OGG有传统的经典架构，也有最新的微服务，2个都可以远程捕获和应用数据，对数据库服务器是0侵入，而传统的经典架构是纯命令行模式，最新的微服务架构是图形化界面操作，几乎所有操作都可以在界面进行。相关文章可以参考：

生成MySQL端DDL语句
可以使用Navicat的数据传输功能或其它工具直接从Oracle端生成MySQL类型的建表语句如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | mysql -uroot -plhr -h 172.72.7.35 -D lhrdb -f < ddl.sql mysql> show tables; +----------------------+ | Tables_in_lhrdb | +----------------------+ | ADDRESSES | | CARD_DETAILS | | CUSTOMERS | | IMAGE_LOB | | INVENTORIES | | LOGON | | ORDERENTRY_METADATA | | ORDERS | | ORDER_ITEMS | | PRODUCT_DESCRIPTIONS | | PRODUCT_INFORMATION | | TCUSTMER | | TCUSTORD | | TSRSLOB | | TTRGVAR | | WAREHOUSES | +----------------------+ 16 rows in set (0.01 sec) |
DDL语句如下：

Oracle全量同步到MySQL
注意：在此阶段，源端需要停业务，不能产生新数据。

可以发现“Record”记录在变化，同时查询MySQL端的表数据量，会发现行数在不断增大：

大概7分钟之后，同步完成，查看日志：
