DB2數據庫的正確安裝步驟簡介
DB2數據庫的優秀性勿須多言，本文將問您介紹DB2數據庫安裝的正確操作步驟，如果您對DB2數據庫安裝有興趣的話，不妨一看，對您將有所幫助。
一、DB2安裝過程
1 新建3個組，分別為管理組件das組，實例inst組，守護def組。隨后在三個組中分別加入對應的用戶：das，inst，和def。注意的是inst 用戶>同時屬于das組。為各個用戶建立目錄和密碼。
2 運行DB2SETUP后未出現向導，出現提示后退出的解決。
請不要執行DB2SETUP,請執行DB2_install，然后輸入DB2數據庫安裝的組件名字進行安裝。
3 創建實例
在/opt/IBM/DB2/v8.1/instane/下分別執行
./dascrt -u dasuser
./dasicrt -w 32 -u defuser instuser ＃如未指定位寬，則會報錯說配置文件不能正常初始化。
在/cfg/下執行DB2ln
4 設置
切換到instuser用戶下
$DB2set -g DB2COMM = TCPIP #在全局或使用-i指定某個實例的連接屬性
5 啟動數據庫
$DB2start ＃在啟動前請修改系統時間到2005年以前，否則會出現數據庫license過期的提示
建立樣表#p#
$DB2sampl
測試
$DB2 "select * from stuff"
二、DB2的初次使用
$DB2
Command Line Processor for DB2 SDK 8.2.3
You can issue database manager commands and SQL statements from the command
prompt. For example:
DB2 => connect to sample
DB2 => bind sample.bnd
For general help, type:.
For command help, type: command, where command can be
the first few keywords of a database manager command. For example:
CATALOG DATABASE for help on the CATALOG DATABASE command
CATALOG for help on all of the CATALOG commands.
To exit DB2 interactive mode, type QUIT at the command prompt. Outside #p#
interactive mode, all commands must be prefixed with 'DB2'.
To list the current command option settings, type LIST COMMAND OPTIONS.
For more detailed help, refer to the Online Reference Manual.
