Published Release Notes

Guardrails compliance score

The Application Guardrails landing page has been enhanced to help you build more guardrail-compliant applications. Increase transparency and accountability on your projects by responding to the following compliance score metrics:

• A weighted compliance score (0-100) based on warnings, severity, and justification
• A percentage of compliant rules in your application
• Total number of rules in your application
• Total number of rules in your application with warnings (justified and unjustified)

Additional metrics include alert and interaction count trends over the last four weeks.

For more information, see Guardrails compliance score.

EAR support for JBoss EAP 6

PRPC deployment in JBoss EAP 6 as an EAR archive is now supported. 

If you need to deploy the JBoss EAR file, go to My Support Portal and submit a Support Request. GCS can assist you with the procedure.

Directed inheritance view in Application Explorer

You can now specify which inheritance model is used to populate classes in the Application Explorer. From the top level menu, use the “Explorer Inheritance” option to choose between:

• Pattern: only display class names whose prefix matches the root node class name.
• Directed: first display classes that explicitly name the root node as the parent class; then display classes with pattern inheritance.

By default, the Application Explorer loads using Pattern inheritance. 

Small distribution kit

A new “small” release distribution format for Maintenance Levels (ML) is now available, designed to significantly increase adoption via: 

• Minimal package size and faster download time
• Minimal install time via tactical changes to the upgrade implementation and process

This kit contains streamlined installers (both UI and command-line installers) and specialized error handling for ML updates (for example, a “small” kit will only work if an existing version of the same release is already installed). 

The kit assembly has also been automated, which includes the construction of a PRPC_Rules.jar archive containing cumulative rules since the GA release. 

A “small” kit will work for any prior ML release within a major release (for example, the “small” ML5 distribution kit will update any customer on 7.1 ML1 through 7.1 ML4).

Improved data page performance

Improvements have been made with queueing and processing of asynchronously-loaded data pages to reduce the number of calls to the database and avoid generating performance problems because of unneeded asynchronous requests.

Save Application Explorer filter selections

Application scoping control selections made in the Application Explorer are now persisted between sessions. These preferences are stored in an operator record on an access group level. If you delete (and later re-add) an access group on your operator form, the application scoping control defaults to all layers selected:

External access control DASS

A new Dynamic Admin System Setting (DASS) controls the Designer Studio's access to external systems, specifically the PDN RSS feed found on the home page.

By default, Pega-Desktop.AllowAccessToExternalSystem is set to TRUE. Update this setting to FALSE to hide the PDN RSS feed and ensure that no RSS fetch is performed.

Restricted SMA access

System Management Application (SMA) remote connections are not supported on JBoss EAP 6.x. This means SMA users may only monitor locally connected systems. Ensure that the "Local JVM Connection..." option is selected when configuring PRPC nodes:

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.

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.
