Performance improvements for revalidate and save
Resolved in Pega Version 8.7
In order to improve performance when working with very large numbers of class definitions, an update has been made to optimize the revalidate and save process by avoiding looking up all classes on the system instead using ClassDefinition for existence and checking ancestor data to ensure class is a Rule- or Data- descendant.

Database primary keys generated as NONCLUSTERED for imports
Resolved in Pega Version 8.6
When a primary key was defined for a table and the table was exported and then imported, the primary key was generated as CLUSTERED. This resulted in an MS SQL Cluster Index violation because all Pega-shipped tables generated during installs/upgrades have a PK constraint index with NONCLUSTERED index type as it allows for a longer key. This was a missed use case, and has been resolved by updating the system such that when importing with MS SQL database, the primary key index is made NONCLUSTERED all the time so it will be consistent with the base platform.

Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.6
Unwanted optimization was automatically added to properties for the Application-Work-Casetype class created using the wizard in the App Studio. Attempts to remove the optimization did not work: the property advance tab was showing the optimized classes details even after deleting and recreating the property. When a property is optimized the system adds entries to pr_changelog for the list of classes it has optimized. When the property was deleted, the pr_changelog was not cleared. This was a missed usecase, and has been resolved by overriding the Cleanup activity at Rule-Obj-Property class to delete the pr_changelog entry associated with that if it is present.

Installer files updated with class loader conflict resolution assistance
Resolved in Pega Version 8.2.4
When sending emails with attachments, errors were observed relating to a loader constraint violation indicating that when resolving interface method, the class loader of the current class and the class loader for the method's defining class had different Class objects for the type used in the signature. The resolution for this requires user configuration of the app server, and the following files for the install guide have been updated with the appropriate information:Deployment-guides-dita/install.ditamap Deployment-guides-dita/Content/Topics/app-server-config/creating-jdbc-driver-module-jboss-tsk.dita Deployment-guides-dita/Content/Topics/app-server-config/delegating-javax-activation-to-JRE-loader-tsk.dita

Kerberos handling updated for database remap
Resolved in Pega Version 8.6
After upgrade from Pega v7.2 to Pega v8.4, using Kerberos authentication was failing during the remap task. Investigation showed that null username and password values were being passed to SchemaAssignmentUtility along with the flags as arguments, causing the utility to misinterpret the arguments. As arguments should be populated only when flags and values are available and not null, an update has been made which will set the username and password flags only if they are not null in the Remap database tables target.

APIs updated for sending large attachments with MSGraph
Resolved in Pega Version 8.7
Sending mail using MSGraph was failing with the exception "Error during http request" when attachments were greater than 3MB. This was traced to changes made by Microsoft in the Graph API implementation which caused it to throw a runtime exception instead of the expected 413 status code and relevant message for the attachment size. To resolve this, an update has been made to ensure that any attachment larger than 3MB is sent via the Microsoft Outlook API.

prproductmigration build.gradle updated for new mime4j asset name
Resolved in Pega Version 8.2.4
While running the getMigrationLog for ProductMigration script provided in the Pega 8.2.2 media files, errors appeared referencing "NoClassDefFoundErrors when running getLogs". This was caused by the referenced class not being found on the classpath: the version of the included jar did not include the class needed due to Praxiom's default version being updated to use a new version of mime4j that required an asset name change. To resolve this, the mime4j asset name in prproductmigration build.gradle has been updated to pick up the correct version of the dependency for Praxiom.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.7
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Pega Catalog custom upload control modified
Resolved in Pega Version 8.6
Attempting to upload a catalog.zip file caused the system to hang and thread dumps were seen in the logs. Investigation traced the issue to the custom control used to upload the catalog, which was posting the entire content in form data rather than sending a multi-part request. The control contained both legacy code which used form.submit() and encoding along with new code that used SafeURL and sent an async request. With this, encoding could not be set to multi-part in case of an AJAX request. To resolve this, the catalog upload control has been modified to use the appropriate legacy code that performs form.submit() and sets the encoding properly.

DSS partition count setting made backward compatible
Resolved in Pega Version 8.7
After upgrade, the DSS 'dsm/services/stream/pyTopicPartitionsCount' used to limit the number of partitions was no longer working and instead used the default value of 20. This has been corrected and made backwards compatible.
