Data pages explicitly cleared after QP use
Resolved in Pega Version 8.2.5
The Util Node was showing as Offline in the Search Landing Page, and when Jobs were submitted for execution from other Nodes the message "Detected active run with unreachable nodes" was logged. The util node, configured as a backgroundprocessing node, was running QPs, the queue size for custom QPs is 500 messages /queue items per minute, but investigation showed the requestor level and thread level data pages corresponding to the QP activities were not being cleared after use. This led to high heap memory issues that made the node unreachable, and has been resolved by adding code to explicitly remove the data pages when processing has finished.

Custom agent next run time will be rescheduled if the run failed
Resolved in Pega Version 8.2.5
If a customized agent that was set to run every day encountered an exception and failed to run, restarting the agent did not update it to the next run time, it still returned the passed trigger time as its next execution time. This has been resolved with an update that will reschedule the run if the next run time is in the past.

SnapStart supports SAML2 Authentication
Resolved in Pega Version 8.2.5
When using an HTTP Post to SnapStart into Pega using PRCustom style or PRAuth style SAML authentication, the login was looping back to the login request. Investigation showed that the Pega ACS was posting data properly back to the RelayState URL, however the login activity was not getting the SAMLResponse and simply sent a SAML Login Request again. This has been fixed by updating reqContextURI in case of SAML2 Authentication service so pyActivity=value will be passed.

Cookie logging restored
Resolved in Pega Version 8.2.5
As part of security updates, Cookies were restricted from being logged. However, this caused some business use cases such as a custom function call to obtain the list of cookies that are present in the application to stop working. To resolve this, the cookie logging restriction has been reverted.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.2.5
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Column population honors thread count of 1
Resolved in Pega Version 8.2.5
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.

Expired Oauth Refresh Token will persist for obtaining new token
Resolved in Pega Version 8.2.5
OAuth2.0 was providing the refresh token only once in the first time response of the token endpoint. Once the token expired for first time, it was possible to get a new access token using the refresh token. However, if the access token expired for the second time, it was not possible to generate the new access token automatically because the expired token was set as null. To resolve this, the system has been updated to persist the previous refresh token in order to get a new access token.

Run Ruleset Cleanup defaults to true
Resolved in Pega Version 8.2.6
After upgrade, the rule categories and rules were not showing correctly in the App view of the Dev Portal. Many warning messages were also logged related to the Decisioning DM Sample application. This was traced to the rules cleanup script not running properly. While there was a workaround of applying the ruleset cleanup scripts manually after removing the queries that reference the pr_engineclasses table, the cleanup will now be set to run by default (run.ruleset.cleanup=true). In addition, the logic to determine which RuleSets to include has been simplified and most of the pr4_rule_vw deletions have been combined.

Hazelcast upgraded to resolve node startup issue
Resolved in Pega Version 8.2.6
Post data upgrade, the ADM tier failed to start and the error "java.lang.IllegalStateException: Node failed to start!" appeared. This was traced to a dormant bug in Hazelcast 3.11 that caused starting nodes to fail when the Hazelcast master node was shutting down, which was exposed by recent Pega changes made to enable parallel restarts of nodes in Cloud environments. Hazelcast delivered a fix for the parallel restart problem and the hotfixed jar has been merged into the platform. In addition, previous logic for loading Admin Studio waited 30 seconds before timing out when fetching information for each node. This caused issues with large clusters and Admin Studio not loading. The logic has been updated in the Admin Studio UI to load the page despite delays/issues waiting for nodes to respond to the gathering of cluster data, and the algorithm to detect remote-call timeout has been updated and is applicable to batch operation.
