Check added to minimize Obj-Open-By-Handle error logging
Resolved in Pega Version 8.4.2
When using a Data Type with the "Automatically generate a unique id " option, calling the Save-DataPage method by using the savable data page of the data type finished correctly but showed Obj-Open-By-Handle errors on PegaRules.log. Investigation showed the exception was thrown when running the save plan from DataPageSaverImpl: while attempting to run the save plan, the system does not know whether a parameter (pyGUID in this case) will be required to run the save plan or not, meaning that it can't detect any possible error in DataPageSaverImpl. The implementation instead makes a call to db.open to check if an instance exists and hence logs are thrown. To resolve the error logging, a check has been added: if the save-to class has an autogen key and the savable data page instance doesn't have the autogen key in it, the system will directly call pxCreateRecord. This will avoid a call to db.open to check if instance exists and hence no failed logs will be thrown. This partial change will work only for classes having an autogen key and in cases where the page is trying to create a record by intentionally not passing the key.

Email attachment linefeed formats preserved between Oss
Resolved in Pega Version 8.4.2
When MIME attachments were stored in Data-WorkAttach-File instances and then later attached to outgoing email sent by Outlook, text files that originally had the Unix linefeeds (LF) had those changed to the Windows CRLF line endings when the Content-Transfer-Encoding is set to 7bit. To resolve this, the java mail DSS email/encodeEolStrict now defaults to true to preserve line endings in outbound email.

Parse Delimiter rule updated for special character handling
Resolved in Pega Version 8.4.2
Attempting to run a Parse Delimiter rule with a CSV file was failing with a 400 bad request and the message "Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986." Inspecting the HTTP request showed this was an issue with the \ character value being present in the FilePath property. To resolve this, encodeURIComponent() has been implemented to ensure the FilePath parameter of the HTTP Request meets Tomcat restrictions.

Alerting features added for Listeners
Resolved in Pega Version 8.4.2
An enhancement has been added for Email Listener alerts. At the end of each listener's processing cycle, the system will determine the average processing time per message, the total processing time of the listener, the total unread messages count, and total number of messages processed. In each AESRemote agent run, this data will be published to the PDC, where it will be analyzed and any necessary alerts raised.

Toggles added to allow file listener performance improvement
Resolved in Pega Version 8.4.2
In order to offer flexibility in improving the performance of file listener CPU usage while processing intake files, rsf.setSaveIntermediateState( true ) has been replaced with rsf.setSaveIntermediateState( listener.getListenerProperties().getAttemptRecovery() ) in FileActionImpl. This change allows the option of not selecting the setting for attempting recovery on the file listener rule-form, which then would skip the intermediate save state normally performed per record/per file in case recovery is needed, thereby speeding up the processing. A toggle has also been added to see whether the system should bypass the ListenerState check at the end of each record. To use this, set the Dynamic System Setting "listener/skipListenerStateCheck" in the "Pega-IntegrationEngine" ruleset to true.Additional Installation Instructions Please create/set the Dynamic System Setting "listener/skipListenerStateCheck" in the "Pega-IntegrationEngine" ruleset as true.

Topic name prefix support added for Kafka
Resolved in Pega Version 8.4.2
An enhancement has been added to support the use of site-specific standards for the naming of queues. This can be used to add clarification between Kafka Topics created by Pega and those created for internal topics when using a shared Kafka Cluster. This is done using the new setting: <env name=”services/stream/name/pattern” value=”prefix{stream.name}postfix”/> .As an example, if tenant.name is resolved into "myco" and the environment into "prod1", value="{tenant.name}-{environment}-{stream.name}" will result in stream myco-prod1-{stream.name} By default, when stream.provider = EXTERNAL, the default will be “pega-{stream.name}” .

Landing page refresh modified to avoid frequent reloads
Resolved in Pega Version 8.4.2
Approximately every two weeks, clients were able to login but it was not possible to work as the landing page refreshed constantly until all of the nodes were rebooted and the issue was cleared. Investigation indicated the frequent reloads were related to the cacheing of the operator details, and this has been resolved by updating the datapage reload strategy based on 'when' so frequent reloads will be avoided.

Handling added to avoid primary key exception in pxExtractDataWithArgs
Resolved in Pega Version 8.4.2
While running the activity pxExtractDataWithArgs with -c, the "Error while getting the sequenceNumberERROR: duplicate key value violates unique constraint pr_log_pk" occurred if both Parent and Child classes were pointing to different table and extraction started from the child class. In this case, because the Parent and Child classes were pointing to different tables while extracting with the -c option, the class list order caused a primary key constraint violation exception while generating the process sequence number. To resolve this, while adding the classes to the instance map, the order will be changed to parent followed by child classes.

Handling added for BIX count mismatch in manifest and extracted CSV data
Resolved in Pega Version 8.4.2
A mismatch in the counts in the manifest file when compared to the data extracted in the CSV files was traced to a corrupted or wrong pzinskey in the source database. If the BLOB is corrupted while extracting to output type and manifest type to CSV, an invalidstream exception was generated and resulted in the manifest file and extracted CSV file total instance count mismatch. This has been resolved by adding handling to balance the counts.
