Message Oracle IMP-00056 - multiple devices specified for tape input

ERRORmultiple devices specified for tape input
CAUSEYou specified multiple file names when doing an import from a tape device. Import uses the same device for reading all tapes, regardless of the number of tape volumes required. For this reason, export will accept only one value for the FILE parameter when writing to tape.
ACTIONReenter the IMPORT command, but specify only one tape device in the FILE parameter.
