When we bring down OEM 12c application for maintenance for a period of time, lots of alert e-mails got sent out due to the fact the OMS is down. These alert e-mails contains the following info in the e-mail subject line:
EM Event: <Severity>:<target-name> - Agent is unable to communicate with the OMS. (REASON = Agent is Unreachable (REASON : Agent to OMS Communication is brokenFailure connecting to https://oem12-stg:4900/empbs/upload
These alert e-mails are not necessary and annoying. Does anyone know if there is a way to disable these alert e-mails temporarily during the OMS maintenance window?
