【12c】DataGuard构建物理备用数据库（Cloud Control方式）
前面介绍了如何通过RMAN Duplicate方式构建物理备用数据库，本篇将演示如何利用Cloud Control构建物理备用数据库。
1 软件环境
- Oracle Linux 6.9
- Oracle 12.1.0.2
- Oracle Enterprise Management Cloud Control 12.1.0.4
- 主库：odd.oracle.com，IP：192.168.1.105
- 备库：even.oracle.com，IP：192.168.1.106
2 使用Cloud Control创建备库
2.1 网络配置
2.1.1 主库网络配置
1）监听器配置
[oracle@odd admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = /u01/app/oracle/product/12.1.0/dbhome_1)
(SID_NAME = ORCL)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = odd.oracle.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle2）TNS配置
[oracle@odd admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
TNS_ODD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.105)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)
TNS_EVEN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.106)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCLDG)
)
)2.1.2 备库网络配置
1）监听器配置
[oracle@even admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ORCLDG)
(ORACLE_HOME = /u01/app/oracle/product/12.1.0/dbhome_1)
(SID_NAME = ORCLDG)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = even.oracle.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle2）TNS配置
[oracle@even admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
TNS_ODD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.105)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)
TNS_EVEN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.106)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCLDG)
)
)2.1.3 测试网络
1）主库测试
[oracle@odd ~]$ tnsping tns_odd
[oracle@odd ~]$ tnsping tns_even2）备库测试
[oracle@even admin]$ tnsping tns_odd
[oracle@even admin]$ tnsping tns_even2.2 图形界面创建备库
1）登录Cloud Control，进入目标>数据库实例ORCL
2）输入用户名和口令，点击登录
3）添加备用数据库，点击继续
4）设置备份类型，点击下一步
5）备份选项，不勾选，点击下一步
6）备库配置页，点击检索按钮
7）选择目标备库所在主机
8）填写备库信息后，点击下一步
9）选择备库文件位置为OFA，点击定制
10）检查所有文件路径，确保ORCL置换为ORCLDG，点击确定
11）出现警告，点击继续
12）回到文件位置配置页，点击下一步
13）备库配置页面，更改备库参数，点击下一步
14）添加备库复查页面，如没问题，点击完成
15）点击检查作业链接
16）作业执行过程中
17）在Oracle数据库>作业活动页，可看到正在创建备库
2.3 搭建完毕，验证
2.3.1 主库操作
1）查询主库角色信息
SQL> select name,open_mode,database_role,db_unique_name,dataguard_broker from v$database;
NAME OPEN_MODE DATABASE_ROLE DB_UNIQUE_NAME DATAGUAR
--------- -------------------- ---------------- ------------------------------ --------
ORCL READ WRITE PRIMARY ORCL ENABLED2）创建测试数据
SQL> create table scott.test(id number,name varchar2(100));
Table created.
SQL> insert into scott.test values(1,'Alen');
1 row created.
SQL> commit;
Commit complete.3）查询数据
SQL> select * from scott.test;
ID NAME
---------- ----------------------------------------------------------------------------------------------------
1 Alen2.3.2 备库操作
1）查询主库角色信息
SQL> select name,open_mode,database_role,db_unique_name,dataguard_broker from v$database;
NAME OPEN_MODE DATABASE_ROLE DB_UNIQUE_NAME DATAGUAR
--------- -------------------- ---------------- ------------------------------ --------
ORCL READ ONLY WITH APPLY PHYSICAL STANDBY ORCLDG ENABLED2）查询数据
