Updated SimpleDateFormat to remove lenient parsing mode
Resolved in Pega Version 8.5.6
When using File Dataset to ingest CSV files with the required Date format set as yyyyMMdd, an error was thrown if the date value provided in a file was in the format '14/04/1971', but a date format such as 14-04-1971 did not produce an error but instead was mapped to a Date value of 00131204. . This has been resolved by disabling the lenient mode of parsing in SimpleDateFormat.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.5.6
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

PMML updated for nested 'if'
Resolved in Pega Version 8.5.6
Running a model on the openscoring API and the Pega PMML model gave different results. This has been resolved by updating the handling for nested 'if' in PMML.

Adaptive model retry mechanism enabled
Resolved in Pega Version 8.5.6
Adaptive models were missing from the Model Management page as well as in the Prediction studio while similar models for the same proposition, only differing by the Channel name, were visible. This was traced to data not being synchronized between the database and Cassandra. The pegadata.pr_data_adm_factory database table did not contain the record of the missing channel, but Cassandra did. Since the current Cassandra adm_scoringmodel contained model information, the system still believed the model was present. In order to ensure Cassandra and the database table are in sync, an update has been made to enable the retry mechanism "SyncFactoryKeysTask" to create the ADM model in factory table by periodically looking for scoring models without factories or an entry in adm_meta.

Cassandra driver metrics exposed for performance troubleshooting
Resolved in Pega Version 8.5.6
By default Cassandra driver metrics are now enabled. Metrics can be disabled by setting the dnode/disable_driver_metrics prconfig parameter.

Parameter logic updated for metrics activity counter
Resolved in Pega Version 8.5.6
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 8.5.6
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.

ADMinputsource field population updated to handle transactional decisions
Resolved in Pega Version 8.5.6
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.

Prediction outcome response timing updated
Resolved in Pega Version 8.5.6
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.

Added handling for calling truncate with external Cassandra
Resolved in Pega Version 8.5.6
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.
