禁用selinux和防火墙：
[root@db12c Packages]# vim /etc/selinux/config [root@db12c Packages]# systemctl start firewalld.service [root@db12c Packages]# systemctl stop firewalld.service [root@db12c Packages]# systemctl disable firewalld.service rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service' rm '/etc/systemd/system/basic.target.wants/firewalld.service' [root@db12c Packages]# setenforce
修改系统内核参数：
[root@db12c Packages]# sysctl -p fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.panic_on_oops = 1 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
修改oracle用户资源限制：
[root@db12c Packages]# tail -10 /etc/security/limits.conf #@faculty hard nproc 50 #ftp hard nproc 0 #@student - maxlogins 4 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768
配置环境变量：
export TMP=/tmp export ORACLE_HOSTNAME=db12c export ORACLE_UNQNAME=ORA12C export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1 export ORACLE_SID=ORA12C PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; alias cdob='cd $ORACLE_BASE' alias cdoh='cd $ORACLE_HOME' alias tns='cd $ORACLE_HOME/network/admin' alias envo='env | grep ORACLE' umask 022 envo
建立安装目录：
[root@db12c ~]# mkdir -p /u01/app/oracle/product/12.1.0/db_1 [root@db12c ~]# chown oracle:oinstall -R /u01/ [root@db12c ~]# systemctl mask tmp.mount ln -s '/dev/null' '/etc/systemd/system/tmp.mount' [root@db12c ~]# chmod 775 -R /u01/
