INC-177031 · Issue 664856

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.

Modified batch requestor handling to ensure cleanup

Resolved in Pega Version 8.5.6

A large buildup of batch requestors was seen, and restarting the node did not clear it. Investigation showed that in the case of one class reading a DSS value, a Pega requestor was being created when it was unable to retrieve any Pega context, and this requestor was not cleaned up afterwards. To resolve this, an update has been made to the way the requestor and Pega context is being created along with ensuring it will be cleaned up properly after use.

Resolved error during save of a Predictive Model

Resolved in Pega Version 8.5.6

Attempting to save a predictive model in Prediction Studio resulted in the error ".pyModelProcess.pyShapes(Setmodelcontrolgroup).pyMOName: Cannot generate the component ID from the provided input. Enter at least one alphabetic character." This was traced to previous work done around defining a control group using a property reference, and has been resolved.

INC-183211 · Issue 667010

Compare-To-Empty-String support added to Analyzer

Resolved in Pega Version 8.5.6

An enhancement has been added to support a NotEquals decision function in the Analyzer.

INC-184352 · Issue 671895

Predictive model snapshot generation updated for Java 11

Resolved in Pega Version 8.5.6

While the Simulation data export case type was executed as expected, the predictive stages showed zero records processed. This was traced to instances running on Java 11 which caused an issue with the snapshot process. This did not affect learning, but visualization and reporting were not working in Prediction studio. To resolve this, an update has been made to the snapshotID for Java 11 compatibility which will generate a random UUID instead of using a seed.

INC-185045 · Issue 672417

Performance improvements for action check-in

Resolved in Pega Version 8.5.6

The process of 'Saving As' an action to a higher ruleset, Saving, and then running Check-in was taking an excessive amount of time. This was traced to redundant page copy activities and performance has been improved by updating the implementation.

INC-186437 · Issue 685014

Updated entity attachment extraction tokenizers

Resolved in Pega Version 8.5.6

After creating an entity extraction model, it was seen that one of the entities worked when there was a space after the semicolon but the detection was not working if there was no space. This has been resolved by updating the Tokenizers with extra examples to address tokenization when ":" is present between two words without any spaces.

INC-186889 · Issue 674013

Unused DSS compiledExpressions now defaults to false

Resolved in Pega Version 8.5.6

After updating from Pega 8.2 to Pega 8.5, executing a test campaign failed with an error in logs. This occurred when running Distribution tests with "Include funnel analysis reports" checked, and was traced to the DSS setting "decision/strategy/ssaVM/compiledExpressions". As this was previously used to toggle a feature which is no longer in use, the default setting for this DSS has now been changed to false to resolve this issue.

INC-187520 · Issue 677872

Actuals sync clears data from cache and persistence

Resolved in Pega Version 8.5.6

When sync attempted to clear the existing data from Actuals before copying data from the interaction history, the partition was cleared from the cache but not from persistence. IH data that was then copied to the same partition time ranges had new field descriptors created that did not match the format of the old data in persistence. As a result, when a query triggered the loading of such a partition, the mix of data with the old and new formats caused the load to fail. This has been resolved by updating the system to ensure the data is deleted properly from both the cache and persistence.

INC-188309 · Issue 684701

Proposition filter populated for test business Issue

Resolved in Pega Version 8.5.6

When running the proposition filter rule, no drop down list appeared for a business issue. This was caused by the Issue list not being populated for the Action-Run test page, and has been resolved.
