-------------------------------------------------------------------------

第二章 实验部分

2.1 实验环境介绍

项目source db
db 类型RAC
db version11.2.0.3.0
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：

2.3.2 expdp连接

密码用双引号，用户名和密码用单引号括起来，然后【用户名】+【密码】+【tn】+【as sysdba】用单引号括起来，最后的这个单引号用\进行转义

2.3.3 修改密码中含有“@”符号

[oracle@orcltest ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.3.0 Production on Thu Mar 16 17:10:26 2017 Copyright (c) 1982, 2011, Oracle. All rights reserved.

2.3.4 修改密码中含有双引号符号

修改scott用户的密码为：a"b
[oracle@orcltest ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.3.0 Production on Thu Mar 16 17:39:18 2017 Copyright (c) 1982, 2011, Oracle. All rights reserved.

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tnssqlplus 'lhr/"l@h\r/0"'expdp 'lhr/"l@h\r/0"'
有tnssqlplus 'lhr/"l@h\r/0"'@LHRDBexpdp 'lhr/"l@h\r/0"'@LHRDB
sys用户无tnssqlplus / as sysdbaexpdp \'/ AS SYSDBA\'
有tnssqlplus 'sys/"l@h\r/0"'@LHRDB as sysdbaexpdp \''sys/"l@h\r/0"'@LHRDB as sysdba\'
正常密码sqlplus sys/lhr@lhrdb as sysdbaexpdp \'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 offalter user scott identified by "$tiger&123l@h\r/0%s,d$";alter user scott identified by "$?`$%*H\@f'\<a-q $-@#<="">`}:H$";password scott

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
