在SUSE10SP1上安装DB2v9.5数据库

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=
kernel.sem=250 256000 32 4096
kernel.msgmni=16384
kernel.msgmax=65536
kernel.msgmnb=65536
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
DB02-DB2:/db2_inst # tar xf db2_v95_linuxx64_server.tar.gz
DB02-DB2:/db2_inst # ls -lrt
