You can change the ArcGIS Server site mode in ArcGIS Server Manager. To change your ArcGIS Server site mode, follow these steps.
- Open Manager and log in as a member with administrative privileges.
- Click Site > Settings.
- On the Site Settings page, click Edit.
- Click to check the Enable read-only mode check box.
Manager will display a banner indicating that the site is in read-only mode. Publishing new services and most administrative operations will be blocked. Scaling your site by adding or removing machines is still possible and the functionality of existing services continues to be available. See Administrative operations and ArcGIS Server site mode for details on which administrative operations are disabled.
