Published Release Notes

Search and Reporting does not index large items

When using the Search and Reporting (SRS) microservice in Pega Platform™ 8.5, you might encounter problems with indexing large out-of-the-box rules. The issue is not visible in Queue Processors, but you can access logs to verify which items the system does not index.

Source field not displaying in data transform

On the Data Transform rule form when using the Update Page action, if the Relation value is updated to “with values from”, the Source field will not be displayed.

(Note that for existing data transforms where the Source field has already been completed, this situation should not occur.)

Workaround

1. Below is a data transform that has been configured to use Update Page.
   
2. If a user were to choose an alternate source by updating the ‘with values from’ Relation value, they would not be prompted to provide a page name in the Source field.
   
3. At this point, to be able to enter the Source page value, the user has to save the rule, which results in an error because the source page value is blank. This causes the field to appear.
   
4. Once the field has appeared, the Source page value can be provided, and the form can be saved successfully.
   

Required Oracle optimization parameter

To optimize performance, set the Oracle parameter optimizer_index_cost_adj to a value between 20 and 25. If this value is not set, the system can run exceedingly slowly, potentially blocking users from login.

Synchronized database and application server settings

Configure your database and application server to use the same time zone and character encoding to avoid conflicts.

DCO and PMF integration is unavailable

DCO and PMF integration functionality is not available in this release. Related project management controls have been removed from the following:

• System Settings landing page (Designer Studio > System > Settings > Project Management)
• Application Profile landing page (Designer Studio > Application > Profile > Specifications)
• Add/Edit Specification dialog

Restricted SMA access

System Management Application (SMA) remote connections are not supported on JBoss EAP 6.x. This means SMA users may only monitor locally connected systems. Ensure that the "Local JVM Connection..." option is selected when configuring PRPC nodes:

Stages and Steps may not appear as expected

There are some unique configurations of the newly enhanced pxDisplayStages gadget that can lead to case type "Stages and Steps" appearing more than once or not at all.  In the event that your application experiences one of these scenarios, the recommended work around is to relocate the gadget:

• Add pxDisplayStages to the pyCaseContainer section (or equivalent)
• Remove pxDisplayStages from the pyCaseActionArea section (or equivalent).

Text Input control number type does not validate

When a Text Input control type is set to "Number" in the Presentation tab:

• Validation does not trigger and the field is blanked out when a user submits the form.
• If a value other than a number is entered, the browser sends an empty value, and the value is not validated.
• In the Clipboard, the field value displays as empty.
• If the field is required, the validation displays.

This issue occurs when using both the Chrome and Safari web browsers, and is a result of browser behavior for the HTML5 type=“number”. To fix this issue when using these browsers, do not use the "Number" type in Presentation tab of a Text Input control. Instead, the type should be set to "Text".

Unclear error message when saving shared class instance in tenant layer

If you attempt to save a shared class instance from the tenant layer, Pega 7 displays this message:

This record has x errors. Save Failed: There was a problem saving an instance of class: Error Code: <none> SQL State: <none> Message: <none>

You cannot save a shared instance from the tenant layer if that instance cannot be overridden.

High number of busy waits when using Oracle SecureFiles

You might experience a high number of buffer busy waits when using Oracle SecureFiles for BLOB storage. An Oracle buffer busy wait occurs when a session cannot access a database block in the buffer cache, because another session is either reading the block into the buffer or changing the buffer. As a best practice, use Oracle 11.2.0.4 or later, because earlier versions have more problems with SecureFiles. In addition, to minimize the number of busy waits, set the hidden Oracle parameter _securefiles_concurrency_estimate to 50, and partition the table by using a composite range hash partition that is based on the pxCreateDateTime and pzInskey columns.
