oracle資料庫表空間的建立與使用

以下操作請使用sys系統賬號操作！

1. 查詢物理儲存的位置

select tablespace_name,

file_id,
file_name,
round(bytes / (1024 * 1024), 0) total_space
from dba_data_files
order by tablespace_name;

2. 建立使用者的臨時表空間

臨時表空間用於使用者執行查詢時要使用的快取空間。

檔案路徑儲存在/opt/oracle/oradata/biee目錄

create temporary tablespace dw_test_tmp_tbs

tempfile '/opt/oracle/oradata/biee/dw_test_tmp_tbs01.dbf'
size 32m
autoextend on
next 32m maxsize 2048m
extent management local;

這裡要指定初始代銷，自增的大小，以及檔案的最大值。

create tablespace dw_test_tbs

logging
datafile  '/opt/oracle/oradata/biee/dw_test_tbs01.dbf'
size 7167m
autoextend on
next 3072m maxsize 32767m
autoallocate             
extent management local 
segment space management auto;

create user dw_test identified by "dw_test" default tablespace dw_test_tbs  temporary tablespace dw_test_tmp_tbs profile default;

grant

create session, create any table, create any view ,create any index, create any procedure,
alter any table, alter any procedure,
drop any table, drop any view, drop any index, drop any procedure,
select any table, insert any table, update any table, delete any table,
select any sequence, create any sequence,drop any sequence，create trigger
to dw_test;
alter user dw_test quota unlimited on dw_test_tbs;

為了減少運維麻煩，通常在初始建立時建立多個表空間檔案，這樣可以維持使用很久。

因此，我通常每次都是增加10-20個檔案來使用，注意每個檔案後面的序號連續。

alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs02.dbf' size 7167m autoextend on next 3072m maxsize 32767m;

alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs03.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs04.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs05.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs06.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs07.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs08.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs09.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
alter tablespace dw_test_tbs add datafile '/opt/oracle/oradata/biee/dw_test_tbs010.dbf' size 7167m autoextend on next 3072m maxsize 32767m;
