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 FAILEDORA-01565 error in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：?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……

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：

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。

网上也有类似的错误，但出现在升级到RAC的时候
