Added parser retraining for intermittent email issue
Resolved in Pega Version 8.6.3
An email listener was intermittently failing to pull the data from the email subject into the required property in the email triage case. Investigation showed that the pxEmailParser was excluding the first line in the incoming text for some cases, and has been resolved by adding code to retrain the email parser.

HandleResponses updated for use with optimized campaign
Resolved in Pega Version 8.6.3
After updating from Pega 8.4, responses were not processed in the pxHandleResponses Data flow if the "pyCampaignOptimization" flag was set to true. This was traced to a missed use case for an optimized campaign, and has been resolved by modifying the condition in HandleResponses.

Handling added for special characters in dataflow and mbean name
Resolved in Pega Version 8.6.3
Exception errors from deleted email listeners were seen after server start-up. Investigation showed that when a dataflow stage name had a special character and that name was then used in the mbean name, it was failing to register. This has been resolved by escaping JMX key values if they contain special characters.

Debugging enhancements for globally optimized strategies
Resolved in Pega Version 8.6.3
When a null pointer exception was encountered during globally optimized strategies (GOS), the logging included a long chain of exceptions and the most useful information was not easily visible. To improve troubleshooting, the error message has been modified to show the actual cause of the error first. A catch has also been added to better handle any null pointer error after db.open and db.opendefault.

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.6.3
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Prediction outcome response timing updated
Resolved in Pega Version 8.6.3
Predictions using a response timeout were not emitting a negative response ('NoResponse') when the specified waiting time expired. This was traced to the the outcome and response timeout values being overridden while triggering responses for multi stage predictions along with chained predictions. This has been resolved by modifying the flow to emit each outcome as it is received and by adding the dataflow trigger in the function so that it does not override the values in case of chained predictions.

Tombstone cleanup modified to handle very large volume environments
Resolved in Pega Version 8.6.3
Cassandra nodes were periodically suffering from an out of memory condition. This was traced to tumbling windows creating too many tombstones for Cassandra to clean up effectively when running in a very high volume environment with a short tumbling time. This has been resolved by modifying the procedure away from using individual tombstones to instead use range tombstones which will continuously supersede the previous tombstone so there is never an opportunity for them to build up.

Added handling for calling truncate with external Cassandra
Resolved in Pega Version 8.6.3
A JMX exception was generated when using external Cassandra. This was traced to the combination of calling truncate and using external Cassandra for DDS, and has been resolved by adding a 'do not execute' consistency check during a truncate operation when using external Cassandra.

Scenario Planner performance improvements
Resolved in Pega Version 8.6.3
Scenario planner runs were causing out of memory errors on the dataflow nodes. To resolve this, updates have been made to improve performance. Only relevant information will be kept for decision funnel simulations out of SR pages, the memory footprint of data structures used to aggregate and rollup counts has been reduced, and temporary objects will be released as soon as they are not needed anymore.

ADM group chart level working in Prediction Studio
Resolved in Pega Version 8.6.3
Charts were not visible for Group level ADM in the Prediction Studio Models tab. This was traced to an unneeded filter for this version of Pega and has been resolved by withdrawing the filter.
