Classmap will not be rebuilt if there are no class changes
Resolved in Pega Version 8.7
The get MBA service was not working as expected after update. This was traced to a Strategy FUA contention issue with ClassmapImpl: each time the System Pulse processed a CACHE type, it resulted in the ClassMap being rebuilt even if a Class was not added or deleted. To resolve the issue, a condition check has been added on the two places in ProcesChangesFromPulse.processChanges() that call DatabaseImp.noteConfigChangesInClassMap(). If the size of the list is 0, there is no need to rebuild.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

ServicePackage thread handling improvements
Resolved in Pega Version 8.7
Work recently done to improve the release of requestor pool threads for the ServicePackage has been further enhanced by adding an explicit status notification to the thread waiting for Data Pages to be loaded in background and added support for the use case of a missing object handler. This also resolves a 504 Gateway Time-out error intermittently seen while trying to open the URL of the Pega application.

DSS added to control DADT purge
Resolved in Pega Version 8.7
Thread dumps and service restarts were seen when Decision Engine data nodes were working with a very large number of tables. This has been resolved by adding a DSS as part of the CDH layer which will skip CDH DADT that contains pattern DATA_BATCHOUT, for instance "DATA-ADMIN-DB-TABLE DATA-BATCHOUTPR469001" to prevent the deletion causing full cache invalidation of the table information map. With this DSS set to true, when the purge agent runs and deletes the DADT, class cache should no longer be invalidated. With the DSS missing or set to a value other than true, the class cache invalidation will still occur.

Handling updated for validating properties with a FieldValue
Resolved in Pega Version 8.7
Running a report which included a property calculated by a Declare Expression generated an excessive number of log messages indicating "Error occurred while executing forward chaining on page 'pyReportContentPage.pxResults". Degraded system performance, stack overflow, and other similar issues were seen. This was traced to an infinite loop that resulted from a missed use case for a Report Definition with a Target property of a Declare Expression with FieldValue, and has been resolved by disabling autochain while validating properties with a FieldValue.

MQ jar handling updated to resolve initialization error
Resolved in Pega Version 8.7
After update, errors were seen indicating a NoClassDefFoundError relating to initializing com.ibm.mq.jms.MQQueue. This was traced to a difference in the handling of imported MQ jars, and has been resolved.

New or updated operators properly updated on other nodes
Resolved in Pega Version 8.7
Newly imported or updated operators were not getting properly pulsed to other nodes. This was traced to operator pages being cached while the system pulse for 'Data-Admin-Operator-ID' was not permitted on the allow list, and has been resolved.

Added handling for Create Source and Target properties of Date
Resolved in Pega Version 8.7
A report definition was not displaying results after update, and a stack overflow was reported. This was a missed use case for Create Source and Target properties of Date, and has been resolved by adding a boolean flag to avoid autochain during validations when data type is Date.

Parameter handling updated for GetRepositoryFolderName
Resolved in Pega Version 8.7
An UnresolvedAssemblyError was generated with an Unauthenticated Thread exception after opening the declare expression Embed-Application-StorageProvider pyFolder and performing a private edit. This error was traced to the Rule-Utility-Function call "pxGetRepositoryFolderName()", which was expecting a parameter "tools" which was not being passed from the declare expression rule. To resolve this, the pyFolder and pyFoldeIf declare expressions and pzsetContentStorage have been modified to pass 'tools' as a parameter to pxGetRepositoryFolderName.

Parameter handling updated for cloned environment
Resolved in Pega Version 8.7
The Editable data page parameters were not getting set in a cloned environment. This has been resolved by adding code to detect the use case ('append and map to action' with 'a new page' relation) and let it fallback to legacy code generation.
