Oracle10G常用维护语句汇总

1 创建表空间

CREATE TABLESPACE CPORTAL LOGGING DATAFILE '/dev/raw/raw1' SIZE 30000M REUSE EXTENT MANAGEMENT LOCAL

2 创建用户

CREATE USER CPORTAL PROFILE DEFAULT IDENTIFIED BY CPORTAL DEFAULT

TABLESPACE CPORTAL TEMPORARY TABLESPACE TEMP ACCOUNT UNLOCK;

GRANT CONNECT TO CPORTAL;

GRANT RESOURCE TO CPORTAL;

3 参数修改

ALTER SYSTEM SET sga_target 1000M SCOPESPFILE;

ALTER SYSTEM SET pga_aggregate_target 200M SCOPESPFILE;

ALTER SYSTEM SET OPEN_CURSORS500 SCOPESPFILE;

ALTER SYSTEM SET processes200 SCOPESPFILE;

ALTER SYSTEM SET remote_login_passwordfile NONE

SCOPESPFILE;

create pfile from spfile;

-- Modify the other oracle parameter！

ALTER DATABASE TEMPFILE '/opt/oracle/oradata/cportal/temp01.dbf' RESIZE 1024M;

ALTER DATABASE DATAFILE '/opt/oracle/oradata/cportal/undotbs01.dbf' RESIZE 1024M;

ALTER DATABASE DATAFILE '/opt/oracle/oradata/cportal/undotbs01.dbf' AUTOEXTEND ON MAXSIZE 10240M

4 查看表空间名称和大小

select t.tablespace_name,round(sum(bytes/(1024*1024)),0) ts_size from dba_tablespaces t dba_data_files d

where t.tablespace_name = d.tablespace_name

group by t.tablespace_name;

5 查看表空间的使用情况

select sum(bytes)/(1024*1024)as free_space,tablespace_name from dba_free_spacegroup by tablespace_name;

 

6、查看表空间物理文件的名称及大小

select tablespace_name,file_id,file_name,

round(bytes/(1024*1024),0) total_space

from dba_data_files

order by tablespace_name;

7、查看数据库库对象

select owner,object_type,status,count(*)count# from all_objects group by owner,object_type，status;

8、查看控制文件

select name from v$controlfile;

9、查看日志文件

select member from v$logfile;

10 、结束用户会话

alter system kill session 'SID,SERIAL#';

select sid,serial#,username,program,machine,status from v$session;
