Check background process from SQL Server

问题

I have a background process running, it can be seen in task Manager while its running. I need to check from my database, whether the process is running or not I have tried the following query

select * from sys.dm_os_threads
select * FROM sys.dm_os_tasks

But it doesnt show me all process running on the system

I hope you are talking about background SQL Server process. Below queries only show information related to SQL Server

All processes running on SQL server can be seen by querying DMV

select * from  sys.dm_exec_requests
select * from sys.dm_exec_sessions 
select * from sys.dm_exec_connections

You can read books online about the documentation about these DMV's

use this query

select 
                 tblSysProcess.cmd
               , tblSysProcess.physical_io IOUsage
               , tblSysProcess.cpu as CPUusage
               , tblSysProcess.waittype as waitType
               , tblSysProcess.waittime as waitTime
               , tblSysProcess.lastwaittype as lastWaitType
               , tblSysProcess.waitResource as waitResource
               , tblSysProcess.dbid as databaseID
               , case
                     when (dbid > 0) then db_name(dbid) 
                     else ''
                 end as dbName
               , memusage as memUsage
               , status

       from  master.dbo.sysprocesses tblSysProcess

       where 

              (

                  --background process    
                  (tblSysProcess.spid < 50)

              )

回答3:

select db_name(dbid),cmd,spid,status 
from 
    sys.sysprocesses 
        where 
            db_name(dbid) = 'dbname' and status = 'background'

So it looks like you're not trying to see a SQL server process but another process on the machine for another application, none of the built in DMVs or functions will be able to show you this information natively. You have a couple of options, one is to write a CLR stored proc or function to check for the process, the other is to use xp_cmdshell to get the tasklist, you can do that like this:

EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO
EXEC xp_cmdshell 'tasklist.exe'
GO
EXEC sp_configure 'xp_cmdshell', 0
RECONFIGURE

That will list out all the running processes on the machine, you could shove that data into a table if you like for further analysis if required, or you can play with the tasklist.exe parameters to just look for the process that you are interested in. Just remember to turn off xp_cmdshell whenever you don't need it as it can be a security risk.

Try This;

EXEC sp_who1

EXEC sp_who2

SELECT *
FROM   MASTER..sysprocesses

SELECT *
FROM   sys.dm_exec_sessions
WHERE  is_user_process = 1
