SELECT NVL(MAX(FIRST_CHANGE#),0)

RESETLOGS_CHANGE# NEXT_RESETLOGS_CHANGE# FROM V$DATABASE_INCARNATION START
WITH RESETLOGS_CHANGE# = :B2 AND RESETLOGS_TIME = :B1 CONNECT BY PRIOR
PRIOR_INCARNATION# = INCARNATION#) D2 WHERE ((:B5 = :B4 AND
AL.RESETLOGS_CHANGE# = D2.RESETLOGS_CHANGE# AND AL.RESETLOGS_TIME =
D2.RESETLOGS_TIME AND AL.FIRST_CHANGE# >= D2.RESETLOGS_CHANGE# AND
AL.FIRST_CHANGE# < D2.NEXT_RESETLOGS_CHANGE#) OR (AL.RESETLOGS_CHANGE# =
:B2 AND AL.RESETLOGS_TIME = :B1 )) AND AL.FIRST_TIME <= :B3
原因:
bug6051693慢速同步并显示所有正在约2分钟
使用闪回数据库保证恢复点使用同一问题的SQL时,bug5620640长时间等待打开 DB RESETLOGS
