--失数据
办法1.v$archived_log查询到下个日志的时间点，重新指定抽取进程的时间点,启动抽取进程

select a.NAME,
a.FIRST_TIME,
a.NEXT_TIME,
a.COMPLETION_TIME,
a.SEQUENCE#,
thread#,
resetlogs_id,
archived
from v$archived_log a
where a.NAME is not null
order by a.FIRST_TIME desc

alter extract EXT_JS ,begin 2020-04-26 15:06:57

办法2.实在不行就从现在启动。
alter extract EXT_JS begin now

--不丢失数据
办法3.重新初始化数据后，启动。
