#added for oracle
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=/oracle/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=pxxerxxs
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=$PATH:$ORACLE_HOME/bin
[oracle@localhost root]$
配置里面有值，问题在哪里？
8，su的时候有差异
不加-的话的话只是切换用户 不去更换用户的配置，加上-后 再去sqlplus 试试
[oracle@localhost ~]$ exit
logout
[root@localhost ~]# su oracle
[oracle@localhost root]$ echo $ORACLE_BASE
[oracle@localhost root]$ exit
exit
[root@localhost ~]# su - oracle
[oracle@localhost ~]$ echo $ORACLE_BASE
/oracle/app/oracle
[oracle@localhost ~]$
9，验证下su - oracle
[oracle@localhost ~]$ rlwrap sqlplus "/ as sysdba"
rlwrap: warning: your $TERM is 'xterm' but rlwrap couldn't find it in the terminfo database. Expect some problems.

[oracle@localhost ~]$ tnsping pxxerxxs
