      Then hit Ctrl+x to Save and Exit from nano Editor
      Add or amend the following lines

      #### Oracle 12c R2 Kernel Parameters ####
      fs.suid_dumpable = 1
      fs.aio-max-nr = 1048576
      fs.file-max = 6815744
      kernel.shmall = 818227
      kernel.shmmax = 4189323264
      kernel.shmmni = 4096
      kernel.panic_on_oops = 1
      # semaphores: semmsl, semmns, semopm, semmni
      kernel.sem = 250 32000 100 128
      net.ipv4.ip_local_port_range = 9000 65500

      The Values of ‘shmall’ and ‘shmmax’ Need to be Customized following your System Memory Size.
      Here above is a Valid Setup for a 8Gb RAM Size!
      If you need to Change first Check your Phisical Memory Size with:

      cat /proc/meminfo | grep MemTotal

      Then ‘shmall’ should be Set as:

      [RamKb] / 10

      And instead ‘shmmax’ as:

      [RamKb] * 1024 / 2

      For further Instructions See Oracle Documentation

      If Exists then Comment out these lines below that Gives an Error

      #net.bridge.bridge-nf-call-ip6tables = 0
      #net.bridge.bridge-nf-call-iptables = 0
      #net.bridge.bridge-nf-call-arptables = 0
