Summary: Change process management of DTM improve HA behavior
Key: TRAFODION-3318
URL: https://issues.apache.org/jira/browse/TRAFODION-3318
Project: Apache Trafodion
Issue Type: Improvement
Components: dtm, foundation
Reporter: Gonzalo E Correa
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.
