Published Release Notes

DB2-LUW database logfile size increase

To avoid running out of logfile space due to large transaction sets during the rule base load of a Pega 7.1.x install, upgrade, or maintenance level update, systems supported by a DB2-LUW database platform should increase the LOGFILSIZ parameter to at least 4096 pages from the default size of 1000 pages.

After the size has been increased, restart the database to ensure that the new setting is loaded into the database correctly.

Text Input control number type does not validate

When a Text Input control type is set to "Number" in the Presentation tab:

• Validation does not trigger and the field is blanked out when a user submits the form.
• If a value other than a number is entered, the browser sends an empty value, and the value is not validated.
• In the Clipboard, the field value displays as empty.
• If the field is required, the validation displays.

This issue occurs when using both the Chrome and Safari web browsers, and is a result of browser behavior for the HTML5 type=“number”. To fix this issue when using these browsers, do not use the "Number" type in Presentation tab of a Text Input control. Instead, the type should be set to "Text".

Need to run script before updating Multitenant systems

When updating or upgrading a Multitenant system from Pega 7.1.5 or 7.1.6 to Pega 7.1.7, if that system uses either an Oracle or a PostgreSQL database, you may encounter the error:

“Table must be empty to add column.”

The Multitenant architecture requires an additional column on a number of the PRPC database tables (“pzTenantID”). In Pega 7.1.7, two additional PRPC tables were tenant-qualified: pc_schedule_task and pr_index_schedule_task. The Multitenant column is added to these tables by the update/upgrade process. However, Oracle and PostgreSQL do not allow the addition of a non-null column to an existing table unless the table is empty, so updating or upgrading systems on those databases displays the error detailed above.

To avoid this error, before beginning the update or upgrade, it is necessary to run a script:

• Oracle — OracleMTupgrade.sql
• PostgreSQL — PostgresMTupgrade.sql

For updates, these scripts are located in the /scripts/ddl directory.

For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.

Unclear error message when saving shared class instance in tenant layer

If you attempt to save a shared class instance from the tenant layer, Pega 7 displays this message:

This record has x errors. Save Failed: There was a problem saving an instance of class: Error Code: <none> SQL State: <none> Message: <none>

You cannot save a shared instance from the tenant layer if that instance cannot be overridden.

Data page unit test case setup and cleanup

You can now use one or more data pages, data transforms, or activities to set up a clipboard page with the appropriate properties before you run a data page unit test case. You can also use activities to create any required test data, such as work or data objects.

After you run a data page unit test case, the data pages that were used to set up the test environment are automatically removed. You can now also apply additional data transforms or activities to clean up the clipboard.

For more information, see Setup and cleanup of data page unit test cases.

New assertions for data page unit test cases

You can now configure the following assertions for data page unit test cases:

• Result count assertions for page lists, page groups, value lists, and value groups
• Unordered list and ordered list assertions for page lists

The Pega 7 Platform now supports these assertions in addition to expected run-time assertions for the data page and property assertions for any property type.

For more information, see Data page unit test case assertions.

End of support for Microsoft Internet Explorer 9 in Pega 7.2.1

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 9, Pega 7.2.1 will not support Internet Explorer 9. You should not upgrade to Pega 7.2.1 if you are still using Internet Explorer 9. Otherwise, upgrade to Microsoft Internet Explorer 10 or later, or use Google Chrome, Apple Safari, or Mozilla Firefox, which support certain HTML5 and CSS3 standards not supported in Internet Explorer 9.

For more information about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

New options to manage proposition validity

Manage your decisioning strategy more effectively with proposition validity settings. You can now set your propositions as always active, inactive, or active only within a defined time period. Setting a validity period for your propositions helps you to plan your strategy and automatically activate or deactivate propositions in the future.

For more information, see Proposition validity.

Ability to import data into a Pega Cloud database

You can export a custom Pega 7 Platform database table into a CSV file and import it into a Pega Cloud database or other Pega 7 Platform database by using the Data Upload utility. This utility is available only for Postgres databases and tables that do not contain BLOB columns. This utility is useful, for example, for updating a product catalog that is used in a Pega Cloud application.

For more information, see Importing data into a Pega Cloud database.

Ability to schedule schema updates for Pega Cloud

You can schedule BLOB size and table statistic updates to database schemas to run automatically by using agents. Scheduling schema updates is useful for performance monitoring and tuning in the Pega Cloud. This feature is available only for customers who use a Postgres database.

There is an agent for updating the average and maximum BLOB sizes, and an agent for updating table statistics. Each agent can be configured separately for each schema. You can configure whether to schedule the agent to run daily or weekly. You can deactivate a running schedule on the Schema Tools landing page by clicking Designer Studio > System > Database > Schema Tools. From the Schema Tools landing page, you can configure more complex scheduling on the Edit Agent Schedule landing page. In addition, you can configure these agents by using Dynamic Data System Settings.

For more information, see Scheduling schema updates.
