由于系统重启，，重启之后操作人员并未重启goldengate进程，导致复制链路断掉。
而且由于时间过去较长，相关的部分归档日志已经备份删除。首先试了一下重新抽取进程，发现缺少归档文件。
尝试追归档，不幸的是正巧备份软件出问题，无法正常重启链路了。

只能进行重新初始化操作，首先确认抽取进程ext1，传输进程dpump1,复制进程rep1都处在stop状态
修改e进程启动时间
ALTER EXTRACT ext1, TRANLOG, BEGIN 2015-04-07 17:00

启动e进程，d进程
start ext1
start dpump1

根据scn号重新初始化数据
SELECT dbms_flashback.get_system_change_number from dual;
--10653006236238
可以用dblink或者数据泵的方式进行。

重新启动r进程，根据scn号

START REPLICAT rep1, aftercsn 10653006236238

查看相关进程状态，链路状态正常
