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 –udb2fenc1db2inst1
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
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
第十一步：创建库
db2 CREATE DATABASE test1 ALIAS test1 USING CODESETISO8859-1TERRITORY CN
以后就可以创建表和对表操作了，如 db2 select * from tbl
