In rare cases when a request completes (or is aborted), the spool file is not dropped. The leftover spool may be:
Execute the following query to determine the presence of leftover spool of either type:
SELECT Databasename, Vproc, CurrentSpool
FROM DBC.Diskspace
WHERE Databasename NOT IN (SELECT Username FROM DBC.SessionInfo)
AND CurrentSpool > 0
ORDER BY 1,2
WITH SUM (CurrentSpool);
If this request returns rows, the next step is to run the Update Space (updatespace) utility.
The Update Space utility can also be used to correct inconsistencies in the DBC.DatabaseSpace table, which might occur because of unusual types of system failures.
