Null check added for step page
Resolved in Pega Version 8.3.6
After creating and adding new Access Roles and application 'Access When' to the privileges instead of Production level, during run time the error "runtime.IndeterminateConditionalException: Trying to evaluate Rule-Access-When conditions L:IsProdAccess when there is no page to evaluate them against" appeared for the specific privileges. This was traced to a missed use case where the system falls back to the step page if the page for evaluating the 'when' condition is null, which did not account for scenarios where the step page can be null. To resolve this, a null check has been added which will fetch the primary page if the step page for the access 'when' condition is null.

Improved disconnected requestor cleanup for FieldService
Resolved in Pega Version 8.3.6
A large number of requestors from FieldService with the status as 'Disconnected' were accumulating and causing performance issues. This was traced to the requestors not getting passivated due to users not logging out and new requestors being created for the same users next time, and was caused by the value of the DSS Initialization/PersistRequestor being set as "OnTimeout". When the DSS prconfig/timeout/browser/default is not configured, the default browser requestor timeout is 60 minutes. In this scenario, requestors were not passivating as the requestor passivation timeout was set to the refresh token lifetime for mobile users, which was very large and overwrote the DSS value. This has been resolved by removing the code which set the passivation timeout to the OAuth2 refresh token lifetime.

Updated upgrade handling for migrating work objects
Resolved in Pega Version 8.3.6
After upgrading from Pega 6.2 to 8.3, the work migrated work objects were missing SLAs due to missed entries in the assignment tables (PC_ASSIGN_WORKLIST/ PC_ASSIGN_WORKBASKET) . The SLA was firing, but the processing failed due to the fact the runtime could not resolve a 'AddHistoryPage' library function. In this case, multiple upgrades of the application dating back to Pega 4 resulted in the runtime context containing older ruleset versions in higher ruleset versions, hiding the underlying Pega 8 version of the rule. For releases prior to Pega 7.3, Rule-Application was stored in pr4_rule and will be migrated to pr4_rule_application during upgrades. However, since Context Upgrade is run before Optimize Newly Exposed Columns, the pyDependsOnName won't always be populated. To resolve this, the system will filter based on the value in the blob rather than the exposed column so there will be a value regardless of the upgrade-from version.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.3.6
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

Repaired Tracer use with Google Chrome
Resolved in Pega Version 8.5
After running Tracer while using Chrome, closing it and trying to run another resulted in an error indicating "Cannot Launch multiple tracer sessions for a requestor". This was identified as a bug with Google Chrome Versions greater than 70 and was caused by Chrome deprecating the use of sync XHR on page dismissal, and has been resolved by modifying the system to use a beacon API instead.

database locking improved for login performance
Resolved in Pega Version 8.5
A slowness issue seen when trying to login to my.pega.com was traced to numerous database locks occurring on the pr_data_saml_authreqcontext table during the SAML flow. Analysis showed that while running Obj-Save on AuthRequestContext with 'OnlyIfNew' as false, the check caused a select query to run on the table to determine if the context was already there and insert it if it was not. To resolve this, the onlyIfNew check will default to true to avoid running the query; if the context is already present it will be overridden. Duplicate key exception handling has also been added to avoid any issues if a resave is done with same key.

CDK key loading modified for better database compatibility
Resolved in Pega Version 8.5
Users were unable to log on to the system and received the error "There has been an issue; please consult your system administrator." Investigation showed the log errors stating "(dataencryption.DataKeyProvider) ERROR localhost - Could not get CDK from systemKeyManagementCache - System CDK is null". This was an issue specific to the MS SQL Server database when there were 6 or more CDKs in the database: CDK keys are loaded from database into Cache using an SQL statement which had the ORDER clause. By default, the ORDER clause treats NULL values differently on different databases, and this caused MS SQL databases to not load a necessary CDK key. To resolve this, the SQL query has been modified so the result will be the same for all supported daatbases (Oracle, Postgres & MS SQL Server).

Resolved OAuth2 mobile app loop
Resolved in Pega Version 8.5
When a Pega OAuth2 authorize endpoint was invoked and the redirect URI contained "app", a loop was created where the system attempted to fetch the app alias from the state parameter value and was redirected back to itself. This could sometimes result in inconsistent mobile app styling. Investigation showed that a certificate with keyword app that was picked for the redirect URI could have the key word assumed to be the app alias context, so a workaround was to remove the app keyword. To resolve the issue, the system has been updated to look for the app alias only in the state parameter rather than performa a string contains check on the entire query string.

OKTA receives parameters on logout
Resolved in Pega Version 8.5
When using an OIDC logout endpoint with a parameter set as a data page value, the data page retrieved the ID Token from the database, but when logout was clicked the datapage name was being displayed in the browser instead of the IDToken. To resolve this, code has been added to support sending ID token parameters for logoff endpoint for OKTA logoff using OpeniD connect.
