    SHUTDOWN

    The server was shut down normally or has not been started.

Edit mode, in which settings can be modified, can be activated in two ways.

figure webadmin editmode
Edit Mode

  • ① Lock & Edit

    Click [Edit] at the bottom of the menu section to activate the Lock & Edit state. In this state, edit mode remains active even when navigating between pages.

    After making changes, click [Save] at the bottom to save the modifications temporarily. If you click [Revert], the modifications are canceled.

    Temporary Saving in Lock & Edit State

    After making modification, you can revert all changes or apply them to servers using the buttons at the bottom of the menu section. When applying the modifications to servers, you can add a description of the changes, which will be displayed on the History screen.

    figure webadmin editmode apply
    Applying to Servers in Lock & Edit State

  • ② Auto Lock

    Click the image icon in the header section to display the Auto Lock activation switch.

    Auto Lock can be activated only when Lock & Edit is not active. When Auto Lock is enabled, the [Edit] button appears on certain settings pages, and clicking it activates edit mode, allowing you to modify settings.

    figure webadmin editmode autolock
    Auto Lock Edit Mode

    After making modifications, click [Save] to immediately apply the settings to the server. These modifications are not recorded on the History screen.

3.5. Forcible Lock

The lock is assigned per user rather than session, and only the user who holds the lock can modify or cancel the settings.

Click [Edit] at the bottom of the menu section to enter the 'Lock & Edit' state, which remains active until you either click [Apply to Server] to apply the modifications to servers, or [Revert All Changes] to cancel them.

If a user obtains a lock and does not release it, other users cannot edit settings because the lock is not released automatically. To resolve this, other users are allowed to forcibly take over the lock.

If one user is in the 'Lock & Edit' state and another user clicks [Edit], 'Concurrent Editing Disabled' message appears. The second user can then click [Force Lock] to forcibly obtain the lock and enter edit mode. In this case, any modifications made by the previous user are discarded, but changes that were already applied to servers are remain intact.
