Permissions added to handle Openshift installer image
Resolved in Pega Version 8.7
When running the install process on an Openshift test cluster, the process failed with a permissions error while attempting to download the postgresql-42.2.12.jar. This has been resolved by ensuring the root group can write to the distribution files.

Queue Processor threads explicitly cleared before new interaction
Resolved in Pega Version 8.7
Queue Processor was not clearing already evaluated freshness caches before running an activity, potentially causing a stale data page to be processed. This has been resolved by explicitly clearing the thread on a new interaction by invoking ((IPRThread) thread).clearOnNewInteraction.

Admin Studio will consider cluster protocol when returning listener status
Resolved in Pega Version 8.7
When using a few nodes in standalone mode for BIX extract combined with server nodes using Hazelcast, opening the admin studio pages with service discovery caused an error to be thrown. This was traced to the system writing an entry to pr_sys_statusnodes table as an embedded node whenever a BIX extract was triggered, causing those standalone nodes to be incorrectly considered by the listener landing page. This has been resolved by configuring the system to either return the local member when the cluster protocol is standalone or to return all Hazelcast members if the cluster protocol is Hazelcast.

Agent restart made more resilient
Resolved in Pega Version 8.7
During a timeout outage, agents intermittently encountered a NoClassDefFound error and were disabled. After the database connection was restored, the agents were not automatically restarting. This has been resolved by making the code more resilient to errors; agent will be restarted when a temporary issue is detected, and the restart will be immune to most exceptions.

Hazelcast packages expanded for Java9+ with kubernetes
Resolved in Pega Version 8.7
Hazelcast warnings were seen in cluster logs when Hazelcast was run in embedded mode or c/s mode on a java modular environment i.e. java 9+ which noted that performance and functional impact issues may result if certain internal modules of java are not given reflection access. This update provides the necessary access to some additional java internal modules/packages per the Hazelcast recommendation.

Schema packaging updated for better backwards compatibility
Resolved in Pega Version 8.7
After installing a hotfix, attempting to install another download which contained the same hotfix as a dependent resulted in the notification that schema changes were required and the message "ALTER TABLE pegadata.pr_archival_class_dependency ADD CONSTRAINT pr_archival_class_de_1812_PK PRIMARY KEY ("pzinskey")" was generated. Because the dependency already existed, attempting to install the hotfix failed until the constraint was manually removed from the database. Investigation showed this was caused by a difference in how schema was being generated for newer hotfixes vs older versions of Pega, and has been resolved by updating the schema packager and fixing the single col primary keys for Pega version 8.3 and lower.

Restore point handling updated for absent pzpvstream column
Resolved in Pega Version 8.7
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.

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.

Date normalization enforced for reference time
Resolved in Pega Version 8.7
A job which was scheduled to run weekly once on Monday at 8AM CET was running a second time at 9AM CET. Investigation showed the original recurrence pattern implementation was normalizing the reference time only at construction; this has been resolved by forcing the date normalization on each reference time update.
