大批量执行DML语句造成回滚段大量占用,又回退操作,如何直观查询数据回滚情况?

单机环境 查询回滚执行进度

select s.sid, r.name rr, nvl(s.username,'no transaction') us, s.osuser os, s.terminal te, t.used_urec rec, t.used_ublk blk from v$lock l, v$session s, v$rollname r,v$transaction t where l.sid = s.sid(+) and trunc(l.id1/65536) = r.usn and l.type = 'TX' and t.ses_addr = s.saddr and l.lmode = 6;
