 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:\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';
