Published Release Notes

Improved search indexing performance

Search indexing now uses a queue processor to improve indexing performance. Indexing can automatically restart if the database goes down temporarily. This saves time and manual action. As a result of using the queue processor for indexing, the following changes have been made to the Search Landing page.

• You cannot cancel indexing from the Search landing page. Cancel indexing by stopping the queue processor from the Data flow landing page.
• The progress message is not shown. View progress on the Queue Processor landing page.
• Queue processor information has been added.

For more information, see Stopping or pausing search reindexing.

More visibility of your production level

You can now see the production level of your environment in a new gadget that is available in all Pega Platform™ workspaces. To ensure that you immediately recognize your current environment, you can give it a unique name that is displayed when you click the gadget. In addition to specifying your production level and environment name on the System form in Dev Studio, you can now specify those values on the System & nodes page in Admin Studio.

For more information on Admin Studio, see Modifying your environment name and production level.

For more information on Dev Studio, see Specifying the production level.

Rule revalidation after updating properties without restarting nodes

When you update certain property attributes, such as a property's maximum length, rule types that reference the property might not reflect the change. You do not always have to restart nodes to revalidate the referencing rules when they cannot be resaved, for example, when they are in a locked ruleset. For Pega Platform™ 8.1 and later, for non-stream rules, such as activities, data transforms, and so on, use the reassemble API in Admin Studio or truncate the assembled classes table.

For stream rules, such as sections, harnesses, paragraphs, and so on, reassemble the rules and restart the nodes. For more information, see More about properties.

For previous versions of Pega Platform, use the System Management Application (SMA) to revalidate stream and non-stream rules.

Changes in JSON results when checking the health of your system

Beginning with Pega Platform™ 8.2, the JSON results that are returned when you ping a Pega Platform instance have changed. JSON results now include node type and health information, including test name, status, state, and node ID. The following samples show JSON results from versions before 8.2 and as of 8.2.

JSON results for pre-Pega Platform 8.2:

{ "duration":"3954.448601", "count":"0" }

JSON results for Pega Platform 8.2 and later:

{"node_type":["WebUser"],"health":[{"last_reported_time":"2019-02-14T16:10:49.589Z","test_name":"Sample-Stream-Check","status":"success"}],"state":"healthy","node_id":"10.10.10_samplenode"}.

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.
