Definition of "Remote Job Entry" |
Remote job entry is the procedure for sending requests for data processing tasks or 'jobs' to mainframe computers from remote workstations, and by extension the process of receiving the output from such tasks at a remote workstation. / Remote Job Entry (RJE) is a facility that allows remote computer users to submit a batch job (the running of a specific program or group of programs) to a centrally-located computer (typically a mainframe). Widely used for decades in large business enterprises, RJE was first developed in the 1960s as part of IBM's System/360 mainframes. An RJE protocol was defined for use on the early Internet in 1972. Originally, jobs were submitted to mainframe computers manually on punch cards and initiated by a mainframe operator. When remote typewriter and later display terminals (later called workstations) became available, a program was needed that would allow programs and jobs to be sent to the mainframe electronically. Today, RJE allows for the transfer of jobs and files back and forth among multiple workstations and mainframes. / A tape relay is a method of retransmitting teletypewriter traffic from one channel to another, in which messages arriving on an incoming channel are recorded in the form of perforated tape, this punched tape then being either fed directly and automatically into an outgoing channel, or manually . |
