Application Server Page

The Application Server Page groups together information about the database published by 4D Server and can be used to manage this publication:

The upper part of the page provides information about the current status of the 4D Server application server.

• State: Started or Stopped.
• Starting time: Date and time the server database was launched. This date corresponds to the opening of the database by 4D Server.
• Uptime: Time elapsed since last opening of database.

This button toggles and can be used to manage the access of new client machines to the application server.

• By default, when the database is published:
  
  • The button is titled "Reject new connections."
  • New clients can connect freely (within the limit of the connections permitted by the license).
  • The database name is published in the connection dialog box (if the "At Startup Publish Database Name in the Connection Dialog" option is checked in the Preferences).

• If you click on the Reject new connections button:
  
  • The button title changes to "Accept new connections."
  • No new client can then connect.
  • The database name no longer appears in the connection dialog box.
  • Clients that are already connected are not disconnected and can continue to work normally.
  • If you click on the Accept new connections button, the database returns to its default state.

This area provides information about the 4D database published by the server: name and location of data and structure files and name of database log file. You can click on the structure or data file name in order to view its complete pathname:

The "Mode" field indicates the current execution mode of the database: compiled or interpreted.

The lower part of the area indicates the server configuration parameters (launched as service, port and IP address) and the enabling of SSL for client-server connections (does not concern SQL nor Web connections).

This area indicates the Total cache memory (parameter set in the database Preferences) and the Used cache memory (dynamic allocation by 4D Server according to its needs).

"Maximum:" indicates maximum number of simultaneous client connections allowed for the application server. This value depends on the license installed on the server machine.

"Used:" indicates actual number of connections currently being used.
