在之前的文章中我推荐过使用oracle-validated RPM包来简化OEL 5上Oracle DB/RDBMS Server软件的安装准备工作， 而在OEL 6之后的Oracle Linux中一直没有oracle-validated RPM可用，直到最近Oracle Linux官方释出了oracle-rdbms-server-11gR2-preinstall RPM包，该oracle-rdbms-server-11gR2-preinstall package专门为Oracle Linux 6设计，辅助加速Oracle Database软件的安装。
我们可以访问 Unbreakable Linux Network 或者 Oracle public yum repository 获得该preinstall package RPM，这里我们介绍一下public yum的使用方法：

注意该oracle-rdbms-server-11gR2-preinstall目前只有x86-64位的版本，即在x86的Oracle Linux 6上不可用。
与oracle-validated RPM类似，oracle-rdbms-server-11gR2-preinstall会为我们完成以下工作：
1. 从oracle Public YUM上下载并安装多个特定的软件包并保证其为指定的版本(如以上示例)，这些软件包software package是安装Oracle DB/RDBMS Server 11gR2数据库软件的先决条件之一
2. 创建 oracle OS用户user，以及 oinstall 和 dba 用户组group
3. 修改/etc/sysctl.conf配置文件中的内核参数，以保证oracle instance实例可以健康运行
安装完成后的 /etc/sysctl.conf 内容如下：
[root@vrh6 yum.repos.d]# cat /etc/sysctl.conf # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls IP packet forwarding net.ipv4.ip_forward = 0 # Controls source route verification net.ipv4.conf.default.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 # Controls the System Request debugging functionality of the kernel kernel.sysrq = 0 # Controls whether core dumps will append the PID to the core filename. # Useful for debugging multi-threaded applications. kernel.core_uses_pid = 1 # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 1 # Disable netfilter on bridges. net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 # Controls the maximum size of a message, in bytes kernel.msgmnb = 65536 # Controls the default maxmimum size of a mesage queue kernel.msgmax = 65536 # Controls the maximum shared segment size, in bytes # Controls the maximum number of shared memory segments, in pages # oracle-rdbms-server-11gR2-preinstall setting for fs.file-max is 6815744 fs.file-max = 6815744 # oracle-rdbms-server-11gR2-preinstall setting for kernel.sem is '250 32000 100 128' kernel.sem = 250 32000 100 128 # oracle-rdbms-server-11gR2-preinstall setting for kernel.shmmni is 4096 kernel.shmmni = 4096 # oracle-rdbms-server-11gR2-preinstall setting for kernel.shmall is 1073741824 kernel.shmall = 1073741824 # oracle-rdbms-server-11gR2-preinstall setting for kernel.shmmax is 4398046511104 on x86_64 kernel.shmmax = 4398046511104 # oracle-rdbms-server-11gR2-preinstall setting for net.core.rmem_default is 262144 net.core.rmem_default = 262144 # oracle-rdbms-server-11gR2-preinstall setting for net.core.rmem_max is 4194304 net.core.rmem_max = 4194304 # oracle-rdbms-server-11gR2-preinstall setting for net.core.wmem_default is 262144 net.core.wmem_default = 262144 # oracle-rdbms-server-11gR2-preinstall setting for net.core.wmem_max is 1048576 net.core.wmem_max = 1048576 # oracle-rdbms-server-11gR2-preinstall setting for fs.aio-max-nr is 1048576 fs.aio-max-nr = 1048576 # oracle-rdbms-server-11gR2-preinstall setting for net.ipv4.ip_local_port_range is 9000 65500 net.ipv4.ip_local_port_range = 9000 65500
4. 修改/etc/security/limits.conf配置文件 保证 oracle用户的shell soft/hard limit，例如nofile、stack等参数足够， 以符合Oracle 11gR2的安装要求
安装完成后的 /etc/security/limits.conf内容如下：
# oracle-rdbms-server-11gR2-preinstall setting for nofile soft limit is 1024 oracle soft nofile 1024 # oracle-rdbms-server-11gR2-preinstall setting for nofile hard limit is 65536 oracle hard nofile 65536 # oracle-rdbms-server-11gR2-preinstall setting for nproc soft limit is 2047 oracle soft nproc 2047 # oracle-rdbms-server-11gR2-preinstall setting for nproc hard limit is 16384 oracle hard nproc 16384 # oracle-rdbms-server-11gR2-preinstall setting for stack soft limit is 10240KB oracle soft stack 10240 # oracle-rdbms-server-11gR2-preinstall setting for stack hard limit is 10240KB oracle hard stack 32768
5. 为 x86-64的服务器设置kernel boot 内核启动参数numa=off ，关闭numa功能：
[root@vrh6 ~]# cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
