Removed duplicate Set-Cookie Secure Keyword
Resolved in Pega Version 8.6.1
Checking the headers of the login page showed the Cookie Pega-AAT duplicated the Secure keyword. This was traced to the PegaAATCookieWrapper extending the CookieWrapper class and causing the secure flag to be set in both the classes. This did not have a functional impact, but the secure flag set has been removed from the PegaAATCookieWrapper class to avoid duplication.

Resolved classcast exception with assembled HTML controls
Resolved in Pega Version 8.6.1
A classcast exception was being generated on login. Investigation showed the Static Assembler was unexpectedly using a different Assembler to assemble the Html control rule. Standard behavior is that StreamBuilderAssembler assembles controls of type StreamBuilder and ControlAssemblerForVTable assembles controls of type ControlBuilder. In this case, static assembly for HTML controls using VTable was performed using StreamBuilderAssembler, causing a classcast exception when using VTable because the instance of the generated.html class was incorrectly inheriting from StreamBuilder (the parent class of ControlBuilder) instead of ControlBuilder which is the specified interface in the generated.html Java code. This has been resolved by updating the system to skip rules of type 'Rule-HTML-Property'(control) during Static Assembly.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.6.1
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

InsID will be derived from handle if null after update
Resolved in Pega Version 8.6.1
Updating from Pega 7.2.x to Pega 8.4.x failed with a null pointer exception in the “Upgrade Context” target. This was traced to a rule where the pxInsID was null. To resolve this, an update has been made to derive the InsID from handle when needed.

Handling added for multi-node concurrent access to conclusions
Resolved in Pega Version 8.6.1
A proposition update was triggered and heap memory jumped up and a thread dump was generated. A Pega0004 error was also generated at the same time. Investigation showed that many queries were getting fired on pr4_rule_sysgen table in a multi-node environment during RAP import. This caused database contention as more than 80 nodes were trying to load conclusions simultaneously. To resolve this, an update has been made to run an agent periodically to save conclusions into the database. This agent is configured to not run on multiple nodes simultaneously, which will avoid database contention issues from conclusions.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.6.1
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.

Links to specifications persist appropriately
Resolved in Pega Version 8.6.1
When linking Rules to Specifications, check-ins of some unrelated rules deleted the link. Investigation showed the deletion happened in the pzHandleLinksPostCheckIn activity, and was caused by an empty parameter page name that caused pcInsKey to not have a value, so all links returned by "Obj-Browse" were later deleted. To resolve this, an update has been made to insure the "Pass current parameter page" option in step 2 of the Connect REST PostCheckIn activity is enabled so that the downstream activity pzHandleLinksPostCheckIn behaves as expected.

Delayed JS/DF initialization failures will trigger alert
Resolved in Pega Version 8.6.1
In order to ensure better cluster monitoring, a PEGA0102 alert has been added for job registration failure that will be triggered if there are startup issues. The logging will include the JOB_NAME for improved troubleshooting.

Queue Processor threads explicitly cleared before new interaction
Resolved in Pega Version 8.6.1
Queue Processor was not clearing already evaluated freshness caches before running an activity, potentially causing a stale data page to be processed. This has been resolved by explicitly clearing the thread on a new interaction by invoking ((IPRThread) thread).clearOnNewInteraction.
