12cDataGuard构建物理备用数据库（Cloud Control方式）

Posted 2020-12-22 alen-liu-sz

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/oracle

2）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/oracle

2）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_even

2）备库测试

[oracle@even admin]$ tnsping tns_odd

[oracle@even admin]$ tnsping tns_even

2.2 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 ENABLED

2）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 Alen

 2.3.2 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 ENABLED

 2）查询数据

SQL> select * from scott.test;



ID NAME

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

1 Alen

综上，就是使用Cloud Control搭建物理备用数据库的整个过程
