Oracle : Ошибка ORA-19905

"log_archive_format must contain %%s, %%t and %%r"
*Cause: log_archive_format is missing a mandatory format element.
Starting with Oracle 10i, archived log file names must contain each
of the elements %s(sequence), %t(thread), and %r(RESETLOGS ID) to
ensure that all archived log file names are unique.
*Action: Add the missing format elements to log_archive_format.
