表空间(上),表空间(
4.直接修改表空间扩容:
(1)一般表空间:
自动扩展: alter database datafile '/oracle/app/oradata/tbs_sys_ptcl.dbf' autoextend on;
关闭自动扩展:alter database datafile '/oracle/app/oradata/tbs_sys_ptcl.dbf' autoextend off;
指定大小: alter database datafile '/oracle/app/oradata/tbs_sys_ptcl.dbf' resize 50m;
(2)临时表空间
自动扩展: alter database tempfile '/oracle/app/oradata/tbs_temp_ptcl.dbf' autoextend on;
关闭自动扩展:alter database datafile '/oracle/app/oradata/tbs_sys_ptcl.dbf' autoextend off;
指定大小: alter database tempfile '/oracle/app/oradata/tbs_temp_ptcl.dbf' resize 50m;
(3)扩容后查找语句:
select * from dba_tablespaces a where a.tablespace_name like '%PTCL';
5.为表空间添加新的数据文件
(1)一般表空间:
指定大小: alter tablespace tbs_sys_ptcl add datafile '/oracle/oradata/ora242/YM_tbs/tbs_sys_ptcl.ora' size 50M ;
自动扩展 alter tablespace tbs_sys_ptcl add datafile '/oracle/oradata/ora242/YM_tbs/tbs_sys_ptcl.ora' size 50M
autoextend on;
(2)临时表空间
指定大小:alter tablespace tbs_temp_ptcl add tempfile '/oracle/oradata/ora242/YM_tbs/tbs_temp_ptcl.dbf' size 50M;
自动扩展:alter tablespace tbs_temp_ptcl add tempfile '/oracle/oradata/ora242/YM_tbs/tbs_temp_ptcl.dbf' size 50M
autoextend on;
6. 删出用户及其表空间:
(1)删掉用户:
drop user lbi_sys_ptcl cascade;
(2)删掉表空间:
drop tablespace TBS_SYS_PTCL including contents and datafiles CASCADE CONSTRAINTS ;
(3)删掉数据文件:
alter database datafile '/oracle/oradata/ora242/YM_tbs/TBS_DW_YM.ora' offline drop;
1、用sys用户登录,先创建表空间,再创建用户,用户要建在表空间上;
例:CREATE TABLESPACE "CC_HINDEX"
---- DATAFILE 'F:\oracle\product\10.2.0\oradata\数据库名\CC_HINDEX.ora' SIZE 300M
AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED
ONLINE
PERMANENT
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
BLOCKSIZE 8K
SEGMENT SPACE MANAGEMENT AUTO
FLASHBACK ON;
-----create user XXX
identified by XXX
quota unlimited on cc_hindex
-- Grant/Revoke role privileges
grant connect to xxx;
grant resource to xxx;
grant dba to xxx;
-- Grant/Revoke system privileges
grant alter session to xxx;
希望对你的帮助,以前我走过这样的误区。
select table_name ,tablespace_name from dba_tables where tablespace_name = '表空间名';
需要DBA权限
select table_name ,tablespace_name from user_tables where tablespace_name = '表空间名';
只查当前用户的不需DBA权限
