Designates a file specification for the target database, which
    is an Oracle Rdb database. Replication Option uses the file
    specification to create and access the target database. You can
    use either a full or partial file specification or a logical
    name. The file-spec parameter is required. If you do not specify
    the node, device, or directory, Replication Option assumes the
    SYS$LOGIN of the user defining the transfer. If the file type
    is not .RDB, the transfer will fail during the creation of the
    target database. The default file type is .RDB.

    When you specify the name of a remote node as part of the file
    specification, you can include an access control list (ACL) for
    login. However, the most effective method of allowing access to a
    target node uses proxy accounts.

    If you use DECnet/OSI note that Replication Option expects node
    names in file specifications to be from one to six characters
    long. DECnet/OSI permits node names to be much longer than this.
    In order to use Replication Option in a DECnet/OSI environment,
    you must define and use short synonyms for the long node names.
    Node name synonyms can be registered either in a local or
    distributed name service database. For details on establishing
    node name synonyms, refer to the documentation for DECnet/OSI.

    Note that the file specification is resolved at run time. All
    logical names used for the file-spec parameter are resolved
    within the copy process after it executes the transfer definer's
    login initialization file, LOGIN.COM. If the target database
    name is a logical symbol name, when it is translated, the default
    directory is the one pointed to by SYS$LOGIN.

    Replication Option makes no attempt to verify whether a
    database or file of the same name already exists in the target
    directory. When you issue a duplicate file specification,
    Replication Option creates a second file with the same name, but a
    higher version number.

    If the database system (Oracle Rdb) returns an error while
    attempting to create a database in the target directory, the
    copy process writes the error in the copy process log file and
    returns the error status to the transfer monitor.
