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, po, ps, 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.

      • po (dict) –

        The details of a PO type data set.

        • encoding (string) –

          The character set encoding of the data set.

        • format (string) –

          The format of the data set records.

      • ps (dict) –

        The details of a PS type data set.

        • encoding (string) –

          The character set encoding of the data set.

        • format (string) –

          The format of the data set records.

      • 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.

    • fileSize (integer) –

      File size of the dataset.

    • 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.
