第一次在Linux上安装DB2,参考了很多的网上资源,但是主要的是“Linux下安装DB2 version 8.1 的详细步骤”。
同时把自己遇到的问题住了一个记录,以做学习之用。

VMWARE使用的是VMware  server  1.0.6,Linux的内核版本是:Linux node1 2.6.18-53.el5PAE

Root 权限操作:

第一步:检查程序包及其版本
   compat-libstdc++-7.3-2.96.118.i386.rpm
     在linux的安装盘上,找到后使用rpm -i compat-libstdc++-7.3-2.96.118.i386.rpm 安装即可

第二步:配置 Linux 内核参数
        /etc/sysctl.conf文件,添加内核参数
        kernel.msgmni =1024
        kernel.sem = 250 256000  32 1024
        使更改激活:sysctl –p

第三步:安装
       sh db2_install
       按照提示做

第四步:创建用户
  /usr/sbin/groupadd db2iadm1
  /usr/sbin/groupadd db2fadm1
  /usr/sbin/useradd –m -g db2iadm1 –d /home/db2inst1 db2inst1
  /usr/sbin/useradd –m -g db2fadm1 –d /home/db2fenc1 db2fenc1

第五步:创建实例
  /opt/IBM/db2/V8.1/instance/db2icrt –a server –u db2fenc1 db2inst1

** please can go into /opt/IBM/db2/V8.1/instance, find file db2iutil
and replace all 'tail +2' with 'tail -n +2' if you meet error.

第六步:产品许可证
  /opt/IBM/db2/V8.1/adm/db2licm -a /mnt/cdrom/db2/license/db2pe.lic

第七步:允许SMS的多页分配
        /opt/IBM/db2/V8.1/cfg/db2ln

#第八步:添加DB2端口
#       SU - root
#        vi /etc/services 加入下面一行
#        db2inst1   50000/tcp
这一步是不需要的,系统自定添加,但是有可能需要更改一下,我的是这样的:

DB2_db2inst1    50000/tcp
DB2_db2inst1_1  50001/tcp
DB2_db2inst1_2  50002/tcp
DB2_db2inst1_END        50003/tcp

以下是DB2 用户操作

第九步:DB2 配置
 su – db2inst1
 db2set DB2_EXTENDED_OPTIMIZATION=ON
 db2set DB2_DISABLE_FLUSH_LOG=ON
 db2set AUTOSTART=YES
 db2set DB2_STRIPED_CONTAINERS=ON
 db2set DB2_HASH_JOIN=Y
 db2set DB2COMM=tcpip
 db2set DB2_PARALLEL_IO=*
 db2set DB2CODEPAGE=819

 #Update dbm cfg
 db2 update dbm cfg using SVCENAME db2inst1
 db2 update dbm cfg using INDEXREC ACCESS

第十步:运行DB2
        db2start

If raised error message:
Please check   $DB2_home/sqllib/db2nodes.cfg, /etc/hosts  uname -n,, confirm that all the node name is same.


第十一步:创建库
        db2 "CREATE DATABASE test1 on /opt/IBM/tony/ USING CODESET ISO8859-1 TERRITORY CN"
以后就可以创建表和对表操作了,如 db2 "select * from sysibm.sysdummy1"


客户端操作:
1. catalog DB

db2 catalog tcpip node DS_NODE  remote 192.168.102.128 server 50000
db2 catalog db test1 as ds_test1 at node  ds_node

2. DB2 的一个常见连接错误出现:

db2 connect to ds_test1 user db2inst1 using 123456
SQL30081N  A communication error has been detected. Communication protocol
being used: "TCP/IP".  Communication API being used: "SOCKETS".  Location
where the error was detected: "192.168.102.128".  Communication function
detecting the error: "connect".  Protocol specific error code(s): "10061", "*",
"*".  SQLSTATE=08001

把dbm的VCENAME 的值和/etc/services中的端口号对应
db2 update dbm cfg using SVCENAME 50000

3. restart DB
db2stop force
db2start
db2 activate db test1

4. 参数确认
[db2inst1@node1 C]$ db2set -all
[i] DB2COMM=TCPIP
[g] DB2_EEE_LICENSE_POLICY=4295032864
[db2inst1@node1 C]$ netstat -an | grep 50000

确认DB2COMM 参数已经设置,同时50000端口已经启动

5.出现pagecode错误
db2 connect to ds_test1 user db2inst1 using 123456
SQL0332N  Character conversion from the source code page "1114" to the target
code page "UNKNOWN" is not supported.  SQLSTATE=57017

**原因:连接的数据库使用的代码页设置(819)与本地客户端设置的代码页(1386)不同 之间无法进行双向转换,
即无法将GBK 编码的字符转换为ISO-8859-1字符,解决方法:

db2set DB2CODEPAGE=819

db2 terminate
DB20000I  The TERMINATE command completed successfully.

db2 connect to ds_test1 user db2inst1 using 123456

  Database Connection Information

 Database server        = DB2/LINUX 8.1.0
 SQL authorization ID   = DB2INST1
 Local database alias   = DS_TEST1

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
