事先备份好asm的spfile

[grid@rac2 ~]$asmcmd

ASMCMD> spget

+ocr/rac/asmparameterfile/REGISTRY.253.840115871

ASMCMD> spcopy +ocr/rac/asmparameterfile/REGISTRY.253.840115871 /home/grid/asm.ora

ASMCMD> exit

创建pfile

[grid@rac2 ~]$ cat asmpfile.ora

#spfile=+ocr/rac/asmparameterfile/REGISTRY.253.840115871

spfile=/home/grid/asm.ora

利用pfile启动

[grid@rac2 ~]$ sqlplus / as sysasm

查看spget确认spfile路径

[grid@rac2 ~]$ asmcmd

ASMCMD> spget

/home/grid/asm.ora

ASMCMD> exit

修改spfile路径

[grid@rac2 ~]$ cat asmpfile.ora
