Published Release Notes

Split schema upgrade instructions missing properties

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.

Add additional columns to customized work history tables

The standard work history table, pc_history_work, contains two new columns that return the latitude and longitude coordinate location of the action that prompted the history. Mobile devices can display this location as a street address. If you have a customized work history table, add these two columns to it:

• <decimal name="pxLatitude" size="19" scale="9"/>
• <decimal name="pxLongitude" size="19" scale="9"/>

Updated Word merge support with Microsoft Silverlight plug-in

Starting in this release, Pega 7 features that integrate with the Word merge capability are now cross-browser. ActiveX controls (which are only compatible with Internet Explorer) have been replaced with Microsoft Silverlight. This plug-in must be downloaded separately from Microsoft because it is not shipped with Pega 7.

Common features that are affected by this change include the Specification form and Case Type landing page.

Prior to using these features, see the release note Word merge support with Microsoft Silverlight plug-in for more information about setting up their client systems.

Support for character data type on local variables in activities deprecated

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

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

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

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

@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.

Search indexes require rebuilding after upgrading from Pega Platform 7.1.7 through 7.2.1

Pega Platform™ now supports Elasticsearch 5.6.9. If you are upgrading from Pega 7.1.7 through 7.2.1, discard your existing indexes and build new indexes in a new empty index directory. Create the search indexes by using the Search landing page or the full text indexer. If you are upgrading from Pega Platform 7.2.2 or later, no action is required. You can continue to use your existing search indexes.

For more information, see Rebuilding search indexes and Batch creation and updating of Elasticsearch index files from the command line.

Authentication profile for Connect REST might be removed after upgrade

The Use authentication check box has been removed from the Service tab on the Connect REST form. As a result, after an upgrade, the Authentication profile field might be blank even if an authentication profile was previously configured.

• If the Use authentication check box was cleared prior to upgrading and the Authentication profile field was configured with an authentication profile name, the Authentication profile field is blank. If you are using authentication, you must reenter the profile name.
• If the Use authentication check box was selected prior to upgrading and the Authentication profile field was configured with an authentication profile name, the Authentication profile field retains the previous configuration.
