1 环境概述
OS系统：SUSE10 SP1 X64
DB2版本:DB2 V9.5 for Linux 64
2 安装DB2数据库
2.1 安装前准备
2.1.1 安装必须依赖包
|
针对SUSE操作系统 libaio-32bit-0.3.104-14.2.x86_64.rpm libaio-0.3.104-14.2.x86_64.rpm compat-libstdc++-5.0.7-22.2.x86_64.rpm ksh-93r-12.28.x86_64.rpm openssl-0.9.8a-18.15.x86_64.rpm rsh-server-0.17-573.2.x86_64.rpm nfs-utils-1.0.7-36.21.x86_64.rpm |
2.1.2 系统资源限制修改
|
DB02-DB2:/db2_inst # ulimit -a data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited open files (-n) 65536 |
2.1.3 系统内核参数修改
|
请参考官方安装文档 通过编辑/etc/sysctl.conf文件来修改内核参数 以16GB RAM的就是计算机为例: kernel.shmmni=4096 kernel.shmmax=17179869184 kernel.shmall=8388608 #kernel.sem=<SEMMSL> <SEMMNS> <SEMOPM> <SEMMNI> kernel.sem=250 256000 32 4096 kernel.msgmni=16384 kernel.msgmax=65536 kernel.msgmnb=65536 4. 运行 sysctl时候附带 -p 参数，以从缺省文件/etc/sysctl.conf 中装入 sysctl 的设置： sysctl -p 要使更改在每次重新引导之后生效： (SUSE Linux)激活 boot.sysctl (Red Hat)rc.sysinit 初始化脚本将自动读取 /etc/sysctl.conf文件 |
2.1.4 创建DB2用户和用户组
|
对于Linux 操作系统 groupadd -g 999 db2iadm1 groupadd -g 998 db2fadm1 groupadd -g 997 dasadm1 useradd -u 1004 -g db2iadm1 -m -d /home/db2inst1 db2inst1 useradd -u 1003 -g db2fadm1 -m -d /home/db2fenc1 db2fenc1 useradd -u 1002 -g dasadm1 -m -d /home/dasusr1 dasusr1 passwd db2inst1 passwd db2fenc1 passwd dasusr1 |
2.2 安装DB2数据库

2.3 添加软件license
|
DB02-DB2:/opt/ibm/db2/V9.5/adm # ./db2licm -a /root/db2ese_c_v9.5.lic LIC1402I License added successfully. DB02-DB2:/opt/ibm/db2/V9.5/adm # ./db2licm -l Product name: "DB2 Enterprise Server Edition" License type: "CPU Option" Expiry date: "Permanent" Product identifier: "db2ese" Version information: "9.5" Features: DB2 Database Partitioning: "Not licensed" DB2 Performance Optimization ESE: "Not licensed" DB2 Storage Optimization: "Not licensed" DB2 Advanced Access Control: "Not licensed" DB2 Geodetic Data Management: "Not licensed" DB2 pureXML ESE: "Not licensed" IBM Homogeneous Federation ESE: "Not licensed" IBM Homogeneous Replication ESE: "Not licensed" |
2.4 建立DB2文件的链接
为DB2数据库系统文件创建指向/usr/lib目录的链接，并为包含文件创建指向/usr/include目录的链接
|
DB02-DB2:/opt/ibm/db2/V9.5/cfg # ./db2ln |
3 创建数据库实例
3.1 创建数据库实例db2inst1
|
DB02-DB2:/opt/ibm/db2/V9.5/instance # ./db2icrt -a server -u db2fenc1 db2inst1 DBI1070I Program db2icrt completed successfully. DB02-DB2:/opt/ibm/db2/V9.5/instance # |
3.2 创建DAS管理服务器实例
|
DB02-DB2:/opt/ibm/db2/V9.5/instance # ./dascrt -u dasusr1 SQL4406W The DB2 Administration Server was started successfully. DBI1070I Program dascrt completed successfully. DB02-DB2:/opt/ibm/db2/V9.5/instance # |
3.3 设置开机启动数据量实例
|
DB02-DB2:/opt/ibm/db2/V9.5/instance # su - db2inst1 [email protected]:~> db2iauto -on db2inst1 |
3.4 设置DB2通信方式
|
db2set DB2COMM=tcpip db2stop db2start |
3.5 创建sample数据库
|
[email protected]:~> db2 get instance The current database manager instance is: db2inst1 [email protected]:~> db2sampl Creating database "SAMPLE"... Connecting to database "SAMPLE"... Creating tables and data in schema "DB2INST1"... ‘db2sampl‘ processing complete. [email protected]:~> 可以指定路径和名称 [email protected]:~>db2sampl -dbpath /db2/sample -name sample |
