shutdown immediate
startup mount
alter database archivelog;
alter database open;

启用自动归档
Alter system set log_archive_start=true scope=spfile
参看参数
SQL> show parameter cluster_database
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
cluster_database                     boolean     TRUE
cluster_database_instances           integer     2
在一台主机上执行：
alter system set cluster_database=false scope=spfile sid='*';
在两台主机上执行：
shutdown immediate
在一台主机上执行：
startup mount（必需要等2台机器同时shutdown完毕即可）
alter database archivelog;
alter database open;
alter system set cluster_database=true scope=spfile sid='*';
shutdown immediate;
在两台主机上执行：
Startup
此时修改完毕即可启用归档，关闭归档方法类似。

-- source 、target 端执行
1.1    设置数据库为归档模式
数据库是否处于归档模式：
archive log list;
Select log_mode from v$database;
开启归档模式：
shutdown immediate;
startup mount;
alter database archivelog;
alter database open;
1.2    开启数据库附加日志
1)    检查附加日志情况
使用以下sql语句检查数据库附加日志的打开状况:
Select
SUPPLEMENTAL_LOG_DATA_MIN
,SUPPLEMENTAL_LOG_DATA_PK
,SUPPLEMENTAL_LOG_DATA_UI
,SUPPLEMENTAL_LOG_DATA_FK
,SUPPLEMENTAL_LOG_DATA_ALL from v$database;
2)    打开数据库附加日志
打开附加日志并切换日志（保证Online redo log和Archive log一致）
alter database add supplemental log data ;
alter database add supplemental log data (primary key, unique,foreign key) columns;
alter system switch logfile;
3)    确认附加日志情况
使用以下sql语句检查数据库附加日志的打开状况:
Select
SUPPLEMENTAL_LOG_DATA_MIN
,SUPPLEMENTAL_LOG_DATA_PK
,SUPPLEMENTAL_LOG_DATA_UI
,SUPPLEMENTAL_LOG_DATA_FK
,SUPPLEMENTAL_LOG_DATA_ALL from v$database;
注：确保最小附加日志,pk,uk,fk附加日志打开。而all columns的附加日志关闭；
如果all columns的附加日志打开的话，则需要使用以下语句予以关闭：
alter database drop supplemental log data (ALL) columns;
1.3    开启数据库强制日志模式
Alter database force logging;
注：该模式的打开需要和业务部门进行相关确认和讨论；如果数据库不能打开到force logging的模式下，则no logging的表无法进行同步；

1.4
alter system set enable_goldengate_replication=true;

1.5    创建运行GoldenGate的用户
1)    在源端采用ORACLE用户运行GoldenGate
2)    安装位置：/ogg
3)    创建GoldenGate数据库用户ggs
--create tablespace

create tablespace ggstab datafile '/oracle/app/oracle/oradata/oradb/goldengate02.dbf' size 1024M autoextend on;
create tablespace ggstab datafile '/home/oracle/app/oracle/oradata/oradb/goldengate02.dbf' size 1024M autoextend on;

-- Create the user
create user ggs identified by ggs default tablespace ggstab;

-- Grant role privileges
grant dba to ggs;

1.6    关闭数据库的recyclebin
查询当前recyclebin的参数值：
SQL> show parameter recyclebin

NAME                   TYPE      VALUE
------------------------------------ ----------- -------------------
recyclebin                string      OFF
SQL>
如不是off，需要关闭recyclebin：
SQL>alter system set recyclebin=off scope=both;

SQL>alter system set recyclebin=off deferred scope=both;


1.7    建立OGG的DDL对象
sqlplus "/ as sysdba"
SQL> @marker_setup.sql
Enter GoldenGate schema name:ggs

SQL> @ddl_setup.sql
Enter GoldenGate schema name:ggs

SQL> @role_setup.sql

Grant this role to each user assigned to the Extract, Replicat, GGSCI, and Manager processes, by using the following SQL command:

GRANT GGS_GGSUSER_ROLE TO

where is the user assigned to the GoldenGate processes.
注意这里的提示：需要手工将这个GGS_GGSUSER_ROLE指定给extract所使用的数据库用户（即参数文件里面通过userid指定的用户），可以到sqlplus下执行类似的sql:
GRANT GGS_GGSUSER_ROLE TO ggs;
注：这里的goldengate是extract使用的用户。如果你有多个extract，使用不同的数据库用户，则需要重述以上过程全部赋予GGS_GGSUSER_ROLE权限。
安装sequence复制对象：
SQL> @sequence.sql
1.8    安装提升性能工具
本步骤为可选步骤，一般情况下建议运行该步骤。
为了提供OGG的DDL复制的性能，可以将ddl_pin脚本加入到数据库启动的脚本后面，该脚本需要带一个OGG的DDL用户（即安装DDL对象的用户，本例中是ggs）的参数:
SQL> @ddl_pin ggs
