自己今天一個解決過程，希望能給大家一點啟發(fā)

錯誤原因：
因兩邊同步出錯，數(shù)據(jù)已不一致，我添加字段后也沒有有同步過去，所以我把表刪除重建。
但后來錯誤更多，想直接刪除同步文件（./dirdat/gg000000）看看。但目標(biāo)端一直要求此文件。
后來
重置Extract 和Replicat 進(jìn)程的Trail 序列號

?? ?alter extract ext1,extseqno 0,extrba 0

?????? alter replicat rep1,extseqno 0,extrba 0

目標(biāo)端問題解決，但源端問題仍舊，搞了半天，沒解決，只好重新配置EXTRACT了。
這操作的感慨是：OGG還是有很多運(yùn)維的工作可做，如果老師能講解得更詳細(xì)一些就好。


操作如下：

GGSCI (gg1) 78> alter extract ext1,begin now

EXTRACT altered.

GGSCI (gg1) 79> alter extract ext1,extseqno 0,extrba 0

EXTRACT altered.
