oracle 常用命令操作

创建表空间：

- drop tablespace user_temp including contents and datafiles; - drop tablespace user_data including contents and datafiles; - drop tablespace user_index including contents and datafiles; - drop user C##AMAP cascade; - drop user amap cascade; - create temporary tablespace user_temp tempfile '/u01/app/oracle/oradata/orcl/amap/amap_temp.dbf' size 2G reuse autoextend on next 20m maxsize unlimited; - create tablespace user_data datafile '/u01/app/oracle/oradata/orcl/amap/amap.dbf' size 100M reuse autoextend on next 40M maxsize unlimited; - create tablespace user_index logging datafile '/u01/app/oracle/oradata/orcl/amap/amap_index.dbf' size 100m autoextend on next 32m maxsize 2048m extent management local;

创建common用户：

create user c##amap identified by amap default tablespace user_data temporary tablespace user_temp ;

创建local用户：

create user amap identified by amap default tablespace user_data temporary tablespace user_temp;

用户授权：

- grant dba to amap; - grant connect to amap; - grant resource to amap; - grant unlimited tablespace to amap;

导入命令

imp amap/amap@amap file=/opt/oracle/0430.dmp full=y

查看当前实例：

select status,instance_name from v$instance;

oracle 多个实例互相切换实例

windows中设置环境变量

set ORACLE_SID=a

linux中设置环境变量

export ORACLE_SID=a

//启动sqlplus

sqlplus / as sysdba

1.登录服务器，切换到oracle用户，或者以oracle用户登录

[admin@dataserver ~]$ su - oracle

密码：

[oracle@dataserver ~]$

2.打开监听服务

[oracle@localhost ~]$ lsnrctl start

可以通过lsnrctl status命令查看Oracle监听器运行状况

[oracle@localhost ~]$ lsnrctl status

3.以SYS用户身份登录Oracle

复制代码

[oracle@localhost ~]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Fri Dec 1 23:29:19 2017

Copyright (c) 1982, 2009, Oracle. All rights reserved.

SQL> conn /as sysdba

Connected to an idle instance.

切换用户：

CONN 用户名/密码 [AS SYSDBA]，如果是sys用户一定要写上AS　SYSDBA

4.通过startup命令启动实例

SQL> startup

ORACLE instance started.

Total System … … Database mounted. Database opened.

二、Linux下关闭Oracle

1.关闭数据库实例

SQL> shutdown

Database closed. Database dismounted. ORACLE instance shut down.

SQL> quit

Disconnected from Oracle Database 11g Enterprise Edition Release11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options

2.关闭监听器

[oracle@localhost ~]$ lsnrctl stop
