INC-193632 · Issue 679173

Cassandra driver metrics exposed for performance troubleshooting

Resolved in Pega Version 8.6.3

By default Cassandra driver metrics are now enabled. Metrics can be disabled by setting the dnode/disable_driver_metrics prconfig parameter.

INC-193847 · Issue 695975

DSS added to allow masking of subjectID in alerts

Resolved in Pega Version 8.6.3

In order to allow customizing whether or not a subjectID is included in alerts, a DSS has been added to conditionally mask the subjectID from being logged. To use this, set the "alerts/maskIHsubjectID" DSS in the Pega-DecisionEngine ruleset to true to hide the pySubjectID.

Parameter logic updated for metrics activity counter

Resolved in Pega Version 8.6.3

An error was causing the PushCDHMetrics agent to fail. This was traced to an undefined parameter in the activity which was used as a counter, and has been resolved by replacing it with a local variable of type integer.

File Dataset wildcards updated for ADM storage

Resolved in Pega Version 8.6.3

Attempting to access the filepath was failing and an error was seen indicating "Could not obtain lock 'Create repository file pegacloudfilestorage:ADM/Rule-Decision-AdaptiveModel/Data-Decision-Request-Customer". While creating a file name, a lock is generated while checking the file names of existing files. If the file data set has a large number of files, a condition may occur where some threads are unable to save data and an exception is thrown. To resolve this, the wildcard previously used in the file name has been replaced with the Pega node id + thread id + current timestamp. This will ensure all wildcards are unique and there is no need to lock and list existing files.

INC-194405 · Issue 680278

Performance improvements for globally optimized strategies

Resolved in Pega Version 8.6.3

After update, the GOS_NBA_TopLevel strategy was consuming a large amount of processing time related to the hashmap. This was traced to the lookup of a value in a set of Class<?> that used Object.HashCode. To improve performance, the set lookup has been removed and replaced with checking validity by the type of an object.

INC-194433 · Issue 679631

Key Value Store handling revised for greater backwards compatibility

Resolved in Pega Version 8.6.3

Previous optimization work done to reduce the size of the "nm" field when the hierarchy string is empty resulted in some Key Value Store records not being read from older systems during update. This has been corrected.

INC-194657 · Issue 682006

ADMinputsource field population updated to handle transactional decisions

Resolved in Pega Version 8.6.3

The CaptureResponse flow was failing while writing to AdaptiveAnalytics with the error "IllegalArgumentException - argument does not represent JSON object". This occurred while running an outbound campaign where a few decisions were treated as transactional and did not have Model executions. Attempting to set a response for these decisions resulted in a JSON parse exception being thrown due to pxADMInputs not being populated (no models executed). This occurred only when using transactional actions in CDH, and was caused by the system only including predictive models during the make decision flow due to common inputs not being stored. While there was a workaround of overriding the property pzADMInputSource to use modelReferences instead of admInputContainer, this has been resolved by correcting how the pzADMinputsource field is populated. When there is no modelInput, the system will not populate that field so the page is ignored.

INC-194810 · Issue 691885

Removed services check and added warnings for simulations

Resolved in Pega Version 8.6.3

Attempting to run an audience simulation resulted in the error "Running simulations is not possible, because the required services are not available. Contact your system administrator to enable the data flow and real-time data grid services". Investigation showed the @DsmServices.pxHasFunctionalNodes("DataFlow","Batch") function call contained in the 'when' rule pyUnavailableDecisionServices was returning false even if all the nodes were in the cluster and all the DSM Services were in NORMAL status. To resolve this, the services check has been disabled and the simulation run will show a warning or fail if a data flow run is queued for more than 30 secs or if there is an issue with querying the underlying metrics storage.

INC-195197 · Issue 692148

Warnings added to prevent empty StrategyResult page

Resolved in Pega Version 8.6.3

When a Proposition Filter rule refers to a When rule that has "StrategyResult" declared in Pages & Classes but no "Param.StrategyResult", a design time warning will appear to indicate that this might cause discrepancy in globally optimized strategy (GOS) execution. * The warning message for a When rule with StrategyResult in Pages & Classes but not in Parameters: When rule [WhenClass: WhenName] does not have proper mapping for [StrategyResult] page. This would result in an empty [StrategyResult] page being passed into the When rule during execution. Please go to [WhenClass: WhenName] and add [StrategyResult] in the Parameters list and configure the mapping properly on Proposition Filter rule. * The warning message when StrategyResult is not in Pages & Classes but in Parameters list: When rule [WhenClass: WhenName] declares [StrategyResult] in Parameters tab, but isn't used in the conditions. This would affect performance during execution. Please remove the parameter from When rule [WhenClass: WhenName], and remove the Parameter mapping from the corresponding Proposition Filter criteria.

INC-195346 · Issue 682715

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.
