# Automatically update code on Linux instances AMS automatically updates on instance code on Linux instances. This helps to improve operational stability and security of the AMS components and environment altogether. **FAQ:** What's included in the On Instance Code (OIC) on Linux? OIC includes ams-toolkit package along with some configuration files and cron jobs. AMS require these files and packages for integration (Active Directory, CloudFormation and other dependencies). We pre-bake these files into AMS-provided AMIs or install onto your instance during workload ingestion. When will AMS update OIC? AMS update OIC when we release a new version with bug fixes or other improvements. The workflow to check the OIC version and update runs daily.
