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：

创建检查点表
添加trandata
添加脉动表
配置ora19c到ora21c的实时同步
创建extract进程
1 2 3 4 5 6 7 | extract ext19c USERIDALIAS ora19c, DOMAIN OGGMA DDL INCLUDE MAPPED DDLOPTIONS REPORT TRANLOGOPTIONS EXCLUDETAG 99 exttrail ./dirdat/e1 table lhr.*; |
创建replicate进程
1 2 3 4 5 6 | REPLICAT rep19c USERIDALIAS ora21c DOMAIN OGGMA DDL INCLUDE MAPPED DDLOPTIONS REPORT DBOPTIONS SETTAG 99 MAP lhr.*, TARGET lhr.*; |
测试同步
在Oracle 19c端建表和插入数据：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | create table t1 (id number primary key,name varchar2(255)); insert into t1 select object_id,object_name from dba_objects where object_id<=20; commit; select count(8) from t1; LHR@lhrsdb> create table t1 (id number primary key,name varchar2(255)); Table created. LHR@lhrsdb> insert into t1 select object_id,object_name from dba_objects where object_id<=20; 19 rows created. LHR@lhrsdb> commit; Commit complete. LHR@lhrsdb> select count(8) from t1; COUNT(8) ---------- 19 |
从源端查看：
查看目标端：
1 2 3 4 5 | LHR@127.0.0.1/pdb2> select count(8) from t1; COUNT(8) ---------- 19 |
可见，DDL和DML同步都已经完成！
配置ora21c到ora19c的实时同步
创建extract进程
1 2 3 4 5 6 7 | extract ext21 USERIDALIAS ora21c, DOMAIN OGGMA DDL INCLUDE MAPPED DDLOPTIONS REPORT TRANLOGOPTIONS EXCLUDETAG 99 exttrail ./dirdat/e2 table lhr.*; |
创建replicate进程
1 2 3 4 5 6 | REPLICAT rep21 USERIDALIAS ora19c DOMAIN OGGMA DDL INCLUDE MAPPED DDLOPTIONS REPORT DBOPTIONS SETTAG 99 MAP lhr.*, TARGET lhr.*; |
测试同步
在Oracle 21c操作：
1 2 3 4 | create table t2 (id number primary key,name varchar2(255)); insert into t2 select object_id,object_name from dba_objects where object_id<=20; commit; select count(8) from t2; |
可见，DDL和DML同步都已经完成！
配置完成后的效果
简单测试以下DDL语句类型：
1 2 3 4 5 | create table drop table CREATE INDEX CTAS truncate |
都没有问题，其它类型没有测试！

压测同步并查看检测数据
ora19c造数据：

能不能出个传统安装方式的教程
参考：https://www.xmmup.com/dbbao63xiangmufenxiangshiyongora2pgqianyioracle19cdaopg13bingshiyongoggpeizhishi.html/3#421_yuan_duan_an_zhuangOGG_ruan_jian
这个教程感觉源端跟目标端是分开的，如果像本文那样的架构，独立部署，实现远程抽取和投递，传统方式怎么安装，并且源和目标端的数据库版本还不一样
一样的
