# When should I use the change control button?

The following article describes when you should use the Change Control button in the Pharos Administrator to initiate a change or system update.

---

Clicking the Change Control button propagates information from the Database to all Pharos services. A Change Control is only required if you change some of the information that is cached at servers.

### **You should use the Change Control button after you:**

- Update a Bank
- Update a Logon DLL
- Update Print Server settings
- Update Spool Queue or Printer settings
- Update Job Cost Methods
- Update Copier settings
- Update Terminal settings (where you are using PS20 devices, you also need to stop and start the Monitor Translator)
- Update a Pharos Remote Layout
- Update a Pharos Station
- Update Pharos Popup Questions
- Update any SignUp Global Parameters
- Update any SignUp Branch Settings
- Change Access Times
- Change Prompts
- Change Server Properties
- Update Scripts

### **You do not need to use the change control button when you:**

- Update User information
- Update User Group information
- Update Discount Rates
- View Transactions
- Update Packages
- Add a Message of the Day
- View Alerts
- Set up an Export Profile
- Open a Support Incident
- View License Limits
- View Server properties

Please note there are situations (such as updating a script) where a service may behave inconsistently until a change control is issued.
