ora-12641 ora-12699 验证服务无法初始化

应该是网络问题,在错误手册上,这个问题的标准代码应该为 tns-12641(ora-12500到ora-12699的错误,应该是tns-12500到tns-12699).网络问题,从网络方面着手了.

查了metalink,描述如下:

Problem Description:

================

You are trying to connect to a database and you receive one of the

following errors:

ORA-12641: TNS:authentication service failed to initialize

Cause: The authentication service failed during initialization.

Action: Enable tracing to determine the exact error.

– OR -

ORA-12666: Dedicated server: outbound transport protocol different

from inbound

Cause: The protocol specified for an externally-identified outbound

connection from a dedicated server (database link) was not

the same as that used for the inbound connection. It is not

possible for SQL*Net to authenticate a proxy connection that

uses a protocol that is different from that which was used

for the connection to the dedicated server.

Action: Specify the same protocol in the SQL*Net connect string or

alias for the outbound connection as that used for the inbound

connection.

metalink上的说法是ora-12666错误也是和这个一样的错误.
解决的方法,也算比较简单的
将sqlnet.ora文件中的SQLNET.AUTHENTICATION_SERVICES = (TNS)修改为SQLNET.AUTHENTICATION_SERVICES = (NONE)

然后再来连接数据库,通的.ok,问题暂时解决
