Improved timing for node tracing termination
Resolved in Pega Version 8.4.2
The tracer stopped tracing after tracing a certain number of events. This was due to communication timing issues for tracer events from one node to another node in a multi-node cluster environment, caused by the Tracer Client using the pzMaxEvent property which limited the maximum number of events fetched at a time to 200. Any leftover Events should have been fetched in the next request, but when the consuming node's service ended after the 200 events, the system removed the service requester entry from the distributed Map and disabled remote node tracing as part of cleanup of the service execution. To resolve this, an update has been made so the node tracing will not be terminated until the service execution ends and there are no more events to process.

Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.4.2
Out Of Memory exceptions due to Metaspace were observed on Web tier instances running with a max Metaspace size of 2GB. Investigation showed that in PRClassLoaderDB, mLoaderCache values were wrapped with a SoftReference. To resolve this, the Class Loader cache values will be wrapped with a WeakReference, allowing the cache to free memory when it is no longer needed. JVM options has also been added to switch types of References being used if there is a preference.

Resolved Agile Workbench video recording timeout
Resolved in Pega Version 8.4.2
Using the Record Video option thru Agile Workbench to create an Agile Studio item was either taking an excessively long time to finish or was hanging. Research showed that this scenario could arise when the input parameter value crossed more than 50 characters and triggered the interaction threshold for an alert, and has been resolved by updating the system so that query parameters with size more than 50 are not encoded and added to alert logs.

Thread context updated to supply steppage
Resolved in Pega Version 8.4.2
After upgrade, Server Startup was failing with the error "PEGA Rules Server not available". Investigation traced this to missing steppage information while invoking Rule-Utility-Function (from declare trigger when rule) during startup, which was caused by the thread calling the declare trigger, which was different from the thread running WhenRule, not being properly initialized during startup. To resolve this, the thread context has been changed to gThread, which contains the necessary steppage information.

Added handling for download of attachment with special characters
Resolved in Pega Version 8.4.2
If the name of an uploaded attachment contained a non-ascii character, the upload was successful but the downloaded file had the wrong name without any suffix. This was an issue on WAS or JBoss servers where filenames contained non-ascii characters, and the filename parameter in the content disposition header also contained these characters. To resolve this, the filename parameter in the content disposition header will be encoded as well along with the filename* parameter to handle non-ascii characters in the filename.

Added handling to resolve missing Pega 7 schema objects error on upgrade
Resolved in Pega Version 8.4.2
After upgrade, running post-upgrade activities reported the index table 'pr4_rule_vw_idx1' was listed as missing in the PEGA_RULES schema even though the index was present on pr4_vw_idx1. This was caused by formatting differences between Pega 7 and Pega 8.4 intended to make the columns unique. The pxObjClass column was removed from that index in 8.4 but this made it equivalent to the vw_updateDateTime index. As a result the code that performs the DDL upgrade ignored the new definition for pr4_rule_vw_idx1 because vw_updateDateTime already existed. It was safe to ignore this 'missing' index as the correct form exists as vw_updateDateTime, but to avoid issues the pXObjClass column has been added back to index pr4_rule_vw_idx1, but as a second column in the index.

Resolved sync error for offline workorder
Resolved in Pega Version 8.4.2
After logging on to the mobile app and then switching to off-line mode before opening a workorder from the worklist and processing the full workorder from end to end in offline mode, reconnecting resulted in the work order being moved to the [email protected] work basket with “Sync-Failed” status. Investigation showed that this was a caused by the DateTime properties being an empty string or null despite being created with a valid string. This was traced to the datetime conversion handling, and has been resolved.
