檢視grid與oracle使用者下面的oracle檔案的許可權


檢視grid使用者下面的oracle的許可權 
[root@11rac5 log]# su - grid 
[grid@11rac5 ~]$ ls -l $ORACLE_HOME/bin/oracle 
-rwxr-x--x 1 grid oinstall 200678430 Oct  9 13:35 /u01/app/11.2.0/grid/bin/oracle 
許可權不正確，修改。 
[grid@11rac5 ~]$ chmod 6751 $ORACLE_HOME/bin/oracle 
[grid@11rac5 ~]$ ls -l $ORACLE_HOME/bin/oracle 
-rwsr-s--x 1 grid oinstall 200678430 Oct  9 13:35 /u01/app/11.2.0/grid/bin/oracle 
檢視oracle使用者下面的oracle許可權 
[oracle@11rac5 trace]$ ls -l $ORACLE_HOME/bin/oracle 
-rwsr-x--x 1 oracle asmadmin 228886426 Oct  9 15:29 /u01/app/oracle/product/11.2.0/db_2/bin/oracle 
 
在grid使用者下面修改 
[oracle@11rac5 trace]$ su - grid

[grid@11rac5 ~]$ cd $ORACLE_HOME/bin/ 
[grid@11rac5 bin]$ set

-rwsr-s--x 1 oracle asmadmin 228886426 Oct  9 15:29 /u01/app/oracle/product/11.2.0/db_2/bin/oracle
