ORA-12638: 身份证明检索失败
来源:互联网 发布:php开发用什么框架 编辑:程序博客网 时间:2024/05/16 11:31
the NTS option makes the Oracle client attempt to use your current Windows domain credentials to authenticate you with the Oracle server. This could fail for a couple of reasons:
- The Oracle server is not configured to support Windows authentication
- The credentials you use to login to your local machine are not sufficient to allow you to login to the server.
In my case, it was the later. Despite the fact that I had told the client to use a different user name and password, it was still attempting to login using my domain credentials first. This failed because I was logged on to my local machine using my normal domain credentials rather than my administrator account.
Replacing the line:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
with
SQLNET.AUTHENTICATION_SERVICES= (NONE)
in sqlnet.ora resolved the issue by disabling local support for authenticating using Windows credentials.
ORA-12638: 身份证明检索失败 的解决办法
今天在使用应用程序连接Oracle时碰到了 “ORA-12638: 身份证明检索失败” 错误,到网上搜索了一下,是因为Oracle的高级安全性验证导致,解决办法如下:
开始 -> 程序 -> Oracle -> Configuration and Migration Tools ->
Net Manager→本地→概要文件→Oracle高级安全性→验证→去掉所选方法中的 "NTS" 就可以了.
