【解决方法】

         修改$ORACLE_HOME/bin/oracle文件的权限。

         修改之前的权限：

         [oracle@orclbin]$ ls -l oracle

         -rwxr-x--x1 oracle oinstall 232399083 May 12  2013oracle

         修改之后的权限：

         [oracle@orclbin]$ chmod 6751 oracle

         [oracle@orclbin]$ ls -l oracle   

         -rwsr-s--x1 oracle oinstall 232399083 May 12  2013oracle



【问题原因】

         未知。服务器发生过外部电源断电故障，但是修改完bin/oracle文件权限之后，尝试了reboot服务器，没有发生异常。



【参考信息】

1. Check and correct the permission on/var/tmp/.oracle directory. Permissions on this directory should be 777 withsticky bit set.



# chmod 01777 /var/tmp/.oracle

2. Check and correct permissions on$ORACLE_HOME/bin/oracle binary and make sure that it is set to 6751.

$ chmod 6751 $ORACLE_HOME/bin/oracle
