SUSE10 SP1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=<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

DB02-DB2:/db2_inst # tar xf db2_v95_linuxx64_server.tar.gz DB02-DB2:/db2_inst # ls -lrt total 610384 drwxr-xr-x 4 root root      4096 Oct  6   2007 server drwx------ 5 root root      4096 Oct 10 19:19 db2lic -rw------- 1 root root 624408392 Oct 10 19:19  db2_v95_linuxx64_server.tar.gz DB02-DB2:/db2_inst # cd server DB02-DB2:/db2_inst/server # ls -lrt total 48 -r-xr-xr-x  1 bin  bin 4560 Oct  6  2007 db2prereqcheck -r-xr-xr-x  1 bin  bin 4552 Oct  6  2007 db2setup -r-xr-xr-x  1 bin  bin 4570 Oct  6  2007 db2_install -r-xr-xr-x  1 bin  bin 4700 Oct  6  2007 db2_deinstall drwxr-xr-x 15 bin bin 4096 Oct  6   2007 doc -r-xr-xr-x  1 bin  bin 4588 Oct  6  2007 installFixPack drwxr-xr-x  6 bin  bin 4096 Oct  6  2007 db2 DB02-DB2:/db2_inst/server # ./db2_install   Default directory for installation of products -  /opt/ibm/db2/V9.5   *********************************************************** Do you want to choose a different directory to install  [yes/no] ? no     Specify one of the following keywords to install DB2  products.     ESE   CONSV   WSE   EXP   PE   CLIENT   RTCL   Enter "help" to redisplay product names.   Enter "quit" to exit.   *********************************************************** ESE DB2 installation is being initialized.   Total number of tasks to be performed: 43 Total estimated time for all tasks to be performed:  1688 …………………………………………（省略N行） The execution completed successfully.   For more information see the DB2 installation log at "/tmp/db2_install.log.4423". DB02-DB2:/db2_inst/server #

 

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 db2inst1@DB02-DB2:~>  db2iauto -on db2inst1

 

3.4   设置DB2通信方式
