当在Linux Shell中运行SQL*Plus的时候，并不提供浏览历史命令行的功能。相反的，在Windows操作系统上，当在DOS命令窗口中运行SQL*Plus的时候，可以使用向上，向下键来跳回之前已经执行过的SQL语句。你可以 根据需要修改他们，然后按[Enter]重新提交执行。
为了在Linux中达到同样的目的，你可以安装rlwrap，这个程式本身是个Shell，可以运行任何你提供给它的命令包括参数，并添加命令历史浏览功能。
1：安装
rlwrap-0.28.tar.gz下载地址:http://utopia.knoware.nl/~hlub/uck/rlwrap/
或http://download.csdn.net/detail/xyz846/4084082
1):解压缩安装文件
[oracle@Channel-MQ3 ~]$gunzip rlwrap-0.28.tar.gz
[oracle@Channel-MQ3 ~]$tar xvf rlwrap-0.28.tar
2):切换到root用户，执行下面的命令
[root@Channel-MQ3 ~]# cd /home/oracle/rlwrap-0.28
[root@Channel-MQ3 rlwrap-0.28]# ls
aclocal.m4 completions configure INSTALL README TODO
AUTHORS config.h configure.ac Makefile src tools
bash30-005.patch config.h.in COPYING Makefile.am stamp-h1
BUGS config.log distribution Makefile.in test
ChangeLog config.status doc NEWS test.log
[root@Channel-MQ3 rlwrap-0.28]#./configure
[root@Channel-MQ3 rlwrap-0.28]#make
[root@Channel-MQ3 rlwrap-0.28]#make install
如果编译的时候出错：
configure: checking for pty ranges...
checking for tgetent... no
checking for tgetent in -lcurses... no
checking for tgetent in -lncurses... yes
checking for readline in -lreadline... no
configure: error:
You need the GNU readline library(ftp://ftp.gnu.org/gnu/readline/ ) to build
this program!
请下载Readline，地址:
http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html
或
http://download.csdn.net/detail/xyz846/4084172
然后./configure & make & make install
如果运行时报错:
rlwrap: error while loading shared libraries: libreadline.so.6: cannot open shared object file:
No such file or directory
你可以在root用户下修改/etc/ld.so.conf，设置so库的load路径
先找到这个libreadline.so.6的路径
find / -name libreadline.so.6
/usr/local/lib/libreadline.so.6
在最后的一行下加上/usr/local/lib就可以了，这里的
/usr/local/lib
加入要重启生效，不过我们也可以执行ldconfig -v即时生效
2:使用
$ rlwrap [-options]
[oracle@Channel-MQ3 ~]$ which rlwrap
/usr/local/bin/rlwrap
[oracle@Channel-MQ3 ~]$ rlwrap sqlplus / as sysdba

另外rlwrap还有很多选项可以设置
eg:
−l, −−logfile file
Append command’s output (including echo’ed user input) to file (creating file when it doesn’t exist).
测试如下
[oracle@Channel-MQ3 ~]$ rlwrap -l benbotest.log sqlplus / as sysdba

当然，如果嫌每次敲rlwrap不爽，可以在/etc/profile或者自己的~/.bash_profile里面添加alias sqlplus='rlwrap sqlplus'。
