上面是使用默认方式创建好的Standalone单数据库环境，使用ASM作为存储方式，OCRVDISK存储了ASM实例的参数文件。
如果想Standalone单实例数据库环境中不使用ASM作为ASM实例参数文件的存放方式，推荐的做法是先按照默认的要求，创建好ASM磁盘组，ASM实例的参数文件会存放到该ASM磁盘组中，例如上面的OCRVDISK磁盘组。之后再通过下面的方式将ASM实例的参数文件迁移到本地文件系统。
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
-l
-p
-d
-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
当前并没有ASM实例的SPFILE参数文件。
$ srvctl modify asm -p /u01/app/11.2.0/grid/dbs/spfile+ASM.ora
srvctl modify asm的操作必须在grid用户下完成。
3.重启Grid，检验modify效果。

5.DROP OCRVDISK磁盘组之后观察Grid重启效果。

ASM实例正常启动。
$ cd $GRID_HOME/dbs
$ ls
ab_+ASM.dat hc_+ASM.dat init.ora orapw+ASM
从上面的输出可以看出，srvctl modify asm命令并不会创建实例的SPFILE参数文件，但是srvctl add asm命令会为ASM实例创建默认值的参数文件，这点是有差别的，所以我们还可以通过执行srvctl remove asm和srvctl add asm命令实现对ASM参数文件位置的修改，且还创建相应位置的参数文件。
从上面的例子看出，即使没有ASM实例的参数文件，ASM实例依然可以正常启动，Oracle应该为ASM实例设定了默认的启动参数。

从这个例子可以看出，修改现存环境的ASM参数文件位置，首先是创建新位置的SPFILE文件，之后使用srvctl modify asm命令调整SPFILE的位置，最后重启Grid软件以验证ASM参数位置修改效果。
