--分别设置oracle和grid用户的oracle文件权限为6751，如果属主不对记得修改属主

chmod 6751 /oracle/app/12.1.0/grid/bin/oracle

上面报错的原因是启动数据库的命令一直在sqlplus中的没有退出用户重新进入导致的

如果在修改oracle文件时数据库已经启动，那么再登陆数据库执行命令会提示如下：

SQL> shutdown immediate;

ERROR:

ORA-27140: attach to post/wait facility failed

ORA-27300: OS system dependent operation:invalid_egid failed with status: 1

ORA-27301: OS failure message: Operation not permitted

ORA-27302: failure occurred at: skgpwinit6

ORA-27303: additional information: startup egid = 1100 (oinstall), current egid = 1201 (asmadmin)

这里修改回oracle:oinstall属组后可以正常关闭数据库
