2.交换分区

Available RAMSwap Space Required

Between 1 GB and 2 GB1.5 times the size of RAM

Between 2 GB and 16 GBEqual to the size of RAM

More than 16 GB16 GB

grep "model name" /proc/cpuinfo

grep SwapTotal /proc/meminfo

[root@home ~]# free

[root@rhel5 ~]# uname -s

Linux

7. 检查软件包

yum -y install binutils-*

yum -y install compat-libstdc++-*

yum -y install elfutils-libelf-*

yum -y install elfutils-libelf-devel-*

yum -y install elfutils-libelf-devel-static-*

yum -y install gcc-*

yum -y install gcc-c++-*

yum -y install glibc-*

yum -y install glibc-common-*

yum -y install glibc-devel-*

yum -y install glibc-headers-*

yum -y install kernel-headers-*

yum -y install ksh-*

yum -y install libaio-*

yum -y install libaio-devel-*

yum -y install libgcc-*

yum -y install libgomp-*

yum -y install libstdc++-*

yum -y install libstdc++-devel-*

yum -y install make-*

yum -y install sysstat-*

yum -y install unixODBC-*

yum -y install unixODBC-devel-*

8. 创建组和用户

/usr/sbin/groupadd oinstall

/usr/sbin/groupadd dba

/usr/sbin/useradd -g oinstall -G dba oracle

如果oracle用户已经存在

/usr/sbin/usermod -g oinstall -G dba oracle

echo oracle | passwd --stdin oracle

9. 修改内核参数 vi /etc/sysctl.conf

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 = 1048586

10. vi /etc/security/limits.conf

oracle          soft    nproc  2047

oracle          hard    nproc  16384

oracle          soft    nofile  1024

oracle          hard    nofile  65536

11. vi /etc/pam.d/login

session    required    pam_limits.so

12. 修改profile

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

13. 创建目录结构

mkdir -p /u01/app

chown -R oracle:oinstall /u01/app

chmod -R 775 /u01/app

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1

export ORACLE_SID=orcl

export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

14. runInstaller
