Support added for email addresses with hyphen in domain name
Resolved in Pega Version 8.3.5
When attempting to enter a email with a hyphen '-' in the domain part of an email ID ([email protected]), the reply button was getting disabled. This was caused by the regex validation implemented in the "pzValidateEmailAddress" (Work-Channel-Triage-Email) standard activity not covering all the possible cases. To resolve this, regex has been changed to instead use a platform-provided rule to ValidateEmailAddress.

Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.3.5
Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.

Resolved Cassandra query read/write latency
Resolved in Pega Version 8.3.5
Read/write latency was seen when certain Cassandra queries were triggered by the system. This was traced to an unusual case where a flush was not done for an exceptionally long time period, and has been resolved.

Handling updated for social messaging items with very large embedded images
Resolved in Pega Version 8.6.5
Job scheduler was running out of memory while handling large/multiple files, causing nodes to crash while handling Social Messaging items. Inline images were also not being sent in the ACK email. Investigation traced this to a custom job scheduler and activity used to create PDFs from email communication and send the PDFs to a third-party system. This used the standard Email Triage/PegaSocial functionality for the emails, which were stored as instances of PegaSocial-Message. The custom Job scheduler and activity then leveraged the Data Page D_pxEmailPosts to retrieve the emails in order to harvest the text from the emails. The issue occurred when a number of the emails had multiple or large embedded images in them, meaning the PegaSocial-Message instances are very large. This resulted in the node running out of memory and crashing. To resolve this, code has been added to support inline images in ACK email and the complete message from Pulse will be used instead of the original message as the email body for the ACK email.

UpgradeInteractionCase modified to update work page on save
Resolved in Pega Version 8.6.5
After update, service cases were failing to unpend when using a custom data transform that accessed the D_CorrespondenceCase data page. Investigation showed the D_CorrespondenceCase data page was internally using the D_pxGetInteractionCaseDetails data page; this call upgraded and saved and committed the case but this commit released the lock which the custom data transform had acquired. Because this happened before accessing the CorrespondenceCase datapage, it led to an error while committing the service case details. To resolve this, the postprocessing activity "pyUpgradeInteractionCase" of D_pxGetInteractionCaseDetails has been modified to write the update on the work page as soon as a save is performed.

Enhanced SSA metrics made available
Resolved in Pega Version 8.6.5
In order to better diagnose delays related to the time when a Campaign is scheduled to start and the time when the Dataflow actually starts to run, an update has been made which will generate detailed metrics to cover some of the strategy execution key performance intensive areas. Additional lower level internal metrics related to SSA engine execution have also been made available by way of a DSS to collect more runtime insight for diagnosis. To enable the collection of these Level 2 SSA internal metrics, set the dataflow/shape/strategy/detailed_metrics/level2 DSS in the Pega-DecisionEngine rule set to 'true'. A comprehensive set of enhanced metrics will be available in Pega 8.8.

Updated context handling for executing data transforms in dataflows
Resolved in Pega Version 8.6.5
When performing a sort operation in a data transform on a page list and invoking the Data transform through a Data flow, a java.lang.UnsupportedOperationException was generated on the sort step even though the data was correct. Investigation showed that the dataflows were using a different execution context than the context used for regular activity execution. An update has been made to ensure the correct context is being used while executing data transforms in dataflows.

Explicit Kerberos renewal added for HDFS
Resolved in Pega Version 8.6.5
When using WebSphere/IBM with Hadoop connectivity, the Kerberos credentials were expiring after 7 days and causing connectivity failures. Investigation showed the Apache Hadoop HDFS Client was not renewing the ticket even when there were operation calls every few hours. To resolve this, an enhancement has been added to the Pega HDFS client which will explicitly tell Hadoop authentication layer to check for Kerberos ticket renewal instead of relying on Hadoop built-in logic.
