  9. 禁用selinux和防火墙：

  10. [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

  11. 修改系统内核参数：

  12. [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

  13. 修改oracle用户资源限制：

  14. [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

  15. 配置环境变量：

  16. 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

  17. 建立安装目录：

  18. [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/
