Property Rule Form refreshes after discarding changes
Resolved in Pega Version 8.6.2
After updating from Pega 8.2 to Pega 8.6 and migrating the properties, modifying any property rule and then discarding the change did not refresh the Property Rule Form. Investigation showed that the LOG-SYSTEM-PROPERTYOPTIMIZATION instance created during property optimization was not getting deleted when a property was deleted. As this was not getting deleted, the property was shown as optimized when adding the property back, causing confusion. This has been resolved by cleaning up the LOG-SYSTEM-PROPERTYOPTIMIZATION instance when the property is deleted and there is an optimization entry.

SSLContext created using protocol from REST connector rule form
Resolved in Pega Version 8.4.6
After upgrading to IBM websphere v9.0.5.6 or higher, API calls Like REST, Connect-HTTP etc were failing to connect to endpoints using TLSv1.2. Investigation showed that although the connector was configured to send TLSv1.2, the ClientHello handshake was triggered for TLSv1.3. Because the SSLContext was created with highest version supported by protocol in the WAS container, this has been resolved by modifying the code to create SSLContext based on the the protocol selected in the REST connector rule form. Additionally, please note that the Connect-HTTP connector has been deprecated and the Connect-REST capabilities in the platform should be used instead.

Ruleset Restoration Utility repaired
Resolved in Pega Version 8.4.6
Attempting to use the standard Ruleset Restoration utility after update was resulting in a "Status:fail Operator:Unauthenticated or not available Node:No ID available" error message. This was a missed use case for the refactoring done around importing rules, and was caused by the utility calling the deprecated Importable.isValidImport() method. This has been resolved by updating the import activity to restore its functionality.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.7
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

DSS partition count setting made backward compatible
Resolved in Pega Version 8.7
After upgrade, the DSS 'dsm/services/stream/pyTopicPartitionsCount' used to limit the number of partitions was no longer working and instead used the default value of 20. This has been corrected and made backwards compatible.

Check added to ensure read locks are released
Resolved in Pega Version 8.7
Read locks were not being properly released if a thread was holding a read lock and the system encountered an issue such as an out of memory condition. To resolve this, an update has been made to DeclarativePageDefinitionCacheImpl which will check whether a thread holds any read lock before trying to acquire a write lock, and if so release all the read locks held by that thread.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.7
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.
