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.

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.

Hazelcast upgraded to resolve node startup issue
Resolved in Pega Version 8.1.8
Post data upgrade, the ADM tier failed to start and the error "java.lang.IllegalStateException: Node failed to start!" appeared. This was traced to a dormant bug in Hazelcast 3.11 that caused starting nodes to fail when the Hazelcast master node was shutting down, which was exposed by recent Pega changes made to enable parallel restarts of nodes in Cloud environments. Hazelcast delivered a fix for the parallel restart problem and the hotfixed jar has been merged into the platform.

Resolved Oracle thread deadlock for Merge SQL
Resolved in Pega Version 8.1.8
After starting a large cluster and running it for a couple of days, Oracle Deadlocks started to appear due to resource contention during MERGE SQL execution on the PR_INDEX_REFERENCE database table. The "ORA-00060: deadlock detected while waiting for resource" ERROR occur continuously every 10 minutes during the "MasterForNewAgents" Daemon run. All JVMs are impacted by the ERROR/Deadlock. Investigation showed that even though the identified / problematic Data-Agent_queue instances were disabled for PegaAESRemote, the MERGE SQLs continued to fire. To resolve this, an update has been made so the system will skip the copy of rule reference property from RAQ, while creating DAQ.
