•           hard    rss            65536

•           hard    nproc          65536

•           soft    nproc          65536

  oradev soft nproc 65536
  oradev hard nproc 65536
  oradev soft nofile 65536
  oradev hard nofile 65536
  oradev soft stack 65536
  oradev hard stack 32768
  oradev hard memlock 8000000
  oradev soft memlock 8000000
  oracle soft nproc 65536
  oracle hard nproc 65536
  oracle soft nofile 65536
  oracle hard nofile 65536
  oracle soft stack 65536
  oracle hard stack 32768
  oracle hard memlock 8000000
  oracle soft memlock 8000000
  @sapsys hard nofile 32800
  @sapsys soft nofile 32800
  @dba hard nofile 32800
  @dba soft nofile 32800
  cat /etc/security/limits.d/20-nproc.conf |grep -v ^#|grep -v ^$:
  

•      soft    nproc     unlimited 

  root soft nproc unlimited

1. 系统参数配置
   cat /etc/sysctl.conf|grep -v ^#|grep -v ^$:
   fs.aio-max-nr = 1048576
   fs.file-max = 6815744
   kernel.sem = 250 32000 100 128
   net.ipv4.ip_local_port_range = 9000 65500
   net.core.rmem_default = 262144
   net.core.rmem_max = 4194304
   net.core.wmem_default = 262144
   net.core.wmem_max = 1048586
   kernel.msgmni=1024
   kernel.panic_on_oops = 1
   kernel.sem = 1250 256000 100 1024
   kernel.shmmax = 214748364800
   kernel.shmall = 52428800
   kernel.shmmni = 4096
   vm.nr_hugepages = 2500
   vm.max_map_count=2000000

2. DNS配置
   4.关闭防火墙
   5.package
   rpm -ivh compat-libcap1-1.10-7.el7.x86_64.rpm
   rpm -ivh ksh-20120801-139.el7.x86_64.rpm
   rpm -ivh libaio-devel-0.3.109-13.el7.x86_64.rpm
