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).

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.

Added check for naming conflicts when upgrading Oracle
Resolved in Pega Version 7.2
When attempting to upgrade a single schema on Oracle database, running the generateddl script failed with a NullPointerException. This was caused by database tables which had a column name called 'SYS_ID' as part of the primary key. Since Oracle uses system-generated names beginning with "SYS_" for implicitly generated schema objects and subobjects, Oracle discourages the use of this prefix in the names explicitly provided to the schema objects and subobjects in order to avoid possible conflicts in name resolution. To resolve this, a tester has been added to the system to check for this naming use and issue a warning.

Documentation added on adding Tomcat-on-Oracle Rules resource
Resolved in Pega Version 7.2
The Tomcat-on-Oracle installation guides for Pega ML7 and ML8 did not contain instructions for adding a for jdbc/AdminPegaRULES. As such if the installer prepared a two-user (Base + Admin) setup in the database and allocated the Base user to jdbc/PegaRULES, the Pega platform was unable to run DDL to create new tables for new work types and new data types, as the installer has not configured the additional datasource to use the Admin user. The documentation has been updated to add the necessary step between Steps 1 and 2 of the "Create a JDBC Datasource" chapter (page 41 from the ML7 installation guide).

Documentation updated to reflect change to read-only getProperty pages
Resolved in Pega Version 7.2
In recent versions of the system, getProperty() was modified to support the creation of a property on a read-only page. However, even though the property has been created, it is not possible to set its value. This was not clearly indicated in the documentation, and read-only exceptions were being generated when putString() or setValue() attempted to give a value for the property on a read-only page. The documentation has been updated to clarify this use case.
