1，oracle登录报错 [oracle@localhost root]$ rlwrap sqlplus "/ as sysdba" Error 6 initializing SQL*Plus SP2-0667: Message file sp1<lang>.msb not found SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory [oracle@localhost root]$ [oracle@localhost root]$
4，ORACLE_HOME环境变量有值了，再去用sqlplus登录一下，试试看 [oracle@localhost root]$ rlwrap sqlplus "/ as sysdba" rlwrap: warning: your $TERM is ‘xterm‘ but rlwrap couldn‘t find it in the terminfo database. Expect some problems. rlwrap: Cannot execute sqlplus: Permission denied [oracle@localhost root]$
[oracle@localhost root]$ exit exit [root@localhost ~]# vim /etc/profile [root@localhost ~]# source /etc/profile [root@localhost ~]# su oracle [oracle@localhost root]$ rlwrap sqlplus "/ as sysdba" rlwrap: warning: your $TERM is ‘xterm‘ but rlwrap couldn‘t find it in the terminfo database.
