linux下sqlplus怎么使用上下键和回退

1.配置yum源：

[oracle@saperp ~]$ cat /etc/yum.repos.d/CentOS-Debuginfo.repo 
# CentOS-Debug.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#

# All debug packages from all the various CentOS-7 releases
# are merged into a single repo, split by BaseArch
#
# Note: packages in the debuginfo repo are currently not signed
#

[base-debuginfo]
name=CentOS-7 - Debuginfo
baseurl=http://debuginfo.centos.org/7/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-7
enabled=1
#

2.安装rlwarp

[root@saperp ~]# yum install rlwrap*

3.oracle环境变量添加:

[oracle@saperp ~]$ pwd
/home/oracle

[oracle@saperp ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
