su - oracle 切换到oracle账户
lsnrctl start 启动监听
sqlplus /nolog 登陆sqlplus
conn /as sysdba 或者 sqlplus / as sysdba sysdba登陆到本机的数据库
startup 启动数据
shutdown immediate 关闭数据库
lsnrctl stop 关闭监听
一、启动监听与数据库
1、启动监听：
su - oracle
lsnrctl start
说明：
su后面追加 -，-l,--login，表示切换用户时，使环境变量(home，shell，user，logname，path等）和欲切换的用户相同、
结果如下，则启动成功：

以sysdba登陆，并执行命令startup
SQL>conn /as sysdba
Connected to an idle instance.

二、关闭数据库、监听
1、关闭数据库
使用oracle账号登陆sqlplus，
su - oracle
sqlplus /nolog
结果如下：

sysdba登陆：
SQL>conn /as sysdba
Connected.
关闭数据库：
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
关闭数据库后，若执行查询命令， 则会报如下错误：
SQL> select * from vio_business_request;
select * from vio_business_request
*

退出sqlplus：
SQL> exit
