ERROR:
ORA-01031: 权限不足

请输入用户名:

1、查看本地用户和组确认权限
将登录的用户添加进ora_dba权限组中
2、用可以登录的账号登录查看检查系统参数
SQL> show parameter password

NAME TYPE VALUE


remote_login_passwordfile string EXCLUSIVE
SQL> select * from v$pwfile_users;

USERNAME SYSDBA SYSOPER SYSASM


SYS TRUE TRUE FALSE
3、检查系统参数无sys记录,则创建密码文件,再次登录
C:\Users\Administrator>orapwd file="E:\oracle\product\11.2.0\dbhome_1\database/PWDVIDM.ora" password=oracle oswong entries=10

4、均无异常,或修改后报ORA-12641: 验证服务无法初始化,则:
查看sqlnet.ora文件中的SQLNET.AUTHENTICATION_SERVICES配置项
路径:E:\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN
修改为:SQLNET.AUTHENTICATION_SERVICES = (NTS)
正常连接
