# Starting ASE

## Steps

1. To check that the `nofile` limit in `/etc/security/limits.conf` is set to at least 65535 or higher on the host machine, run the following command on the ASE host machine:

   ```
   ulimit -n
   ```

2. Change the working directory to `bin` and run the `start.sh` script.

   ### Example:

   ```
   /opt/pingidentity/ase/bin/start.sh
   Starting API Security Enforcer 4.0.2...
