Special Operations Menu

The Special Operations menu provides the ability to turn traces on or off, create or configure and delete servers, display various statistics, and start and stop the application of updates to the slave. To enter this menu, select the Special Operations option from the Hot Backup Main Menu.

 

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. Messages display in reverse chronological order (most recent first). The server does not need to be running to use this command.

Turn traces ON

Turns traces ON for debugging purposes on the selected server. Traces can considerably slow server performance and should set to OFF in normal operations.

Turn traces OFF

Disables traces on the selected server.

Setup server

Opens the Setup Server Utility which allows you to create or edit a Hot Backup server.

Delete Server

Deletes the selected server definition. If more than one server exists, the list of available servers displays.

List permanent log

Lists the permanent log of all messages logged by all servers. These keystrokes allow you to navigate the log:

  • CTRL+N to scroll forward through the logs

  • CTRL+B to scroll backward through the logs

  • T to jump to the top of the log

  • B to jump to the bottom of the log

  • : to enter a special command line that allows searching for the first log entry entered after a given date or time, and searching for a string

  • Q or ESC to return to the Special Operations menu

Clear Permanent log

Clears the permanent log file. Three clear options are available:

  • 1 Clear all entries

  • 2 Clear entries older than 1 week

  • 3 Clear entries older than 1 month

Stop Applying Updates

For slave servers only. Instructs the selected server to stop applying updates coming from its associated master server, and instead stores the updates in the hb.log,apply temporary hold file. Selecting this option also updates the server configuration. Thus, the next time the server is started, updates are not applied.

To display the number of pending updates, select the Query Server option from the Hot Backup Main Menu. To re-apply updates, select the (Re)start applying updates option.

NOTE—If Hot Backup is not running from the dm account, the apply data level must be created in the hb.log file in the dm account on both the master and slave servers before using this option. To create the apply data level, enter the command below in the dm account at TCL:

create-file hb.log,apply 301 (x

(Re)Start Applying Updates

For slave servers only. Applies any pending updates to the database and restarts the normal state of applying new updates as they arrive. Selecting this option also updates the server configuration. Thus, the next time the server is started, updates are applied.

Close opened files

For slave servers only. If it becomes necessary to delete a file on the slave server (for example, after recovering from a missing file-of-files item on the master server (see the error message Cannot read FOF item)), the slave server must be instructed to close all the files it opened. If the files are accessed again, the slave server reopens them.
