环境：RHEL 5.1 32位 ，Oracle 11.2.01
在安装11G RAC建库的时候DBCA出现
ORA-1503 CREATE CONTROLFILE FAILED
ORA-01565 error in identifying file '+DATA/rac/dataile/datfile/system'
解决办法：
1、首先检查ASM实例起来没有
oracle@rac1[/home/oracle]srvctlstatus asm -n rac1
ASM is running on rac1
oracle@rac1[/home/oracle]srvctlstatus asm -n rac2
ASM is running on rac2
补充案例：
案例1：阵列坏了块硬盘导至ora-01078 ora-01565 ora-17503 ora-15077一例解决
链接：http://www.aixchina.net/home/space.php?uid=20260&do=blog&id=24793
步骤：先看在ASMCMD查看磁盘状态（lsdsk）,然后重启ASM实例
案例2：因为磁盘DISMOUNTED，出现了问题，导致这样的错误 ORA-01078;ORA-01565;ORA-17503;ORA-15077
SQL> startup;
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DG1/devdb/spfiledevdb.ora'
ORA-17503: ksfdopn:2 Failed to open file +DG1/devdb/spfiledevdb.ora
ORA-15077: could not locate ASM instance serving a required diskgroup
……
export ORACLE_SID=+ASM1
sqlplus / as sysdba
SQL>shutdown immediate;
……
SQL>startup;
SQL>select name,state from v$asm_diskgroup;

SQL>alter diskgroup DG1 mount;
2、检查权限问题
节点1：
oracle@rac1[/home/oracle]ls-l /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
-r-sr-s--x 1 oracle asmadmin 173515925 Dec 24 03:15 /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
oracle@rac1[/home/oracle]chmod6751 /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
oracle@rac1[/home/oracle]ls-l /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
-rwsr-x--x 1 oracle asmadmin 173515925 Dec 24 03:15 /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
节点2：
[oracle@rac2 ~]# ls -l /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
-rwsr-s--x 1oracle oinstall173515925 Dec 24 03:31 /oracle/app/oracle/product/11.2.0/db_1/bin/oracle ---问题所在
[root@rac2 ~]# su - grid
grid@rac2[/home/grid]ls-l /oracle/app/crs_home/bin/oracle
-rwsr-s--x 1 grid oinstall 152462748 Dec 24 01:20 /oracle/app/crs_home/bin/oracle
修改权限：
grid@rac2[/oracle/app/crs_home/bin]setasmgidwrapo=/oracle/app/oracle/product/11.2.0/db_1/bin/oracle
grid@rac2[/oracle/app/crs_home/bin]ls-l /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
-r-sr-s--x 1 oracle asmadmin 173515925 Dec 24 03:31 /oracle/app/oracle/product/11.2.0/db_1/bin/oracle
到此解决。
其他摘要：
网上也有类似的错误，但出现在升级到RAC的时候

ORA-01565: error in identifying file '+DATA/spfilerac.ora'
环境：DB:11.2.0.2 RAC OS:RHEL 5.6
今天在做11GR2下面单机升级到RAC时遇到下面的问题
