ORA-01031: insufficient privileges

首先想到就是sqlnet.ora配置有问题。于是查看了下sqlnet.ora内容，如下：

# 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)

看到这里想必大家都明白了，原来是域认证没有通过。
处理办法非常简单，将该用户加入到ora_dba这个组中即可
