VSAM, for all its complex capabilities, seems to operate 'simply' at a very basic level of the OS. Think of SMF running very early in IPL. ICF catalogs are VSAM. I'm not sure it was always thus, but it seems now to have little trouble functioning within a minute or two of IPL LOAD. As Walt Farrell said, even if RACF could be rewritten for VSAM, what's the ROI?

ACF2 is supposed to start before JES2/JES3. It is configured as a subsystem and its PARM field includes the name of the job entry subsystem to start (i.e. ACF2 starts JES). -- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* [email protected] (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
