The message below is output when a heartbeat abnormality is detected during heartbeat monitoring of operating systems or servers:
detected an error on the monitored object "server(server identifier name)": no response:ping timeout (MCA00019)
If the heartbeat_error_action parameter in serverIdentifier.conf is set to "message", even if automatic switch/disconnection is enabled and Mirroring Controller is started, automatic switch/disconnection is not performed when a heartbeat abnormality is detected. Therefore, user action will be necessary.
