第二章 实验部分

2.1  实验环境介绍

项目

source db

db 类型

RAC

db version

11.2.0.3.0

db 存储

ASM

OS版本及kernel版本

RHEL 6.5

2.2  实验目标

当用户密码含有特殊字符的时候，测试sqlplus和exp、imp及expdp、impdp的登陆及修改密码问题。

2.3  实验过程

2.3.1  sqlplus连接

普通用户连接：

[oracle@orcltest admin]$ sqlplus / as sysdba

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：

wps494E.tmp

 

Linux平台

sqlplus工具

数据泵工具（exp、expdp）

普通用户

无tns

sqlplus 'lhr/"l@h\r/0"'

expdp 'lhr/"l@h\r/0"'

有tns

sqlplus 'lhr/"l@h\r/0"'@LHRDB

expdp 'lhr/"l@h\r/0"'@LHRDB 

sys用户

无tns

sqlplus / as sysdba

expdp \'/ AS SYSDBA\'

有tns

sqlplus 'sys/"l@h\r/0"'@LHRDB as sysdba

expdp \''sys/"l@h\r/0"'@LHRDB as sysdba\'

正常密码

sqlplus sys/lhr@lhrdb as sysdba

expdp \'sys/lhr@LHRDB as sysdba\'

备注：含特殊字符密码为：l@h\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 "l@h\r/0";

alter user sys identified by "l@h\r/0";

set define off

alter user scott identified by "$tiger&123l@h\r/0%s,d$";

alter user scott identified by "$?`$%*H\@f'\`}:H$";

password scott

 

 

 

 

 

 

 

 

Windows平台

sqlplus工具

数据泵工具（exp、expdp）

普通用户

无tns

sqlplus lhr/"""l@h\r/0"""

sqlplus lhr/\"l@h\r/0\"

expdp lhr/"""l@h\r/0"""

expdp lhr/\"l@h\r/0\"

有tns

sqlplus lhr/"""l@h\r/0"""@LHRDB

sqlplus lhr/\"l@h\r/0\"@LHRDB

expdp lhr/"""l@h\r/0"""@LHRDB

expdp lhr/\"l@h\r/0\"@LHRDB

sys用户

无tns

sqlplus / as sysdba

expdp \"/ as sysdba\"

有tns

sqlplus sys/"""l@h\r/0"""@LHRDB as sysdba

sqlplus sys/\"l@h\r/0\"@LHRDB as sysdba

 

正常密码

sqlplus sys/lhr@lhrdb as sysdba

expdp \"sys/lhr@LHRDB as sysdba\"

备注：含特殊字符密码为：l@h\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
