1.創建數據庫
[db2inst2@xifenfei ~]$ db2 “create database xifenfei automatic storage yes
on /home/db2inst2/dbauto dbpath on /home/db2inst2/xifenfei
using codeset utf-8 territory cn collate using system”
DB20000I The CREATE DATABASE command completed successfully.
DBPATH ON表示數據庫目錄
USING CONDESET codeset TERRITORY territory指定數據庫編碼集(Codeset)和區域(Territory)
automatic storage yes on /home/db2inst2/dbauto 表示啓用自動存儲管理，on指定路徑
2.查看數據庫
[db2inst2@xifenfei ~]$ db2 list db directory
System Database Directory
Number of entries in the directory = 1
Database 1 entry:
Database alias = XIFENFEI
Database name = XIFENFEI
Local database directory = /home/db2inst2/xifenfei
Database release level = c.00
Comment =
Directory entry type = Indirect
Catalog database partition number = 0
Alternate server hostname =
Alternate server port number =
3.連接數據庫
[db2inst2@xifenfei ~]$ db2 connect to xifenfei
Database Connection Information
Database server = DB2/LINUX 9.5.0
SQL authorization ID = DB2INST2
Local database alias = XIFENFEI
4.創建緩衝池
[db2inst2@xifenfei ~]$ db2 “create bufferpool bp32k size 100 pagesize 32k”
DB20000I The SQL command completed successfully.
DB2默認創建庫指創建4k的bufferpool，因爲下面需要創建32k的表空間，所以需要先創建32k的bufferpool
5.創建數據庫管理(DMS)的數據表空間
[db2inst2@xifenfei ~]$ db2 “create large tablespace tbs_data pagesize 32k managed by database
using (file ‘/home/db2inst2/dms/tbs_data01.dbf’ 100M) extentsize 32 prefetchsize automatic
bufferpool bp32k no file system caching”
DB20000I The SQL command completed successfully.
no file system caching關閉文件系統緩存,默認選項
6.創建系統管理(SMS)的臨時表空間
[db2inst2@xifenfei ~]$ db2 “create temporary tablespace tbs_temp pagesize 32k
managed by system using (‘/home/db2inst2/xifenfei/temp’) bufferpool bp32k”
DB20000I The SQL command completed successfully.
7.創建系統管理(SMS)的用戶臨時表空間
[db2inst2@xifenfei ~]$ db2 “create user temporary tablespace tbs_user_temp pagesize 32k
managed by system using (‘/home/db2inst2/xifenfei/user_temp’) bufferpool bp32k”
DB20000I The SQL command completed successfully.
8.自動存儲管理(Automatic Storage)的表空間
[db2inst2@xifenfei ~] db2 “create tablespace tbs_data2 initialsize 10M increasesize 10M maxsize 10G”
DB20000I The SQL command completed successfully.
數據表空間選擇DMS,臨時表空間選擇SMS
9.查看錶空間狀態
[db2inst2@xifenfei ~]$ db2 list tablespaces show detail
