baseclass and Pega-Landing access classes in the access roles. Apply these privileges to any application in which you want the operator to be able use the requestor management feature.

For more information, see the Requestor Management landing page and the appropriate Deployment Guide.

Pulse Extension points are deprecated

Valid from Pega Version 7.3

Beginning with Pega® Platform 7.3, Pulse uses the notifications feature to send notifications. As a result, Pulse extension points for email body, subject, and recipient list have been deprecated. Preferences set for Pulse notifications in earlier versions are no longer valid.

Use the alternatives listed in the following table to configure your Pulse message and notification preferences.

To continue using the deprecated extension points, override the pyInvokepxNotify when rule and set it to return false.

Deprecated survey APIs

Valid from Pega Version 7.3

APIs that were available in the PegaSurvey ruleset have been superseded by Pega® Platform APIs. Although older APIs continue to function in this release, it is recommended that you update your flows and flow actions to use the new APIs because they provide the latest survey capabilities, and deprecated features are not supported.

The following table maps deprecated APIs to their replacement APIs.

Deprecated APINew APIDescription
Work-.QuestionShapeWork-.pzQuestionShapeA flow that displays one simple question.
Work-.QuestionShapeScrWork-.pzQuestionShapeScrA screen flow that displays one simple question.
Work-.SurveyDriverWork-.pxSurveyDriver

A flow that displays questions in a survey, which can be simple or complex.

You can control whether the questions are displayed on one or multiple screens.
Work-.SurveySectionWork-.pxSurveySection

A section that displays questions in a survey.

You can reference this section from a user action, such as a flow action or connector flow action, in a flow.

Log file description in web.xml incorrect after upgrade to Apache Log4j 2

Valid from Pega Version 7.3

As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, it is recommended that you update the log file description in the web.xml file from location of prlogging.xml file to location of prlog4j2.xml file. The description indicates which log file is in use. Updating the description avoids confusion about which log file is current. Change the description as shown in the following example.

<resource-ref id="ResourceRef_5">
<description>location of prlog4j2.xml file</description>
<res-ref-name>url/pegarules.logging.configuration</res-ref-name>
<res-type>java.net.URL</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

Locatable pages are deprecated

Valid from Pega Version 7.3.1

Locatable pages are deprecated. Use a data page instead. Data pages provide improved performance. When you save a rule that has a Locate Page Activity or when you create an activity of type Locate page, a guardrail warning is displayed indicating that this feature has been deprecated.

For information about data pages, see Data pages.

Use of the @java function in expressions is deprecated

Valid from Pega Version 7.3.1

Use of the @java function in expressions is deprecated. Use a utility function or other product feature instead.

For more information about expressions, see Building expressions with the Expression Builder.
