Published Release Notes

Naming pattern changed for file data sets

File data sets are used to import from and export data to a file repository. In case of data export, prior to version 8.6.3, the first file exported had the same file name that was provided by the user in the data set, and any subsequent file exported to the repository had a unique identifier appended to it. Starting in Pega Platform version 8.6.3, each file has a unique identifier, automatically generated based on the data flow node, thread ID, and timestamp.

Upgrade impact

If your process to consume output files expects files with a specific name, it may not be able to process the resulting files correctly.

What steps are required to update the application to be compatible with this change?

If you have configured the process before updating to Pega Platform version 8.6.3, but the exported files are no longer recognized by downstream processing logic after the upgrade, ensure that the downstream tool is configured to recognize the files by a pattern rather than the full name. For example, when referring to files exported to the repository, use the * character to indicate a pattern instead of using the full file name. For example, use Export*.csv to refer to the files.

Change logic does not work in Report Editor

The Report Editor​ change logic button does not work. As a workaround, use the rule form to change the logic.

Tomcat log files moved to work directory

For Tomcat application server users, the default path for PRPC logs has been changed to the "work" directory for Catalina. For example:

<tomcat>\work\Catalina\localhost\prweb

This directory can be cleaned up during administration. To avoid loss of files, you can redirect logging to a different directory after installation:

1. Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
2. Open the prlogging.xml file.
3. Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
4. Update the FileNamePattern values to point to the new directory.

For more details, refer to the “Change the default path to PRPC logs” section in the Tomcat installation guide for your database.

Slow WebSphere performance on Mac platforms

Use the following JVM setting to improve WebSphere performance on Mac platforms:

-Djava.net.preferIPv4Stack=true

Split schema systems require additional privileges

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.

Node description cannot match application server node name

A node's Short Description should not be the same value as the application server node name. If the node's Short Description is changed to be the same value as the application server node name, then the node description is automatically changed back to the original value after a system restart.

Support for encrypted traffic in a cluster

The Pega 7 Platform includes the Ignite platform, which supports encryption for intra-cluster communications. You can now configure encryption for intra-cluster traffic for compliance with regulatory or organizational security requirements.

For more information, see Enabling encrypted traffic between nodes.

Deploy revisions directly in target environments

As a revision manager, you can now directly deploy or migrate completed revisions to multiple Pega 7 Platform environments that were configured as targets by the system architect. The revision management process is faster because you do not need to package a revision as a JAR file, and then manually import that file to the Pega 7 Platform. Additionally, this solution gives business users more control over application rulesets and enables them to act more independently.

For more information, see Direct deployment of revisions.

Batch database processing improvements

Batch database processing has been enhanced to ensure that a constraint violation does not occur when you save transactions to a table with a foreign key dependency. Because batch processing changes the order of save operations, it is disabled for transactions with foreign key dependencies. Disabling batch processing ensures that a record with a foreign key dependency on another record will not be written before the record on which it is dependent.

For more information about how batch database processing works and how to enable and disable it, see Batch processing during database write operations.

Operator presence record tracks disconnected status of operators

The state attribute in the operator presence record now tracks the operator connection status of DISCONNECTED, in addition to tracking the operator connection status of ACTIVE, AWAY, or OFFLINE. Operators are disconnected if their browser crashes, if they close a browser session without logging out of the system, or if the network connection is down. The DISCONNECTED status helps prevent work from being routed to operators who are not online or not available.

When the operator restores the browser session or the network connection is restored, the Pega^® Platform updates the operator connection status to ACTIVE.

For more information, see Tracking the online presence of operators.
