ReportStats delete query performance improvements
Resolved in Pega Version 8.6.5
A database connection spike was maxing out the allowed database connections, causing login delays and termination of stream nodes. Investigation traced this to the delete query on pr_log_reportstats, which was a full table scan generated from SQLGeneratorPostgres.purgeTableContainingClass. To improve performance, the full table scan sub-query has been removed and 'limit' syntax has been added to run the necessary deletion in batches.

Security update enhanced to support custom implementations of InvokeAxis2
Resolved in Pega Version 8.6.5
The QueueProcessor activity indirectly invokes a Connect-SOAP. After installing the Security A22 patch, custom implementations on InvokeAxis2 reported runtime failure. This has been resolved by replacing reflection library use with explicit type checking and casting to get the array length in step 14 of InvokeAxis2.

InvokeHTTPConnector security updated
Resolved in Pega Version 8.6.5
"Allow invocation from browser" has been disabled for InvokeHTTPConnector, and "Require authentication to run" has been enabled. In addition, an unsafe reflection used to load JCIFS libraries for NTLM operations has been removed, which removes support for custom JCIFS libraries in Connect HTTP.

Added explicit clearing for AsyncServiceManager cache
Resolved in Pega Version 8.6.5
Heap size for multiple JVMs increased after update. Investigation showed data pages loaded via Load-DataPage during service processing using requestor pools were cleared after each service interaction but the AsyncServiceManager cache was not cleared. To resolve this, an update has been made that will clear the async cache when the requestor is returned and when flush all is called.

GET API will skip case locking
Resolved in Pega Version 8.6.5
After update, performing a GET call on an assignment was unexpectedly locking the case. This was traced to a difference in handling: Pega 8.3 performed an Obj-Open-By-Handle of the workobject without acquiring a lock, while Pega 8.6 calls Assign-.acquireWorkObject which acquires a lock on the work object thereby affecting the other requestors from accessing the case. An initial fix for this issue enabled optimistic locking, however this did not resolve the issue in scenarios where there were concurrent calls and optimistic locking was not used. This additional update will skip locks on the work object for V1 GET assignments/{id}, GET assignments/{assignmentId}/actions/{actionId} and GET cases/{caseId}/actions/{actionId} and corresponding action refresh APIs.

Enhanced SSA metrics made available
Resolved in Pega Version 8.6.5
In order to better diagnose delays related to the time when a Campaign is scheduled to start and the time when the Dataflow actually starts to run, an update has been made which will generate detailed metrics to cover some of the strategy execution key performance intensive areas. Additional lower level internal metrics related to SSA engine execution have also been made available by way of a DSS to collect more runtime insight for diagnosis. To enable the collection of these Level 2 SSA internal metrics, set the dataflow/shape/strategy/detailed_metrics/level2 DSS in the Pega-DecisionEngine rule set to 'true'. A comprehensive set of enhanced metrics will be available in Pega 8.8.

Updated context handling for executing data transforms in dataflows
Resolved in Pega Version 8.6.5
When performing a sort operation in a data transform on a page list and invoking the Data transform through a Data flow, a java.lang.UnsupportedOperationException was generated on the sort step even though the data was correct. Investigation showed that the dataflows were using a different execution context than the context used for regular activity execution. An update has been made to ensure the correct context is being used while executing data transforms in dataflows.

Explicit Kerberos renewal added for HDFS
Resolved in Pega Version 8.6.5
When using WebSphere/IBM with Hadoop connectivity, the Kerberos credentials were expiring after 7 days and causing connectivity failures. Investigation showed the Apache Hadoop HDFS Client was not renewing the ticket even when there were operation calls every few hours. To resolve this, an enhancement has been added to the Pega HDFS client which will explicitly tell Hadoop authentication layer to check for Kerberos ticket renewal instead of relying on Hadoop built-in logic.
