rlwrap安装之后无法使用

安装完rlwrap软件包之后，修改sqlplus命令的别名

[oracle@up ~]$ vim .bashrc

alias sqlplus='rlwrap sqlplus'

alias sql='rlwrap sqlplus'

alias lsnrctl='rlwrap lsnrctl'

alias rman='rlwrap rman'

登录数据库无法登录

[oracle@up ~]$ sqlplus / as sysdba

rlwrap: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory

没有找到libreadline.so.5库，需安装libreadline.so.5

安装库文件

[root@up Packages]# yum install compat-readline5 -y

安装之后再登录数据库

[oracle@up ~]$ sqlplus / as sysdba

rlwrap: error while loading shared libraries: libtermcap.so.2: cannot open shared object file: No such file or directory

缺少libtermcap.so.2库，安装compat-libtermcap包：

[root@up Packages]# yum install compat-libtermcap -y

安装完之后，再次登录

[root@up Packages]# su - oracle

[oracle@up ~]$ sqlplus / as sysdba
