Windows下安裝dataGuard操作步驟文檔版本版本號日期說明編寫者審核者V1.02012-10-14文檔創建。呂萬里規劃保護模式：創建時使用默認設置，即最大性能模式，構建好后切換到最大保護模式。為了考慮主庫和物理備庫的切換，主庫也建standby redo logs。留出足夠的空間給歸檔日志，建議100G，后期將通過腳本定期刪除過期日志。同操作系統、oralce10g以上，開啟歸檔模式。配置步驟：1、配置安裝安裝主庫主庫先安裝數據庫和實例，備庫只安裝數據庫不裝實例 安裝前，先配置環境變量，例如ORACLE_BASE: e:oracleORACLE_HOME: %ORACLE_BASE%product10.2db_1ORACLE_SID: ORCL 然后，通過圖形界面安裝數據庫 安裝數據庫的實例，實例名：ORCL 修改主數據庫模式為force logging SQL alter database force logging;

分別在主庫和備庫配置監聽并啟動1) 配置主庫listener.ora如下： SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = E:/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) (SID_DESC =(GOLBAL_DBNAME = orcl)(ORACLE_HOME = E:/oracle/product/10.2.0/db_1)(SID_NAME = orcl) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1) (ADDRESS = (PROTOCOL = TCP)(HOST = test1)(PORT = 1521) ) ) 2) 在備庫使用netca配置listener.ora配置如下： SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = E:/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) (SID_DESC = (GOLBAL_DBNAME = orcl) (ORACLE_HOME = E:/oracle/product/10.2.0/db_1) (SID_NAME = orcl) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1) (ADDRESS = (PROTOCOL = TCP)(HOST = test2)(PORT = 1521) ) ) 3)主庫和備庫的tnsnames.ora都加入以下配置： PRIMARY = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = test1)(PORT = 1521) ) (CONNECT_DATA = (service_name = orcl) ) ) STANDBY = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = test2)(PORT = 1521) ) (CONNECT_DATA = (service_name = orcl) ) ) 備庫創建spfileSQL create spfile=E:/oracle/product/10.2.0/db_1/database/XXX.ORA frompfile=E:/oracle/product/10.2.0/admin/orcl/pfile/init.ora.XXX;啟動備庫SQL shutdown immediateSQL startup mount 備份方式可以采用最大可用模式或最大性能模式，對于最大可用模式需要創建standy redo log（步驟見下面），對于最大性能模式，可以不創建stany redo log。建議創建。首先在主庫切換一次日志，使備庫中記錄的原主庫的standby redo log信息被清除。 主庫執行： SQL alter system switch logfile;稍等一會，等在備庫中查詢v$standby_log沒有原來主庫standby log的信息返回時，再在備庫中添加standby redo log。 SQL select * from v$standby_log;SQLalter database add standby logfile group 4 E:/oracle/product/10.2.0/oradata/orcl/standbyredo04.log size 50M;
