Response Structure

• (dict) --

  • blocksize (integer) --

    The size of the block on disk.

  • creationTime (datetime) --

    The timestamp when the data set was created.

  • dataSetName (string) --

    The name of the data set.

  • dataSetOrg (dict) --

    The type of data set. The only supported value is VSAM.

    Note

    This is a Tagged Union structure. Only one of the following top level keys will be set: gdg, vsam. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

    'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}
    

    • gdg (dict) --

      The generation data group of the data set.

      • limit (integer) --

        The maximum number of generation data sets, up to 255, in a GDG.

      • rollDisposition (string) --

        The disposition of the data set in the catalog.

    • vsam (dict) --

      The details of a VSAM data set.

      • alternateKeys (list) --

        The alternate key definitions, if any. A legacy dataset might not have any alternate key defined, but if those alternate keys definitions exist, provide them as some applications will make use of them.

        • (dict) --

          Defines an alternate key. This value is optional. A legacy data set might not have any alternate key defined but if those alternate keys definitions exist, provide them, as some applications will make use of them.

          • allowDuplicates (boolean) --

            Indicates whether the alternate key values are supposed to be unique for the given data set.

          • length (integer) --

            A strictly positive integer value representing the length of the alternate key.

          • name (string) --

            The name of the alternate key.

          • offset (integer) --

            A positive integer value representing the offset to mark the start of the alternate key part in the record byte array.

      • cacheAtStartup (boolean) --

        If set to True, enforces loading the data set into cache before it’s used by the application.

      • compressed (boolean) --

        Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.

      • encoding (string) --

        The character set used by the data set. Can be ASCII, EBCDIC, or unknown.

      • primaryKey (dict) --

        The primary key of the data set.

        • length (integer) --

          A strictly positive integer value representing the length of the primary key.

        • name (string) --

          A name for the Primary Key.

        • offset (integer) --

          A positive integer value representing the offset to mark the start of the primary key in the record byte array.

      • recordFormat (string) --

        The record format of the data set.

  • lastReferencedTime (datetime) --

    The last time the data set was referenced.

  • lastUpdatedTime (datetime) --

    The last time the data set was updated.

  • location (string) --

    The location where the data set is stored.

  • recordLength (integer) --

    The length of records in the data set.
