How to Set Blackout in OEM 13c: A Comprehensive Guide

Oracle Enterprise Manager (OEM) 13c offers robust capabilities for managing your Oracle database environment. One such feature is the ability to set blackouts, crucial for planned maintenance or upgrades. This guide will walk you through the process of setting blackouts effectively in OEM 13c.

Understanding Blackouts in OEM 13c

Before diving into the process, let's clarify what a blackout is. In OEM 13c, a blackout represents a scheduled period during which monitoring alerts are suppressed. This prevents your monitoring system from being flooded with alerts related to planned activities, such as patching or upgrades. This is vital to avoid alert fatigue and ensures you only focus on genuine issues after the blackout period ends.

Key Benefits of Using Blackouts:

• Reduced Alert Fatigue: Prevents alerts from overwhelming your monitoring system during planned maintenance.
• Focused Incident Management: Enables you to concentrate on unplanned issues without distraction from expected alerts.
• Improved Operational Efficiency: Streamlines maintenance processes and minimizes disruption.
• Enhanced Monitoring Accuracy: Prevents false positives stemming from expected changes during scheduled tasks.

Step-by-Step Guide to Setting a Blackout in OEM 13c

1. Log in to OEM 13c: Access your OEM 13c console using your appropriate credentials.

2. Navigate to the Target: Locate the specific database instance or target for which you want to set a blackout. This could be a database, host, or other monitored component.

3. Access the Blackout Settings: The exact location of the blackout settings might vary slightly based on your OEM 13c version and configuration. However, you'll generally find it within the target's monitoring settings or maintenance options. Look for an option labelled "Blackouts," "Scheduled Maintenance," or something similar.

4. Create a New Blackout: Once you've found the appropriate section, click on a button to "Create Blackout" or similar. You'll be presented with a form to configure the blackout settings.

5. Configure Blackout Parameters: You'll need to specify the following:

   • Start Time and End Time: Precisely define the blackout's duration. Make sure to use the correct time zone.
   • Description: Add a clear and descriptive title explaining the reason for the blackout (e.g., "Database Patching," "Hardware Upgrade"). This is crucial for auditing and troubleshooting.
   • Affected Targets (If Applicable): Depending on your setup, you may need to select the specific targets affected by this blackout.
   • Alert Suppression: Verify that alert suppression is enabled during the specified period.

6. Review and Save: Carefully review the settings before saving. Incorrectly configured blackouts can lead to missed critical alerts outside the intended window.

7. Verification: After saving, check your blackout schedule to confirm that the blackout has been successfully created.
