Specify the scope for rolling back rules and data to a restore point

Valid from Pega Version 8.4

Create restore points to save the state of all rules and data in your system at a significant point in time, for example, before you import an application. Roll back to that restore point to return the system to that state. Now, you can filter which rule and data instances are returned to their previous state:

  • System: Roll back every rule and data instance that has a history record.
  • User: Roll back rule and data instances modified by a specific user. If any rule was changed by more than one user, you will see an error message and must use the system rollback.
  • Application: Roll back rule and data instances in a specific application.

For more information, see Using restore points to enable error recovery.

Rules can no longer access Pega internal Java packages

Valid from Pega Version 8.4

You can no longer create rules that access Java packages that reference internal APIs (syntax com.pega.platform.*.internal*). This change does not affect rules that access Pega public API packages.

If you encounter issues when running existing rules that reference internal Pega APIs, contact Pega Support.

Upgrade impact

After an upgrade to 8.4 and later, clients can no longer save new or modified rules that access Pega internal APIs; existing rules that reference internal APIs can still be run but cannot be modified. 

What steps are required to update the application to be compatible with this change?

Following a software upgrade to 8.4 or later, clients can refactor existing rules into guardrail compliant rules. To find rules to refactor, run the validation tool from designer studio (Application > Tools > Validation) to identify what rules fail validation; failed rules that include the message "Test compilation failed : Illegal internal class reference : com.pega.internal.XYZ" can updated to reference appropriate APIs.

Client-server deployment of Hazelcast

Valid from Pega Version 8.4

Pega Platform now supports the client-server model for the Hazelcast service, which provides cluster communication and distributes Pega Platform features across nodes. This optional deployment model introduces independent scalability for both servers and clients in Pega Platform, improving stability for deployments that use a large number of nodes.

The Hazelcast client-server model is intended for select environments running Pega Platform 8.4 across a large number of nodes and should be deployed only when directed by Global Client Support.

Improved indexing performance by gradual retrieval of data

Valid from Pega Version 8.4

Search functionality in Pega Platform™ versions from 8.4.5 to 8.6 now includes the option to improve indexing performance when reading query results from a large table in a database. For example, to load the recommended 50 records at a time, in the Pega-SearchEngine ruleset, create the indexing/distributed/fetchsize dynamic system setting, and set the value to 50.


Creating the fetchsize dynamic system setting ensures that your system does not crash while indexing classes with numerous instances.

For more information, see Creating a dynamic system setting.

Additional upgrade scripts for new columns

Valid from Pega Version 7.1.4

In Version 6.2, additional columns (Major, Minor, and Patch) containing ruleset Version information were added to 15 tables in the PRPC database. When upgrading from a pre-Pega 7 release, scripts must be manually run after the upgrade to populate these columns.

These scripts are located in the Resource Kit, under Additional Upgrade Scripts.

  • If upgrading to a single schema, run both scripts.
  • If upgrading to a split schema, run the _data script against the data schema and run the _rules script against the rules schema.
  Depending upon your database type (platform) and the size of your database, these scripts may require significant time and system resources to run.

Choose the scripts for your database type:

  • db2zos_rulesetversion_columns_data.sql
  • db2zos_rulesetversion_columns_rules.sql

 

  • mssql_rulesetversion_columns_data.sql
  • mssql_rulesetversion_columns_rules.sql

 

  • oracle_rulesetversion_columns_data.sql
  • oracle_rulesetversion_columns_rules.sql

 

  • postgres_rulesetversion_columns_data.sql
  • postgres_rulesetversion_columns_rules.sql

 

  • udb_rulesetversion_columns_data.sql
  • udb_rulesetversion_columns_rules.sql

Database

Valid from Pega Version 7.1.4

Improvements to data handling were made for search indexing, agent processing, and filtering.  Scripts were provided for proper population of the database tables.

 

  • Importing data from shared obj-external tables is now supported.
  • A validation warning will now display when an unexposed property is used in filter or join conditions.
  • A Global Search index may now be created across two databases.
  • Agent processing on multiple nodes has been improved.
  • Improvements were made to controls in Report Definition pages which are used in a dynamic grid.
  • Filtering functionality involving special characters has been enhanced.
  • Scripts have been provided to populate the RuleSetVersion Major, Minor, and Patch columns.

DCO

Valid from Pega Version 7.1.4

This release focused on improving the user experience of creating new rules and tightening up the use of specifications in the Case Designer.  The layout of the New and Save As forms were made more intuitive and intelligent.  Specification actions were made to be more consistent across various aspects of the Case Designer.

  • After removing specification references, users can create and save a new specification.
  • Developers may now choose either an existing specification or create a new one for subflows and Split-For-Each shapes.
  • If a specification is not associated with flow shapes such as sub flows, Utilities, or Split-For-Each, it is possible to import speciications with the same names, and the flow shapes will default to using those imported specs.
  • In the outline view, specification changes will be preserved when switching from tab to tab.
  • The View Full Details functionality from either Configure Step or the Outline View will display all details, including the specification requirement links.

System Management

Valid from Pega Version 7.1.4

Refinements were made to out-of-place upgrade documentation and processes, as well as for how handling is performed for all of the database vendor specific nuances related to a deploying into a split schema environment.

  • A script was created to run the data schema upgrade for z/OS systems.
  • In a split-schema configuration, indexing has been enhanced.
  • The product installer has been enhanced.
  • The stand-alone Static Assembly Utility does not require a password for its process.
  • The UpdateManager tool has been improved.

Node description cannot match application server node name

Valid from Pega Version 6.3 SP1

A node's Short Description should not be the same value as the application server node name. If the node's Short Description is changed to be the same value as the application server node name, then the node description is automatically changed back to the original value after a system restart.

Enhanced date circumstancing option

Valid from Pega Version 7.2

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.
