如果oracle用户下的$ORACLE_HOME/bin/oracle文件的属主或权限出了问题，那么该如何修复呢？
如果可执行文件$ORACLE_HOME/bin/oracle的属主或权限设定出了问题，那么可能会造成很多问题。例如：无法登陆到数据库、ora-600错误、“TNS-12518: TNS:listener could not hand off client connection”、“Linux Error: 32: Broken pipe”、“ORA-12537: TNS:connection closed”、访问ASM磁盘出错、“ORA-15040: diskgroup is incomplete”等。
在安装了grid软件的情况下，oracle用户的$ORACLE_HOME/bin/oracle可执行文件的正确属主应该是oracle:asmadmin，并且权限必须有s才可以，而$GRID_HOME/bin/oracle文件的属主应该是grid:oinstall，如下所示：
[root@orclalhr ~]# ll /u01/app/11.2.0/grid/bin/oracle
-rwsr-s--x. 1 grid oinstall 203972117 Jan 5 2015 /u01/app/11.2.0/grid/bin/oracle
[root@orclalhr ~]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
-rwsr-s--x 1 oracle asmadmin 232399083 Apr 21 2015 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle如果权限或属主不对的话，那么解决办法也很简单，可以在root用户或grid用户下运行setasmgidwrap命令重新配置$ORACLE_HOME/bin/oracle可执行文件的权限和属主，也可以直接将oracle文件的权限修改为6751。
示例
[root@orclalhr ~]$ which setasmgidwrap
/u01/app/11.2.0/grid/bin/setasmgidwrap
[root@orclalhr ~]$ setasmgidwrap -o /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
[root@orclalhr ~]# chmod 6751 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
[root@orclalhr ~]# ll /u01/app/11.2.0/grid/bin/oracle
-rwsr-s--x. 1 grid oinstall 203972117 Jan 5 2015 /u01/app/11.2.0/grid/bin/oracle
[root@orclalhr ~]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
-rwsr-s--x 1 oracle asmadmin 232399083 Apr 21 2015 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
[root@orclalhr bin]# cd /u01/app/oracle/product/11.2.0/dbhome_1/bin/
[root@orclalhr bin]# which stat
/usr/bin/stat
