Gonzalo E Correa updated TRAFODION-2235:
----------------------------------------
Description:
Certain server and network failures are not detected by the monitor processes
which cause a safety net failure detection mechanism to trigger in all
Trafodion nodes. This safety net mechanism is controlled by the environment
variable SQ_MON_SYNC_TIMEOUT currently set at 15 minutes.
This JIRA is to enhance the node failure mechanism in the Trafodion foundation
components, specifically the monitor process, to detect a non-responsive node
and handle it as a node down condition when a configurable timeout event is
detected prior to the safety net failure mechanism described above.
