Personalized table sort order limited
Resolved in Pega Version 8.5.4
After implementing a personalized table, the query started adding more 'order by' sorts, causing system impact. This was traced to the pzPopulateSortOrder activity Implementation having different constants assumed for the same purpose (999 in one place and 99999 in another), and has been resolved by updating the logic in step 1 and step 2 to disregard sort orders higher than 999.

Updated authentication for report filter screen
Resolved in Pega Version 8.5.4
If the report filter screen was shown first after clicking on the report link in the report browser, an error is generated for users but not for administrators. This has been resolved by registering the activity and adding a BAC registration section to the prompt filter section.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.5.4
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 8.5.4
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 8.5.4
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 8.5.4
A performance issue was seen during upgrade 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).

Elasticsearch will split queries to avoid URL length limits
Resolved in Pega Version 8.7.2
Elastic Search Functionality was not working and showed the status as Offline. Investigation showed that when an external Elasticsearch setup had an index prefix length = 200 and a large number of dedicated indexes, the error "too_long_frame_exception, reason: An HTTP line is larger than 4096 bytes" was generated. In this case, the system was working with approximately 87 dedicated indexes and the name for each of them was sent over the URL, resulting in this error message. This has been resolved by updating the system to split queries so as to not exceed the HTTP line limit in Elasticsearch.

Updated variable handling for filter logic to avoid reuse
Resolved in Pega Version 8.7.2
When adding the property "ItemStatus" as a filter for a report, the validation message: "This property does not exist or has no column mapping" appeared. This was traced to an empty caption for a class join property used in the filter due to RRFilters_Logic reusing the strFieldName variable, and has been resolved by updating the variable handling to use a unique name, strPropName.
