建立表空間:
建立common使用者:- 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
autoextend on next 20m maxsize unlimited;
- create tablespace user_data datafile
autoextend on next 40m maxsize unlimited;
- create tablespace user_index logging datafile
autoextend on next 32m maxsize 2048m extent management local;
create user c##amap identified by amap default tablespace user_data temporary tablespace user_temp ;
建立local使用者:
create user amap identified by amap default tablespace user_data temporary tablespace user_temp;
使用者授權:
匯入命令- grant dba to amap;
- grant connect to amap;
- grant resource to amap;
- grant unlimited tablespace to amap;
imp amap/amap@amap file=/opt/oracle/0430.dmp full=y
檢視當前例項:
select status,instance_name from v$instance;
oracle 多個例項互相切換例項
windows中設定環境變數
set oracle_sid=a
linux中設定環境變數
export oracle_sid=a
//啟動sqlplus
sqlplus / as sysdba
1.登入伺服器,切換到oracle使用者,或者以oracle使用者登入
[admin@dataserver ~]$ su - oracle
密碼:
[oracle@dataserver ~]$
2.開啟監聽服務
[oracle@localhost ~]$ lsnrctl start
可以通過lsnrctl status命令檢視oracle***執行狀況
[oracle@localhost ~]$ lsnrctl status
3.以sys使用者身份登入oracle
複製**
[oracle@localhost ~]$ sqlplus /nolog
sql*plus: release 11.2.0.1.0 production on fri dec 1 23:29:19 2017
sql> conn /as sysdba
connected to an idle instance.切換使用者:
conn 使用者名稱/密碼 [as sysdba],如果是sys使用者一定要寫上as sysdba
4.通過startup命令啟動例項
sql> startup
oracle instance started.二、linux下關閉oracletotal system … … database mounted. database opened.
1.關閉資料庫例項
sql> shutdown
database closed. database dismounted. oracle instance shut down.
sql> quit
2.關閉***
[oracle@localhost ~]$ lsnrctl stop
