1．启动数据库
      db2start
2．停止数据库
      db2stop
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:
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:\sqllib\function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:\sqllib\misc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
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
