基於asm的單例項資料庫啟動時報錯ORA-15032 ORA-15063一例

ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"

--檢視錯誤資訊：
[oracle@rhl5 ~]$ oerr ora 15032
15032, 00000, "not all alterations performed"
// *Cause:  At least one ALTER DISKGROUP action failed.
// *Action: Check the other messages issued along with this summary error.
//
[oracle@rhl5 ~]$ oerr ora 15063
15063, 00000, "ASM discovered an insufficient number of disks for diskgroup \"%s\""
// *Cause:  ASM was unable to find a sufficient number of disks belonging to the
//          diskgroup to continue the operation.
// *Action: Check that the disks in the diskgroup are present and functioning,
//          that the owner of the ORACLE binary has read/write permission to
//          the disks, and that the ASM_DISKSTRING initialization parameter
//          has been set correctly.  Verify that ASM discovers the appropriate
//          disks by querying V$ASM_DISK from the ASM instance.

總結：此例是由於asm磁碟組的許可權出現問題導致asm磁碟無法正常掛載導致的。修改相應許可權即可。
