SQL*PLUS 命令的History功能

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键重新提交执行.
然而,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.
为了在Linux中达到同样的目的,你可以使用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,有命令历史浏览功能.

 

环境：

OS:Oracle-Enterprise-R5-U2-Server-i386 Oracle:linux_x86_11gR1_database

一:安装readline
OS的安装光盘里提供了readline包.

[root@oracle11g ~]# rpm -Uvh readline*

error: Failed dependencies: libtermcap-devel is needed by readline-devel-5.1-1.1.i386.rpm
[root@oracle11g ~]# rpm -Uvh libtermcap-devel-2.0.8-46.1.i386.rpm

[root@oracle11g ~]# rpm -Uvh readline*

package readline-5.1-1.1 is already installed
[root@oracle11g ~]

二:安装rlwrap

Download：

[root@oracle11g ~]# tar -zxvf rlwrap-0.30.tar.gz

[root@oracle11g ~]# cd rlwrap-0.30

[root@oracle11g rlwrap-0.30]# ./configure

[root@oracle11g rlwrap-0.30]# make

[root@oracle11g rlwrap-0.30]# make install

[root@oracle11g rlwrap-0.30]# rlwrap
