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.

INC-174298 · Issue 650257

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).

INC-180479 · Issue 659640

DSS partition count setting made backward compatible

Resolved in Pega Version 8.6.1

After update, the DSS to limit the number of partition counted was no longer working and instead used the default value of 20. This has been corrected and made backwards compatible.

SR-113714 · Issue 173122

Added tenantID checking for multi-tenant import of access groups

Resolved in Pega Version 7.1.7

When attempting to overwrite an existing access group by importing the Client Access groups in the tenant layer, an error was generated and the access groups were not overwritten. This occurred when the SQLs were not Tenant-qualifying for operator records but were being imported into a tenant; as a result, operator record updates were marked as inserts. To correct this, the behavior has been updated to query for current tenantId and always tenant-qualify the query if it's an overridable instance and not in a shared context.

SR-114353 · Issue 166997

System scanner performance enhanced

Resolved in Pega Version 7.1.7

When working with a large number of hotfixes, the system scanner can become very slow. Performance enhancements have been incorporated to increase speed by changing how ID and key comparisons are performed.
