Main Menu

The Hot Backup Main Menu provides the ability to start and stop a server, display various statistics, and open other Hot Backup menus.

Menu Option	Description
Status	Displays the last messages displayed by the selected server. The title of the message section on the screen indicates the server name and additional information. The messages display in reverse chronological order (most recent first). The server does not need to be running to use this command.
Query Server	Queries the selected server. The server must be running. See Querying servers for more information.
Start Server	Starts the selected server. Note: During a coldstart, D3 automatically starts the last Hot Backup server that was started before the coldstart.
Stop Server	Stops the selected server.
Show Server	Displays the current configuration of the selected server. Type `Y` to return to the Hot Backup Main Menu.
Show statistics	Displays transaction statistics. Both servers must be running. If run on the slave server, the result displays immediately. If run on the master server, a request is sent to the slave server, and statistics display later. The response time depends on how busy the slave server is. The slave server accumulates the statistics. Statistics are cleared with each slave server restart. Note: You can use this option from the master server to determine whether communication is established.
Display queue	For master servers only. Displays the status of the transaction log queue. The information below displays: Number of frames in queue. This is a rough indication of the amount of data not yet transmitted. Whether the system is set up to log all files or only DL files. Whether file updates are enqueued globally. Current transaction number being transmitted, if nonzero. Last acknowledged transaction number. This is the last transaction that was received and successfully processed by the associated slave server. If the last `ACK` number is not reported, the query was performed at a moment when all transactions are acknowledged. First transaction not yet acknowledged by the associated server. This can be an update item, a delete item, and so on. In case of a problem, this is the first transaction that is retransmitted.
Special Operations	Opens the Special Operations menu which allows you to perform miscellaneous operations such as setting up traces, servers, permanent log files, and applying updates.
Transaction log menu	Opens the Transaction Log menu which allows you to perform several transaction log operations.
