当我尝试以sysdba身份连接时发生Oracle错误：凭据检索失败

Question

大家好我总是有这个错误“ORA-12638：凭据检索失败”当我尝试在我的oracle数据库中连接为sysdba 谁能帮帮我？

我的sqlnet.ora内容：

# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES = (NTS)

Answer 1

您的sqlnet.ora文件中似乎有NTS身份验证 替换：

SQLNET.AUTHENTICATION_SERVICES = (NTS)

使用：

SQLNET.AUTHENTICATION_SERVICES = (NONE)
