UseGoldengateInitialDataLoad - 数据库编程

我们在搭建ogg的时候，通常需要先对目标库进行初始化，那么初始化的方式很多。现在介绍ogg自己的初始化方式。

测试环境：
Souce DB:
OS：redhat 6.3
Name:zbdba1
DB:11.2.0.4
OGG:11.2.1.0.1


Target DB:
OS：redhat 6.3
Name:zbdba2
DB:11.2.0.4
OGG:11.2.1.0.1

这里着重介绍 Initial Load，具体安装配置请参考：

Source and target DB：
配置并开启manager进程：

GGSCI (zbdba1) 1> view param mgr
