linux下oracle11g R2的启动与关闭监听、数据库

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.
Total System Global Area 839282688 bytes

Variable Size 578815992 bytes
Database Buffers 251658240 bytes

Database mounted.
Database opened.
SQL>

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
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

2、关闭监听:

bash-4.1$ lsnrctl stop // oracle用户下执行
