The fault monitor process diagnoses errors and checks statistics. The monitor labels an operation successful if the following conditions occur.
The database is online.
The activity check returns no errors.
The test transaction returns no errors.
If an operation fails, the main process checks the action table for an action to perform and then performs the predetermined action. If an operation fails, the main process can perform the following actions.
Restarting the resource on the current node
Restarting the resource group on the current node
Failing over the resource group to the next node on the resource group's node list
These actions execute external programs as separate processes in the background.
The server fault monitor also scans the Adaptive_Server_Log file and corrects any errors that the scan identifies.
