ASM的启动参数文件也可以放到ASM的DISKGROUP上吗？
按照 这个文档http://docs.oracle.com/cd/E11882_01/server.112/e18951/asminst.htm#OSTMG136
“
You can use an SPFILE or a text-based initialization parameter file (PFILE) as the Oracle ASM instance parameter file.
If you use an SPFILE in a clustered Oracle ASM environment,
then you must place the SPFILE in a disk group, on a shared raw device, or on a cluster file system.
Oracle recommends that the Oracle ASM SPFILE is placed in a disk group.
You cannot use a new alias created on an existing Oracle ASM SPFILE to start the Oracle ASM instance
”
我到疑问是ASM本身启动参数文件为何能放到DISKGROUP上呢？DISKGROUP只有在ASM启动完毕后，才能mount吧，启动之前都没有mount，怎么可能读得到呢？ 见这篇博文 ：http://www.askmaclean.com/archives/11gr2-rac-asm%E5%90%AF%E5%8A%A8%E6%8F%AD%E7%A7%98.html
