1 成立表空间

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

2 成立用户

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 参数改正

ALTER SYSTEM SET sga_target = 1000M SCOPE=SPFILE;
ALTER SYSTEM SET pga_aggregate_target = 200M SCOPE=SPFILE;
ALTER SYSTEM SET OPEN_CURSORS=500 SCOPE=SPFILE;
ALTER SYSTEM SET processes=200 SCOPE=SPFILE;
ALTER SYSTEM SET remote_login_passwordfile = NONE
SCOPE=SPFILE;
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 查看表空间的利用情形

select sum(bytes)/(1024*1024) as free_space,tablespace_name 　　from dba_free_space 　　group 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、查看掌握文件

select name from v$controlfile;

9、查看日记文件

select member from v$logfile;

10 .完毕用户会话

alter system kill session 'SID,SERIAL#'; select sid,serial#,username,program,machine,status from v$session;
