The state filter bar allows you to display specific states in the view. For a Teradata Database system, if the number of states exceeds the available space, you can select another state from the Overflow Menu. The new state replaces the last state on the state filter bar.



The state filter buttons provide a count of sessions for each state category. Click a state in the state filter bar to display only sessions with a query in the selected state. For example, click Delay to display the sessions running a query that is queued and waiting to run. Hover over a state filter button to display the full state name or number.

Response-Held
In SLES 11, sessions running a query whose response is being held until a specified number of seconds elapses
Direct Blockers*
Sessions that immediately block the current session

For example, if session 1 is blocking session 2, which in turn is blocking session 3, the Blocked By tab for session 3 shows both sessions 1 and 2 under All. Under Direct Blockers, it shows only session 2.

Root Cause*
Sessions that are not blocked, but are causing other sessions to be blocked
Granted*
Sessions that are blocked and are blocking other sessions because they have been granted a lock
Waiting*
Sessions that are blocked and are ahead of other blocked sessions in the queue

*Appears when By Blocker has been selected from the menu and when connected to Teradata Database 15.0 and later.
