>             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

>  Remaining Estimate: 119h
> 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.
