Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Index table correctly populates after migration
Resolved in Pega Version 8.7
After creating a product file with work instances, only some records were populating in the index-workpartyuri class through index rule. Investigation showed that if the IDs specified for the Work Range started with the same digits as were seen after the case prefix (e.g. W-1, W-1000, or W-22, W-2201) then only the indexes for cases that start with W-1 or W-22 were included in the export. This was traced to a step in AddPartyIndexWhenCondition where the EstimatedWorkPrefix local variable was calculated: the java step extracted anything that was the same from the start of the To and From range without taking into account the possibility that some digit characters after the "-" could be the same. To improve the accuracy of the prefix estimation, "-\d" will be used to make an educated guess.

Tracelist cleared to address parser exception in REST Service
Resolved in Pega Version 8.4.5
In a requestor pool of mixed types, HTTP and REST, the alert data was not initialized properly if there was a parse exception due to invalid data in the incoming payload. For example, last_input, first_activity, and last_step could all be left over from the prior HTTP service request. This was caused by the system pulling in seemingly unrelated activities for the "Last activity called" in the stack trace of a service when a single alert was created by two different service types which were sharing the same package, and has been resolved by explicitly clearing the tracelist for the service to prevent inaccurate information being reported in the logs.

Handling added for multi-file upload of duplicated files
Resolved in Pega Version 8.7
Attaching the same file multiple times during a single upload caused some of the duplicated files to not be included. The issue was not seen when attaching the same file multiple times but in different attempts. The exception "Can't continue with file attachment. FileData.xlsx is missing and might have been quarantined by anti-malware software" was logged. This was caused by the files being uploaded without updating filenames to have a unique ID, so multiple files with the same name were overwriting the previous file. This has been resolved by setting the appendUniqueIdToFileName parameter to true in the upload request so each copy of the filename is treated as an individual file.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.4.5
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

S3 attachment migration handles LInk-Attachment with multiple instances
Resolved in Pega Version 8.4.5
After S3 attachment migration, some attachments were intermittently not opening and displaying an error relating to being unable to load the file. Investigation showed that the attachments that failed to open did not have a pxStorageType tag in the XML of the work item. After the migration is done, the corresponding Data-WorkAttach-File and Link-Attachment instances are updated to point them to the repository. In this case, multiple LInk-Attachment instances were pointing to the same Data-WorkAttach-File instances, so only one Link-Attachment was updated and all of the other instances pointing to the same Data-WorkAttach-File instance were rendered unusable. While there was a workaround of manually updating the storage type in the database, this has been resolved by updating "pzgetattachmentcontent","pzupdatesourcereferences", and "pzuploadcontenttoexternalstorage" to check whether attachment is already migrated or not using the boolean parameter "isAttachmentAlreadyMigrated" to ensure all of the other Link-Attachment instances for a particular attachment are updated. If a migration was done and all Data-WorkAttach-File instances are pointing to a repository with some Link-Attachment instances not updated, those will be updated by running the migration again.
