    Our intention has been to offer an appreciation of VSAM performance sensitivities and to relate those sensitivities to data set design parameters. This has been done in the hope that designers may become more aware of the effects of their choices among those parameters. This discussion has been restricted to VSAM as it applies to IBM operating systems. Effects of paging, the VSAM catalogue, and VS... View full abstract»

    One of the major concerns of users of virtual storage systems has also been a major objective of system designers, that is, ease of moving programs for OS/MFT systems to OS/VS1 systems. Discussed in this article have been supervisor and job scheduling operations that make such a move possible, whereby programs remain wholly or largely intact. The major innovation of virtual storage systems is that... View full abstract»

    In conclusion, three areas of concern that continue to be brought up repeatedly with respect to system integrity support are now addressed. These questions concern thiem pact of integrity support on the system as a whole, the feasibility of integrity on other systems, and the questionos f what level of integrity has been achieved in vs2 Release 2 and what in fact constitutes an adequate level of s...

    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 w... View full abstract»
