Correct service instance name passed for data flow in DSMStatus
Resolved in Pega Version 8.1.8
When using the Connect-HTTP service "DSMStatus" to provide the node and status information as seen on the various tabs of the Designer Studio > Decisioning > Infrastructure > Services landing page, using DataFlow as the service parameter for the HTTP service method resulted in an empty response when the expectation was to get the information regarding the cluster details of Dataflow node type. This was traced to the service instance name not being parsed correctly when used for Data Flow services, and has been resolved by ensuring the correct service instance name is passed for this use.

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.1.8
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.

Statistic rounding error in ADMSnapshot Agent with Oracle corrected
Resolved in Pega Version 8.1.8
While running the ADMSnapshot Agent, the exception "internal.mgmt.Executable) ERROR com.pega.decision.adm.client.ADMException: Failed to complete ADM Data Mart snapshot" was seen. This was traced to an issue with the rounding of performance statistics when using Oracle, and has been resolved.

Performance and thread-handling improvements for SSA
Resolved in Pega Version 8.1.8
The SecureRandom class was used internally by SSAExecutionContext indirectly via UUID generation. Because this exhibited performance issues on some Linux environments, UUID has been replaced with static AtomicLong. In addition, a memory leak was observed when the strategy (SSA) execution resulted in an exception, and the strategy template has been modified to gracefully shutdown the VM under all circumstances. Thread-safety measures have also been tuned to be more fine-grained to reduce the potential thread contention that was seen while borrowing the SSAInterpreter object from SSAInterpreterPool.

Fixed flow line distortion in Process Modeler
Resolved in Pega Version 7.1.9
When clicking through to a subprocess from a parent flow (by clicking the + sign in the blue subprocess shape), flow lines in the subprocess were shown in a distorted fashion. When opening the same flow in a separate tab (by right clicking the blue subprocess shape and selecting Open Flow) the flow lines were correctly painted. This was an issue caused by the different renderings of the flow depending on whether there was a click through to it (with the + on the parent flow?s subprocess shape), or the subflow was opened in a separate tab (with open Flow). After the Process Modeler saved and checked-in the flow, the connector lines were re-drawn in ways that were non-intuitive and hard to interpret due to the edge routing in PM being calculated off incorrect input data that was taking into account shapes that were not represented on the screen. To fix this, the system now ensures the edges are routed without taking into account any shapes not represented on the canvas.

Timing updated for Cassandra session change thread lock
Resolved in Pega Version 8.1.8
An issue with unresponsive nodes was traced to the method used for notifications about Cassandra session changes. A thread trying to obtain a Cassandra session acquired a read lock, then if it then determined that a new session had to be created it would also acquire a write lock, preventing other nodes from trying to acquire the session. After creating a session, the thread notified all session change listeners while holding the write lock, causing deadlock with dependent services. To resolve this, the timing has been updated by moving the session change notification to the listeners outside of the section guarded by the lock.
