Handling added for runtime exception on upgrade due to inaccessible external schema mapping
Resolved in Pega Version 8.1.6
If a system used external schema mapping, attempts to upgrade were failing with the error "Caused by: com.pega.pegarules.pub.database.ConfigurationException: Unable to obtain data source "java:comp/env/jdbc/PegaRULES", as it is undefined". This was traced to configuring external DADNs which were not accessible from the server where the upgrade was being run: an upgrade will fail if it cannot connect to an external datasource even if no changes need to be made to that datasource. However, because a PRRuntimeException was unexpectedly being thrown instead of a Database Exception, the exception was not properly caught and handled. This has been corrected.

Support added for custom JVC arguments for Cassandra
Resolved in Pega Version 8.1.6
An enhancement has been added to support specifying custom JVM arguments for Cassandra. This allows uses such as enabling GC logging for cloud deployments, or to increase the native transport queue size for read-heavy deployments.
