sqlplus -v 为空

安装rac集群，安装oracle软件，安装完成，验证，sqlplus -v不出现，那肯定是环境变量的问题。 ：-bash: rlwrap: command not found， su - oracle[oracle@db1 ~]$ vi .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then         . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH export PS1 umask 022 alias sqlplus="rlwrap sqlplus" export TMP=/tmp export export TMPDIR=$TMP export ORACLE_HOSTNAME=db1 ORACLE_SID=orcl1; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM ORACLE_BASE=/oracle; export ORACLE_BASE ORACLE_HOME=/oracle/home; export ORACLE_HOME NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH THREADS_FLAG=native; export THREADS_FLAG ".bash_profile" 27L, 627C 百度前辈们，给出建议，要安装rlwrap工具可以解决，但是我没有解决 https://www.cnblogs.com/xuzhiwei/p/3700051.html 就直接修改环境变量，把它注掉 [oracle@db1 ~]$ vi .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then         . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH export PS1 umask 022 #alias sqlplus="rlwrap sqlplus" export TMP=/tmp export export TMPDIR=$TMP export ORACLE_HOSTNAME=db1 ORACLE_SID=orcl1; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM ORACLE_BASE=/oracle; export ORACLE_BASE ORACLE_HOME=/oracle/home; export ORACLE_HOME NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH THREADS_FLAG=native; export THREADS_FLAG ".bash_profile" 27L, 627C source .bash__profile l另外打开一个会话，验证[oracle@db1 ~]$ sqlplus -v SQL*Plus: Release 11.2.0.4.0 Production
