Published Release Notes

Child case queries performance can be slow

Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.

See Performance improvements for child case queries.

Updates to the Data Page rule form

You can use the enhanced Data Page rule form to specify the name of a source system in the System name field in the Data sources section. This field represents the name of the system that is associated with a data source. For example, if your data source is a REST connector that connects to an external weather service such as Google Weather API, you can enter Google Weather in the System name field for the data source. The system name is used to display the source systems for a data type on the External Data Entities landing page.

For more information, see Viewing external data entities.

Verify ML Readiness error: Upgrades from Pega 7.1.0 through 7.1.8 do not replace nonversioned rules

Upgrading from any Pega 7 Platform version between Pega 7.1 and Pega 7.1.8 to Pega 7.2 does not automatically replace nonversioned rules. If you revalidated and saved a Pega 7.1.x rule after the timestamp on the Pega 7.2 version of the rule, upgrading to Pega 7.2 does not overwrite the saved rule. You might see either of the following behaviors:

• The upgrade fails with the following error message:
  Verify ML Readiness
• The upgrade succeeds, but you might be unable to open changed rule forms.

If the upgrade fails, see the Pega 7 Platform Upgrade Guide to force the upgrade.

This known issue does not affect Pega 7.1.9. After the upgrade has finished, apply Hotfix 27288. For information about obtaining and applying hotfixes, see Hotfix Manager.

Compare rule versions in a rule form

You can now compare different versions of rules from the Actions menu when you work within a rule form instead of using the Rule Compare utility. You can inspect changes that were made between versions directly on the rule form, make updates, and save any changes to the rule form.

For more information, see Rule version comparison within a rule form.

Performance improvement to BLOB support in Postgres databases

New tables that contain BLOB columns now use external storage instead of expanded storage for Postgres databases. This improvement applies to tables that are created during installation, upgrade, or during DDL and schema generation. Using external storage improves database performance.

For more information, see BLOB storage in Postgres databases.

Unused agents run in background

The Update PegaRULES database table statistics agent and the Collect PegaRULES database blob size statistics agent have been added to support future development. These agents run in the background, but they do not do anything. You can, but do not need to, disable them from the Edit Agent Schedule landing page.

For more information, see Agent Schedule form - Completing the Schedule tab.

View all nodes in a cluster from the Cluster Management landing page

Use the Cluster Management page to view information for all of the available nodes in a cluster. To view the nodes, click Designer Studio > System > Operations > Cluster Management. To access detailed information about a single node, click Actions.

For more information, see System Operations.

Automatically manage nodes in a System Management Application cluster

Instead of manually adding and deleting nodes in a cluster by using the System Management Application (SMA), you can now automatically manage nodes. You can enable Auto Node Discovery and configure it to get information about all the nodes in a cluster, add new nodes, and update the node list.

For more information, see Managing nodes automatically in a System Management Application cluster.

Logic-based assignment routing

You can now define business logic that controls when and by whom an assignment is processed in a case. By routing assignments to a specific user or group of users, you can help ensure that cases are resolved faster.

For more information, see Logic-based assignment routing.

Show multiple views of data in your application

You can now show multiple views of data in your application by adding the record editor (pxRecordsEditor) section to a layout, another section, or a cell in a layout. You can configure the section to customize the display and enable the search, import, and export capabilities of the record editor.

For more information, see Multiple views of data in the record editor section.
