Updating Always-On Monitoring

In order to carry out the notification function of Enterprise Manager, Always-On Monitoring requires target monitoring and administrator notification configuration data to be synchronized with the Enterprise Manager repository. Full synchronization is performed when you install Always-On Monitoring and run the following command:
$AOM_HOME/scripts/emsctl sync

Incremental synchronization must be performed thereafter in order to keep Always-On Monitoring monitoring/notification configuration current.

The following changes to Enterprise Manager will require an incremental Always-On Monitoring synchronization:

  • New hosts (Agents) added

  • New targets added

  • Changes to downtime contacts

  • Changes to administrator email addresses

  • Changes to email server configuration

Always-On Monitoring stays in SYNC with Enterprise Manager automatically via an incremental synchronization job that runs every 24 hours. You can change the synchronization interval using the emsctl update_task command.

$AOM_HOME/scripts/emsctl update_task -task_name=<SYNC|PURGE> -run_interval=<time in minutes between task executions>

Incremental synchronization can be run manually via the emsctl sync command.

Running an Incremental Synchronization Manually

You can, at any time, perform an incremental Always-On Monitoring synchronization by running the sync command.

% $AOM_HOME/scripts/emsctl sync

When performing a manual incremental synchronization, you do not need to shut down Always-On Monitoring: You can run the SYNC command regardless of whether Always-On Monitoring is up or down.

Note:

  • An incremental synchronization is automatically performed whenever you run the enable_notification command. You can bypass the synchronization by specifying the -nosync option.

  • AOM does not currently support the use of Microsoft Exchange Online with OAuth 2.0 for email notifications. If Enterprise Manager is configured to use Microsoft Exchange Online with OAuth 2.0, email notifications for AOM will not work. If you plan to use AOM, do not configure Microsoft Exchange Online with OAuth 2.0 in Enterprise Manager until this feature is supported in a future Enterprise Manager release.
