前面介紹瞭如何通過RMAN Duplicate方式構建物理備用資料庫，本篇將演示如何利用Cloud Control構建物理備用資料庫。

1 軟體環境

• Oracle Linux 6.9
• Oracle 12.1.0.2
• Oracle Enterprise Management Cloud Control 12.1.0.4
• 主庫：odd.oracle.com，IP：192.168.1.105
• 備庫：even.oracle.com，IP：192.168.1.106

2 使用Cloud Control創建備庫

2.1 網路配置

2.1.1 主庫網路配置

1）監聽器配置

[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 備庫網路配置

1）監聽器配置

[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 測試網路

1）主庫測試

[oracle@odd ~]$ tnsping tns_odd

[oracle@odd ~]$ tnsping tns_even

2）備庫測試

[oracle@even admin]$ tnsping tns_odd

[oracle@even admin]$ tnsping tns_even

2.2 圖形界面創建備庫

1）登錄Cloud Control，進入目標>資料庫實例ORCL

2）輸入用戶名和口令，點擊登錄3）添加備用資料庫，點擊繼續

4）設置備份類型，點擊下一步

5）備份選項，不勾選，點擊下一步

6）備庫配置頁，點擊檢索按鈕

7）選擇目標備庫所在主機

8）填寫備庫信息後，點擊下一步

9）選擇備庫文件位置為OFA，點擊定製

10）檢查所有文件路徑，確保ORCL置換為ORCLDG，點擊確定

11）出現警告，點擊繼續

12）回到文件位置配置頁，點擊下一步

13）備庫配置頁面，更改備庫參數，點擊下一步

14）添加備庫複查頁面，如沒問題，點擊完成

15）點擊檢查作業鏈接

16）作業執行過程中

17）在Oracle資料庫>作業活動頁，可看到正在創建備庫

2.3 搭建完畢，驗證

2.3.1 主庫操作

1）查詢主庫角色信息

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）創建測試數據

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）查詢數據

SQL> select * from scott.test;



ID NAME

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

1 Alen

 2.3.2 備庫操作

1）查詢主庫角色信息

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）查詢數據

SQL> select * from scott.test;



ID NAME

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

1 Alen

綜上，就是使用Cloud Control搭建物理備用資料庫的整個過程
