Retry logic added for downloading upgraded rules
Resolved in Pega Version 8.2.8
A Rules upgrade failed while downloading applications from the maintenance server due to an SFTP server connection failure. This has been resolved by adding logic to retry if the first connection attempt fails.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.2.8
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved
Resolved in Pega Version 8.2.8
During index name generation, the algorithm that was responsible for index name uniqueness was sometimes insufficient and cerated a loop condition. This has been resolved by using a stronger hash algorithm and refactoring the code that could result in a loop.

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

Added timeout handling for non-PRAuth servlets
Resolved in Pega Version 8.2.4
After logging in via external authentication service (SAML Single Sign On) and setting up a timeout in the access group RuleForm, when the user performed any action and the server identified the request to be timed-out, it was expected that a SAML request would be sent from the browser to the external Authentication Server (referred as IDP) and the flow would proceed from there. This worked as expected for a non-AJAX request. To resolve this, handling has been added for timeout when using non-PRAuth authentication services.

SAML data pages restored after passivation
Resolved in Pega Version 8.2.4
If login used SAML SSO, resuming the session after passivation resulted in missing or empty data pages when using an SAP integration with Pega Cloud. This was traced to a security change that modified the D_SAMLAssertionDataPage and D_SamlSsoLoginInfo data pages as readonly, causing them to not be passivated under these conditions. To resolve this, the data pages have been made editable so they will be restored as expected. This change also resolves any difficulty with SAML logoff activities in conjunction with SAP and Pega Cloud.

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.

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.

Data pages explicitly cleared after QP use
Resolved in Pega Version 8.2.6
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.

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.
