Correct. Most DUCC daemons running on the head node are restartable. We
expect to complete this work so that in the case of head node failure a new
head node can automatically be started.
Currently DUCC can be configured such that no active user work is affected
if a head node goes down. However, without the head node no new user
processes are created.

Hi,
I have a question. If head node fails then we are no more able to do UIMA
processing. Can I defined multiple head nodes in DUCC? If one head node is
failed then second node will work as a head node. Is this possible? what is
the backup strategy of DUCC?

Hi Eddie,
Sorry I did not get you. What do you mean by this, "Currently DUCC can
be configured such that no active user work is affected if a head node
goes down. "?
As I understand if a node goes down or crashed then all the processes
which are running on this node will terminate. So, big question is, "How
DUCC ensures no active user work is affected if head node goes down?"
