How to move ASM spfile to a different disk group [ID 1082943.1]
适用于 11R2
有两种方法：采用 create pfile/spflie 通过中间文件迁移；适用 asmcmd 自带的 spcopy 命令；第一种方法比较简单，步骤如下
create pfile= /tmp/pfile+ASM.ora from spfile;
create spfile= +PLAY from pfile= /tmp/pfile+ASM.ora
crsctl stop has
crsctl start has -- 重启验证
下面介绍一下 spcopy 命令
由于 GPnP profile 记录有 spfile 路径信息，因此需添加 - u 选项自动更新
1. Copy spfile with -u option - to update GPnP profile in RAC environment
$ asmcmd spget
+DATA/asm/asmparameterfile/registry.253.722601213
$ asmcmd lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Votin g_files Name
MOUNTED EXTERN N 512 4096 1048576 14658 9814 0 9814 0 N DATA/
MOUNTED EXTERN N 512 4096 1048576 9772 8507 0 8507 0 N PLAY/
MOUNTED EXTERN N 512 4096 1048576 9772 9212 0 9212 0 N RECO/
$ asmcmd spcopy -u +DATA/asm/asmparameterfile/registry.253.722601213 +PLAY/spfileASM.ora
2. Restart the HA stack to verify that ASM starts up fine with copiedspfile
$ crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on server
CRS-4133: Oracle High Availability Services has been stopped.
$ crsctl start has
CRS-4123: Oracle High Availability Services has been started.
$ asmcmd spget
+PLAY/spfileASM.ora
3. Remove the original spfile
$ asmcmd ls -l +DATA/asm/asmparameterfile
Type Redund Striped Time Sys Name
ASMPARAMETERFILE UNPROT COARSE JUN 25 10:00:00 Y REGISTRY.253.722601213
$ asmcmd rm +DATA/asm/asmparameterfile/registry.253.722601213
NOTE: The disk group that holds ASM spfile has to have COMPATIBLE.ASM value of 11.2 or higher.感谢各位的阅读，以上就是“ASM 下如何迁移 spfile”的内容了，经过本文的学习后，相信大家对 ASM 下如何迁移 spfile 这一问题有了更深刻的体会，具体使用情况还需要大家实践验证。这里是丸趣 TV，丸趣 TV 小编将为大家推送更多相关知识点的文章，欢迎关注！
