Faults Detected by the MaxDB Fault Monitor

The MaxDB fault monitor detects the following faults in MaxDB:

• A status of the MaxDB database instance that is not ONLINE, for example, OFFLINE or ADMIN

• Unexpected termination of the parent kernel process of the MaxDB database instance

The MaxDB fault monitor also detects the unavailability of SAP xserver. This fault monitoring supplements the fault monitoring that the SAP xserver fault monitor provides.

If the MaxDB fault monitor detects that SAP xserver is unavailable twice within the retry interval, the MaxDB fault monitor restarts MaxDB. By restarting MaxDB, the fault monitor ensures that the MaxDB database fails over to another node when SAP xserver is persistently unavailable.
