Performance improvement to BLOB support in Postgres databases
Valid from Pega Version 7.2.2
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
Valid from Pega Version 7.2.2
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.
Show multiple views of data in your application
Valid from Pega Version 7.2.2
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.
Support for additional rule types for PegaUnit test cases
Valid from Pega Version 7.2.2
To compare the expected results with the results that are returned by running a rule, you can now create PegaUnit test cases for the following rule types:
- Activities
- Data transforms
- Strategies
- Decision trees
- Decision tables
After you unit test these rules, you can convert them to test cases and configure assertions on the test cases. You can also set up the clipboard with data before tests are run, and clean up the clipboard after tests are run.
For more information, see PegaUnit testing.
Page assertions are supported for PegaUnit test cases
Valid from Pega Version 7.2.2
You can now create page assertions for PegaUnit test cases. Because data transforms and activities can create or remove pages, you can configure page assertions to determine whether a page exists after you run PegaUnit test cases.
For more information, see Configuring page assertions.
Run advanced agents on only one node in a cluster
Valid from Pega Version 7.2.2
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
Valid from Pega Version 7.2.2
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 .
For more information, see Query Runner landing page for testing SELECT statements.
Authenticate REST data sources by using OAuth 2.0
Valid from Pega Version 7.2.2
You can now authenticate the data sources that are created from your REST integration by configuring OAuth 2.0 authentication in the New REST Integration wizard. You can specify or create an OAuth 2.0 authentication profile in the wizard by using the client credentials or authorization code grant type.
For more information, see OAuth 2.0 in REST integration.
Elasticsearch 2.4.0 upgrade
Valid from Pega Version 7.2.2
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.
Performance enhancements to StringBuilderFactory pooling
Valid from Pega Version 7.2.2
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.
