Should the OEM Console be displayed at all times (when there are scheduled jobs)?

When a job is submitted the agent will confirm the status of the job. When the
status shows up as scheduled, you can close down the OEM console. The
processing of the job is managed by the OIA (Oracle Intelligent Agent). The OIA
maintains a .jou file in the agent's subdirectory. When the console is launched
communication with the Agent is established and the contents of the .jou file
(binary) are reported to the console job subsystem.

Note that OEM will not be able to send e-mail and paging notifications when the
Console is not started.
