Job Entry Subsystem 1 (JES1)


Job Entry Subsystem 1 was released by IBM as an integral part of OS/VS1 as an enhancement to the basic functions that users of VS1's predecessor, MFT, had.

History

IBM proclaimed JES1 to be "the single most important addition" to the job scheduling provided by VS1. IBM Systems Journal defined JES1's services as Spooling and scheduling, adding "Its three major components are peripheral services, central services, and queue management."
JES1 was not popular, because HASP and ASP users often had made local modifications, and wanted to retain their investment.

Features

JES1 permitted batch jobs to be submitted from remote sites, executed on an IBM mainframe, then produce printed and punched output either at the originating site or, if desired, at the main site or another remote site. The Remote Entry Services of OS/VS1 is similar to Remote Job Entry on OS/360 but the protocol for programmable workstations is that used by HASP II and ASP rather than that used by RJE.
