Batching now enabled when using IH Summary shape in substrategies
Resolved in Pega Version 8.2.4
Batching was not being enabled when using IH Summary shape in substrategies. This was traced to the IH_SUMMARY_CACHE field not automatically being passed to sub-strategies, and has been corrected.

Threads will be updated to maintain assembly context when using Static Assembler
Resolved in Pega Version 8.2.4
When running the Static Assembler utility from UI, the assembler process completed successfully but the PegaRULES.log was flooded with the FATAL exception "Usage error - next Executable not based on current". This error was generated from com.pega.pegarules.session.internal.mgmt.Executable constructor, and indicated an issue with the thread context being different from the assembly context. To resolve this, the system has been modified to update the context of thread to what is expected as assembly context.

Hazelcast will be used to determine node presence
Resolved in Pega Version 8.5.2
When calling logoff from the end user portal, sporadic PresenceStandardLifeCycleListener exceptions were seen during high load periods. This was traced to changes made in the Service Discovery behavior: when there is an issue with the node and heartbeats are missed, the node goes to Safe Mode. This caused the topology to change and trigger clearing off presence sessions, but the node still received service requests and this issue was seen. To resolve this, an updated has been made so the system will rely on the Hazelcast listener instead of service discovery to determine whether a node has left.

Assistance and diagnostics added for issue with opening imported 'when'
Resolved in Pega Version 8.4.6
After update, attempting to open rules that were developed on lower environments and then imported resulted in unknown errors. A workaround has been added to skip and log any corrupted property that might be interfering with the rule opening: enable Skip-Corrupt-Property to put this in place. To improve diagnostics, the new logger NBA-WME-DEBUG has been added. If the error continues after using Skip-Corrupt-Property, Skip-Corrupt-Property should be disabled and NBA-WME-DEBUG should be enabled and kept active until the issue occurs again.

Added workaround to handle HiddenPropertiesToIgnore when a page is in Read Only mode
Resolved in Pega Version 8.2.4
A 'WrongModeException' was generated while trying to use the Data Transform pxHiddenPropertiesToIgnore to remove system properties from page. When the Datapage was set to Editable/Savable mode, the Activity ran without an error and executed the Data transform. When the Datapage was in Read only mode, the error occurred. This was traced to a process that previously was allowed to set a page to an empty string, but which was removed during recent work. To resolve this, four instances of pxHiddenPropertiesToIgnore that included Single Page Value properties have been updated by moving them to the bottom of the Data Page and changing them to an "Update Page" from a "Set".

SQL queries modified to use qualified table references
Resolved in Pega Version 8.4.6
Portal launch in the development environment was taking an excessive amount of time, as were some standard reports. The PurgeAssemplyDatabaseCache agent activity also generated an error regarding "(internal.cache.RAPurge) ERROR - Purge, unexpected error in removeOldAppCentricCacheData". These issues were traced to SQL queries that contained pr_sys_app_hierarchy_flat without a schema qualifier, and have been resolved by changing to class qualified table references.

Parent case lock properly released when child case is resolved
Resolved in Pega Version 8.2.4
After creating Parent-Child casetypes with default locking where the child case had the “Allow access to parent” check box checked, the temporary lock acquired on the parent during resolution of the child case was not released afterwards. If “Allow access to parent” was not checked, then the locks were released on both the parent and the child. This was traced to a combination of parameters used by the openIfStale() API where aUnlockOnCommit could be set to false despite the provided locking strategy expecting it to be true, as well as honoring UnlockOnCommit when maintainLockingStrategy is false. To resolve this, the system has been updated to always check whether the lock is available in the map already and if it is, then set unlockonCommit to true. Otherwise, under all cases, honor the passed-in unlockOnCommit value.

Force order added to inner join when running a Rules Resolution filter
Resolved in Pega Version 8.2.4
After upgrade, D_getResolvedWorkStatuses was not loading properly due to a Report Definition that used a Filter by Rule Resolution option timing out on the SQL Server. When the Filter by Rule Resolution option is selected in Report Definition, it will generate a rule resolution query with an inner join which can cause a time out on the SQL Server while it tries to find out the join order for tables with multiple joins. To resolve this, the SQL server will provide a Force order, merge inner join hint option by way of an added DSS reporting/useForceOrderHint. Additionally, reporting/useMergeHintForRRquery should be set on Pega-Reporting to set things up for using the Merge Inner join hint in the query.

Data-Summary reports default will not use the rule resolved setting
Resolved in Pega Version 8.5.2
An intermittent issue was seen where a query could become stuck for ~2 hours in the database. This has been resolved by setting the default for Data-Summary reports to not use the rule resolved setting.
