As indicated in the Appendix C of the ICKDSF Guide, these are theoretical maximums. The same could be done for VSM/SMS managed datasets.
i.e. If *EVERY* dataset on the volume was a 1-track VSAM DS (or SMS managed DS), what is the size if the VVDS required for the larger of the two possibilities? <snip> Since the VVDS is a catalog extension supporting both VSAM and SMS, wouldn't the size of the VVDS depend on mix of VSAM and non-VSAM datasets and possibly even the type of VSAM datasets on the volume? :>: -----Original Message----- :>: From: IBM Mainframe Discussion List [mailto:[email protected]] On :>: Behalf Of Staller, Allan :>: Sent: Friday, February 07, 2014 5:53 AM :>: To: [email protected] :>: Subject: Re: Implicit VVDS creation :>: :>: As I commented recently in another thread, in the ICKDSF manual there is :>: a table of MAXVTOC/MAXVTOCIX sizes in : :>: "Calculating the size of the VTOC index" in appendix C of ICKDSF Users :>: Guide GC35-0033-39. :>: :>: Unfortunately, there is no reference to the size of the VVDS required to :>: support a MAXVTOC/MAXVTOCIX formatted volume. :>: Would be nice to have! </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
