Resolved timeout errors related to getIndexInfo
Resolved in Pega Version 8.1.8
When attempting to import large files (around 300MB) via Designer Studio a time out error was seen, but the same upload worked as expected from the command line. Investigation showed that the "approximate" argument in getIndexInfo caused wasteful analytic operations to be run on the database, hampering performance. To resolve this, areas where the results of the analysis are not needed have been modified to have aApproximate set to be true so it will not be run.

Handling added for clearing node killed between assignment and processing
Resolved in Pega Version 8.7
An Offer flow was not resuming after it expired according to the wait shape. Investigation traced this to partitions which were assigned to a dead node in NEW state where they were not picked up by the dataflow. The problem was only encountered in the unusual situation when a dataflow node was killed in the brief period of time between the assignment and the processing, and has been resolved by adding an update which will clear unknown new assigned partitions for the batch run health task.

Support added for nested grids with child categorization
Resolved in Pega Version 8.3
Show Details and Expand All were not working as expected in a repeat grid with a nested grid scenario where the parent grid had Show Details enabled and the child grid had categorization enabled with one column selected for categorizing. Investigation showed that a null page was being passed (final @baseclass pzGridSortPaginate activity) due to a lack of support for considering page lists that are embedded in a page different than the step page. To add this support, the activity has been modified to use tools.getProperty(...) instead of myStepPage.getProperty(...) if the data source page list is not an embedded property in the parent row page.

database table mapping will check for existing properties before creating them
Resolved in Pega Version 8.3
Using the Database table class mapping tool to map an external database table to a class and create properties according to columns in the table was resulting in the property being created as 'not available' and not case sensitive if the property to be created while mapping was already present in the inheritance hierarchy. This led to an error caused by the property validation failing in the validateReportDesignTab activity. Previously the database table mapping tool did not check to see whether the properties to be created existed already in the parent class hierarchy. With this update, the system will check before allowing the mapping, and if the properties exist in the hierarchy already they will not be populated.

Timing updated for Cassandra session change thread lock
Resolved in Pega Version 8.1.8
An issue with unresponsive nodes was traced to the method used for notifications about Cassandra session changes. A thread trying to obtain a Cassandra session acquired a read lock, then if it then determined that a new session had to be created it would also acquire a write lock, preventing other nodes from trying to acquire the session. After creating a session, the thread notified all session change listeners while holding the write lock, causing deadlock with dependent services. To resolve this, the timing has been updated by moving the session change notification to the listeners outside of the section guarded by the lock.

Additional diagnostic logging added for ElasticSearch startup issues
Resolved in Pega Version 8.7
The PyIndexerState was stuck in Starting status during node initialization. This issue could occur if the filesystem became hung due to network level issue while scanning entries from /etc/mtab, resulting in a lock which was not released correctly. In order to better determine which node entry in a cluster may be responsible for the hang, an update has been made which will use a temporary virtual environment to repeat the part of the initialization phase responsible and generate additional logs for debugging. To activate this, the PegaSearch.Diagnostics logger must be set in DEBUG mode. This duplicated virtual initialization will not interrupt the normal initialization.

Review/Perform harness modifications for scheduled report errors
Resolved in Pega Version 7.3
Scheduled reports would periodically go to Completed state and stop running prematurely. Deleting and then reopening a scheduled report (from recents) caused corruption of scheduled reports that are re-scheduled. This was traced to the Review/Perform harness going in to a corrupt state, and has been corrected by re-building the Review harness as well as some minor changes to the Perform harness to ensure the correct buttons are displayed when deleting a scheduled report and reopening it from the recents list.

Map from field updated to ensure Correspondence Name and Type are included
Resolved in Pega Version 7.3
An error was generated while configuring a Map From field as Correspondence. This was an issue with the Correspondence Name not being passed: when the Map From is selected as Correspondence, the backend expecting the Map from Key as a space separated combination of Correspondence Name and Correspondence Type. If only the Correspondence Name was selected, then the back end failed to find the Correspondence Type. This has been fixed by modifying the code to combine left and right from key part to ensure both parts are sent.

Repaired instance insertion for REST connection invoked via Queue
Resolved in Pega Version 8.3
After upgrade, the REST connection invoked in an activity which in turn called out-of-the-box ProcessQueue was not getting the response into the SYSTEM-QUEUE-EXECUTIONREQUEST-CONNECT-CREATEBOOKING instance. The right response was observed coming from other source systems in the logs, and the work object status also changing as expected. This has been resolved by exposing a DSS to revert to the old behavior of Response being present in the queueItem when a connector is queued for execution.

Inference engine enabled to resolve JourneyManager data flow exception
Resolved in Pega Version 8.3
Customer environments were intermittently seeing an exception with the error "Could not get ultimate primary destination for data flow .DF_JourneyManager" when trying to compile an activity that ran a dataflow that ultimately called the DF_JourneyManager data flow. This error was traced to the Inference engine being in a disabled state so the system was not able to get the dataflow output class via declare expressions. The Inference engine has now been enabled to resolve this issue.
