可以知道目标端RADAR.PK_ON_BUSIN_CHANCE表上的BC_ID = 441933626字段重复


处理办法


1.跳过当前事务
2.尝试加入 handlecollisions 参数解决该问题
3.尝试手动修复 target 上的数据
4.尝试加入REPERROR  参数 ignore这个错误


1.跳过当前事务

当然如果还有失败的事务还可以继续next用上面的方法，不过如果有几个连续的事务需要skip，那就可以用另外一个方法
start XXX skiptransaction


2.尝试加入 handlecollisions 参数解决该问题
1）源端删除了目标端没有的记录可以使用
start XXX skiptransaction 
2）target丢失update记录(missing update)，更新的键值是非主键=》 忽略该问题并不记录到discardfile
target丢失update记录(missing update)，更新的键值是主键 
加入HANDLECOLLISIONS后，rep可以继续工作且不生成discard记录
丢失update的更新操作是针对主键的更新，此时replicat会尝试插入一条记录而非忽略该update。注意插入的记录可能不是完整的行，若要求完整的行记录则要求EXTRACT使用PKUPDATE选项。需要加入的选项是FETCHOPTIONS FETCHPKUPDATECOLS，将以上选项加入到EXTRACT参数文件中，并重启EXTRACT。 这将引起extract捕获完整的主键更新镜像。
3）重复插入已存在的主键值到target表中，这将被replicat转换为UPDATE现有主键值的行的其他非主键列：
处理完之后一定要取消HANDLECOLLISIONS参数
可以通过send 命令动态取消HANDLECOLLISIONS
send XXX, NOHANDLECOLLISIONS




4.尝试加入REPERROR  参数 ignore这个错误
可以忽略掉重复数据的插入而其他类型的报错则abend
REPERROR (DEFAULT, ABEND)
REPERROR (-1, IGNORE)


如当DDL复制报ORA-1430错误，传递了重复的alter语句导致，则可以用ddlerror （1430, discard）将错误信息扔到discard文件里。
