SSLContext created using protocol from REST connector rule form
Resolved in Pega Version 8.6.1
After upgrading to IBM websphere v9.0.5.6 or higher, API calls Like REST, Connect-HTTP etc were failing to connect to endpoints using TLSv1.2. Investigation showed that although the connector was configured to send TLSv1.2, the ClientHello handshake was triggered for TLSv1.3. Because the SSLContext was created with highest version supported by protocol in the WAS container, this has been resolved by modifying the code to create SSLContext based on the the protocol selected in the REST connector rule form. Additionally, please note that the Connect-HTTP connector has been deprecated and the Connect-REST capabilities in the platform should be used instead.

LookUpList correctly executes during SSO login with model operator
Resolved in Pega Version 8.6.1
After configuring SSO to create operators on fly using a model operator, a new user logging in for the very first time had their operator ID created using the model operator, but after update new users logging in to the system received the error "Only authenticated client may start this activity: RULE-OBJ-ACTIVITY @BASECLASS LOOKUPLIST". This was due to the methods used for additional security on the activity @baseclass LookUpList which allows it to only be run by authenticated users, and has been resolved.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
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.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.6.1
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.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.6.1
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.

Instance count logic updated
Resolved in Pega Version 8.6.1
A performance issue was seen during update that resembled an upgrade hang. This was caused by a combination of incorrect logic in DDLGenerator.getInstanceCountForClass() around counting instances of 'core' classes and all of the site history-data- tables being mapped to the same table that had 1.4+ billion rows. This behavior has been addressed with more correct query logic while performing instance counts. In addition, instance count will be supressed during command line invocations (prpcUtils, platform upgrade).

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.
