【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：
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：

物理備庫：
db_name = oradg10g

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

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

二、 配置邏輯備庫引數檔案
[oracle@rhel6_lhr dbs]$ more initoraljdg.ora

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拷貝到相關路徑：
---拷貝物理備庫控制檔案
[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]$
--拷貝邏輯備庫控制檔案
[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

至此，物理備庫二搭建完成。
1.2 把物理備庫二轉化為邏輯備庫
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。
SQL> show parameter name

log_file_name_convert string oradg10g, oraljdg
service_names string oraljdg
SQL> alter database recover managed standby database cancel;
Database altered.
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。
