SAS^® Real-Time Decision Manager and SAS^® Decision Manager use SAS Decision Services to activate and run flows (decision campaigns). When you activate a SAS Decision Services flow that contains an activity, SAS Decision Services publishes the activity code to the SAS^® Federation Server. This publishing step is performed by a stored process that runs in the SAS Workspace Server. If the SAS Object Spawner or SAS Workspace Server are unavailable when you activate the flow, then the activity code for that flow is never published. When this problem occurs, SAS^® Management Console indicates that a problem was encountered on the server, but gives no details. The flow is activated, but produces errors when it executes. The following error is written to the SAS Decision Services engine server log during the publishing step:

...ERROR  com.sas.rtdm.implementation.EngineManager - Error Synchronizing cache.
com.sas.analytics.ph.RTDMException:
com.sas.services.connection.FatalConnectionFactoryException: The application
could not log on to the server "heslax3.unx.sas.com:8701". No server is
available at that port on that machine.

To work around the issue, deactivate the flow that contains the unpublished activity. Check that the SAS Object Spawner and SAS Workspace Server are available. Reactivate the flow. The activity is published when the flow is reactivated.

Starting in release 6.3, SAS Decision Services attempts to publish any unpublished activity each time the SAS Decision Services engine server synchronizes with the SAS^® Metadata Server.
