To interrupt one or more users
In the Users view, right-click on the user who you want to conditionally interrupt on a specific node. Alternatively, use the Ctrl or Shift key to select a group or range of users, respectively.
Select the Interrupt User command from the popup menu that is displayed. This command is disabled if no user is currently selected in the Users view.
A message box is then displayed, prompting you to click the OK button to confirm that you do want to interrupt the selected user or users on the node. (Alternatively, click the Cancel button to abandon the interrupt action and allow the user or users to continue uninterrupted.)
You can use this command to interrupt a database operation. This action cancels (that is, performs a user abort action of) an in-progress file certify, file compact, file reindex, file freespace evaluate, file usage analysis, make file partitioned, and move instances database operations, and in-progress reorganizations.
