Oracle: Oracle 11gR2
在Oracle 11gR2,做文件系統(tǒng)向ASM磁盤組遷移的項目中,Oracle用戶無法訪問ASM磁盤組,在Oracle 11gR2中g(shù)rid用戶管理ASM instance,經(jīng)檢查發(fā)現(xiàn)以下錯誤:
SQL> select name,state from v$asm_diskgroup;
NAME STATE
------------------------------ -----------
DATA MOUNTED
FRA MOUNTED
SQL> show parameter control
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string +FRA
control_management_pack_access string DIAGNOSTIC+TUNING
SQL>
控制文件遷移,Oracle用戶無法訪問FRA磁盤組:

解決方案:
1、查看$ORACLE_HOME/bin/oracle
[oracle@node1 ~]$ ls -l /u01/app/oracle/product/11.2.0/db_1/bin/oracle
-rwxr-x--x 1 oracle asmadmin 173515991 Mar 15 14:14 /u01/app/oracle/product/11.2.0/db_1/bin/oracle
---- 對于$ORACLE_HOME/bin/oracle的可執(zhí)行文件,grid用戶應(yīng)該有權(quán)限訪問,修改權(quán)限:
[root@node1 ~]# chmod 6751 /u01/app/oracle/product/11.2.0/db_1/bin/oracle
[oracle@node1 ~]$ ls -l /u01/app/oracle/product/11.2.0/db_1/bin/oracle
-rwsr-s--x 1 oracle asmadmin 173515991 Mar 15 14:14 /u01/app/oracle/product/11.2.0/db_1/bin/oracle
2、查看$GRID_HOME/bin/oracle
[root@node1 ~]# ls -l /u01/11.2.0/grid/bin/oracle
-rwxrwxr-x 1 grid oinstall 152462814 Mar 15 14:00 /u01/11.2.0/grid/bin/oracle
修改權(quán)限:
[root@node1 ~]# chmod +s /u01/11.2.0/grid/bin/oracle
[root@node1 ~]# ls -l /u01/11.2.0/grid/bin/oracle
-rwsrwsr-x 1 grid oinstall 152462814 Mar 15 14:00 /u01/11.2.0/grid/bin/oracle
[root@node1 ~]#
------ 至此,問題解決,Oracle用戶可以正常訪問ASM diskgroup !
