上面是使用預設方式建立好的Standalone單資料庫環境，使用ASM作為儲存方式，OCRVDISK儲存了ASM例項的引數檔案。
如果想Standalone單例項資料庫環境中不使用ASM作為ASM例項引數檔案的存放方式，推薦的做法是先按照預設的要求，建立好ASM磁碟組，ASM例項的引數檔案會存放到該ASM磁碟組中，例如上面的OCRVDISK磁碟組。之後再透過下面的方式將ASM例項的引數檔案遷移到本地檔案系統。
2.使用srvctl modify asm修改SPFILE位置。
# pwd
/u01/app/11.2.0/grid/bin
# ./srvctl modify asm -h
Modifies the configuration for ASM.
Usage: srvctl modify asm [-l <lsnr_name>] [-p <spfile>] [-d <asm_diskstring>]
-l <lsnr_name> Listener name
-p <spfile> Server parameter file path
-d <asm_diskstring> ASM diskgroup discovery string
-h Print usage
# ./srvctl config asm
ASM home: /u01/app/11.2.0/grid
ASM listener: LISTENER
Spfile: +OCRVDISK/asm/asmparameterfile/registry.253.793652513
ASM diskgroup discovery string:
# su - grid
$ cd /u01/app/11.2.0/grid/dbs/
$ ls
ab_+ASM.dat hc_+ASM.dat init.ora orapw+ASM
當前並沒有ASM例項的SPFILE引數檔案。
$ srvctl modify asm -p /u01/app/11.2.0/grid/dbs/spfile+ASM.ora
srvctl modify asm的操作必須在grid使用者下完成。
3.重啟Grid，檢驗modify效果。

4.刪除儲存ASM例項引數檔案的磁碟組。

Diskgroup dropped.
刪除OCRVDISK磁碟組。
5.DROP OCRVDISK磁碟組之後觀察Grid重啟效果。

ASM例項正常啟動。
$ cd $GRID_HOME/dbs
$ ls

從上面的輸出可以看出，srvctl modify asm命令並不會建立例項的SPFILE引數檔案，但是srvctl add asm命令會為ASM例項建立預設值的引數檔案，這點是有差別的，所以我們還可以透過執行srvctl remove asm和srvctl add asm命令實現對ASM引數檔案位置的修改，且還建立相應位置的引數檔案。
從上面的例子看出，即使沒有ASM例項的引數檔案，ASM例項依然可以正常啟動，Oracle應該為ASM例項設定了預設的啟動引數。

從這個例子可以看出，修改現存環境的ASM引數檔案位置，首先是建立新位置的SPFILE檔案，之後使用srvctl modify asm命令調整SPFILE的位置，最後重啟Grid軟體以驗證ASM引數位置修改效果。
