Configuring the sysctl.conf File

Configuring the sysctl.conf File

  1. Run the vi /etc/sysctl.conf command to open the sysctl.conf file.
  2. Add the following parameters:

    kernel.hung_task_timeout_secs = 600
    kernel.watchdog_thresh = 60
    kernel.watchdog = 1

  1. Add fs.aio-max-nr=196608.

    NOTE:

    To prevent the HANA database from reporting errors, you need to add the fs.aio-max-nr parameter before installing the HANA database.

  1. Press Esc and run :wq to save the configuration and exit.
  2. Run the following commands:

    sysctl -w net.core.netdev_max_backlog=250000
    sysctl -w net.core.optmem_max=16777216
    sysctl -w net.core.rmem_default=16777216
    sysctl -w net.core.rmem_max=16777216
    sysctl -w net.core.wmem_max=16777216
    echo 1 > /proc/sys/net/ipv4/tcp_moderate_rcvbuf
    echo "4096 87380 4194304" > /proc/sys/net/ipv4/tcp_rmem
    echo "4096 16384 4194304" > /proc/sys/net/ipv4/tcp_wmem
    echo "12406293 16541726 24812586" >/proc/sys/net/ipv4/tcp_mem
    sysctl -p /etc/sysctl.conf

  1. Add the following commands to /etc/init.d/mountinit. This ensures that configuration takes effect even after the system is restarted.

    sysctl -w net.core.netdev_max_backlog=250000
    sysctl -w net.core.optmem_max=16777216
    sysctl -w net.core.rmem_default=16777216
    sysctl -w net.core.rmem_max=16777216
    sysctl -w net.core.wmem_max=16777216
    echo 1 > /proc/sys/net/ipv4/tcp_moderate_rcvbuf
    echo "4096 87380 4194304" > /proc/sys/net/ipv4/tcp_rmem
    echo "4096 16384 4194304" > /proc/sys/net/ipv4/tcp_wmem
    echo "12406293 16541726 24812586" >/proc/sys/net/ipv4/tcp_mem
