Tokenizer updated to handle commas

Resolved in Pega Version 8.4.5

The Text Analyzer was not working as expected in cases where the number was combined with a comma (,) with it but was working when a space was used between the number and the comma. This was traced to the tokenizer not correctly processing and splitting the input text when there was a special character before or after the token. This has been resolved by updating the tokenizer logic.

Performance improvement for saving ADM model rule

Resolved in Pega Version 8.4.5

Saving an ADM model rule generated a heap dump. The stack trace from the heap dump showed a thread consuming the maximum memory (4.7 GB of memory). Configurations on all factories are updated when a model rule is saved, but at the time of development it was not expected that there would be a lot of factories in a Dev environment so the system was loading all existing factories simultaneously into memory and updating configurations on them. To improve performance, an update has been made which will now sequentially load factories and update the configuration.

Materialization uses time limit boundary for query

Resolved in Pega Version 8.4.5

After turning on Materialization for pyIHSummary and OfferOutcomesForPast45Days datasets, an SQL query was taking an excessive amount of time and causing multiple alerts in the logs. Investigation traced the issue to database partitioning, specifically that running a query where the pyOutcomeTime range spanned multiple partitions was causing the indexes for all partitions in the range to be opened. To resolve this, the query has been updated with a DSS to support a partition size of min(pxOutcomeTime) to limit the time range to querying day by day, or hour by hour, or any other chronology unit specified. If there are no records for the current limit, then it will look at the next partition. This should prevent the query from needing to open more than 1 or 2 partitions.

Hazelcast remote execution not called from synchronized context

Resolved in Pega Version 8.4.5

After navigating to the Admin Studio portal to view the nodes, the portal was temporarily freezing. Investigation of the thread dump revealed this was caused by a DDS pulse sending a remote execution call to all nodes to update logger settings even though the site was not using DDS. This has been resolved by updating the system to avoid calling Hazelcast remote execution from a synchronized context.

Duplicate key exception resolved for adaptive model

Resolved in Pega Version 8.4.5

During the model snapshot update, a DuplicateKeyException was generated while trying to insert a record in to the predictor table. This did not affect the model's learning, but did appear ion the model monitoring report. This was traced to a local scenario of having the same outcome values defined on the model with different cases (Accept and accept). All predictors used in an Adaptive model are inserted into the model monitoring tables as a part of the monitoring job: because the monitoring tables are not case sensitive, this lead to a unique constraint exception since there were multiple IH predictors with the same name. To resolve this, validation has been added which will skip adding duplicates from new responses.

DSS added to create consistent handling of longform datetime

Resolved in Pega Version 8.4.5

After upgrade, a difference in handling related to datetime value was seen. For example, EmailSchedRunEndDate is a date type property holding the value "20201016T000000.000 GMT"; in Pega v7.4, a substring function was used to move the extra characters from the date field ex. EmailSchedRunStartDate = @substring(.EmailSchedRunStartDate,0,8), but in Pega v8.4 and higher the long datetime value ( "20201016T000000.000 GMT") was still being used for the date field. This long value was then truncated to 2020101+ when saving to the database, causing errors in later steps. However, research found that if there is a call @toDate function before this step for any other field, the correct date value was set for EmailSchedRunStartDate. While ClipboardPages separate Dates and DateTimes, internally, in Java, both have a time component. The implementation of DSMClipboardPage made no difference for serialization and appended the time component for pure Date properties. To create consistent handling, an update has been made to optionally set the correct behavior after setting the Dynamic System Setting by way of "Pega-DecisionEngine dsm/clipboard/correctDateFormat -> true". This setting would only take effect after a restart of Pega, and the default is false in order to not disrupt any application inadvertently relying on this behavior.

Updated report handling for simulations using database output

Resolved in Pega Version 8.4.5

When running a simulation with a database table as the output destination, the pxObjClass property was not populating with a value in the results. This caused sub-reports to not be populated with data. Investigation showed that issue happened when the simulation output destination database table was inferred as an external table due to not having an exposed column for pzinskey. To resolve this, the pxObjClass and pxCreateDateTime properties, which were added to simulation output destination tables for compatibility with Report browser, will not be added to those tables when they are created. Instead, to address compatibility issues of simulation output destination classes with Report browse in the Customer Decision Hub, the pyDefaultSummaryReport has been brought up into the Data-Decision-StrategyExecution-ResultOutput class from the @baseclass.

Refactored resultset iteration to resolve idle alert

Resolved in Pega Version 8.4.5

Some data flow pulse tasks were executing other database queries while iterating a resultset, leading to an alert being logged indicating "Database pid [29226] in state [idle in transaction] for 15195 ms, the threshold is 5000 ms" because of the amount of time the database was being held open. This has been resolved by refactoring the tasks to make sure they don't do heavy input/output work while iterating over the resultset.

Logic updated for finding 'Last' in Interaction History

Resolved in Pega Version 8.4.5

The 'LastReponseDate' and 'LastInteractionId' in the Interaction History summary data set were null. Investigation showed that reusing the ESM component in the aggregation dataset caused any assumptions made during the optimization of ESM to not be true anymore. To resolve this, the logic of the Last aggregation has been modified to not rely on a Last event which might not be stored in-state (such as optimization), but rather to use the list of events which is always stored.
