引數：

/etc/sysctl.conf

fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104

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

/sbin/sysctl -p 來應用

OS 引數：

/etc/security/limits.conf

oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768

賬號和組

groupadd -g 101 oinstall
groupadd -g 102 dba
groupadd -g 103 oper

useradd -u 100 -g oinstall -G dba,oper oracle

passwd oracle

資料夾許可權

chown -R oracle:oinstall /u01/database

chmod -R 775 /u0/database
mkdir -p /u01/app/oracle/product/12.1.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

然後就開始安裝。
