How to check the virtual memory setting

From ARIS 10 SR4, the elastic runnable (elastic search) requires more virtual memory on your Linux operating system in order to prevent indices from causing out-of-memory exceptions. On the machine where the elastic runnable is installed, check which value the vm.max_map_count system parameter is currently set to.

For this, use the sysctl vm.max_map_count command. If the value is lower than 262144, change it to 262144.

To change the value for this session only, use the following command (root access permissions required):

sudo sysctl -w vm.max_map_count=262144

This command changes the value for the current session only. After a reboot, this change is undone.

To change the value persistently, add this line to the sysctl.conf configuration file that is available in the ARIS installation directory on your machine:

vm.max_map_count=262144
