环境

ogg12c 版本。

源端目标端都在 a 列上有主键。

 

准备工作

停掉抽取进程和投递进程

源端插入几条数据

源端抽取进程跳过这些 insert ， alter extract EXT_MI01,begin now

启动抽取进程和投递进程

再次加入 handlecollisions 参数，目标端数据被修改为与源端一致。

 

 

总结：

1.handlecollisions 是复制进程参数

2. 对于 delete 操作，无 handlecollisions 参数，源端 delete 一条数据，目标端没有符合要求，那么复制进程会 abend ；

有 handlecollisions 参数，复制进程不会 abend ，目标端会跳过 delete

3. 对于 update 操作，无 handlecollisions 参数，源端 update 一条数据，目标端没有符合要求，那么复制进程会 abend ；

有 handlecollisions 参数，复制进程不会 abend ，目标端将 update 变为 insert ，将数据插入目标端。

4. 对于 insert 操作，无 handlecollisions 参数，源端 insert 一条数据，目标端违反了唯一性约束，那么复制进程会 abend ；

有 handlecollisions 参数，复制进程不会 abend ，目标端将按照源端数据，修改目标端违反唯一性约束的数据。
