此报错对系统运行没有什么影响，排查及解决办法如下（参考官方文档 KB96677）：

1.查看oracle及grid用户信息，正常

[root@rac1 ~]# id oracleuid=1101(oracle)gid=1005(oinstall)groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)[root@rac1 ~]# id griduid=1100(grid)gid=1005(oinstall)groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)

2.查看/etc/group文件中oinstall信息

发现现象与官方文档一致，oinstall处缺少oracle及grid用户

3.解决方法

将grid与oracle用户追加到附加组oinstall

[root@rac1 ~]# usermod -a -G oinstall oracle [root@rac1 ~]# usermod -a -G oinstall grid

4.验证/etc/group结果，oinstall组信息正常

[root@rac1 ~]# cat /etc/groupoinstall:x:1005:oracle,grid dba:x:1001:grid,oracle asmadmin:x:1002:grid,oracle asmdba:x:1003:grid,oracle asmoper:x:1004:grid,oracle###grid及oracle用户信息查出来没有改变，与原来一致[root@rac1 ~]# id griduid=1100(grid)gid=1005(oinstall)groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)[root@rac1 ~]# id oracleuid=1101(oracle)gid=1005(oinstall)groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)
