ogg修改extract进程从当前抽取

Posted 2020-06-14 丹心明月

因为是测试环境，几个月之前创建的ogg再次打开，源端目标端表结构已经面目全非，然后就新建了一个表，重新开始同步，但是抽取进程不是现在：
GGSCI (single1) 12> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
EXTRACT     RUNNING     DPEND       00:00:00      00:00:03   
EXTRACT     ABENDED     EXTND       00:00:00      1688:11:20

如何从现在开始抽取呢？在咨询了专家以后，得到如下命令：

GGSCI (single1) 13> alter extract extnd begin now
EXTRACT altered.

再次查看进程状态：
GGSCI (single1) 10> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
EXTRACT     RUNNING     DPEND       00:00:00      00:00:00   
EXTRACT     RUNNING     EXTND       00:00:00      00:00:09

OK，又可以继续用了。 

PS:正式环境慎用！
