Oracle : Ошибка ORA-01266


"Unable to create unique file name"
*Cause: Unable to create a unique file name for an Oracle managed file.
Oracle tried several names but each file name was already in use
in the default destination directory for the file type.
*Action: Retry the operation. If that fails, also, it may be
necessary to change the default destination directory for
the file type and then retry.
