版本：11gr2 环境：linux
实施dg的方法有很多种，这里介绍使用oracle提供的deplicate复制功能建立异机的dg的方法。对于备库安装和主库一样路径的软件和数据存放结构。配置参数文件，监听文件，启动到nomount状态后，就可以在主库上使用rman进行建立dg！
一前期准备工作
---对于主库：
1 开启归档功能
shutdown normal
shutdown immediate
startup mount
alter database archivelog;
alter database open;
--设置归档路径
alter system set log_archive_format = "archive_%t_%s_%r.log" scope=spfile;
alter system set log_archive_dest_1='LOCATION=/home/opt/oracle/archive_log';
alter database force logging;
2 拷贝源库的密码文件到备库主机和主机的一样的路径。
3 修改spfile参数文件。
db_name=yangql
alter system set db_unique_name=yangql scope=spfile;
alter system set log_archive_config='dg_config=(yangql,yangqldg)' scope=both;
alter system set log_archive_dest_1='LOCATION=/home/opt/oracle/archive_log' scope=both;
alter system set log_archive_dest_2='SERVICE=yangqldg LGWR ASYN VALID_FOR=(ALL_LOGFILES,PRIMARY_ROLES) DB_UNIQUE_NAME=yangqldg' scope=both;
alter system set log_archive_dest_state_1=enable scope=both;
alter system set log_archive_dest_state_2=enable scope=both;
alter system set remote_login_passwordfile=exclusive scope=spfile;
alter system set log_archive_format=%t_%s_%r.arc scope=spfile;
alter system set log_archive_max_processes=30 scope=spfile;
alter system set FAL_SERVER=yangqldg scope=both;
alter system set FAL_CLIENT=yangql scope=both;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT =AUTO SCOPE=both;
4 修改listener.ora tnames.ora文件
---listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pre_publish)(PORT = 1521))
)
)
SID_LIST_LISTENER =

)
----tnsnames.ora-----
yangql =

yangqldg =

)
(CONNECT_DATA =

)
)
----备库操作
---备库的参数文件yangqldg.ora中关于dg的部分内容----
db_name=yangql
db_unique_name=yangqldg

log_archive_dest_1='LOCATION=/home/opt/oracle/archive_log'

log_archive_dest_state_1=enable
log_archive_dest_state_2=enable/defer

log_archive_format=%t_%s_%r.arc

FAL_SERVER=yangqldg
FAL_CLIENT=yangql
-----listener.ora

(SID_DESC =
(GLOBAL_DBNAME = yangql)
(ORACLE_HOME = /home/opt/oracle/products/11.2.0)
(SID_NAME = yangql)
)
)
----tnsnames.ora-----
yangql =

)
yangqldg =
(DESCRIPTION =

)

)
)
--rman 复制
--启动备库到nomount状态
sqlplus "/as sysdba"
startup nomount pfile='/yangqldg.ora'
--执行duplicate standby 库
主库登陆rman，并auxiliary连接备库
