[db2]数据库管理
前言
- db2版本:10.5
- 实例所有者:db2inst1
- 待新建数据库:ticm,授权用户:ticm/123456。(用户是系统用户)
创建数据库
- 建库
# create database ticm: 创建名为ticm的数据库
# automatic storage yes: 自动存储器
# on '/home/ticm' dbpath on '/home/ticm': 存储路径和数据库路径
# using codeset gbk territory cn: 使用gbk编码,地域为中国。(也可以使用UTF-8编码)
# collate using system: 排序类型。system表示以系统代码集排序
# pagesize 16384: 默认页大小为16KB
db2 create database ticm automatic storage yes on '/home/ticm' dbpath on '/home/ticm' using codeset gbk territory cn collate using system pagesize 16384
- 查看数据库信息:
db2 list db directory
- 连接数据库测试
db2 connect to ticm user ticm using 123456
- 使用db2inst1用户进行授权
db2 terminate
db2 connect to ticm
db2 grant dbadm on database to user ticm
- 创建表空间
# 使用db2instl1连接数据库
db2 connect to ticm user db2inst1 using 123456
# 查看表空间(一般会自动创建四个)
db2 list tablespaces
# 创建缓冲池
db2 create bufferpool ticm_pool size 8000 pagesize 32k
# 创建表空间:TICM_DATA_TBS、 TICM_IDX_TBS和TICM_TEMP
db2 create large tablespace TICM_DATA_TBS pagesize 32k managed by automatic storage extentsize 32 overhead 10.5 prefetchsize 32 transferrate 0.14 bufferpool ticm_pool
db2 create regular tablespace TICM_IDX_TBS pagesize 32k managed by automatic storage extentsize 32 overhead 10.5 prefetchsize 32 transferrate 0.14 bufferpool ticm_pool
db2 create user temporary tablespace TICM_TEMP pagesize 32k managed by automatic storage extentsize 32 overhead 10.5 prefetchsize 32 transferrate 0.14 bufferpool ticm_pool
# 为表空间赋权
db2 grant use of tablespace TICM_DATA_TBS TO user ticm with grant option
db2 grant use of tablespace TICM_IDX_TBS TO user ticm with grant option
db2 grant use of tablespace TICM_TEMP TO user ticm with grant option
删除数据库
# 一般步骤。注意修改数据库名
db2 terminate
db2 drop db dbname
# 强删。注意修改数据库名
db2 force application all; db2 terminate; db2 drop db dbname
