.1             开启归档模式
GoldenGate是基于oracle日志变化的捕获，所以为了完整的捕获到oracle数据库的变化，有必要将归档模式开启。

  SQL>  alter system set log_archive_dest_1='location=D:\app\arch' scope=both;
  SQL>  shutdown immediate
  SQL>  startup mount
  SQL>  alter database archivelog;
  SQL>  alter database open;
  SQL>  archive log list

注意，由于上面命令涉及停止数据库应用，应结合业务实际情况进行操作。

4.1.2             开启附加日志
在oracle中我们可以通过rowid来定位某条记录，但是目标端的数据库和源端数据库的数据库可能完全不一样，所以无法通过rowid来确定源端数据库的逻辑变化，这时附件日志supplemental log便登上了表演的舞台。数据库在开启附加日志功能后，对于源端的修改操作，oracle会同时追加能够唯一标示记录的列到redo log。这样目标端数据库就可以知道源端发生了哪些具体的变化。
   SQL>       alter database add supplemental log data;
   SQL>       alter system switch logfile;
   SQL>       select supplemental_log_data_min from v$database;

4.1.3             开启强制日志模式
SQL>alter database force logging;
SQL>SELECT FORCE_LOGGING FROM V$DATABASE;

alter system set enable_goldengate_replication=true;

4.1.4             goldengate创建用户并授权

源端oracle数据库创建账号：

create tablespace ggstab datafile 'D:\app\oradata\fdcp\ggstab01.dbf' size 1024M autoextend on ;
create user ggs identified by ggs default tablespace ggstab temporary tablespace temp;
grant dba to ggs;
