RACDBCA找不到共享磁盘

(一) 前言: 通过vmware workstation 走iscsi协议,安装RAC 集群架构,DBCA 时不能识别ASM 共享存储(按理来说这一版都是权限的问题)。同时,本想通过RMAN 做单实例 -- 迁移 --RAC, 单在创建ASM共享存储spfile参数文件时,一直报错,但是涉及的crs 服务,gri

(一) 前言: 通过vmware workstation 走iscsi协议,安装RAC 集群架构,DBCA 时不能识别ASM 共享存储(按理来说这一版都是权限的问题)。同时,本想通过RMAN 做单实例 --> 迁移 -->RAC, 单在创建ASM共享存储spfile参数文件时,一直报错,但是涉及的crs 服务,grid,oracle 权限都存在。
(二) 报错信息: SQL> create spfile='+DATA/DOMINIC/PARAMETERFILE/spfiledominic.ora' from pfile='/u01/soft/spfile_5_04'; create spfile='+DATA/DOMINIC/PARAMETERFILE/spfiledominic.ora' from pfile='/u01/soft/spfile_5_04' * ERROR at line 1: ORA-17502: ksfdcre:4 Failed to create file +DATA/DOMINIC/PARAMETERFILE/spfiledominic.ora ORA-01017: invalid username/password; logon denied
---这里,其实 只有真正的spfile参数放在ASM存储里,其他节点RAC1 ....RACn 都只是一个地址的映射。 RACDBCA找不到共享磁盘
当权限组正常的话,以上命令是可以执行,同时各节点在$ORACLE_HOME/dbs/initORACLE_SID.Z喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcmEgCjxicj4KCiBlY2hvICZxdW90O1NQRklMRT0="+DATA/ANQING/PARAMETERFILE/spfildominic.ora'" > /u01/app/oracle/product/11.2/db_1/dbs/initdominic1.ora
(三) 故障权限排查: oracle 家目录bin下权限,及所属组 [oracle@dominic3 ~]$ cd /u01/app/oracle/product/11.2/dbhome_1/bin/ [oracle@dominic3 bin]$ ll oracle -rwxrwxr-x 1 oracle asmadmin 239627031 May 17 17:32 oracle ---注意这里Oracle 权限,组, 路径!
grid 家目录bin下权限,及所属组 [oracle@dominic3 bin]$ cd /u01/app/11.2/grid/bin/ [oracle@dominic3 bin]$ ll oracle -rwsrwsr-x 1 grid oinstall 209914869 May 17 15:58 oracle ---注意这里Oracle 权限,组, 路径!
[root@dominic3 ~]# ls /dev/oracleasm/disks/* -l brw-rw---- 1 grid asmadmin 8, 17 May 27 15:37 /dev/oracleasm/disks/DATA01 brw-rw---- 1 grid asmadmin 8, 81 May 27 15:37 /dev/oracleasm/disks/DATA02 brw-rw---- 1 grid asmadmin 8, 97 May 27 15:37 /dev/oracleasm/disks/LOG01 brw-rw---- 1 grid asmadmin 8, 65 May 27 15:37 /dev/oracleasm/disks/LOG02 brw-rw---- 1 grid asmadmin 8, 113 May 27 15:37 /dev/oracleasm/disks/OCR01 brw-rw---- 1 grid asmadmin 8, 33 May 27 15:37 /dev/oracleasm/disks/OCR02 brw-rw---- 1 grid asmadmin 8, 49 May 27 15:37 /dev/oracleasm/disks/OCR03
[root@dominic3 ~]# su - grid [grid@dominic3 ~]$ sqlplus / as sysasm SQL> select GROUP_NUMBER,DISK_NUMBER,MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,PATH from v$asm_disk; SQL> / 2 0 CACHED MEMBER ONLINE NORMAL ORCL:DATA01 2 1 CACHED MEMBER ONLINE NORMAL ORCL:DATA02 3 0 CACHED MEMBER ONLINE NORMAL ORCL:LOG01 3 1 CACHED MEMBER ONLINE NORMAL ORCL:LOG02 1 0 CACHED MEMBER ONLINE NORMAL ORCL:OCR01 1 1 CACHED MEMBER ONLINE NORMAL ORCL:OCR02 1 2 CACHED MEMBER ONLINE NORMAL ORCL:OCR03
我把Oracle 及时添加到asmadmin 组也是这样 [grid@dominic3 ~]$ id oracle uid=1101(oracle) gid=1000(oinstall) groups=1000(oinstall),1200(asmadmin),1201(asmdba),1300(dba),1301(oper) [grid@dominic3 ~]$ id grid uid=1100(grid) gid=1000(oinstall) groups=1000(oinstall),1200(asmadmin),1201(asmdba),1202(asmoper)
-- grid 需要加入DBA 权限组, ASMDBA GRID,ORACLE ASM的SYSDBA OSDBA FOR ASM ASMADMIN GRID SYSASM OSASM ASMOPER GRID ASM的SYSOPER OSOPER FOR ASM RACDBCA找不到共享磁盘
最后的结果是: ASMDBA, ASMOPER, ASMADMIN 在创建grid 用户时,权限组设置颠倒所致。
