Lou DeGenaro commented on UIMA-6037:
------------------------------------
Presently, autostart.py employs
org.apache.uima.ducc.database.lifetime.DbDaemonLifetimeUI --query to inquire of
the database what daemons should be running where, and parses this information
to determine what daemons should be running locally. It then proceeds to start
any daemons that should be running locally if not already running by using
ducc.py (for agent) or ducc_start for head node.
Note that employment of DbDaemonLifetimeUI requires use of DB password located
in ducc.private.properties.
> agent autostart should rsync its local ducc_runtime tree
