Change logic does not work in Report Editor
Valid from Pega Version 7.1.2
The Report Editor change logic button does not work. As a workaround, use the rule form to change the logic.
Required Oracle optimization parameter
Valid from Pega Version 7.1.3
To optimize performance, set the Oracle parameter optimizer_index_cost_adj to a value between 20 and 25. If this value is not set, the system can run exceedingly slowly, potentially blocking users from login.
Slow WebSphere performance on Mac platforms
Valid from Pega Version 7.1.2
Use the following JVM setting to improve WebSphere performance on Mac platforms:
-Djava.net.preferIPv4Stack=true
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
- Take down any app servers using the affected schema.
- Backup your database.
- Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
- Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
- 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.
- 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.
- 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
- Take down any app servers using the affected schema.
- Backup your database.
- 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.
- Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
- After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
- Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
- 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.
- 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.
- Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.
Synchronized database and application server settings
Valid from Pega Version 7.1.3
Configure your database and application server to use the same time zone and character encoding to avoid conflicts.
Split schema systems require additional privileges
Valid from Pega Version 7.1.2
On Oracle split schema systems, add the following database privileges:
- Grant DROP ANY INDEX to the Admin User.
- Grant UNLIMITED TABLESPACE to the Rules User.
Use the Oracle Enterprise Manager to add these privileges or refer to the 7.1.3 Upgrade and Installation guides for Oracle.
Updated Word merge support with Microsoft Silverlight plug-in
Valid from Pega Version 7.1.3
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.
Improved case auditing in App Studio
Valid from Pega Version 8.5
In Cosmos UI, App Studio now supports expandable case steps. This enhancement helps users quickly navigate a case and provides deeper insight into the case flow. In addition, Cosmos UI also introduces an improved history view that helps you better meet your business auditing requirements.
For more information, see Managing Cosmos UI settings in case designer.
Upgrade impact
After an upgrade to Pega Platform 8.5 or later, the history and chevron designs change automatically. However, applications with custom history settings might still display the styling that you defined in the override.
What steps are required to update the application to be compatible with this change?
If your application uses custom settings and you want to use the updated history, remove the overrides from the pyWorkCommonActions rule.
Removal of Pega Mobile Client 7
Valid from Pega Version 8.5
You can now use a single Pega Mobile Client™ that improves app performance, app development, and meets all your mobile needs. With the introduction of new functionalities for mobile apps, Pega Mobile Client 7 is removed in Pega Platform™ 8.5.
Upgrade impact
After an upgrade to Pega 8.5, you can no longer build mobile apps based on Pega Mobile Client 7, and existing apps based on Pega Mobile Client 7 no longer connect to Pega Platform. App developers can now configure mobile apps with Pega Mobile Client.
What steps are required to update the application to be compatible with this change?
Existing clients that upgrade to Pega 8.5 are automatically switched to Pega Mobile Client.
Limits on active data flow runs
Valid from Pega Version 8.5
You can now configure a maximum number of concurrent active data flow runs for a node type. Set limits to ensure that you do not run out of system resources and that you have a reasonable processing throughput. If a limit is reached, the system queues subsequent runs and waits for active runs to stop or finish before queued runs can be initiated, starting with the oldest.
For more information see, Limit the number of active runs in data flow services (8.5).
Upgrade impact
If you have many data flow runs active at the same time, you might notice that some of the runs are queued and waiting to be executed.
What steps are required to update the application to be compatible with this change?
You do not have to take any action. After the active runs stop or finish, the queued runs start automatically. The default limits are intended to protect your system resources, and you should not see a negative impact on the processing of data flows. However, if you want to allow a greater number of active data flow runs to be active at the same time, you can change the limits. For more information, see Limiting active data flow runs.
