    • Options Library

    • View Profile Library

    • Variable Definition Library

    • Log Data Set

    • History File Data Set

    • Report Output Data Set

    • UPF Data Set

    Note

    The IMS control region must have UPDATE authority for the Log and History File data sets.

    During IMS control region initialization, the IMS DB/DC SYSGEN linkedit dates are written to the Log and History File control record (if required). The Log and History File SYSGEN dates are also updated following an online change MODBLKS GEN implementation.

    The following fields are possible for these panels:

    data_set_type

    The type of data set that you are allocating. This is not an editable field.

    SMS Management class

    The SMS management class to be used for the data set allocation. This field is not required unless your installation requires the use of SMS.

    The SMS storage class to be used for the data set allocation. This field is not required unless your installation requires the use of SMS.

    Volume serial

    The DASD volume serial (VOLSER) where the data set will be allocated.

    Generic unit

    The generic unit name to be used for the data set allocation. Generic names (also referred to as esoteric) are given to groups, or pools, of DASD volumes. Some common generic/esoteric names are SYSDA, SYSALLDA, and SCRATCH.

    Space units

    The space unit type to be used for the data set allocation. Valid values are TRKS or CYLS.

    Primary quantity

    The number of primary space units to be used for the data set allocation. You previously specified the space unit type on this panel.

    Secondary quantity

    The number of secondary space units to be used for the data set allocation. You previously specified the space unit type on this panel.

    Directory blocks

    The number of directory blocks to be provided for a partitioned data set. Specify zero for a sequential data set.
