DB2_安裝配置__V9onLinux安裝以及設置windows客戶段的遠程訪

 9月份，實施過一次DB2 V9 on AIX5304的熱備雙機，剛剛接到1個case，說裏面有個表空間報“不可存取表空間”錯誤，有一陣沒有摸DB2了，於是在虛擬機上動手裝了一遍，並且在windows上安裝了db2 v9 client,同時設置遠程訪問，下面是具體的過程：

 

一、安裝db2 v9服務器、創建實例、創建管理服務器

 

1.創建目錄、用戶
[root@seagull /]# mkdir /db2home
[root@seagull /]# mkdir /db2home/db2inst1
[root@seagull /]# mkdir /db2home/db2fenc1
[root@seagull /]# groupadd -g 999 db2iadm1
[root@seagull /]# groupadd -g 998 db2fadm1

[root@seagull /]# useradd -u 1004 -g db2iadm1 -d /db2home/db2inst1 db2inst1
[root@seagull /]# useradd -u 1003 -g db2fadm1 -d /db2home/db2fenc1 db2fenc1

passwd db2inst1
passwd db2fenc1

su - db2fenc1  --切換用戶
su - db2fenc1  --根據提示，重新設置密碼，使得密碼生效
su - db2inst1  --切換用戶
su - db2inst1  --根據提示，重新設置密碼，使得密碼生效

 

2.安裝db2軟件
[root@seagull seagull]# cd /tmp/seagull/db2v9/
[root@seagull db2v9]# ls
db2  db2_install  db2setup  installFixPack

[root@seagull db2v9]# ./db2_install
#註解：IBM工程師建議用文字界面安裝，而不要用圖形界面安裝，即用db2_install,不要用db2setup

3.安裝license

5.創建das管理服務器

 

  爲了遠程客戶端能夠用控制中心來控制數據庫服務器，需要在數據庫服務器上安裝das,當然，如果只是遠程連接而不是遠程管理，可以不用裝，這裏我安裝了一下。

[root@seagull ~]# groupadd -g 997 db2asgrp
[root@seagull ~]# mkdir /db2home/db2as
[root@seagull ~]# useradd -u 1002 -g db2asgrp -d /db2home/db2as db2as

[root@seagull ~]# passwd db2as

[root@seagull ~]# su - db2as #爲了db2as口令生效

[root@seagull ~]# cd /opt/ibm/db2/V9.1/instance

[root@seagull instance]# ./dascrt -u db2as

[db2as@seagull ~]$

[db2as@seagull ~]$ exit

[root@seagull instance]# su - db2as

[db2as@seagull ~]$ db2admin start

 

6.確認一下db2inst1實例的服務名

 

[db2inst1@seagull ~]$ db2 get dbm cfg|grep SVCENAME
 TCP/IP Service name                          (SVCENAME) = 50000

#註解：svcename在客戶端連接時需要用到

 

7.可以看一下license情況

 

[db2inst1@seagull ~]$ db2licm -l
Product name:                     "DB2 Enterprise Server Edition"
License type:                     "CPU"
Expiry date:                      "Permanent"
Product identifier:               "db2ese"
Version information:              "9.1"
Annotation:                       "-3;(_c)"
Features:
DB2 Database Partitioning:        "Licensed"
DB2 Performance Optimization ESE: "Not licensed"
DB2 Storage Optimization:         "Not licensed"
DB2 Advanced Access Control:      "Not licensed"
DB2 Geodetic Data Management:     "Not licensed"
Homogeneous Federation for DB2:   "Not licensed"
DB2 Pure XML ESE:                 "Licensed"

 

 

二、安裝db2 v9 client on windows，並設置遠程連接

 

1.圖形界面安裝，一步一步下去就可以了，最好選擇不安裝信息中心。

 

2.設置遠程連接

  C:/Documents and Settings/Administrator>db2cmd
  C:/>db2 catalog tcpip node vmdb2v9 remote 10.10.10.100 server 50000
  DB20000I  CATALOG TCPIP NODE命令成功完成。
  DB21056W  只有在刷新目錄高速緩存以後，目錄更改纔會生效。

  C:/>db2 catalog db sample as sample at node vmdb2v9

  DB20000I  CATALOG DATABASE命令成功完成。
  DB21056W  只有在刷新目錄高速緩存以後，目錄更改纔會生效。

 

3.此時打開控制中心，就可以操作遠程的數據庫了。

 

 

三、基本操作命令練習

 

[db2inst1@seagull ~]$ db2level  #查看版本
DB21085I  Instance "db2inst1" uses "32" bits and DB2 code release "SQL09010"
with level identifier "02010107".

[db2inst1@seagull ~]$ db2 get db cfg|grep code #查看數據庫字符集

#註解，在客戶端，要設置db2codepage變量與數據庫一致，這樣才能正確的顯示漢字，客戶端設置方法db2set db2codepage=1208，在windows 上，db2codepage默認爲1386(GBK),linux上默認爲1208(UTF-8),aix上默認爲819(ISO8859-1)，要注意這個問題，我在客戶端查詢t1表時就發現是亂碼，後來設置了客戶端變量db2codepage才搞定。

  另外一種可行的辦法是，在服務器上創建生產庫時，指定數據庫字符集爲GBK，這樣windows客戶端就不用改db2codepage變量了，這個方法我以前用過，當時在服務器上創建生產數據庫的腳本爲：

 

su - db2inst1<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

db2set db2codepage=1386  #爲了能創建gbk字符集數據庫

exit  #退一次爲了使得設置生效

su - db2inst1

個人註解：

  DB2感覺很容易裝啊，比oracle要簡單多了，而且管理好像也簡單，只不過db2不支持rac模式，db2自己的dpf模式，和rac有本質差別，在其中一個數據庫節點所在的主機出現問題時，其管理的數據庫分區必須切換到正常節點才能保證整個數據庫的完整使用，而且正常情況下，數據庫分區之間可能會有比較大的網絡通信負載

  看來oracle的rac機制還是比較難實現的。
