Adding database close options
Note  The following information is for server administrators and group administrators.
1. In the text box, type the message to send to clients before they are disconnected.
Clients see a notification dialog box with your message requesting that they close their connection to a file.
2. For Delay time, enter the number of minutes between when the notification is sent and when clients will be disconnected.
When the delay time elapses, FileMaker Server disconnects any remaining clients and closes the selected databases.
