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 /*+ rule */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;
