ogg由普通模式转换成集成捕捉模式实验

转换条件查看上篇：将ogg捕捉模式由普通模式转换成集成捕捉

客户有一个数据库需要将源端抽取由普通模式转换成集成模式，详细诊断转换成集成模式的原因查看：ogg-00723 ogg-00715

具体步骤：

打开虚拟机

GGSCI (og1) > info all

EXTRACT     ABENDED     EXTTS       00:00:00      2234:51:05  

发现进程都abended，数据库未配置开机自启动

执行脚本，给ogg用户授权（我的ogg用户是ogg_ts）

查询视图

抽取正常，投递都abended，因为目标端未开启。

此时，如果观察本地的trail文件发现自动增长一个文件号

总结：

三个步骤：

1.运行授权脚本

 exec dbms_goldengate_auth.grant_admin_privilege('OGG_TS');

2.注册数据库

register extract extts database

3.升级为集成模式

alter extract extts ，upgrade integrated tranlog
