Performance improvements for sites with a large number of tables
Resolved in Pega Version 8.3.6
Performance impacts were seen when there were a very large number of tables in the database and the cluster/node persistence jobs were running. This was traced to the volume of metadata / schema introspection queries fired from the pyPersistNodeState and pyPersistClusterState jobs along with the Classmap cache invalidation / lookup queries, and has been resolved by improving the code to avoid database introspection when the current number of tables is greater than a maximum value.

Optimizing helper class enhanced to handle external databases
Resolved in Pega Version 8.3.6
Running a BIX extract that included a manifest for a target database was resulting in a null pointer exception for the manifest extraction. Attempting to generate the DDL for the manifest table also failed. This was traced to an issue with the helper class using a hardcoded default database for forming the queries, causing it to ignore the DB config/DADN/prconfig for the Oracle database and form a query using the PegaRules' database credentials. This only occurred when trying to do external database operations on a different DB platform; Oracle PegaRules worked as expected with an Oracle external DB and Postgres Pegarules worked with a Postgres external DB, but mixing Postgres PegaRules and an Oracle external DB would result in the null pointer error. To resolve this, the helper class has been enhanced to work with external databases by passing the database name as a parameter so it will properly calculate the query based on the type of target. The default for 'database/oracle/allowOptimization' is set to false: additional database privileges must be added or some configurations must be updated to provide the information needed in lieu of the privileges before making use of these optimizations. In addition, an error in the name of the class has also been corrected and is now available as PerformanceHelper rather than the previous "PerformaneHelper".

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.

Decision table query performance improvements
Resolved in Pega Version 8.3.6
Severe latency was seen after upgrade, and it was not possible to save business rule changes. This was traced to an issue with the decision rule being treated as a custom rule, and has been resolved by inserting a check. In addition, optimization has been added for queries on the pr_sys_decchg table.

Resolved PRQueueLockException
Resolved in Pega Version 8.3.6
A Class Queue not found exception resulted when an SLA was deleted on the same transaction where it was created when deferred save was used. This was an inadvertent side effect of work done on the QueueManager implementation to invalidate previously deferred operations for item and schedule removal, and has been resolved by clearing the processing state for PRQueueLockException when an item reservation fails.

Localization added for currency values using commas vs decimal points
Resolved in Pega Version 7.1.8
Excel within PRPC was not properly localizing for the use of decimal and comma as thousand and decimal separators for decimal/double currency property values, a use that is common in non-English installations. The records editor has been changed to support localization for properties of type double and decimal.

Epilog activity correctly executing for asynchronous queues
Resolved in Pega Version 7.1.8
When configuring a File Listener and Service-File for Asynchronous execution queue, the Epilog activity was not being executed. There was a workaround of switching to synchronous execution, but this issue was traced to a logic flaw that created a race condition between the processing of the file parsing (which occurs in one thread) and the row processing (which occurs in a separate thread) and has been resolved.

Corrections and enhancements made to Outlook meeting requests
Resolved in Pega Version 7.1.8
Using the function 'SendEmailMessage' to send an Outlook meeting request was only generating an email instead of the full meeting invitation. This was traced to unimplemented code and has been corrected. In addition, enhancements have been added to the FormatMeetingRequest RUD to set RSVP options for TO & CC recipients, and the PRODID flag value has been parameterized.

Email Listener performance improved
Resolved in Pega Version 7.1.8
A mismatch in time values was causing Email Listener to be extremely slow in some complex installations. This has been corrected to improve performance.

Eform wizard upload error resolved
Resolved in Pega Version 7.1.8
When attempting to upload a file using the EForm wizard, an error was generated stating "The Flow Action post-processing activity PopulateFileRule failed" and the file did not upload. The root cause of this ruleset problem was that the necessary class was not present in the JAR, and has been resolved.
