The job entry subsystem of OS/VS1

摘要

In this paper, the facilities of the job entry subsystem of OS/VS1 have been described briefly. The comparison between OS/MFT job management and oslvsl job management identified several areas where performance could be improved and described the approaches taken by JES1 for such improvement. The input to the subsystem, primarily through system generation parameters, was considered. Compatibility with OS/MFT and the flexibility provided by the JESl reconfiguration facility were teh main points of this discussion. In a brief analysis of the JES1 to perform efficiently in a virtual storage environment were illustrated. Thus, it was shown how JES1 extended OS/MFT job management by providing additional functions and improving performance in the virtual storage environment.
