DB2創建用戶是很常見的操作，下面就為您詳細介紹DB2創建用戶的方法，如果您在DB2創建用戶方面遇到過類似的問題，不妨一看。

1.創建實例用戶
mkdir /db2/db2test 創建實例用戶目錄
smitty user
選擇Add a User
* User NAME                                          [db2test]                                                            
User ID                                                   []                                                                   
ADMINISTRATIVE USER?                       false                                                              
Primary GROUP                                     [db2iadm1]                                                          
Group SET                                           [staff]                                                             
ADMINISTRATIVE GROUPS                   []                                                                  
ROLES                                                         []

Initial PROGRAM                                    [/usr/bin/ksh]

2.創建實例 DB2_install=/usr/opt/db2_08_01/instance
./db2icrt -u db2test db2test

3.創建數據庫
su - db2test
db2start     #此處不執行啟動實例將報:SQL1032N No start database manager command was issued. SQLSTATE=57019
db2 create db db2test

4.刪除數據庫
db2 drop db db2test
db2stop

5.刪除實例
cd DB2_install
./db2idrop -f db2test # -f參數一定要添加否則刪除完了會報錯！

6.刪除用戶
smitty user
