Goal

What is Out of Band Email Notification?

Out of Band email notification is a mechanism that is used to send an email notification when the "OMS and Repository database" target (oracle_emrep) is down, in order to alert the EM Administrator that the OMS is not available. Normally the OMS is responsible for sending all metric alert notifications, but in cases where the OMS or repository database is down, it is not able to do this. Therefore the Out of Band email notification is a backup mechanism for sending email notification in cases where the OMS or repository database itself is down.  When an out of band email notification is sent, the email notification will be generated by the agent which monitors the OMS and Repository target (oracle_emrep) target. Therefore this method is only applicable to the agent which is installed on the same machine as the OMS (also known as the chained agent). In the case of a multi-OMS setup, the Agent on the primary OMS node is responsible for monitoring the oracle_emrep target.

This article explains how to configure email notification from EM 12c for the times when the EM 12c Cloud Control repository database is not functioning.
