Noflush

    Indicates whether forced writes of audit journal records are
    currently enabled for the database. Forced writes will cause
    Oracle Rdb to write (flush) the audit journal record immediately
    out to disk when the audit record is produced, rather than
    waiting for the audit server to flush the audit records at
    specified intervals of seconds.

    The default is the Noflush qualifier, which flushes audit records
    every interval of seconds. To specify the interval, use the DCL
    command SET AUDIT/INTERVAL=JOURNAL_FLUSH=time.
