Upgraded selected third-party JAR files to support Pega Platform functionalities

Valid from Pega Version 8.6

Pega Platform™ 8.6 now provides upgraded versions of the JAR files that support various functionalities within the Platform, such as generating documents or PPTX files.

Upgrade impact

If you have custom implementations and use any classes from the upgraded JAR files directly in your code or through JAR APIs, after your upgrade to Pega Platform 8.6, your application might experience unexpected run-time behavior if the upgraded JAR version lacks any elements from the previous version. For example, custom implementations can typically include activities, functions, or non-autogenerated sections. Unexpected run-time behavior might also occur when you use a third-party library that has dependencies on the upgraded JAR files. If you use only default Pega Platform functionalities without any customizations, the JAR files continue to work correctly without any additional actions.

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

If you have any JAR customizations, ensure that you test the upgraded JAR files for compatibility and upgrade impact. The following table lists the upgraded JAR files that might impact your application:

Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6

Valid from Pega Version 8.6

Pega Infinity™ uses Hazelcast distributed clustering technology to share data and send events between server nodes. Beginning in Pega Infinity release 8.6, Pega Infinity supports Hazelcast 4.x.
 
Note: Note: Because Hazelcast 3.x is in extended support, upgrade to Hazelcast 4.x before the extended support period for Hazelcast 3.x ends.

Upgrade impact statement

On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.

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

Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.

For instructions about upgrading to Hazelcast 4.x, see one of the following topics:

Improved indexing of StringList and StringGroup property types

Valid from Pega Version 8.6

Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.

Upgrade impact

After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed. 

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

On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.

For more information, see Indexing class data.

 

Rules Assembly cache is deprecated

Valid from Pega Version 7.3.1

Rules Assembly (RA) cache and custom settings for its corresponding fua/assemblyCacheModeprconfig.xml file setting are deprecated because they are obsolete. A warning is logged at startup if a custom (non-default) value is specified for fua/assemblyCacheMode in the prconfig.xml file. The functional behavior of the system is not affected.

Use of PegaRULES_Extract_Marker.txt to delete cache is deprecated

Valid from Pega Version 7.3.1

The PegaRULES_Extract_Marker.txt file is deprecated. The system uses the presence or absence of the PegaRULES_Extract_Market.txt file to determine at startup whether to delete the static content, service export, and lookup list file system-based caches. In the rare situation that you need to delete these caches manually, use the System Management Application (SMA) ETier Static Content Management page. Using SMA does not require restarting the node.
