# Configuring system parameters manually

## About this task

If the configured user does not have `sudo` access, then manually edit the `vm.max_map_count` and `ulimit` values:

## Steps

1. Set the `vm.max_map_count` to `262144` on the Elasticsearch virtual machine (VM) by entering the following command:

   ```shell
   $sudo sysctl -w vm.max_map_count=262144
   ```

2. To make the setting persistent across reboots, run the following command:

   ```shell
   $sudo echo "vm.max_map_count=262144" >> /etc/sysctl.conf
   ```

3. Set the `ulimit` to `65536` on the ASE, ABS, MongoDB, and Elasticsearch hosts. To set the `ulimit`:

   1. Edit `/etc/security/limits.conf` for increasing the soft limit and hard limit.

   2. Add the following two lines for the user that you have created (for example, `pi-user`):

      ```
      pi-user soft nofile 65536
      pi-user hard nofile 65536
      ```

      |   |                                                                                                    |
      | - | -------------------------------------------------------------------------------------------------- |
      |   | If the number of APIs in the environment is greather than 1500, then set the `ulimit` to `131070`. |
