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.

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.

Handling added for using virtual network interface for Stream Services startup
Resolved in Pega Version 8.6.3
After update, the restart of any node failed with the error "Unable to create DSM service DATA-DECISION-SERVICE-STREAMSERVER DEFAULT". This has been resolved by adding support for allowing stream service to start on the virtual network interface in cases where it was explicitly configured via the "cluster/hazelcast/interface".

Updated background refresh for off-screen worklist
Resolved in Pega Version 8.6.3
After update, performance impacts were seen on the field service mobile app. This was traced to Worklist refresh, and has been resolved by adding an update which will postpone the refresh when the worklist webview is in the background (not visible on the screen).

Check added to disable offset support for older versions of Oracle
Resolved in Pega Version 8.6.3
An ORA-00933 error was generated after upgrading from Pega 7.1 to Pega 8.5. This was traced to a conflict between Oracle 11g and the Pega 8.5 platform related to an OFFSET statement being added to a query for a version of Oracle that doesn't support it. The preferred solution is to upgrade Oracle to address this, but in order to support backwards compatibility a check has been added which will disable offset support in Oracle if productversion <=11.

Database Transaction Log update overflow resolved
Resolved in Pega Version 8.6.3
When automatic.resume=false was encountered uring an update, cleaning up the existing codeset from previous updates ended up filling up the database transaction logs and caused the update to fail. This has been resolved by updating the process of clearing the codeset so it doesn't overflow the transaction log.
