It can be very helpful to filter the results of sp_who2 in SQL 2008:
DECLARE @sp_who2_temp_table TABLE( SPID INT, Status VARCHAR(100), LOGIN VARCHAR(150), HostName VARCHAR(100), BlkBy VARCHAR(100), DBName VARCHAR(100), Command VARCHAR(250), CPUTime INT, DiskIO INT, LastBatch VARCHAR(100), ProgramName VARCHAR(254), SPID_1 INT, REQUESTID INT ) INSERT INTO @sp_who2_temp_table EXEC sp_who2 SELECT * FROM @sp_who2_temp_table WHERE DBName = 'DatabaseName'
Study the blocking query:
-- Enter SPID DBCC INPUTBUFFER(77)
Use sp_who2 to find any running query, or the following query to view jobs and percent complete:
SELECT R.percent_complete, T.text, R.Status, R.Command, DatabaseName = db_name(R.database_id) , R.cpu_time, R.total_elapsed_time, R.percent_complete FROM sys.dm_exec_requests R CROSS APPLY sys.dm_exec_sql_text(R.sql_handle) T ORDER BY Command
Enjoy the results!
