Caution  -  Before you customize the HA for Oracle Database server fault monitor, consider the effects of your customizations, especially if you change an action from restart or switch over to ignore or stop monitoring. If errors remain uncorrected for long periods, the errors might cause problems with the database. If you encounter problems with the database after customizing the HA for Oracle Database server fault monitor, revert to using the preset actions. Reverting to the preset actions enables you to determine if the problem is caused by your customizations.
