[jira] [Updated] (TRAFODION-2235) Enhance node failure detection
and coordination
[ https://issues.apache.org/jira/browse/TRAFODION-2235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
