System configuration

On Linux

• use a text editor to edit the /etc/sysctl.conf file. Add or edit each of the following parameter definitions to set the required value. 

     kernel.shmmax = 1000000000
     kernel.shmmni = 4096
     kernel.shmall = 4000000000
     kernel.sem = 250 512000 100 2048
     kernel.sysrq = 1
     kernel.core_uses_pid = 1
     kernel.msgmnb = 65536
     kernel.msgmax = 65536
     kernel.msgmni = 2048
     net.ipv4.tcp_syncookies = 0
     net.ipv4.ip_forward = 0
     net.ipv4.conf.default.accept_source_route = 0
     net.ipv4.tcp_tw_recycle = 1
     net.ipv4.tcp_max_syn_backlog = 200000
     net.ipv4.conf.all.arp_filter = 1
     net.ipv4.ip_local_port_range = 1281 65535
     net.core.netdev_max_backlog = 200000
     vm.overcommit_memory = 2
     fs.nr_open = 3000000
     kernel.threads-max = 798720
     kernel.pid_max = 798720
     # increase network
     net.core.rmem_max=2097152
     net.core.wmem_max=2097152

• Execute the following command to apply your updated /etc/sysctl.conf file to the operating system configuration:
  

  sysctl -p

• Use a text editor to edit the /etc/security/limits.conf file. Add the following definitions in the exact order that they are listed

     * soft nofile 2900000
     * hard nofile 2900000
     * soft nproc 131072
     * hard nproc 131072

On MAC

• use a text editor to edit the /etc/sysctl.conf file. Add or edit each of the following parameter definitions to set the required value. 

        kern.sysv.shmmax=2147483648

        kern.sysv.shmmin=1

        kern.sysv.shmmni=64

        kern.sysv.shmseg=16

        kern.sysv.shmall=524288

        kern.maxfiles=65535

        kern.maxfilesperproc=65536

• restart to apply the change
