Maintenance Mode
A Project Database can be put into a state preventing users from using the application during a database maintenance event, such as Updating a Project Database to the latest version. Maintenance mode is controlled by setting a value for the Maintenance extended property associated to dbo.Project table.
Use Microsoft SQL Management Studio as follows:
Enable: set value for Maintenance extended property 1.
Disable: set value for Maintenance extended property 0.
