When you know the current threshold values, you can change them using one of two methods:
Open /etc/sysctl.conf in a text editor.
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
Reboot the server.
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.
