JEUS WebAdmin provides a configuration lock feature for a specific user, not for a session. Only the user who has the lock can change the configuration.
The user has the lock until the user clicks [Apply Changes] to apply the changes or [Undo All Changes] to revert the changes. As long as the lock is not returned, the user can continue editing even if the user logs out and logs back in again.
Acquiring the Lock
The lock is not automatically returned. If the user does not return the lock, other users cannot make changes. To prevent this from occurring, other users can forcibly acquire the lock as in the following example.
-
A user, user1, logs in and acquires the lock by clicking [Lock & Edit]. The user does not apply or revert the changes, and logs out while still in the Lock & Edit mode.
-
Another user, user2, logs in.
-
If user2 clicks [Lock & Edit] to try to change the configuration, the following warning message is displayed that says another user is using the Lock & Edit mode.
User2 acquires the lock by clicking [Force Lock].
Caution
When the lock is forcibly acquired, all changes made by the previous lock owner are lost.
-
The configuration screen changes to the following Lock & Edit mode.
