两节点修改内核参数配置
1. 修改/etc/sysctl.conf配置
vi /etc/sysctl.conf
kernel.shmmax = 139586437120
kernel.shmall = 34078720
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65500
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
sysctl -p
2. 修改/etc/security/limits.conf
# vi /etc/security/limits.conf

oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
# vi /etc/pam.d/login
session required pam_limits.so
修改文件/etc/pam.d/su，追加以下内容（如果不存在）。
vi /etc/pam.d/su
session required pam_limits.so
修改文件/etc/profile（根据SUSE版本不同，名字可能叫/etc/profile），追加以下内容（如果不存在）。
vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536

设置操作系统的共享内存大小
操作步骤
步骤 1 以root用户登录。
步骤 2 检查操作系统共享内存大小。
# df -m| grep shm
Filesystem 1K-blocks Used Available Use% Mounted on
shm 16777216 1131136 15646080 7% /dev/shm
如果/dev/shm的文件系统大小为物理内存大小，则表示已经正确设置。否则需要重新设置。
步骤 3 卸载/dev/shm文件系统。
# umount /dev/shm
如果提示“device is busy”则需要停止数据库。
步骤 4 挂载/dev/shm文件系统。
内存大小请根据实际情况填写。
# mount -t tmpfs shmfs -o size=16g /dev/shm
步骤 5 修改文件/etc/fstab，追加以下内容：
shm /dev/shm tmpfs size=16g 0 0
ssh互信
虽然可以在安装过程中图形化配置互信，
但提前配置的目的是便于执行安装先决条件检查
