The TAO Platform provides a Maintenance Mode aiming at helping administrators to shut down the system while maintaining it. To do so, you need to change a PHP constant in the Generis configuration file. It is located at /generis/common/config.php.

To set the system in Maintenance Mode, find the following constant and set it to false.

# application state
define('SYS_READY', false);

Users will then see the following page to be informed that the platform is under maintenance.

Client scripts will receive the following json

{"success":false,"type":"Exception","message":"TAO is under maintenance","data":{"ExceptionType":"common_exception_SystemUnderMaintenance"}}

To make the system running again and available to your users, set the SYS_READY constant to true.

# application state
define('SYS_READY', true);
