Published Release Notes

End of support for Microsoft Internet Explorer 8 and quirks mode applications in Pega 7.1.9

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 8 in January 2016, Pega 7.1.9 does not support Internet Explorer 8, nor does it support non-HTML5 standard user interfaces.

You must upgrade to Microsoft Internet Explorer 9 or later or use Google Chrome, Apple Safari, or Mozilla Firefox. If you are using Internet Explorer 9 or later, you must turn off compatibility mode by accessing the Compatibility View settings.

Note the following:

• Pega 7.1.9 does not support user interface rules that are not based on HTML5 standards (rules in quirks mode).
• If you use applications that are rendered in quirks mode, which enables Pega 7 to correctly display and render non-HTML5 standard user interfaces, you must update them to standards-based HTML5 user interfaces when you upgrade to Pega 7.1.9 or later. Pega 7 provides automated tools to help you migrate your applications.
• Pegasystems Global Customer Support will not investigate or fix any Pega 7.1.9 bugs or support requests that are exclusive to Internet Explorer 8 or quirks mode user interfaces.

You can quickly identify which components of your application user interface are not HTML5 standards-based by clicking Designer Studio > User Interface > HTML5 Application Readiness.

Upgrading to Pega 7.1.9 and a newer browser offers the following benefits:

• These browsers are HTML5 and CSS3 compliant.
• New features are supported and existing features work as intended.
• The Pega 7 Platform user interface is displayed and rendered as intended.
• Browser security is enhanced.

If you have additional questions about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

Real-time pulse processing for multinode systems

Multinode development environments now use real-time pulse processing. Previously, when a change was made on one node, the pulse processing interval could take a minute or more for that change to be reflected on another node. Now, when a rule is changed on one node, that change is immediately reflected on all the other nodes in the cluster. This change helps to ensure that users are running a rule on the same node as where the rule was changed.

Verifying that a Pega 7 Platform instance is running

You can verify whether a Pega 7 Platform instance is up and running by entering this URL: http://<<hostName:port/contextName>>/PRRestService/monitor/pingservice/ping

The Pega 7 Platform Engine responds with HTTP Response Code 200 if the instance is available. The response contains JSON text in the format { "duration":"<time in milliseconds>" }. Any other response codes or timeout indicate that the instance is unavailable.

Updated default system pulse processing settings

The default settings for system pulse processing have been updated in this release.

Upgrades to Pega 7.1.9 from a previous version of the Pega 7 Platform use database pulse by default. Database pulse synchronizes rule changes at a periodic interval across all nodes in a system.

New installations of Pega 7.1.9 use cluster-based pulse by default. Cluster-based pulse immediately updates rule changes across all nodes in a system after the changes are saved.

You can change the database pulse setting to the cluster-based pulse setting by updating the value attribute for initialization/pulse/transport to "cluster" in the prconfig.xml file or in the Dynamic System Settings. Changing from database pulse to cluster-based pulse requires a full cluster restart after the changes are made.

For more information, see Pega-RULES agents.

Database storage used for passivation in High Availability mode

When an application is running in High Availability mode, the value attribute for initialization/​persistrequestor/storage in the prconfig.xml file or the Dynamic System Settings​ now defaults to "database."

Previously, applications running in High Availability mode required shared passivation, where either initialization/​persistrequestor/storage was set to “OnTimeout” or a custom passivation mechanism was used. The change to using database by default provides persistent storage for passivation, and provides control for the landing page for High Availability.

For more information, see Understanding passivation and requestor timeouts and the High Availability Administration Guide.

PegaDISTRIBUTION Manager (PDM) is no longer available

The PegaDISTRIBUTION Manager (PDM) is no longer available in the Pega 7 Platform. The related PDN articles and help topics have been archived.

Primary key constraint error when using JBoss

A primary key constraint violation exception might occur in the following situation: you use JBoss EAP 6.4 and SQL Server 2012 with a JDBC 4 driver, and you use two or more file listeners or JMS MDB listeners with concurrent threads that create work objects that use multiple files. If a primary key constraint violation exception occurs in this situation, update the data source configuration file to set the jta parameter to true. For example, set <datasource jta="true" jndi-name-"java:/jdbc/PegaRULES>.

App Studio enhancements further support Pega Express methodology

App Studio now includes improvements that you can use to plan your Microjourney™ in a more convenient way. The Overview workspace now includes a button to edit application details, such as name, description, and business objectives, without having to switch to Dev Studio. You can also access relevant information faster, because Case Designer displays additional details about channels, data objects, and attachments associated with a case type directly in a properties pane. For improved management of your features, feature categories are now available in the application inventory so that you can clearly communicate to your development team what type of features need implementation.

• Editing application details in App Studio 
• Associating personas with channels 
• Adding features to application inventory 
• Creating a Microjourney for customer success

Enhanced mapping of personas and users in App Studio

App Studio now provides a consistent and transparent experience when mapping personas to users. When you invite users to your application, you can associate each user with a run-time persona or developer role by selecting an option from a clearly organized list. For example, you can associate run-time users with a customer service representative persona, and then invite a person to help develop your application and assig them a developer role. For greater clarity, personas now replace references to roles in App Studio.

For more information, see Inviting collaborators to your application.

Tracer support for Cosmos React

The Tracer tool is now available for stateless applications, so that you can trace and debug applications that you build on Cosmos React. Because in a stateless application multiple requests can run simultaneously, to provide clarity, Tracer shows the events by request ID instead of grouping the events by the time of occurrence. For greater convenience, debugging Cosmos React applications is also available in an offline Tracer tool. As a result, you speed up the development process and deliver top-quality applications that are free of bugs.

• Debug your Cosmos React applications faster with Tracer (8.6)
• Application debugging by using the Tracer tool
• Pega Digital Experience (DX) API
