[Day 9]Oracle10g DG第四章Create physical standby DB by SQL-1

在上一篇介紹了使用EM建立physical standby,相信大家以愛上EM,但我還是得說明如何使用SQL來建置physical standby,畢竟這樣才能真正了解整個作業流程。
雖然這份文件在windows平台測試,和正式環境有差異(正式環境DG建置在R6 Unix平台),不過建置過程其實大同小異,只需注意幾個重點:

1.小弟正式環境採ASM,所以須注意路徑(+DATADG)
2.修改*.ora參數檔,control file請勿填寫由ASM自行建立
3.如使用NFS需使用Oracle規定指令才能mount成功
4.請再三確認rman backup及flash_recovery_area size,以免白花時間在備份上

確認primary and standby archive log mode

修改 archive mode
Shutdown immediate;
Startup mount;
Alter database archivelog;
Alter database open;

開啟FlashBack on(建議standby )
alter database flashback on;
開啟 forced logging

建立physics standby control file
alter database create standby controlfile as 'F:\standbybk\sdbcontrol01.ctl';

建立primary init.ora

複製該檔等等做為physics standby sdb2.ora

修改 pridg.ora
