INC-143121 · Issue 610732

Timeout for loading predictors made configurable

Resolved in Pega Version 8.3.6

When using an extremely large number of predictors, the Report definition pzADMPredictorsFilter was suffering timeouts due to the time for loading predictors from the database exceeding the time threshold allowed. This has been resolved by marking the rule as editable to allow custom setting of the threshold according to need.

INC-148899 · Issue 615702

Adaptive models update correctly

Resolved in Pega Version 8.3.6

Some models had the recorded responses column updated, but the models (number of Positive, Negative and Processed Responses) were not updated. Investigation showed that deleting the modelRuleConfiguration through the stateManager/client did not delete modelFactories related to the configuration. If a new configuration came in with a different algorithm, the update issue occurred. This has been resolved by reseting the configuration according to its factory in that specific case.

Locking added to avoid null pointer error for auto-populate property

Resolved in Pega Version 8.3.6

After configuring the auto populate property "OrgProduct" which referred to a data page, the system experiencing heavy load led to the property not getting properly initialized. This resulted in a WrongModeException and NullPointerException. To resolve this, the system has been updated to lock the requestor when Queue Processors execute their activity. This will prevent race conditions and concurrent modifications if other threads are accessing the same requestor.

Duplicate key exception resolved for adaptive model

Resolved in Pega Version 8.3.6

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.

INC-160331 · Issue 628710

ML model continue tag error changed to debug logging

Resolved in Pega Version 8.3.6

Log entries were seen indicating "The continue tag is found without a start tag for window Line1 1234567890 in text". This appeared to be coming from the MLCommand java class. Investigation showed this occurred when the ML model believed a portion of the text (token) was a continuation of the entity because it has not found the starting part of the entity. This situation is not currently treated as a valid output, so an update has been made to change the logging level from error to debug for this case.

SR-69015 · Issue 619995

Unescaping characters implemented for expressions

Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6

An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals (that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.

SR-D26976 · Issue 507215

Filter added to ensure correct context for proposition strategy rules

Resolved in Pega Version 8.1.7

Given two applications (ex App1 and App2) hosted on the same domain where App2 was built on App1, trying to create a strategy rule in App1 and do a test run strategy using the propositional data component which internally uses App2 propositions generated the error: Failed to find a 'RULE-DECISION-DECISIONPARAMETERS' with the name 'GROUP_2'. There were 1 rules with this name in the rulebase, but none matched this request." Investigation showed the strategy was using the PropositionNoCacheUtils and PropositionTools java classes to load the propositions during run time. In these classes, the group classes were browsed from the db irrespective of the application context, causing the strategy run to fail as it was not able to access the decision data rules in other applications which shared the same SR class as the current application. To resolve this, a filter has been added to the PropositionNoCacheUtils and PropositionTools java classes to filter out the groups that are not in the current application context.

SR-D31103 · Issue 502980

VBD insert process updated for better retry handling

Resolved in Pega Version 8.1.7

When restarting Data Flow and VBD nodes, the VBD client can encounter some exceptions indicating components in the stack are temporarily unavailable. In most cases the VBD client retries, but there are some cases where it did not and data flow failures occurred. To resolve this, the code has been updated to remove logging of the VBD cluster status during a retry, and the retry duration has been made configurable.

SR-D37163 · Issue 505479

Corrected Decision Data import filter behavior

Resolved in Pega Version 8.1.7

After upgrade, if a Decision data import referred another component to filter out the import, it did not work. This has been corrected.

SR-D38492 · Issue 505491

Batching now enabled when using IH Summary shape in substrategies

Resolved in Pega Version 8.1.7

Batching was not being enabled when using IH Summary shape in substrategies. This was traced to the IH_SUMMARY_CACHE field not automatically being passed to sub-strategies, and has been corrected.
