    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 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: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

    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
