Kerberos handling updated for database remap
Resolved in Pega Version 8.4.5
After upgrade from Pega v7.2 to Pega v8.4, using Kerberos authentication was failing during the remap task. Investigation showed that null username and password values were being passed to SchemaAssignmentUtility along with the flags as arguments, causing the utility to misinterpret the arguments. As arguments should be populated only when flags and values are available and not null, an update has been made which will set the username and password flags only if they are not null in the Remap database tables target.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.4.5
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Query added to find time zone for MSSQL database
Resolved in Pega Version 8.4.5
The exception "com.microsoft.sqlserver.jdbc.SQLServerException: xp_regread() returned error 5, 'Access is denied.'" was generated when the AES agent PushDBSizeInfo was being run. This was traced to the GetDBInfo activity trying to retrieve the time zone of the MSSQL database by executing a query that used a Microsoft SQL routine to read the windows registry to get the current time zone. The error was not due to security within the SQL Server, but instead was caused by Microsoft Windows security related to the permissions on the registry keys for the users under which specific SQL Server processes were running. To resolve this, an update has been made to call a different query which will get the time zone for the SQL Server.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.4.5
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

White list filter added for X-Forward-Host value security
Resolved in Pega Version 8.3.2
In order to improve security, 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.

Query parameters will be cleared after redirection from authentication
Resolved in Pega Version 8.3.2
When using the /PRAuth Servlet, running a snapstart URL generated from a secondary application correctly executed SAML Authentication and Pega processing, but a second URL generated with different parameters ran with the parameters from the first request. The third and subsequent requests processed as expected with the parameters sent in with the request. Investigation showed that the previous parameters were picked due to the query string parameters not being cleared after redirection, and this issue has been resolved by updating the system so it will clear the parameters after issuing a redirect from the authentication policy engine.

Updated HotFix Manager for use in older versions
Resolved in Pega Version 8.3.2
The DL logic in Hotfix Manager was changed in 8.3 to include the catalog of all framework changes. This had the unintended side effect of preventing DLs from being installed in Pega 7.3.1 and lower versions as the versions included in the catalog are not present on those systems and the validation failed. This has been resolved by revising the DL update so the system will only add all apps to the catalog for platform 7.4+ DLs.

Colon in folder or file name will be replaced with underscore during unzip
Resolved in Pega Version 8.3.2
After creating a product file (zip), attempting to import the same file into an updated system resulted in an exception. Investigation showed that in this case the zip file was a Product rule form which had applications packaged with a colon(:) in the name of the application, a format that was allowed in 6.x versions. Because Windows machines restrict creating creating any folder or file with : in its name, the zip file could not be inflated as part of the import process. To resolve this, the system has been updated so that a colon(:) will be replaced by underscore(_) during inflate operations.

Custom agent next run time will be rescheduled if the run failed
Resolved in Pega Version 8.3.2
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.
