Corrected caching sync for proposition filter
Resolved in Pega Version 8.4.2
Unit testing or a manual run of the generated strategy through next best designer was not giving the result, but instead was throwing a stale thread error. Investigation showed that the PegaAPI reference was cached in proposition filter at first execution and the filter was trying to use same reference for other further executions. This has been resolved by ensuring the cached reference is properly synced.

Key Value Store handling revised for greater backwards compatibility
Resolved in Pega Version 8.7
Previous optimization work done to reduce the size of the "nm" field when the hierarchy string is empty resulted in some Key Value Store records not being read from older systems during update. This has been corrected.

Hazelcast remote execution not called from synchronized context
Resolved in Pega Version 8.7
After navigating to the Admin Studio portal to view the nodes, the portal was temporarily freezing. Investigation of the thread dump revealed this was caused by a DDS pulse sending a remote execution call to all nodes to update logger settings even though the site was not using DDS. This has been resolved by updating the system to avoid calling Hazelcast remote execution from a synchronized context.

Scenario Planner performance improvements
Resolved in Pega Version 8.7
Scenario planner runs were causing out of memory errors on the dataflow nodes. To resolve this, updates have been made to improve performance. Only relevant information will be kept for decision funnel simulations out of SR pages, the memory footprint of data structures used to aggregate and rollup counts has been reduced, and temporary objects will be released as soon as they are not needed anymore.

Added handling for DSM Services stuck in leaving status after database outage
Resolved in Pega Version 8.7
During a database outage, the heartbeat would fail and DSM services would eventually try to enter safe mode and stop. As the first step they would try to change the state to LEAVING, but because the database was down saving the LEAVING state failed and the exception was not handled correctly. This resulted in the rest of the stop operation logic not being executed and the service being stuck in LEAVING. To resolve this, an update has been made to ensure the service goes to LEAVING_FAILED if anything fails during the stop operation including when setting state to LEAVING_FAILED. The state LEAVING_FAILED will get flushed to the database eventually when it comes back up. This will allow the aggregation service to start from the LEAVING_FAILED state and recover by itself after a database outage.

Predictive model snapshot generation updated for Java 11
Resolved in Pega Version 8.7
While the Simulation data export case type was executed as expected, the predictive stages showed zero records processed. This was traced to instances running on Java 11 which caused an issue with the snapshot process. This did not affect learning, but visualization and reporting were not working in Prediction studio. To resolve this, an update has been made to the snapshotID for Java 11 compatibility which will generate a random UUID instead of using a seed.

Report Definition replaced with a data set for training the data and build model
Resolved in Pega Version 8.4.2
An issue with training the data and build model via an email or chat channel was traced in an exception in logs indicating the inability to execute a Report Definition. This can happen when UDF are removed/disabled in the database or in environments where functions are not allowed to read the blob for performance reasons. To resolve this, the Report Definition has been replaced with a data set.

D_ProjectList updated to resolve defined databases error
Resolved in Pega Version 8.7
After update, an API error for D_ProjectList indicating "No databases defined" was seen when trying to load decision and templates for the first time. The error did not reoccur after the initial save. This was has been resolved by updating the handling for loading the properties file during class loading. The error has also been changed to an exception.

IH Summaries correctly loads aggregated count
Resolved in Pega Version 8.4.2
After the IH Aggregated DataFlow has processed more than 34 million records from an Oracle database, the IH Fact table contained only ~120,000 records. Running a browse on the pxInteractionHistory DS resulted in an infinite loop. Investigation showed that this was caused by the handling of Oracle timestamps: using Pega DateTime in query parameters generated Oracle DATE instead of TIMESTAMP, causing all query parameters to be rounded to the second and interfering with the IH pre-aggregation. This has been resolved by updating the handling.
