在dg库上搭建ogg
备注: Oracle DG (主->备库1->备库2) 级联方式
网站题目:在dg库上搭建ogg
浏览路径:http://scyanting.com/article/piesso.html
主库: 10.118.242.216 sid_name=sfpay2
备库1: 10.118.242.215 sid_name=sfpay2 => ogg 主库
ogg库1: 10.118.230.27 sid_name=sfpay3 => ogg备库1
ogg库2: 10.118.242.214 sid_name=sfpay1 => ogg备库2
ogg 方式: 一个捕获进程,多个pump 进程(一对多方式)
ogg 一库多实例时,请配置好 setenv 参数(oracle_sid,nls_lang, oracle_home), 记住 tnsname.ora 对应好.
注意ogg source 端,target 端 时区。
ogg extract 端 不需要 做checkpoint ,以及备库只能做 DML ogg 同步,DDL 不支持。

测试结果:
source 端(DG备库1) 的所有数据初始话,都以 DG主库 为准(scn, 数据的导出)
source 端(DG备库1) 的ogg 操作,都需要在 DG 主库上执行ogg脚本,trandata log. 参数可以忽略。
1: 主库 执行ogg 脚本
2: 因standby database 不支持 ogg 的DDL 方式,注销掉所有ddl 方式。
3: ogg source端,dg 备库1 在info trandata schema.* 时,可能为disabled 状态,但是DG主库enable 即可。

pump01 同样,略过。
6, 数据初始化 expdp 通过flshback_scn , DG主库。
7, target 端启动:

9, 完成。
