Published Release Notes

Extract data from Pega Cloud to an on-premises database

You can now use Pega^® Business Intelligence Exchange (BIX) to extract data from Pega Cloud to an on-premises relational database management system. Extracting data from Pega Cloud directly to an on-premises database improves efficiency by eliminating the need for file extraction and the development of a file extraction infrastructure.

For more information, see Extracting data from Pega Cloud to an on-premises database.

Improved connection pooling performance

HikariCP is now used for connection pooling for databases that are configured by using a URL. HikariCP improves connection pooling performance; however, more database connections might be used than in previous versions of Pega^® Platform.

As a result of the switch to HikariCP, you cannot use the System Management Application (SMA) to get diagnostic data from your application. For instructions about how to get diagnostic data by using REST services, see Obtaining connection pool diagnostic data by using REST services.

No longer supported translator configuration options

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.

System state data is saved for 90 days

System state data is now saved to the database for 90 days and can be downloaded as a JSON file. Having previous system state data available is useful for debugging system problems. Operators with the pzSystemOperationsObserver privilege can download system state data from the Cluster Management landing page for either the entire cluster or a single node. In addition, the PersistClusterState and PersistNodeState agents have been added to the Pega-RulesEngine ruleset for persisting system state data to the database.

For more information, see Downloading the system state.

PegaDATA connection settings now required in the prconfig.xml file

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.

Node classification replaces NodeID-based configuration

For simpler cluster administration and better application resiliency, Pega^® Platform is moving toward a node classification model. Although agents will continue to work by using NodeIDs for several upcoming releases, use node types instead of NodeID configuration for agents, listeners, and decisioning services for more efficient operations and upgrades.

For more information, see Node classification.

WSDL generation error prevents invocation of SOAP services

Status

A Known Issue was introduced in the 8.4.2 Pega Platform patch release, which impacts both upgrades and new installations of that version.

Description

Due to changes introduced in the SOAP functionality for the case-mismatch error in SR-D98509/INC-119725, the WSDL is being generated for SOAP services with an incorrectly-capitalized element, which prevents the service from being invoked.  The element should be “name” instead of “Name”.

Workaround

Clients must perform the following workaround after they define a new SOAP connector in Pega Platform:

1. To download the WSDL from Pega Platform:
   1. After using the SOAP Wizard (Dev Studio > Configure > Integration > Services > Service Wizard) the WSDL URL is shown at the bottom right of the Dev Studio screen.
   2. Click the URL to display the XML.
   3. Save the WSDL file to your local system.
2. In the text editor of your choice, modify "Name" to "name" in every <element “name” = … > tag in the WDSL.
3. Save your changes to the local file.
4. To reload the WSDL into Pega Platform:
   1. In Dev Studio, open the Configure menu.
   2. Select Integration > Connectors > Create SOAP Integration.
   3. In the New SOAP integration wizard, select Upload WSDL from File.
   4. Complete the upload using the wizard prompts.

This is a design-time issue, not a run-time issue; therefore, clients only have to perform this workaround process once. Existing SOAP services should not be impacted; however, if clients modify an existing SOAP service definition by re-running the wizard, clients must reapply the workaround for Pega Platform to recognize the SOAP definition changes.  

Resolution

This issue will be addressed in the Pega Platform Patch Release 8.4.3.  Clients who upgrade to that version or later should not see this issue.
