解决sqlplus as sysdba遇到ORA-01017 的问题

今天发现sqlplus "/as sysdba"无法登陆的问题，后来发现是由于oracle用户不数据DBA组导致的

[oracle@scaqan04dv0208 ~]$ source GZhouDB.env
[oracle@scaqan04dv0208 ~]$ sqlplus "/as sysdba"

SQL*Plus: Release 19.0.0.0.0 - Production on Wed Jun 17 08:00:01 2020
Version 19.7.0.0.0

ERROR:
ORA-01017: invalid username/password; logon denied


[oracle@scaqan04dv0108 ~]$ id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1004(asmdba),1005(asmoper),1006(asmadmin),1002(dba),1003(racoper)
由于有一次运行usermod -G时疏漏了1002这个组，导致无法连接
不小心remove了1002 dba这个组

如果oracle不属于dba组，那么srvctl也会出现问题，并且错误的指示性不强

[root@scaqan04dv0108 ~]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1004(asmdba),1005(asmoper),1006(asmadmin),1002(dba),1003(racoper)
[root@scaqan04dv0108 ~]# usermod -G 1001,1003,1004,1005,1006 oracle
[root@scaqan04dv0108 ~]# su - oracle
