自己安装Oracle时，遇到的一些配置参数

chown -R oracle. database/ # 这里的”oracle.”的作用是什么？

yum -y groupinstall “Graphical Administration Tools”
yum -y groupinstall “General Purpose Desktop”
yum -y groupinstall “Graphics Creation Tools”

yum install -y binutils

3. 内核参数调整（不低于以下值）
   vi /etc/sysctl.conf
   最后一行添加

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
加载参数
sysctl -p

kernel.shmmax = 68719476736
kernel.shmall = 4294967296
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096

WARNING:It is recommended to not use the Oracle Base /home/oracle as the user home directory

sh: /bin/ksh: No such file or directory –. 这个内容果然还是应该修改为/bin/sh
