DATAGUARD】 基於同一個主機建立物理備庫和邏輯備庫 (三)

blog文件結構圖:

wps3D8A.tmp 

 

 

  需求: 在同一臺機器配置10g單例項+物理dg+邏輯dg,即一個主庫上掛2個備庫,一個物理備庫,一個邏輯備庫,總體思路為:先搭建2臺物理dg,然後將其中的一臺轉換為邏輯dg

 

之前釋出過一步一步搭建 oracle 11gR2 rac + dg,這裡的dg為物理dg,但是實際自己使用過程中發現需要開3個虛擬機器,機器特卡,所以決定在同一臺機器上再搭建一臺物理和邏輯dg。

主庫:

db_name = oradg10g

db_unique_name/ORACLE_SID = oradg10g

Net Service Name = oradg10g

 

物理備庫:

db_name = oradg10g

db_unique_name/ORACLE_SID = orawldg

Net Service Name = orawldg

 

邏輯備庫:

db_name = oraljdg       --轉為邏輯備庫後的資料庫名,不能和主庫一致

db_unique_name/ORACLE_SID = oraljdg

Net Service Name = oraljdg

 

命令提示符:

# 表示以root使用者操作

$ 表示以oracle使用者操作

SQL> 表示登陸sqlplus操作

 

其它提示:

所有密碼都為lhr

 

 

1.1  先建立2物理備庫

--演示環境 

[oracle@rhel6_lhr ~]$ sqlplus -v

 

SQL*Plus: Release 10.2.0.4.0 - Production

 

[oracle@rhel6_lhr ~]$ cat /etc/issue

1.1.1  先建立一個主庫oradg10g

軟體安裝過程省略。。。。如有不會的,可以私聊。。。。。

 

我們直接採用dbca的靜默安裝方式來建立一個純淨的庫,關於dbca的靜默安裝方式參考:http://blog.itpub.net/26736162/viewspace-1448220/

二、 為主庫新增standby redo log

 

--為主庫新增standby redo log,簡要描述一下standby redo log的作用 

--實際上就是與主庫接收到的重做日誌相對應,也就是說備庫呼叫RFS程式將從主庫接收到的重做日誌按順序寫入到standby logfile 

--在主庫建立standby logfile是便於發生角色轉換後備用 

--sandby redo log建立原則: 

--a)、確保standby redo log的大小與主庫online redo log的大小一致   

--b)、如主庫為單例項資料庫:standby redo log組數=主庫日誌組總數+1 

--c)、如果主庫是RAC資料庫:standby redo log組數=(每執行緒的日誌組數+1)*最大執行緒數 

--d)、不建議複用standby redo log,避免增加額外的I/O以及延緩重做傳輸

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/u03/app/oracle/admin/orawldg/udump'

 

 

二、 配置邏輯備庫引數檔案

 

 

[oracle@rhel6_lhr dbs]$ more initoraljdg.ora

*.audit_file_dest='/u03/app/oracle/admin/oraljdg/adump'

*.background_dump_dest='/u03/app/oracle/admin/oraljdg/bdump'

*.compatible='10.2.0.3.0'

*.control_files='/u04/oradata/oraljdg/control01.ctl','/u04/oradata/oraljdg/control02.ctl','/u04/oradata/oraljdg/control03.ctl'

*.core_dump_dest='/u03/app/oracle/admin/oraljdg/cdump'

*.db_block_size=8192

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_file_name_convert='oradg10g','oraljdg'

*.db_name='oradg10g'

*.db_recovery_file_dest='/u03/app/oracle/flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.db_unique_name='oraljdg'

*.fal_client='oraljdg'

*.fal_server='oradg10g'

*.job_queue_processes=50

*.log_archive_config='DG_CONFIG=(oradg10g,orawldg,oraljdg)'

*.log_archive_dest_1='location=/u04/arch/oraljdg VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=oraljdg'

*.log_archive_dest_state_1='ENABLE'

*.log_archive_format='log_%t_%s_%r.arc'

*.log_file_name_convert='oradg10g','oraljdg'

*.open_cursors=300

*.processes=500

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=200M

*.standby_file_management='AUTO'

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/u03/app/oracle/admin/oraljdg/udump'

 

 

 

 

 

 

三、 建立物理和邏輯備庫的相關路徑

---物理dg路徑

mkdir -p /u03/app/oracle/admin/orawldg/adump

mkdir -p /u03/app/oracle/admin/orawldg/bdump

mkdir -p /u03/app/oracle/admin/orawldg/cdump

mkdir -p /u03/app/oracle/admin/orawldg/udump

mkdir -p /u04/oradata/orawldg/

mkdir -p /u04/arch/orawldg

 

 

--邏輯dg路徑

mkdir -p /u03/app/oracle/admin/oraljdg/adump

mkdir -p /u03/app/oracle/admin/oraljdg/bdump

mkdir -p /u03/app/oracle/admin/oraljdg/cdump

mkdir -p /u03/app/oracle/admin/oraljdg/udump

mkdir -p /u04/oradata/oraljdg/

mkdir -p /u04/arch/oraljdg/

 

 

四、 控制檔案

按照引數檔案中的定義將控制檔案複製到相關路徑:

 

---複製物理備庫控制檔案

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/orawldg/control01.ctl

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/orawldg/control02.ctl

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/orawldg/control03.ctl

[oracle@rhel6_lhr backup]$

 

--複製邏輯備庫控制檔案

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/oraljdg/control01.ctl

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/oraljdg/control02.ctl

[oracle@rhel6_lhr backup]$ cp /u04/backup/control01.ctl /u04/oradata/oraljdg/control03.ctl

[oracle@rhel6_lhr backup]$

至此,物理備庫搭建完成。

 

 

1.2  物理備庫轉化為邏輯備庫

1.2.1  確定哪些表不支援

以下sql可以確定哪些表不支援(不被支援的表通常是由於列的定義包含了不支援的資料型別)

SQL>  SELECT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_NOT_UNIQUE

  2  WHERE (OWNER, TABLE_NAME) NOT IN (SELECT DISTINCT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_UNSUPPORTED)

  3  AND BAD_COLUMN = 'Y';

 

OWNER                          TABLE_NAME

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

TSMSYS                         SRS$

 

SQL>

 

檢視主庫是否啟用了supplemental logging特性如果未啟動,需要開啟:

SQL> select supplemental_log_data_pk,supplemental_log_data_ui from v$database;

 

SUP SUP

--- ---

NO  NO

 

SQL> alter database add supplemental log data (PRIMARY KEY,unique INDEX) columns;

 

Database altered.

 

SQL>  select supplemental_log_data_pk,supplemental_log_data_ui from v$database;

 

SUP SUP

--- ---

YES YES

 

SQL>

 

 

 

 

1.2.2  停用備庫MRP程式  

  對於將物理備庫切換到邏輯備庫,我們需要在主庫構建LogMiner字典及啟用補充日誌,因此應先停用邏輯備庫的MRP程式,避免產生額外的redo apply,  邏輯備用資料庫在後臺使用LogMiner來提取生成SQL Apply事務必須的重做資料,在建立Log Miner字典之前,我們必須停止備用資料庫上的管理恢復,以確保我們只應用包含LogMiner字典的重做資料:

  如果正在使用Broker管理現有的物理備庫,應先在Broker中禁用目標資料庫。

1.2.3  主庫構建LogMiner字典

這裡字典表空間儘量大一點,不然邏輯dg搭建可能不能同步,build過程會等到所有事務都完成,這個步驟需要使用閃回查詢技術對資料字典資訊執行一致性讀,故undo_retention需要設定時間長一些,3600以上,不然可能碰到ora-1555
