db2 常用命令

1．啓動數據庫
     db2start
2．停止數據庫
     db2stop
3．連接數據庫
     db2 connect to o_yd user db2 using pwd
4．讀數據庫管理程序配置
     db2 get dbm cfg
5．寫數據庫管理程序配置
     db2 update dbm cfg using 參數名 參數值
6．讀數據庫的配置
     db2 connect to o_yd user db2 using pwd
     db2 get db cfg for o_yd
7．寫數據庫的配置
     db2 connect to o_yd user db2 using pwd
     db2 update db cfg for o_yd using 參數名 參數值
8．關閉所有應用連接
     db2 force application all
     db2 force application ID1,ID2,,,Idn MODE ASYNC
     (db2 list application for db o_yd show detail)
9．備份數據庫
     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．恢復數據庫
    db2 restore db o_yd from d: to d:
    db2 restore db o_yd from //./tape0 to d:
11．綁定存儲過程
   db2 connect to o_yd user db2 using pwd
   db2 bind c:/dfplus.bnd
  拷貝存儲過程到服務器上的C:/sqllib/function目錄中
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．導出表數據
     db2 export to c:/dftz.txt of del select * from dftz
     db2 export to c:/dftz.ixf of ixf select * from dftz
14．導入表數據
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   (僅IXF)
db2 import to c:/dftz.ixf of ixf commitcount 5000 replace_create into dftz  (僅IXF)

15．執行一個批處理文件
       db2 –tf 批處理文件名
      （文件中每一條命令用 ；結束）
16．自動生成批處理文件
     建文本文件：temp.sql
   select 'runstats on table DB2.' || tabname || ' with distribution and  detailed indexes all&#59;' from syscat.tables where tabschema='DB2' and type='T'&#59;
db2 –tf temp.sql>;runstats.sql
17．自動生成建表（視圖）語句
在服務器上：C:/sqllib/misc目錄中
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. 顯示當前用戶所有表

　　list tables
22.列出所有的系統表

　　list tables for system
23.查看錶結構
　　db2 describe select * from user.tables
