Published Release Notes

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.

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.

Run advanced agents on only one node in a cluster

You can now configure an advanced agent to run on only one node in a cluster at a specified time. In addition, you can specify the time interval within which an advanced agent runs on only one node in the cluster, which avoids having two advanced agents starting to run on the same node at the same time.

For more information, see Improved control for running advanced agents and Agents rules – Completing the Schedule tab.

Ability to test SELECT statements

When developing and debugging applications, you can test SELECT statements from the Query Runner landing page. You can run queries against non-BLOB columns in your database and view the results on the landing page or export the results to an Excel spreadsheet or PDF file. This functionality is available for Pega Cloud customers who use a Postgres database or for customers using an Oracle database on-premises or on the cloud.

To use this landing page, you must have the PegaRULES:DatabaseAdministrator role or the pxDBSelectQuery privilege in Data- and Rule- in your access group. You access the landing page by clicking Designer Studio > System > Database > Query runner.

For more information, see Query Runner landing page for testing SELECT statements.

Elasticsearch 2.4.0 upgrade

The Pega 7 Platform has been updated to use Elasticsearch 2.4.0. You do not have to reindex immediately. You can reindex at your convenience by using the FullTextindexer utility, which provides a smoother transition to the next Elasticsearch library upgrade.

Rolling upgrades are not supported. Instead, after the upgrade has been completed, shut down all the nodes in the cluster, and then restart them beginning with the indexing nodes. For more information, see the Pega 7 Platform Upgrade Guide on the Deployment Guides landing page.

More efficient load management strategies for large data pages

The processing of large data pages on the Pega 7 Platform server during the packaging of offline apps is now faster and much more memory-efficient, especially in environments with many concurrent users. Server communication with the data source is now also optimized by reducing the number of data transfers to only what is needed. In addition, all types of refresh strategies are supported for large data pages.

For more information, see Tutorial: How to use large data pages to store large reference data in offline mobile apps.

Performance enhancements to StringBuilderFactory pooling

StringBuilderFactory has been enhanced to eliminate most scenarios where errors in calling application logic can accidentally cause StringBuilder data contamination within and across JVM thread boundaries. StringBuilderFactory pooling is now thread-specific, which prevents errors in one thread’s use of StringBuilder from contaminating StringBuilder objects in other threads. Debug messages were also added to help diagnose potential problems.

Roll back system changes by using restore points

Restore points save the state of your system, including all rule and data instances. You can roll back to this restore point later if there is a problem. The Pega 7 Platform automatically creates restore points before any archive import. You can also use the prpcServiceUtils command-line tool to create and manage restore points and to roll back changes to your application. For more information, see Restore points.

New Mobile Apps form for defining and building mobile apps

You now create and build mobile apps from the Mobile Apps form instead of from the Mobile tab of the Application rule form. The new console is a control center for mobile apps where you can gather applications, services, components, and settings in one place to fully customize your apps in the Pega 7 Platform. You can create and build one instance of a custom mobile app and define multiple native mobile apps that can use the Pega Mobile SDK. To push notifications to an Android or to an iOS device, you must define an SDK mobile app in the Pega 7 Platform with a certificate set that has push notifications enabled.

For more information, see Configuring a custom mobile app and Configuring push notifications for an SDK app.

Caching of common rules in offline mobile apps

To help start offline-enabled mobile apps more quickly from the time when the server was started, you can now cache common Pega 7 Platform rules, including node scope data pages. Optionally, you can also either cache all node scope data pages, with the exception of the selected ones, or cache only the node scope data pages that are explicitly specified. You set up the offline caching options for your custom mobile app in the Advanced tab of the Access Group rule form.

For more information, see the Offline Configuration section in Access Group form - Completing the Advanced tab.
