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.
