JMX logging added to upgrade diagnostics
Resolved in Pega Version 8.4.4
In order to improve diagnostic information, infoForced loggers have been added for debugging upgrade issues related to JMX calls to enable and disable rules creation.

Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.4.4
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.

Initialized entryName for light weight inventory instance
Resolved in Pega Version 8.4.4
When running deployment on a new pipeline created for the next minor version, once the deployment process got to the point of showing aged updates, the “view aged updates” came back as blank screen. Viewing the logs showed the aged update elements come back but were missing the pyName associated with them. Investigation showed that the system did not have support for setting the mEntryName for LightweightInventoryInstance objects. This has been resolved by adding a junit to ensure that getEntryName() doesn't return as null and should be equal to pzInsKey.

Hot Fix Manager updated to use installation order for schema import
Resolved in Pega Version 8.4.4
Schema changes were not being imported during the hot fix manager DL import process. Investigation showed this was due to hotfixes in the DL being iterated over from newest to oldest, causing older hotfixes to replace the value added to a map by the newer. To resolve this, the system has been updated to use hotfix install order, which considers selected and dependent hotfixes, rather than ordering newest to oldest. This ensures that newer table representations will override older rather than the other way around.

Updated upgrade handling for migrating work objects
Resolved in Pega Version 8.3.6
After upgrading from Pega 6.2 to 8.3, the work migrated work objects were missing SLAs due to missed entries in the assignment tables (PC_ASSIGN_WORKLIST/ PC_ASSIGN_WORKBASKET) . The SLA was firing, but the processing failed due to the fact the runtime could not resolve a 'AddHistoryPage' library function. In this case, multiple upgrades of the application dating back to Pega 4 resulted in the runtime context containing older ruleset versions in higher ruleset versions, hiding the underlying Pega 8 version of the rule. For releases prior to Pega 7.3, Rule-Application was stored in pr4_rule and will be migrated to pr4_rule_application during upgrades. However, since Context Upgrade is run before Optimize Newly Exposed Columns, the pyDependsOnName won't always be populated. To resolve this, the system will filter based on the value in the blob rather than the exposed column so there will be a value regardless of the upgrade-from version.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.3.6
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.

Hotfix hashmap cleanup improved
Resolved in Pega Version 8.1.7
A DL installation failed with an out-of-memory error. It was observed that many CacheEntry(VersionedJdbcJarRwader.java) hashmaps were being created to store the details for each hotfix but that were then never cleared. This has been resolved by adding the finally block in CodeImportProcessImpl.java class to call the shutdown method for proper cleanup. In addition, the default command line utility (prpcUtils) has been updated to use JVM settings of Xmx 4GB and capture a heap dump if an out-of-memory error is encountered. The auto-generated prconfig.xml has also been updated to leverage its minimal startup setting which will avoid loading the conclusion cache into memory.

Corrected requestor status flag for direct map
Resolved in Pega Version 8.1.7
Numerous "Unable to create requestor" alerts were logged. This was traced to an error in HttpAPI where after retrieving the requestor from the internal requestor map directly, the requestor creation status flag was not set properly. This caused last action to post that alert instead of the correct notice of "existing requestor retrieved". This has been resolved so the flag reflects the correct status.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.1.7
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.
