操作系统验证报ORA-01017

一个测试库，sqlplus登录时无法使用os验证

$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0  Production on Wed Jun 29 16:51:32 2021
Copyright (c) 1982, 2013, Oracle.  All rights reserved.
ERROR:
ORA-01017: invalid username/password; logon denied

查看sqlnet.ora 无配置,通过情况下默认是启用os验证的,也可以显示指定：

SQLNET.AUTHENTICATION_SERVICES = (ALL) 

查看oracle用户

$ id oracle
uid=54321(oracle) gid=54321(oinstall) 组=54321(oinstall)

缺少dba组

usermod -G oinstall,dba oracle
