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：

[[email protected] admin]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Fri Feb 24 09:25:35 2017

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, Automatic Storage Management, OLAP, Data Mining

and Real Application Testing options

[email protected]> alter user lhr identified by "[email protected]";

User altered.

[email protected]> exit

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

expdp \‘‘sys/"[email protected]"‘@LHRDB as sysdba\‘ DIRECTORY=DATA_PUMP_DIR DUMPFILE=SCOTT%U.dmp SCHEMAS=SCOTT COMPRESSION=all metrics=y

[[email protected] admin]$ expdp \‘‘sys/"[email protected]"‘@LHRDB as sysdba\‘ DIRECTORY=DATA_PUMP_DIR DUMPFILE=SCOTT%U.dmp SCHEMAS=SCOTT COMPRESSION=all metrics=y

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"‘
普通用户	有tns	sqlplus ‘lhr/"[email protected]\r/0"‘@LHRDB	expdp ‘lhr/"[email protected]\r/0"‘@LHRDB
sys用户	无tns	sqlplus / as sysdba	expdp \‘/ 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"; alter user sys identified by "[email protected]\r/0"; set define off alter user scott identified by "$tiger&[email protected]\r/0%s,d$"; alter user scott identified by "$?`$%*H\@f‘\<a-q [email protected]#<="">`}:H$"; password scott

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