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.

Handling added for comma value in FusionCharts XML
Resolved in Pega Version 8.3.6
After creating a Summary Report through the report browser and adding that report to the Dashboard, clicking on the report to drill down generated the error "Can't open the rule with the specified keys". Investigation showed that if a category or series in a Report Definition chart contained a comma, the drilldown would not work because of an incorrect pyclassname being passed. This was traced to the use of XML to configure the chart: the FusionCharts third-party library parses the link XML incorrectly and splits JS arguments at any comma. This was a missed use case for having a comma in the name, and has been resolved by adding encoding for the comma value in pzMultiSeriesData FusionCharts XML rule. Then this will be decoded in the drilldown JS APIs pzPega_chart_legacydrilldown and pega_report_summary.

Reports filtering made accessible
Resolved in Pega Version 8.3.6
In order to ensure accessibility, titles and helper texts have been added to the text fields and checkboxes that appear in the Edit Filter non-modal window after a 'Filtered By' value is selected on the My Reports page.

Summary Report collapsible sections made accessible
Resolved in Pega Version 8.3.6
In order to improve accessibility, the rules 'RRDataSummaryGeneration' and 'pzDisplayGroupNodeVertical' have been updated so the clickable expand icons in summary reports will append the value of the current group when setting the text "Click to expand or collapse". This will allow JAWS to uniquely identify exactly what will be expanded or collapsed.

BLOB decryption API updated for greater flexibility
Resolved in Pega Version 8.3.6
A BIX extraction issue occurred after the class had enabled BLOB Encryption. The errors indicated the BLOB had been persisted in an incorrect stage, causing the extraction of the single item to never complete even though some CSV file was created. This was traced to the API used to read the encrypted BLOB, DatabaseUtilsCommonImpl.getStreamBytes, which had the limitation of decrypting only when a Site-specific cipher existed. To resolve this, the system has been modified to use a different API which works for all encryption modes, PageDatabaseMapperImpl.getStreamBytes().
