Fixed cataloging for framework hotfixes with non-java code
Resolved in Pega Version 7.4
The system was unable to catalog Strategic Application hotfixes that included non-java code instances (e.g. .xml or .properties files) due to Framework hotfixes using a different version format that caused validation failure. To correct this, the system will bypass redundant release version validation for Strategic Application hotfixes so that it can catalog non-java code instances.

Access Group Guardrail warning removed from password change
Resolved in Pega Version 7.4
Changing the password for the '[email protected]' operator generated the warning: 'The same Access Group should not be shared by Operators and Requestor Types. Access group PRPC:Agents was also referenced by Requestor Type DATA-ADMIN-REQUESTOR PRPC!BATCH'. The password change did take effect as expected. This guardrail warning was shown if the Access group used by the [email protected] operator, i.e. PRPC:Agents, was specified in any of Data-Admin-Requestor instance, and has been resolved by removing the unnecessary check.

Specification rule save-as loads requirements
Resolved in Pega Version 7.4
While doing 'Save As' of a Specification rule from a locked ruleset version to a higher unlocked version of the ruleset, the linked Requirements were not shown in the Requirements section under the Details tab. Sometimes a refresh would show the requirements, but intermittently an exception would be generated. This was traced to the system not auto-populating the requirements list on 'save as' of the specification, and code has been added to PostActionSaveAs of the 'Rule-Application-UseCase' class to populate the Requirements link on 'save as' of this rule.

Modifications to getFunctionalServiceNodes process
Resolved in Pega Version 8.2.7
The count of the Interaction History write related threads was increasing rapidly and a stack trace indicated "waiting on condition" and "java.lang.Thread.State: WAITING (parking)" errors. Investigation showed that this was due to getFunctionalServiceNodes using Hazelcast to determine node status by making a service request on an installation with a very large number of nodes, causing thread locking. To resolve this, the implementation has been updated to avoid calling getFunctionalServiceNodes on save of Interaction History, instead using Cassandra and only calling getFunctionalServiceNodes on the master node, not on all nodes.

Behavior made consistent between SSA and legacy engines
Resolved in Pega Version 8.2.7
There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

Updated precondition checks for Tumbling Time data in event strategies
Resolved in Pega Version 8.2.7
Tumbling Time data keys in event strategies were not being properly executed when certain window configurations were used. This was has been resolved by turning off the optimalization of Cassandra reads for small windows when window size is not known upfront and set dynamically (set size by property). In addition, an issue with Cassandra timeouts after the dataflow run had been running for several months has been resolved by adding a 'time to live' value for tumbling time windows, and event strategies has been switched to use leveled compaction by default.

Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.2.7
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.2.7
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.
