Overview of Summary Threshold

Oracle Alert can automatically determine whether to perform a detail or summary action, depending upon the number of exceptions found by the alert Select statement. If you define a summary threshold, Oracle Alert performs a detail action for each exception found by the Select statement, but if the number of exceptions found exceeds the summary threshold, Oracle Alert performs a summary action. You need to first define a detail and a summary action, include them in a threshold group, and then specify a summary threshold.

You may find that defining a summary threshold is useful for your alerts that return varying amounts of data from your database. If your alert typically returns few exceptions, but on occasion returns many exceptions, Oracle Alert can automatically switch from performing a detail action for each exception to performing a summary action for each group of exceptions. Oracle Alert performs the most efficient alert action automatically, without requiring further intervention from you.
