Historically, Oracle's import and export capabilities have used disk files as storage intermediaries for unloading and reloading databases. The way to "swap files" for larger databases is a big problem. Because a large file will exceed the operating system's limit on file size, the export cannot be implemented. Some innovative data administrators use file compression, such as the compression feature in Unix, to obtain the maximum size of a swap file. The import and export features in later vers
