/SCRATCH_DISK=device-spec

    CRDB uses one or two temporary scratch files to build the
    database if /FAST_LOAD is used (the default). The /SCRATCH_DISK
    qualifier can be used to specify the device on which these files
    are created. It may be useful to place these files in a specific
    place, either to improve performance or to get around protection
    and quota limitations.

    If /SCRATCH_DISK is not specified, the temporary files will be
    created on the disk specified by PMDF_SCRATCH. If PMDF_SCRATCH
    is not defined, the temporary files will be created on the disk
    specified by SYS$SCRATCH. If SYS$SCRATCH is not defined, the
    temporary files will be created on whatever disk the current
    default directory is on.
