Duplicate Checking
By saving history for your alerts, you can define Oracle Alert to check for duplicates - that is, exceptions that existed in your database during a previous alert check. You can define Oracle Alert to perform alert actions when it finds these duplicate exceptions in your database. With duplicate checking, you can monitor outstanding items in your database until they are resolved. You can spend your time handling important business events, instead of following up on outstanding issues.
Checking for Duplicates
To check for duplicates:
Note: You need to save history for your alert for at least one day longer than the frequency of the alert if you want to use duplicate checking. Oracle Alert cannot check for duplicates if history for the previous alert check is not retained. If you are defining a response set for your alert, save history for the number of response days in addition to the number of days you want to retain history.
3. Check the Check For Duplicates check box if you want Oracle Alert to consider an output's exception value when it checks for duplicates.
To check for duplicates at the action set level:
2. You can customize the duplicate configuration of each action set by checking the Check for Duplicates field for each output in the Outputs alternative region of the Action Sets window.
Note: Each action set duplicate configuration takes precedence over the alert duplicate configuration during an alert check.
1. To flag for duplicates and have Oracle Alert perform a different detail action each time it finds the same exception during an alert check, you need to customize your alert to use a feature called action escalation. See: Action Escalation.
2. If you want Oracle Alert to perform the same detail action each time it finds the same exception during an alert check, you need to turn off duplicate checking by unchecking the Check for Duplicates check box in the Alert Details window and in the Action Sets window of the Alerts form.
1. You can flag duplicate exceptions within summary messages by specifying that you want to suppress duplicates at the action set level. When it sends the summary message, Oracle Alert includes the duplicate exception in the summary message, but flags each duplicate exception found with an asterisk (*).
2. To suppress duplicates at the action set level, check the Suppress Duplicates check box in the Action Sets window of the Alerts form.
