Published Release Notes

Enhanced date circumstancing option

The date range and as-of date circumstancing features have been merged into a single feature called date circumstancing. Accordingly, the new Property and Date circumstancing option provides more flexibility when you circumstance a rule. For more information, see Specializing a rule.

Renaming a system creates the required data requestors

When you rename a system, either from the System Name landing page or by updating the prconfig.xml file, any missing data requestors are automatically created by the Pega 7 Platform. The Data Admin System Setting is also created, if it is missing.

Configure Elasticsearch index nodes to ensure availability of index files

You can now configure Elasticsearch index host nodes in a Pega cluster outside of the Search landing page. This change ensures that search index files are always available by eliminating the need for manual configuration on the Search landing page. Use the new index.directory=<index_directory> command-line setting during JVM startup to indicate that this node is an index host node and to specify the directory where the index files will be hosted.

In addition, offline Elasticsearch index nodes can now be removed by using a new prpcUtils command-line option. For more information, see Managing Elasticsearch index host nodes outside of the Search landing page.

New Schema Tools and Query Inspector landing pages for Pega Cloud

Two landing pages have been added for advanced database administration tasks for Pega Cloud customers who use a Pega-hosted instance. These landing pages minimize the operations that need to be performed outside of the Pega 7 Platform. They are available only for customers who use a Postgres database.

From the new Schema Tools landing page, you can view PegaRULES and PegaDATA database schemas, increase the size of a column, add a composite or function index, update database statistics for a table, and defragment a table.

From the new Query Inspector landing page, you can enter an SQL query and generate an explain plan.

To use these landing pages, you must have the new PegaRULES:DatabaseAdministrator role. You access the landing pages by clicking Designer Studio > System > Database > Schema Tools or by clicking Designer Studio > System > Database > Query Inspector. The individual features that you can access are determined by the privileges that are assigned to you.

For more information, see Schema Tools and Query Inspector landing pages for tuning and maintaining databases in the Pega Cloud.

Custom properties can be passed to an Oracle database

You can pass a customizable set of property values to an Oracle database when a connection is established so that an SQL statement can be run. This feature provides the ability to implement object-level security for data access from a Pega 7 Platform application by defining Virtual Private Databases (VPDs) on class tables that reference the information passed. For example, you could pass in an operator's branch office into the context of every query run against the Oracle database to ensure that the operator has access only to data that is applicable to the operator's branch.

This feature is available only for Oracle databases and for a Data-Admin-DB-Name instance that is not PegaRULES or PegaDATA, and has the same connection metadata (JNDI, URL) as PegaData.

See Passing custom properties to an Oracle database.

Pega 7 Platform supports X-Forwarded-* (XF*) HTTP headers

When deployed behind a load balancer, the Pega 7 Platform can formulate absolute URLs while responding to requests, without any additional configuration. The load balancer must be configured to use XF* headers. Consequently, the configuration property contextrewriteenabled is deprecated.

Improved application performance when responding to SOAP requests

When an application serves multiple requests, the contention placed on the ContextHash class is reduced because all threads can concurrently access the mHash instance variable, which improves performance. To experience this benefit, redeploy the prweb.war file for web tier deployment or redeploy the prpc_wls_jee4.ear file for e-tier deployment.

Enhanced performance of autopopulated properties

You can improve performance when accessing data from autopopulated properties that are defined by keys or parameters. If the properties were created in an earlier version of the product, run the pzReSaveAutoPopulateProperties activity to gain a performance improvement.

For more information, see Enhancing performance when loading autopopulated properties.

Support for large reference data in offline mobile apps

A data page in a Pega 7 Platform mobile application with offline capability enabled can now be marked as a large data page. This feature improves performance significantly when you have a large amount of data in which only individual records change.

In this situation, after the initial sync to the mobile app, only the changes in the large data page are synced instead of the entire large data page. The database table is created for such large data pages in the encrypted SQLite database on the device. Changes such as add, delete, or update are reconciled as row-level updates. Furthermore, you can use JavaScript to query against this data. A large referenced data page is supported by list-based components such as repeating dynamic layout, auto-complete, a dropdown list, and radio button.

Support for offline and online cases in a single mobile app

A single offline-enabled application can now support both the creation and processing of online-only and offline-ready cases.

For online-only cases, a list of both the offline and online cases is always available. Case assignment and processing is performed on the server so that a case is available only when the device is connected to the Internet or to data. When a connection is not available for processing an online-only case, an error message is displayed.

For offline-ready cases, a user can open an assignment and perform tasks on that case. There is also an option to explicitly display a harness from a server instead of a client store.
