If a database transaction fails, the server fault monitor performs an action that is determined by the error that caused the failure. To change the action that the server fault monitor performs, customize the server fault monitor as explained in Customizing the Oracle 9i RAC Server Fault Monitor.
If the action requires an external program to be run, the program is run as a separate process in the background.
Possible actions are as follows:
Ignore. The server fault monitor ignores the error.
Stop monitoring. The server fault monitor is stopped without shutting down the database.
Restart. The server fault monitor stops and restarts the Oracle 9i RAC server resource.
