1．启动数据库
DB2start
2．停止数据库
DB2stop
DB2数据库在linux相关指令之3．连接数据库
DB2 connect to o_yd user DB2 using pwd
4．读数据库管理程序配置
DB2 get dbm cfg
5．写数据库管理程序配置
DB2 update dbm cfg using 参数名 参数值
6．读数据库的配置
DB2 connect to o_yd user DB2 using pwd
DB2 get db cfg for o_yd
7．写数据库的配置
DB2 connect to o_yd user DB2 using pwd
DB2 update db cfg for o_yd using 参数名 参数值
8．关闭所有应用连接
DB2 force application all
DB2 force application ID1,ID2,,,Idn MODE ASYNC
(DB2 list application for db o_yd show detail)
9．备份数据库
DB2 force application all
DB2 backup db o_yd to d:
(DB2 initialize tape on \.tape0)
(DB2 rewind tape on \.tape0)
DB2 backup db o_yd to \.tape0
10．恢复数据库
DB2 restore db o_yd from d: to d:
DB2 restore db o_yd from \.tape0 to d:
DB2数据库在linux相关指令之11．绑定存储过程
DB2 connect to o_yd user DB2 using pwd
DB2 bind c:dfplus.bnd
拷贝存储过程到服务器上的C:sqllibfunction目录中
12．整理表
DB2 connect to o_yd user DB2 using pwd
DB2 reorg table ydd
DB2 runstats on table ydd with distribution and indexes all
13．导出表数据
DB2 export to c:dftz.txt of del select * from dftz
DB2 export to c:dftz.ixf of ixf select * from dftz
14．导入表数据
import from c:123.txt of del insert into ylbx.czyxx
DB2 import to c:dftz.txt of del commitcount 5000 messages c:dftz.msg insert into dftz
DB2 import to c:dftz.ixf of ixf commitcount 5000 messages c:dftz.msg insert into dftz
DB2 import to c:dftz.ixf of ixf commitcount 5000 insert into dftz
DB2 import to c:dftz.ixf of ixf commitcount 5000 insert_update into dftz
DB2 import to c:dftz.ixf of ixf commitcount 5000 replace into dftz
DB2 import to c:dftz.ixf of ixf commitcount 5000 create into dftz (仅IXF)
DB2 import to c:dftz.ixf of ixf commitcount 5000 replace_create into dftz (仅IXF)
15．执行一个批处理文件
DB2 -tf 批处理文件名
（文件中每一条命令用 ；结束）
16．自动生成批处理文件
建文本文件：temp.sql
select 'runstats on table DB2.' || tabname || '
with distribution and detailed indexes all;'
from syscat.tables where tabschema='DB2' and type='T';
DB2 -tf temp.sql>runstats.sql
17．自动生成建表（视图）语句
在服务器上：C:sqllibmisc目录中
DB2 connect to o_yd user DB2 using pwd
DB2look -d o_yd -u DB2 -e -p -c c:o_yd.txt
DB2数据库在linux相关指令之18．其他命令
grant dbadm on database to user bb
19select * from czyxx fetch first 1 rows only
20DB2look -d ylbx -u DB2admin -w -asd -a -e -o a.txt21. 显示当前用户所有表
list tables
22.列出所有的系统表
list tables for system
23.查看表结构
DB2 describe select * from user.tables
