Menu

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.
