The state filter bar allows you to display specific states in the view. For a Teradata 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.
Teradata System States
- All
- Sessions in the system
- Not Idle
- Sessions in any state except idle
- Active
- Sessions processing queries
- Block
- Sessions processing a query waiting for a locked resource, such as a database table or view
- Deferred
- Sessions running a query that is in deferred queue waiting to run.
- Delay
- Sessions waiting to be processed
- Abort
- Sessions in the process of aborting (rolling back changes made by the query)
- Resp
- Sessions running a query that has completed and is sending (responding) spooled data back to the user
- Idle
- Sessions not currently running a query
- Parse
- Sessions running a query that is being parsed and has not begun to execute
- Other
- Sessions whose status is unknown and do not fall into another category
- QTDelayed
- Sessions delayed due to a queue table restriction
- SesDelayed
- Utility sessions that are in the workload delay queue
- 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*
