creating oracle10g data guard using rman(physical db)

1,對主庫進行一個全庫備份（利用rman)
    backup as copy incremental level 0 database format '/oracle/rmanbak/%Ubak' tag 'test rman standby db';
2,根據主庫生成備庫pfile(且根據備庫實際情況修正相關引數）
    adding db_unique_name
   create pfile='/oracle/rmanbak/initrman.ora' from spfile;
3,啟動主庫到mount，利用rman生成備庫控制檔案，且之後進行歸檔操作
   startup force mount
   backup current controlfile format '/oracle/rmanbak/%D_u_rmancontrolbak';
   sql 'alter database open';
   sql 'alter system archive log curent';
   sql 'alter system switch logfile';
   backup archivelog all format '/oracle/rmanbak/%d_%u_archivebak';
4,把以上諸步生成的rman備份，利用scp傳到備庫對應目錄（為了簡易，我主備庫目錄結構完全一致，請根據pfile，依次構建dump及db_recovery_dest，儲存rman的目錄.
5,在備庫上,利用rman進行生成備庫
    注：先用以上生成的pfile,把備庫啟到nomount
       startup nomount pfile
    然後
       rman target sys/system@centos auxiliary sys/system
       
    最後貼上我真正開工的指令碼，供後記
-bash-3.1$ rman target sys/system@centos auxiliary  sys/system

6,在新生成的備庫上，變更standby_file_management=auto,從主庫進行相關dml,檢視備庫是否正常，其它操作同以前，不再多述
