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。
