Performance improvements for sites with a large number of tables
Resolved in Pega Version 8.3.6
Performance impacts were seen when there were a very large number of tables in the database and the cluster/node persistence jobs were running. This was traced to the volume of metadata / schema introspection queries fired from the pyPersistNodeState and pyPersistClusterState jobs along with the Classmap cache invalidation / lookup queries, and has been resolved by improving the code to avoid database introspection when the current number of tables is greater than a maximum value.

Optimizing helper class enhanced to handle external databases
Resolved in Pega Version 8.3.6
Running a BIX extract that included a manifest for a target database was resulting in a null pointer exception for the manifest extraction. Attempting to generate the DDL for the manifest table also failed. This was traced to an issue with the helper class using a hardcoded default database for forming the queries, causing it to ignore the DB config/DADN/prconfig for the Oracle database and form a query using the PegaRules' database credentials. This only occurred when trying to do external database operations on a different DB platform; Oracle PegaRules worked as expected with an Oracle external DB and Postgres Pegarules worked with a Postgres external DB, but mixing Postgres PegaRules and an Oracle external DB would result in the null pointer error. To resolve this, the helper class has been enhanced to work with external databases by passing the database name as a parameter so it will properly calculate the query based on the type of target. The default for 'database/oracle/allowOptimization' is set to false: additional database privileges must be added or some configurations must be updated to provide the information needed in lieu of the privileges before making use of these optimizations. In addition, an error in the name of the class has also been corrected and is now available as PerformanceHelper rather than the previous "PerformaneHelper".

Locking added to avoid null pointer error for auto-populate property
Resolved in Pega Version 8.3.6
After configuring the auto populate property "OrgProduct" which referred to a data page, the system experiencing heavy load led to the property not getting properly initialized. This resulted in a WrongModeException and NullPointerException. To resolve this, the system has been updated to lock the requestor when Queue Processors execute their activity. This will prevent race conditions and concurrent modifications if other threads are accessing the same requestor.

Decision table query performance improvements
Resolved in Pega Version 8.3.6
Severe latency was seen after upgrade, and it was not possible to save business rule changes. This was traced to an issue with the decision rule being treated as a custom rule, and has been resolved by inserting a check. In addition, optimization has been added for queries on the pr_sys_decchg table.

Resolved PRQueueLockException
Resolved in Pega Version 8.3.6
A Class Queue not found exception resulted when an SLA was deleted on the same transaction where it was created when deferred save was used. This was an inadvertent side effect of work done on the QueueManager implementation to invalidate previously deferred operations for item and schedule removal, and has been resolved by clearing the processing state for PRQueueLockException when an item reservation fails.

Transient property passivation handling improved
Resolved in Pega Version 8.2.6
Frequent "com.pega.pegarules.pub.PRRuntimeException" errors were seen in the production log file while working on the WO. This was traced to corruption in the blob caused by transient properties during passivation. To resolve this, corrections have been made to the handling for the transient property entries in the blob.

Enhancements added for using AWS file repositories
Resolved in Pega Version 8.2.6
Enhancements have been added to improve the use of AWS file storage: - Logging for AWS SDK connection metrics can be activated on a per-repository basis, either through the ruleform or through the DSS `storage/class/:/enableMetrics`. - INFO logging can be enabled on PegaAWSSDKMetricReporter to periodically output averages of recorded metrics for all registered S3 repositories with metric collection enabled, or INFO logging can be enabled on PegaAWSRequestMetricCollector to output recorded metrics on every client call for all registered S3 repositories with metric collection enabled. - The interval at which PegaAWSSDKMetricReporter logs metrics at can be configured with the DASS `storage/AWSSDK/metricReportingInterval`. This DASS is a system-wide setting, and not a per-repository setting. The default reporting interval is 90 seconds, and metric collection is disabled on all repositories by default.

Added support for Helper Text Question Mark with visibility condition
Resolved in Pega Version 8.2.6
The Helper Text Question Mark was not displaying if the control was configured with "Help icon with overlay on hover" combined with a visibility condition. This was a missed use case, and the expression visibility support for controls.changes have now been added in the pzpega_ui_DLCellTemplate.js file.

Sorting on Grid works with declare expression property
Resolved in Pega Version 8.2.6
If a property with a declare expression was used in a column, the sorting on that column was not working. This was traced to reference errors when Grid used the engine API pega.sortPageList to sort the page list / data page, and has been corrected.
