> Change process management of DTM to improve HA behavior

> Key: TRAFODION-3318

> Project: Apache Trafodion
> Issue Type: Improvement
> Components: dtm, foundation
> Affects Versions: 2.4
> Reporter: Gonzalo E Correa
> Priority: Major
> Fix For: 2.4

> Original Estimate: 120h
> Time Spent: 3h

>
> Current process management model for process type DTM enforces and soft node
> down behavior which kills all processes in a node where a DTM process
> terminates abnormally. The DTM process is recreated by the monitor along with
> all persistent processes hosted in that node.
> To reduce the fault zone impact, this change removes the soft node down/up
> functionality so that the DTM process is recreated without killing all other
> processes in the node. The rule where the persistent DTM process cannot be
> restarted within the configured retries in the specified time window will
> cause a node down will still be enforced.
