One or more input after-image journal backup files to be used
    as the source of the extraction operation. Multiple journal
    files can be extracted by specifying a comma-separated list
    of file specifications. Oracle RMU supports OpenVMS wildcard
    specifications (using the * and % characters) to extract a
    group of files. A file specification beginning with the at
    (@) character refers to an options file containing a list of
    after-image journal files (rather than the file specification
    of an after-image journal itself). If you use the at character
    syntax, you must enclose the at character and the file name in
    double quotation marks (for example, specify aij-file-name as
    "@files.opt"). The default file extension is .aij.
