Step by Step Demonstrations on Target Blackouts in OEM 13c

So blackouts allow Enterprise Manager administrators to suspend all data collection activity on one or more monitored targets.

The primary reason for blacking out targets is to allow Enterprise Manager administrators to perform scheduled maintenance on those targets so it will not prompt any alerts for a specific time.

It can be defined for the individual target(s) or a group of multiple targets that reside on different hosts, or for all targets on a host.

The blackout can be scheduled to run immediately or in the future and to run indefinitely or stop after a specific duration.

Blackouts can be created on an as-needed basis, or scheduled to run at regular intervals. If during the maintenance period, the administrator discovers that needs more (or less) time to complete maintenance tasks, so we can easily extend (or stop) the blackout that is currently in effect.

Blackout functionality is available from both the Enterprise Manager console as well as via the Enterprise Manager command-line interface (EMCLI).

Here we will be using the Enterprise Manager console and below are activities which we will follow as below mentioned:

1. Create a Blackout

1.a Go to database / instance / target home page and follow as below:

Enterprise >> Monitoring, >> Blackouts.

1.b Click on create

Once click on create follow the next navigation page for blackout schedule and under the Add option search / select target instance/service.

Here we have the option either we can start blackout immediately or start later (Put time frame) and make sure to put duration ample of hours according to activity window or better choose indefinitely.

2. Edit a Blackout:

This is completely optional, in this section we can add more databases/services in the blackout.

Enterprise >> Monitoring, >> Blackouts.

3. View a Blackout

In this section we can view status of blackout.

Enterprise >> Monitoring, >> Blackouts.

4. Delete a Blackout

Finally, it’s time to delete blackout upon successful completion of activities so our jobs/notification/incidents resume for targeted databases/services.

Enterprise >> Monitoring, >> Blackouts
