Handling added for using virtual network interface for Stream Services startup
Resolved in Pega Version 8.6.3
After update, the restart of any node failed with the error "Unable to create DSM service DATA-DECISION-SERVICE-STREAMSERVER DEFAULT". This has been resolved by adding support for allowing stream service to start on the virtual network interface in cases where it was explicitly configured via the "cluster/hazelcast/interface".

Updated background refresh for off-screen worklist
Resolved in Pega Version 8.6.3
After update, performance impacts were seen on the field service mobile app. This was traced to Worklist refresh, and has been resolved by adding an update which will postpone the refresh when the worklist webview is in the background (not visible on the screen).

Check added to disable offset support for older versions of Oracle
Resolved in Pega Version 8.6.3
An ORA-00933 error was generated after upgrading from Pega 7.1 to Pega 8.5. This was traced to a conflict between Oracle 11g and the Pega 8.5 platform related to an OFFSET statement being added to a query for a version of Oracle that doesn't support it. The preferred solution is to upgrade Oracle to address this, but in order to support backwards compatibility a check has been added which will disable offset support in Oracle if productversion <=11.

Database Transaction Log update overflow resolved
Resolved in Pega Version 8.6.3
When automatic.resume=false was encountered uring an update, cleaning up the existing codeset from previous updates ended up filling up the database transaction logs and caused the update to fail. This has been resolved by updating the process of clearing the codeset so it doesn't overflow the transaction log.

Restored local blocking queue cache
Resolved in Pega Version 8.6.3
After update, it was not possible to bring up secondary VBD nodes after restarting. Investigation traced this to earlier work done to resolve a memory leak issue, in which stale entries for local blocking queues were removed from cache. This resulted in modifying the queue listener logic to use "cache.getQueueIfPresent(jobId)" instead of "cache.getQueue(jobId)". Because the listener was not creating the cache if it was not present and the cache which held the local blocking queue didn't have the entry for the current remote execution job ID, the caller of the remote execution on Node2 ended up in blocking state forever, waiting on the local blocking queue. To resolve this, the code has been updated to ensure the blocking queue is created and stored in the local queue cache before publishing the remote job message.

Catch added for missing DelayedItemsDataFlowService run options
Resolved in Pega Version 8.6.3
The exception "Caused by: java.lang.IllegalStateException: Loaded a work object [DelayedItemsDataFlowService] while no run config was present" was logged while initializing the DelayedItemsDataFlowService, causing a shutdown. Investigation showed this was caused by corrupted data in the database post update, where the database was missing a row in pr_data_decision_ddf_run_opts representing the run options of 'DelayedItemsDataFlowService' while the work object record was present in the database. To resolve this, an update has been made to catch exceptions generated by DataFlowService and report them as logs and alert. This will prevent the startup task from failing and stopping the process.
