DB2 V9.7 Installation on RHEL5

DB2安装前需要修改配置内核参数,修改/etc/sysctl.conf

shmall默认是8G,建议将此参数设置为DB2服务器物理内存的90%,如果内存是16G,就是(16*0.9*1024*1024)/4=3774873,当前环境的物理内存是2G,也就是(2*0.9*1024*1024)/4=471859

shmmax建议和系统物理内存相等,在64位系统上必须至少设置为1G,即1073741824

net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.msgmni = 1024
kernel.shmmax = 2147483648
kernel.shmall = 471859
kernel.sem = 250 256000 32 1024

kernel.randomize_va_space = 0

 

创建libpam.so软链接,具体参考IBM DB2解决方案 

IC87092: DB2PREREQCHECK GIVES WARNING "THE 32-BIT LIBRARY FILE LIBPAM.SO IS NOT FOUND ON THE SYSTEM." WHEN THE REQUIRED LIBPAM.SO.0 EXIST

[root@db2test server]# ln -s /lib/libpam.so.0.81.5 /lib/libpam.so

 

安装DB2软件

[root@db2test server]# ./db2setup
