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：

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/"l@hr"'@LHRDB as sysdba\' DIRECTORY=DATA_PUMP_DIR DUMPFILE=SCOTT%U.dmp SCHEMAS=SCOTT COMPRESSION=all metrics=y |

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'\ 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 | |||
