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.

Improved upgrade handling for tables using classes with property references
Resolved in Pega Version 8.1.7
After upgrade, some page property values were blank and exposed database columns did not contain the values. Investigation showed that the reference properties did not have context and hence column population was not able to determine their value. To resolve this, instead of doing column population for all the columns, the system will identify classes that have property references and that are being optimized as part of upgrade process and maintain a list of specific columns to update.

Enhancement added to modify URL encryption for load testing
Resolved in Pega Version 8.1.7
An enhancement has been added which allows conditionally modifying URL encryption for load testing. This uses the flag crypto/useportablecipherforurlencryption: if true, a portable hardcoded key is used to encrypt the URLs and if false, a dynamically generated key per thread/requestor is used to encrypt the URL.

Column population honors thread count of 1
Resolved in Pega Version 8.1.7
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.

Additional diagnostic logging added for ElasticSearch startup issues
Resolved in Pega Version 8.6.3
The PyIndexerState was stuck in Starting status during node initialization. This issue could occur if the filesystem became hung due to network level issue while scanning entries from /etc/mtab, resulting in a lock which was not released correctly. In order to better determine which node entry in a cluster may be responsible for the hang, an update has been made which will use a temporary virtual environment to repeat the part of the initialization phase responsible and generate additional logs for debugging. To activate this, the PegaSearch.Diagnostics logger must be set in DEBUG mode. This duplicated virtual initialization will not interrupt the normal initialization.

Updated replica management for search clusters
Resolved in Pega Version 8.6.3
When using a cluster with two Universal nodes in the cluster, a daily restart process where the second node was not started until the first was fully up resulted in Search initialization failing for the first node while becoming active on the second node. This was traced to the methods used in increasing and decreasing replicas. This has been resolved by revising the handling of ElasticSearch node lifecycle and replicas through a new option "Dindex.searchNodeCount " which includes a specification for the number of expected search nodes. If this option is not present, the old method will be used.

BIX Total Instance count matches manifest
Resolved in Pega Version 8.6.3
The BIX Manifest file was showing a count mismatch when the BIX Manifest and Extract files were shared with downstream teams, causing data to not be accepted by the downstream application. Investigation showed this occurred for an embedded page list property in the sequence that was missed and not considered. To resolve this, a DSS has been added: when BIX/generateAllEmptySubscriptForPageList is set to true, an empty subscript will be generated for the missed properties.

Restore point handling updated for absent pzpvstream column
Resolved in Pega Version 8.6.3
While executing the “get restore point” action for rollback, a PZPVSTREAMerror error occurred with the message "(util.HistoryCollectorDataModel) WARN|Rest|SystemManagement|v2|restorepoint - History collection for the table will be slow because it does not have all of the required columns". This was a missed use case for Robotics Automation not having a pzpvstream column for one of the tables; this has been corrected with a check to validate for pzpvstream column so the system will not seek history records if the pzpvstream column is not present.
