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

bash 复制代码

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

复制代码

[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

bash 复制代码

[root@rac1 ~]# cat /etc/group
oinstall: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 grid
uid=1100(grid) gid=1005(oinstall) groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)
[root@rac1 ~]# id oracle
uid=1101(oracle) gid=1005(oinstall) groups=1005(oinstall),1001(dba),1002(asmadmin),1003(asmdba),1004(asmoper)

5.后续观察

alert日志中未再出现ORA-17503 ORA-27300 ORA-27301 ORA-27302告警信息
