2、查看系统版本

   cat /proc/version

   lsb_release  –id

3、查看内核版本是否满足需求

   uname –a

   Linux dg 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686 i386 GNU/Linux

4、检查oracle11.2在linux5.5下所需的rpm包

   rpm –qa|grep **

5、修改系统资源限制

   Vi /etc/security/limits.conf

    oracle              soft    nproc   2047

oracle              hard    nproc   16384

oracle              soft    nofile  1024

oracle              hard    nofile  65536

oracle              soft    stack   10240

6、修改内核参数

   Vi  /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

   使其立即生效   sysctl  -p

7、准备安装目录及用户进行安装
