4.3 Changing the Current Kernel Threshold Value

When you know the current threshold values, you can change them using one of two methods:

4.3.1 Editing the /etc/sysctl.conf File

  1. Open /etc/sysctl.conf in a text editor.

  2. Add the following lines to the .conf file:

    net.ipv4.neigh.default.gc_thresh1 = 256 

net.ipv4.neigh.default.gc_thresh2 = 1024 

net.ipv4.neigh.default.gc_thresh3 = 2048

  3. Reboot the server.

4.3.2 Making Live Changes to the Threshold Values

To make changes to a given threshold on the Orchestrate Server you can run a command for each threshold that you want to change, for example: 

# echo '256' > /proc/sys/net/ipv4/neigh/default/gc_thresh1

After you run the command, perform a /etc/init.d/network restart command to restart the Orchestrate Server and put the changes in place.

NOTE:This method of changing the threshold values is volatile: if you reboot the SLES server, the changes are lost.
