Failed Robotic Assignments work queue type changed to Standard

Valid from Pega Version 8.5

The default Failed Robotic Assignments work queue type is now Standard. In previous releases, the default type was Robotic. For usage information, see Configuring a work queue for robotic automation.

Upgrade impact

After upgrading to Pega Platform 8.5 and later, you cannot save case types in which you configure the Queue for robot smart shape to route new assignments to the Failed Robotic Assignments work queue. Existing assignments that you routed to the Failed Robotic Assignments work queue are not affected.

How do I update my application to be compatible with this change?

As a best practice, do not use the Failed Robotic Assignments work queue in your custom implementations. Instead, configure the Queue for robot smart shape to route new assignments to a Robotic work queue. When possible, update existing case types to use the robotic work queues that you created in your application.

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

Split schema upgrade instructions missing properties

Valid from Pega Version 7.1.3

If you upgraded from 5.x, 6.x, or 7.x using the instructions in previous versions of the upgrade guide, you may have neglected to set the properties below in your migrateSystem.properties file when you migrated your upgraded schema to the source system:

 

pega.rules.objects.generate=true

pega.rules.objects.apply=true

 

If these properties were not set during an upgrade that splits the schema, your environment does not have the indexes, triggers, and primary keys on the rules tables.

 

To check for this issue, see if the pr4_base and pr4_rule rules tables in your existing rules schema are missing primary keys. If they are, use the SQL scripts in the ResourceKit\MigrationRecoveryScripts directory of the release to cleanup duplicate rules that were created due to this issue. Follow the steps below to run the scripts.

To run the scripts on Microsoft SQL, Oracle, or PostgreSLQ

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
  4. Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  5. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  6. Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  7. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  8. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  9. Optionally upgrade to the latest release, at this point your database is ready to be upgraded or used depending on your needs.

      

To run the scripts on DB2 for LUW or z/OS

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Run the <database>_cleanDups.sql script on the database with vendor tools (UDB CLP, Data Studio, etc) to create the CLEANSE_RULES_DUPS stored procedure.
  4. Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
  5. After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
  6. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  7. Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
  8. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  9. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  10. Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.

Support for character data type on local variables in activities deprecated

Valid from Pega Version 8.1

Support for the character data type for local variables in activities is deprecated. Use the string data type instead.

For more information about activities, see Activities.

When rule might not resolve against @baseclass

Valid from Pega Version 8.1

In the rare case in which a step page context is null, or the pxObjClass associated with the step page is empty, the system no longer attempts to resolve the when rule against @baseclass. As a result, you might see more rule not found errors. Check the step page context and class and ensure that they are not null or empty. In all other cases, if a when rule is not found in any other part of the class hierarchy, the system attempts to resolve it against @baseclass.

DCO Compatibility tool is deprecated

Valid from Pega Version 8.1

The DCO Compatibility tool has been deprecated. Use the Application Guardrails landing page to see the compliance score and any warnings for your application.

For more information, see Application Guardrails landing page.

Apache Ignite is no longer supported

Valid from Pega Version 8.1

Apache Ignite is no longer supported and has been replaced by Hazelcast Enterprise Edition 3.10 in embedded mode. If you used encryption with Apache Ignite, you can configure encryption on Hazelcast Enterprise Edition in the same way that you configured it for Apache Ignite.

For more information about encrypting nodes, see Enabling encrypted communication between nodes.

@java and locatable pages no longer supported

Valid from Pega Version 8.1

@java and locatable pages are no longer supported. Existing rules that use @java and locatable pages will continue to work; however, changes to these rules cannot be saved unless @java and locatable pages are replaced by supported functionality. Use a rule utility function (RUF) instead of an @java page, and use a data page instead of a locatable page. In addition, Pega Platform™ displays a guardrail warning when you open a rule that uses an @java page or a locatable page.

New roles required for system management features and APIs after upgrade

Valid from Pega Version 8.1

The pzSystemOperationsObserver and pzSystemOperationsAdministator privileges are no longer used for accessing system management features in Admin Studio and for system management APIs. Pega Platform™ has new privileges for individual system management functions and new roles configured with these privileges. Use the following roles to access system management features and APIs:

  • PegaRULES:SysOpsAdministrator – has all administrator and observer privileges
  • PegaRULES:SysOpsObserver – has all observer privileges
  • PegaRULES:SysAdm4 – has all administrator and observer privileges

After upgrading, you can include one or more of these roles in your access group or create a custom role. For more information about access roles, see Access roles.

Enabling access to upgraded help
