Remote Job Entry
Encyclopedia
Remote job entry is the term used to describe the process of sending jobs to Mainframe computer
s from remote workstations, and by extension the process of receiving output from mainframe jobs at a remote workstation.
The RJE workstation is called a remote because it usually is located some distance from the host computer. The workstation connects to the host through a modem
or local area network
(LAN).
The terms Remote Batch, Remote Job System, and Remote Job Processing are also used for RJE facilities.
