mysql>

show global variables like '%binlog_format%';--查看MYSQL的binlog格式

这个错误是由于MYSQL的binlog格式没有设置成ROW模式，如果使用OGG做数据初始化(数据迁移，不需要后续的同步操作)，对binlog没有特殊的要求，使用默认的MIXED模式就可以，如果需要同步数据变化，就必须使用ROW模式。

解决方法：在my.cnf配置文件中，将binlog_format设置的值改成ROW，如果配置文件中没有这个设置，那么添加binlog_format=ROW即可

三种binlog格式：

Row：日志中会记录成每一行数据被修改的形式，然后在slave端再对相同的数据进行修改。

Statement：每一条会修改数据的sql都会记录到 master的bin-log中。slave在复制的时候sql进程会解析成和原来master端执行过的相同的sql来再次执行。

MIXED：智能混合 STATEMENT 和 ROW

ODS报错：

2022-04-15 22:21:24 ERROR OGG-01668 PROCESS ABENDING.

原因：repsm配置中，源端表未加用户名
