The following example demonstrates how to set the resolution state of database monitoring alerts in the Operations Manager database. The example selects only those alerts that are related to the database's availability health. The example then checks the resolution state of each alert that is found; if the resolution state is not already set to "Closed," the example changes the alert's resolution state and adds a comment to the alert's history.
