环境现状：

两台虚拟主机A和B：
1. A机器已安装ASM存储的Oracle 11g 实例
2. B机器已安装系统，配置以及目录结构均和A机器保持一致
     /u01 + 3块ASM盘
 
DG部署规划：

/u01/app/oracle/product/11.2.0/db_1
 

一、前期准备

1.1. A机器打包拷贝/u01/app到B机器（包含了grid和oracle软件安装目录）

# tar -zcvf app.tar.gz app

# scp app.tar.gz 192.168.99.160:/u01/

root@192.168.99.160's password:

app.tar.gz                                                                                                                           100% 3564MB  54.8MB/s   01:05

B机器解压，解压前确保第二步操作已完成。

# pwd

/u01

[root@JY-DBS u01]# ls

app.tar.gz  lost+found

[root@JY-DBS u01]# tar -zxvf app.tar.gz

解压完成后，检查权限是正确的

# ls -lh

total 3.5G

drwxrwxr-x. 7 oracle oinstall 4.0K Mar 13 14:47 app

-rw-r--r--. 1 root   root     3.5G Mar 15 22:28 app.tar.gz

1.2. B机器配置用户，系统参数，安装依赖包，用户环境变量，ASM磁盘

配置用户，系统参数，安装依赖包，用户环境变量
注：在第一步解压前做完，会发现权限都是正确的不用费心再改
root用户执行脚本

# /u01/app/oraInventory/orainstRoot.sh

# /u01/app/11.2.0/grid/root.sh

# /u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/roothas.pl

配置has

需要建立asm磁盘组

环境变量：

vi $ORACLE_HOME/dbs/init+ASM.ora

*.asm_diskstring='/dev/mapper/ora*'

*.asm_power_limit=1

*.diagnostic_dest='/u01/app/grid'

*.instance_type='asm'

*.large_pool_size=12M

*.remote_login_passwordfile='EXCLUSIVE'

确保将数据库的force_logging打开，设置为归档模式，数据库闪回打开

按之前的规划设置数据库的参数

主要是db_unique_name, log_archive_config, log_archive_dest_1,  log_archive_dest_2, log_archive_format, fal_server, fal_client, standby_file_management的设置，standby logfile的添加，密码文件的创建。

2.4 B机器 srvctl add数据库jyzhao_s

注：开始_s有问题，是因为添加指定的参数不足：
srvctl add database -d jyzhao_s -o /u01/app/oracle/product/11.2.0/db_1 -p  +DATA1/JYZHAO_S/spfilejyzhao_s.ora -n jyzhao -i jyzhao_s

srvctl modify database -d jyzhao_s -r PHYSICAL_STANDBY

三、DG切换测试

3.1 手动switchover

1主库切换成standby，启动到mount
select OPEN_MODE, DATABASE_ROLE, SWITCHOVER_STATUS, FORCE_LOGGING, DATAGUARD_BROKER, GUARD_STATUS from v$database;

alter database commit to switchover to physical standby;

2.备库切换成primary，启动到open

select OPEN_MODE, DATABASE_ROLE, SWITCHOVER_STATUS, FORCE_LOGGING, DATAGUARD_BROKER, GUARD_STATUS from v$database;

alter database commit to switchover to primary;

3.新的备库执行日志应用

alter database recover managed standby database using current logfile disconnect from session;

3.2 Data Guard Broker 快速switchover

SQL> show parameter dg_broker_start

------------------------------------ ----------- ------------------------------

dg_broker_start                      boolean     TRUE

配置dgmgrl

create CONFIGURATION jydb as primary database is jyzhao CONNECT IDENTIFIER IS jyzhao;

add database  jyzhao_s as CONNECT IDENTIFIER IS jyzhao_s MAINTAINED AS  PHYSICAL;    

enable configuration;
