SMS

  • DATACLAS
    A named collection of data set and space attributes (for Systems Managed data sets)

  • STORCLAS
    A named collection of performance and device availability attributes (for Systems Managed data sets)

  • MGMTCLAS
    A named collection of migration, backup, and expiration attributes (for Systems Managed data sets)

Allocation

  • Unit
    Allocation unit for the data set. Possible values are:

    • BLK - Space is allocated in blocks

    • CYL - Space is allocated in cylinders

    • TRK - Space is allocated in tracks

  • Primary
    Initial allocation of cylinders, tracks, or blocks for a data set on direct access. Depending on the allocation unit, the content of this field is:

    • For CYL, the number of cylinders allocated

    • For TRK, the number of tracks allocated

    • For BLK, the number of blocks allocated

  • Secondary
    The number of secondary tracks, cylinders, or blocks allocated. Depending on the allocation unit, the content of this field is:

    • o For CYL, the number of secondary cylinders allocated

    • o For TRK, the number of secondary tracks allocated

    • o For BLK, the number of secondary blocks allocated

  • Volume
    CountThe total number of volumes the data set occupies (1 to 56) Curr Extent Number of current physical Count extents for the data set

Format

  • DS Org
    Physical organization of the data stored in this data set

  • Rec Fm
    Denotes how the logical records are related to the physical way the data is stored in the data set. Possible values are:

    • F - Fixed length blocks

    • FB - Fixed blocked records

    • U - Undefined or user-defined blocking

    • VB - Variable blocked

    • VBS - Variable blocked spanned

  • Log Rec Len
    Specified length of the records that reside in this data set

  • Blk Size
    Specified block size for the data in this data set

  • Buffer Count
    Number of buffers for non-VSAM data sets.

  • Buf Size
    For non-VSAM data sets, the size of the data buffers for this data set

  • Stripes
    For extended sequential data sets, the number of stripes used to read/write the data

  • Concat #
    The concatenation number of this data set in the DDname. If there are no concatenations, or if the data set is the first data set in the DDname, the value is zero Concat #The concatenation number of this data set in the DDname. If there are no concatenations, or if the data set is the first data set in the DDname, the value is zero (0). The total number of data sets is the Concat # + 1
