SR-D46536 · Issue 515794

Custom agent next run time will be rescheduled if the run failed

Resolved in Pega Version 8.4

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.

Hazelcast upgraded to resolve node startup issue

Resolved in Pega Version 8.4

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.

Requestor information restricted to improve security

Resolved in Pega Version 8.4

An intermittent issue was seen where User1 would log in and User2 would then log in and see the data/profile of User1. This was traced to an exception in the session logic which prevented the previous requestor ID from being cleared, causing it to then be mapped to the second user. To correct this, WebStandardImpl has been updated to restrict the requestor information in the session object and in the HTTP API while retrieving the requestor.

Local UUID cache will be updated when merge event is detected

Resolved in Pega Version 8.4

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.

XSS protection added to layout runtime java and whitelist validation available for host/XFHost

Resolved in Pega Version 8.4

In order to protect against XSS issues, filtering has been added to the RepeatDynamicIndex parameter value in layout runtime java. In addition, a validation for X-Forward-Host value has been added which will be read from a local configuration. This is in the form of a white list regex filter for the host/XFHost header to ensure the URL's actions cannot be redirected.

SR-D54319 · Issue 532529

API added to sync presence with requestor to clear inactive operator sessions

Resolved in Pega Version 8.4

An intermittent error message was seen indicating the maximum number of active sessions for the current operator had been reached even though there were not multiple logins and there was no requestor displayed in the requestor management landing page. This was traced to sessions that were not properly closed and cleared, and has been resolved by exposing an API that will sync the presence record with the requestor state so inactive sessions will be cleared.
