Class mapped to CustomerData is incrementally indexed as expected
Resolved in Pega Version 8.6
When using a class which mapped to customerdata, instances that were added/updated were not automatically getting indexed unless a full reindex was performed. If the class mapping was changed from customerdata to pegadata then the incremental indexing was done. To resolve this, the UpdateProcessor class that resolves CustomerData to the correct database name has been updated to use PegaData. ConfigurationMapImpl contains the resolution mapping and a call is made to ConfigurationMapImpl to retrieve the correct database name.

Performance improvements for archiving and purging
Resolved in Pega Version 8.6
Archiving and purging jobs were not working in Prod. Investigation showed this was caused by the system timing out. To resolve this, improvements have been made to purging by batching the deletions and refactoring the Where condition to simplify the complex expression queries that determine the cases to be archived.

Unnecessary logging removed from startup
Resolved in Pega Version 8.6
The error "SettingMisusageFailure: Database is null" was repeatedly being logged following an update that consolidated error-handling logic for using a third-party custom jar file during the compiling process. This was an unnecessary message for this scenario as the database is often null at the early stages of startup, and SystemSettingsImpl has been updated to skip logging this error.

Locking and classmap improvements
Resolved in Pega Version 8.6
Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with class map performance and locking, and has been resolved by replacing the lock library with a newer version and refactoring the tableInformationMapImpl class to use a concurrent hashmap instead.

Process added to clear unneeded requestors from shared pools
Resolved in Pega Version 8.6
Shared service requestor pools were persistently showing a growing count of active requestors when a service was under heavy use, potentially leading to timeouts and exceptions. Investigation showed requestors were moving from active to inactive without updating the pool manager, causing service requestor pools to be held in an inconsistent state with active requestor pools not going down even after completion of service request. To resolve this, a job scheduler process has been added to stabilize the service requestor pools heuristically.

Deployment Manager rollback works for directed inheritance
Resolved in Pega Version 8.6
Rollback was not working correctly in Deployment Manager for history classes using directed inheritance. This was traced to a redundant check in AbstractHistoryPageKeeper that enforced the history pages pattern inherited from one of the base history classes, and this has now been removed.

Improved handling to ensure circumstanced rules skim is complete
Resolved in Pega Version 8.6
After performing a major rule skim, it was noticed that some of the circumstanced rules were not carried over to the higher version. The data was restored and a second skim was attempted. Once again, not all of the circumstanced rules were carried over; however, the results were different than in skim 1. This issue was traced to the circumstanced rule and base rule having the same pxCreateDateTime because they were processed with in a millisecond span. To resolve this, a 1ms explicit sleep has been added before processing each record.

Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.6
Unwanted optimization was automatically added to properties for the Application-Work-Casetype class created using the wizard in the App Studio. Attempts to remove the optimization did not work: the property advance tab was showing the optimized classes details even after deleting and recreating the property. When a property is optimized the system adds entries to pr_changelog for the list of classes it has optimized. When the property was deleted, the pr_changelog was not cleared. This was a missed usecase, and has been resolved by overriding the Cleanup activity at Rule-Obj-Property class to delete the pr_changelog entry associated with that if it is present.
