当rman连接不上 ... sqlnet.ora

在oracle安装目录下 找到  .   sqlnet.ora   ,内容大致如下 

# sqlnet.ora Network Configuration File: E:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora

# Generated by Oracle configuration tools.


# 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)


NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

SQLNET.AUTHENTICATION_SERVICES= (NTS)

估计只有我自己看得懂了。。。。。
