一、启动监听与数据库
1、启动监听：
- [root@JTWF oracle]# su - oracle
- bash-4.1$ 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：
- LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 04-APR-2014 16:15:25

- Starting /home/oracle/product/11.2/db_1/bin/tnslsnr: please wait...
- TNSLSNR for Linux: Version 11.2.0.1.0 - Production
- System parameter file is /home/oracle/product/11.2/db_1/network/admin/listener.ora
- Log messages written to /home/oracle/diag/tnslsnr/JTWF/listener/alert/log.xml
- Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=JTWF)(PORT=1521)))
- Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=JTWF)(PORT=1521)))
- STATUS of the LISTENER

- (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=JTWF)(PORT=1521)))
- The listener supports no services
- The command completed successfully
2、启动数据库：
连接到sqlplus
- su oracle
- bash-4.1$ sqlplus /nolog
结果如下：
- SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 4 16:15:52 2014
- Copyright (c) 1982, 2009, Oracle. All rights reserved.
- 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
- Fixed Size 2217992 bytes
- Variable Size 578815992 bytes
- Database Buffers 251658240 bytes
- Redo Buffers 6590464 bytes
- Database mounted.
- Database opened.
- SQL>
二、关闭数据库、监听
1、关闭数据库
- su - oracle
- [root@JTWF oracle]# su oracle
- bash-4.1$ sqlplus /nolog
登陆sqlplus，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
- LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 04-APR-2014 15:17:00
- Copyright (c) 1991, 2009, Oracle. All rights reserved.
