31283 - Lost communication with server

Alarm Group:

HA

Description:

Highly available server failed to receive mate heartbeats.

Severity:

Critical

Instance:

May include AlarmLocation, AlarmId, AlarmState, AlarmSeverity, and bindVarNamesValueStr

HA Score:

Normal

Auto Clear Seconds:

0 (zero)

OID:

eagleXgDsrHaServerOfflineNotify

Cause:

The 31283 alarm presents for nodes in the topology that you should be connected to (for example, not OOS), but that we do not have any TCP links to it over any configured paths. It does not matter why the links were not established (for example, networking connectivity, and node not running, etc.).

Diagnostic Information:

Show the alarms that affect the node's HA score:

iqt -h -fpart,no -fsrcNode,no -fsrcTimeStamp,no -p AppEventLog.0 where "eventNumber in (`iqt -S, -zhp -fnumber AppEventDef where "haScore != 0" | sed -e's/,$//'`)"

Recovery:

1. If loss of communication between the active and standby servers is caused intentionally by maintenance activity, the alarm can be ignored; it clears automatically when communication is restored between the two servers.
2. If communication fails at any other time, look for network connectivity issues and/or it is recommended to contact My Oracle Support for assistance.
