sqlnet.authentication_services = (NONE)作者: microsesame 时间: 2003-01-16 09:30 标题: 请教一个密码问题。 问题解决了，太感谢了。
不过我还想问个问题。我装过几次oracle，每次都能直接用sys或system直接登陆，也就是说，在sqlnet.ora中设置如下SQLNET.AUTHENTICATION _SERVICES=(NONE)。 但这次却变成了SQLNET.AUTHENTICATION _SERVICES=(NTS)。这是怎么回事？
我的安装顺序是WIN2000 ,SP2,ORACLE 8.16 ,金山毒霸，SP3 和我的安装是不是有关系。请各位大虾指点。
再次感谢大家了！！！作者: CCBZZP 时间: 2003-01-16 09:45 标题: 请教一个密码问题。 建議升級SP作者: microsesame 时间: 2003-01-16 10:01 标题: 请教一个密码问题。 还是有问题：
在DBA Studio 中 添加数据库到树中，点连接 输入sys/change_on_install显示 该数据库当前已关闭。要启动该数据库，请作为sysdba重新连接，选择例程下的数据库对象，然后在“数据库”属性工作表的“一般信息”页上将该数据库更改为打开状态。
我按照上面的操作执行。弹出对话框让选择初始化参数文件，我选择默认的<本地init.ora>;开始执行时正在启动数据库时却弹出ORA-01017:无效的用户名/口令；登陆被拒绝。
我找到INIT.ORA文件，文件内容如下：
#
# Copyright (c) 1991, 1998 by Oracle Corporation
#
##############################################################################
# Example INIT.ORA file
#
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
#
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
#
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
#
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
#
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.
#
# INSTRUCTIONS: Edit this file and the other INIT files it calls for
# your site, either by using the values provided here or by providing
# your own. Then place an IFILE= line into each instance-specific
# INIT file that points at this file.
#
# NOTE: Parameter values suggested in this file are based on conservative
# estimates for computer memory availability. You should adjust values upward
# for modern machines.
