1.切换至root用户

2.uname -a/-m        grep MemTotal /proc/meminfo       grep SwapTotal /proc/meminfo       free -m   

3.df -h /tmp 至少1G空间

4.查看安装依赖软件             rpm -q package_name

5.添加用户及用户组
# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba
# id oracle
# /usr/sbin/useradd -g oinstall -G dba oracle
# passwd oracle
6.修改内核参数
 Minimum ValueFile
semmsl

semmns

semopm

semmni

 250

32000

100

128

 /proc/sys/kernel/sem
shmall 2097152 /proc/sys/kernel/shmall
shmmax Minimum: 536870912

Maximum: A value that is 1 byte less than the physical memory

Recommended: More than half the physical memory

See My Oracle Support Note 567506.1 for additional information about configuring shmmax.

 /proc/sys/kernel/shmmax
shmmni 4096 /proc/sys/kernel/shmmni
file-max 6815744 /proc/sys/fs/file-max
ip_local_port_range Minimum: 9000

Maximum: 65500

 /proc/sys/net/ipv4/ip_local_port_range
rmem_default 262144 /proc/sys/net/core/rmem_default
rmem_max 4194304 /proc/sys/net/core/rmem_max
wmem_default 262144 /proc/sys/net/core/wmem_default
wmem_max 1048576 /proc/sys/net/core/wmem_max
aio-max-nr 1048576

Note: This value limits concurrent outstanding requests and should be set to avoid I/O subsystem failures.

 /proc/sys/fs/aio-max-nr

 Command
semmsl, semmns, semopm, and semmni # /sbin/sysctl -a | grep sem

This command displays the value of the semaphore parameters in the order listed.
shmall, shmmax, and shmmni # /sbin/sysctl -a | grep shm
file-max # /sbin/sysctl -a | grep file-max
ip_local_port_range # /sbin/sysctl -a | grep ip_local_port_range
rmem_default # /sbin/sysctl -a | grep rmem_default
rmem_max # /sbin/sysctl -a | grep rmem_max
wmem_default # /sbin/sysctl -a | grep wmem_default
wmem_max # /sbin/sysctl -a | grep wmem_max 
不符合要求的,需要按照下面的格式修改/etc/sysctl.conf文件
fs.aio-max-nr = 1048576 
fs.file-max = 6815744 
kernel.shmall = 2097152 
kernel.shmmax = 536870912 
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
 
使用下面的命令使修改的内核参数生效
# /sbin/sysctl -p
