注：因为一般特殊字符可以使用双引号处理，但是如果密码中含有双引号，就不能用双引号处理，可以直接使用password修改密码。

2.4  本文结论

参考下表：


Linux平台
sqlplus工具
数据泵工具（exp、expdp）

普通用户
无tns
sqlplus ‘lhr/"[email protected]\r/0"‘
expdp ‘lhr/"[email protected]\r/0"‘

有tns
sqlplus ‘lhr/"[email protected]\r/0"‘@LHRDB
expdp ‘lhr/"[email protected]\r/0"‘@LHRDB

sys用户
无tns
sqlplus / as sysdba

有tns
sqlplus ‘sys/"[email protected]\r/0"‘@LHRDB as sysdba
expdp \‘‘sys/"[email protected]\r/0"‘@LHRDB as sysdba\‘

正常密码
sqlplus sys/[email protected] as sysdba
expdp \‘sys/[email protected] as sysdba\‘

备注：含特殊字符密码为：[email protected]\r/0，正常密码为：lhr，tns为：LHRDB，总的原则为：密码用双引号括起来，用户名和密码用单引号括起来，然后【用户名】+【密码】+【tns】+【as sysdba】用单引号括起来，最后的这个单引号用\进行转义

alter user lhr identified by "[email protected]\r/0";

sqlplus sys/[email protected] as sysdba
expdp \"sys/[email protected] as sysdba\"

备注：含特殊字符密码为：[email protected]\r/0，正常密码为：lhr，tns为：LHRDB，总的原则为：密码用3个双引号括起来，或者用一个双引号括起来，然后用\将双引号进行转义   DIRECTORY=DATA_PUMP_DIR DUMPFILE=dmp_SCOTT.dmp SCHEMAS=SCOTT  reuse_dumpfiles=y

【方法】Oracle用户密码含特殊字符时的登陆问题的相关文章

Oracle用户密码含有特殊字符应当如何处理

通常我们在设置Oracle密码时会将密码设置的比较复杂,一般有字母数字特殊符号组成但是在有特殊符号时,修改密码或着导入导出数据时会遇到麻烦,下文便是对该情况下的解释说明:本文以特殊符号"/"作为例子一.Linux环境,数据库为Oracle10g1.修改密码 [[email protected] oracle]$ sqlplus '/as sysdba' SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 17 14:33:32 20

sqlplus连接oracle数据库--密码含特殊字符

sqlplus a/password! 登录不进数据库,下面显示的密码不是password! 然后用sqlplus  /nolog;conn a/password!可以正常连接,说明用户名和密码没问题 后来想是不是!特殊符号的问题: 尝试: sqlplus "a/password!" 还是不行,没辙了啊,什么鬼 sqlplus 'a/password!'  竟然OK了. 只能说自己基础不好吧~ 原文地址:https://www.cnblogs.com/cnmarkao/p/124249

Oracle用户密码过期和用户被锁解决方法

[原因/触发因素] 确定是由于oracle11g中默认在default概要文件中设置了"PASSWORD_LIFE_TIME=180天"所导致. [影响和风险] 影响    密码过期后,业务进程连接数据库异常,影响业务使用.    问题发生频率    数据库密码过期后,业务进程一旦重启会提示连接失败. [解决方案] 按照如下步骤进行操作: 1.查看用户的proifle是哪个,一般是default: sql>SELECT username,PROFILE FROM dba_user

oracle用户密码有@符号连接方法

oracle用户密码不小心设置了带有"@"符号,正常登陆总是无法登陆,提示无法解析的连接字符串错误,其实解决办法很简单,转义即可,示例如下: exp system/\"[email protected]\"@localhost:1521/orcl conn system/\"[email protected]\"@localhost:1521/orcl

Oracle用户密码过期问题解决

一.用户密码即将过期,导致autotrace无法打开           如果用户密码即将过期,在登录数据库时会收到如下提示:           ERROR:            ORA-28002: the password will expire within 7 days           当然,此时密码还未真正过期,用户在收到错误提示后依然可以登录数据库.但是,如果当收到密码即将过期的提示,想要开启autotrace就会有问题. SQL> conn darren/darren ER

oracle 用户密码原则

今天在oracle数据库中修改用户密码的时候发现了一个下面的规律 1  密码只由字母组成,创建成功 SQL> alter user ics identified by password; User changed. 2 密码只由数字组成,创建成功 SQL> alter user ics identified by 123456; User changed. 3 密码由字母+数字组成,创建成功 SQL> alter user ics identified by password123; U

技巧：如何提升Oracle用户密码的安全性

环境:Oracle 11.2.0.4 客户需求:主要背景是数据库中有很多业务用户名,且由于部分用户缺乏安全意识,甚至直接将自己的密码设置为和用户名一样,目前客户期望密码设置不要过于简单,最起码别和用户名一致或相似就好. 1.官方解决方案 2.删减版解决方案 3.测试验证方案 4.用户最近一次的登录时间 1.官方解决方案 实际上Oracle提供有一个非常好用的安全校验函数,来提升用户密码的复杂性.这个在之前的文章<Oracle 11g 安全加固>中的"1.8.数据库密码安全性校验函数&

Oracle用户密码过期的处理方法

受影响版本:Oracle11g以上版本. 导致密码消失的原因:Oracle 11g中默认的DEFAULT概要文件中口令有效期PASSWORD_LIFE_TIME默认值为180天. 当以客户端登陆Oracle提示ORA-28002,则基本可以确定登陆帐号已过有效期,使用具有DBA权限的帐号重置该帐号密码即可. 解决方法: 以下步骤以具有DBA权限用户操作 1.查看口令失效用户的profile文件 SQL>SELECT username,profile FROM dba_users; EM:服务器>
