Data flow stability improvements
Resolved in Pega Version 8.6.4
All nodes were showing as active and running in the cluster, including background, stream, web nodes, but the queue processor would not start. Log entries indicated "IllegalStateException: Invalid run transition found [PENDING_NODES->COMPLETED] on run [DF_OutboundPreProcessing_SMS] by [EventDescription{originator=CheckNodeAvailabilityTask, reason=Restoring previous state." Due to this, all dataflows were moved to queued state. As soon as the corrupted dataflow was deleted the other dataflows were resumed. To resolve this, data flow stability improvements have been added along with better handling of runs in Queued state.

Addressed performance issues for classless DSMClipboardPage
Resolved in Pega Version 8.6.4
The DSMClipboardPage implementation handles Page Group access as a classless page (i.e. pxObjClass = ""), creating potential performance issues in implementations where the page group is used with a very large number of distinct AccountIDs in a short period. This has been resolved by updating the system to not cache keys for page group classless page.

Refresh added to limit commit log partition size
Resolved in Pega Version 8.6.4
Issues were seen on DDS nodes, including slowness and randomly dropping out and being replaced by new nodes. WARN messages in Cassandra logs reported issues relating to a large partition size of adm_response_commit_log_date_tiered table. Investigation showed the large partition size (over 10GB) was causing frequent C* query timeouts due to scanning a large number of tombstones, resulting in node terminations. This has been resolved with an update which will limit the commit log partition size by refreshing the NID every set interval.

Additional logging and executor work for Adaptive Decision Manager
Resolved in Pega Version 8.6.4
The Adaptive Decision Manager Pulse operation stopped running on some of the ADM nodes, causing an impact on the model update. To address this, some additional protections have been added for pulse operations running in a scheduled executor, and ERROR logging has been enabled.

Simplified default reference time calculations
Resolved in Pega Version 8.6.4
After a job scheduler was configured to run at Start time = 21:00:00 for Time zone = Europe/London, the scheduler determined 20:00:00 as the next start time. This was due to the calculation for the next start time using the time zone offset calculation pattern for the date and time stored in System-Runtime-Context.pxCreateDateTime, which had difficulty with changes to the time zone definition implemented in the time between the given date and today (meaning the current time) such as daylight savings time. To resolve this, the default reference time from System Runtime Context will be 'now' instead of Date(0).

PRconfig added for JVM user/password
Resolved in Pega Version 8.6.4
The setting Dcom.sun.management.jmxremote.local.only=true has been added for use when JMX authentication is enabled by providing jmxuser/password through prconfig.

TextMask_Encrypted rule added for use with Oracle
Resolved in Pega Version 8.6.4
When a property was being encrypted by propertyEncrypt access control policy and masked by propertyRead access control policy, it showed a "@@getMaskedValueOfText" error. This has been resolved with the addition of a new rule pxTextMask_Encrypted for Oracle product type which will remove extra spaces from the SOURCE string to handle ORACLE specific usecases.

Delay Factor updated to allow values < 1.0
Resolved in Pega Version 8.6.4
After modifying the "Delay factor" parameter on a queue processor rule and and clicking the "Save" button, refreshing the page caused the value of the "Delay factor" parameter to change. This has been resolved by updating the delay calculation strategy to support factors < 1.0.

Enhancements added for external Kafka Stream Service
Resolved in Pega Version 8.6.4
To ensure data privacy when using multi-tenant Stream Service hosted on a single Kafka cluster, access will be authorized based on ACLs when a tenant sends direct requests to Kafka. In addition, all Kafka resources (topics and consumer groups) are now able to contain a prefix naming convention which can be used for tenants. This is handled through using a <env name="services/stream/name/pattern" value="{tenant.name}-{environment}-{stream.name}"/> prconfig setting to set the stream name pattern. For example, if the tenant.name is resolved into "companyname", environment into "prod1", and the stream dataset name is pyFTSIncrementalIndexer, then the Topic name created on the external Kafka will be companyname-prod1-pyFTSIncrementalIndexer.
