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:

2、启动数据库:
连接到sqlplus
sqlplus /nolog
结果如下:

SQL>
以sysdba登陆,并执行命令startup
SQL>conn /as sysdba
Connected to an idle instance.
SQL> startup
结果如下:
ORACLE instance started.

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:
SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 4 15:10:59 2014
Copyright (c) 1982, 2009, Oracle. All rights reserved.
SQL>
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
*
ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 14138
Session ID: 75 Serial number: 503
SQL>
退出sqlplus:
SQL> exit

2、关闭监听:
bash-4.1$ lsnrctl stop // oracle用户下执行
